A Quirk in SPACE-TIME

The fabric of space and time is not exempt from the effects of gravity. Plop in a mass and space-time curves around it, not dissimilar to what happens when you put a bowling ball on a trampoline.


This dimple in space-time is the result of what we call a gravity well, and it was first described over 100 years ago by Albert Einstein's field equations in his theory of general relativity. To this day, those equations have held up. We'd love to know what Einstein was putting in his soup. Whatever it was, general relativity has remained pretty solid.


One of the ways we know this is because when light travels along that curved space-time, it curves along with it. This results in light that reaches us all warped and stretched and replicated and magnified, a phenomenon known as gravitational lensing. This quirk of space-time is not only observable and measurable, it's an excellent tool for understanding the Universe.         READ MORE...

Possible Alien World

Possible alien world bubbling over with volcanoes detected deep in space

It’s thought that there is at least one planet for every star in the galaxy. That means that there are billions of planets in our galaxy alone, and many of these could be in Earth’s size range. So far, researchers think they have found 5,000. But now, one research team has possible evidence that they have found an exoplanet [meaning a planet outside the solar system] with a sulphur-rich atmosphere deep into space (Picture: Getty)     READ MORE...

A Star Older Than the Universe

For as long as humans have contemplated the Universe, we’ve marveled at the vastness of it all. Was our Universe infinite? Was it eternal? Or did it spring into existence a finite amount of time ago? Over the 20th and 21st centuries, these existential questions for all-time have, one-by-one, fallen into the realm of science, and now have the best answers we’ve ever been able to assemble. 

As of today, in 2024, we can confidently state that we actually know how old the Universe is: 13.8 billion years old, marking time at the start of the hot Big Bang. If we could step back through time, we’d find that the universe as we know it was a very different place early on. Modern stars and galaxies arose from a series of gravitational mergers of smaller-mass objects, which themselves consisted of younger, more pristine stars. 

At the earliest times, there were no stars or galaxies, and even farther, no neutral atoms or stable atomic nuclei, going all the way back to the hot Big Bang. Today, astronomers and astrophysicists who study the early universe confidently state its age with an uncertainty of no more than ~1%: a remarkable achievement.      READ MORE...

A Dark Primordial Galaxy

Astronomers have accidentally discovered a dark galaxy filled with primordial gas untouched that appears to have no visible stars.


The researchers behind the discovery say this galaxy, designated J0613+52, could be "the faintest galaxy found to date." Interestingly, scientists using the Green Bank Telescope (GBT) discovered the "dark" galaxy through a complete error.

"The GBT was accidentally pointed to the wrong coordinates and found this object. It's a galaxy made only out of gas — it has no visible stars," Green Bank Observatory senior scientist Karen O'Neil said in a statement. "Stars could be there. We just can't see them."  READ MORE..

Star Older Then Universe

The star HD 140283 has been called the "Methuselah star" for its extreme age. At an estimated over 14 billion years old, it’s the oldest star we know, at least within our galaxy. A star that old is certainly interesting, particularly when it is so close to us it can be seen with binoculars, however, that appears to put it older than the universe. How that can be? A closer examination reveals the star is special, but not that special.


The standard estimate of the time since the Big Bang is 13.79 billion years. The figure is derived from the rate of expansion of the universe using Einstein's relativity but has been validated through a variety of methods. However, that number is now facing at least three distinct challenges. As evidence, proponents point to the existence of stars estimated to be either older than 13.8 billion years, or so close to that age that there shouldn’t have been time for them to form.


Not surprisingly HD 140283 gets prime billing (helped by its catchy nickname derived from a Biblical ancestor of Noah said to have lived to 969) due to a 2013 study using Hubble data that estimated it is 14.46 billion years old, plus or minus 800 million years. That would make it potentially older than the universe.


The biggest claim regarding HD 140283 is that it disproves the Big Bang. After all, if there is even one star 14.5 billion years old then the explosion that started the universe couldn’t have happened less than 14 billion years ago. The Big Bang is now so central to our cosmology that were it to be disproved it would create a scientific revolution the like of which we have not seen for a long time.


A smaller, but still dramatic, change would be required to adapt to the recent claim that the Big Bang happened, but almost twice as long ago as most estimates put it, at 26.7 billion years ago.


Neither of these views has much support among astrophysicists, but some do suspect we’ve got our estimates of the timing of the Big Bang more modestly wrong, and the universe is really around 15 billion years old. Although such an estimate would raise a few questions about why our estimates for the universe’s expansion rate are out, if proven, accompanying changes to our thinking would be evolutionary not revolutionary.

In that context, it’s worth asking: if the universe was 26 billion years old, wouldn’t we expect to find 20 billion-year-old stars? It’s true we’ve only really looked across a small portion of the galaxy, but if the universe is that old, Methuselah looks suspiciously young. Then take that question a step further and ask what we might expect to see if the universe had no beginning and has always been here.  READ MORE...

Talking to Voyager Again

NASA’S VOYAGER 1 is on a fraught and unknowable journey into deep space. Some 14.6 billion miles from Earth, it and its sister craft, Voyager 2, are the furthest human-made objects from our planet, having made it beyond the edges of the Solar System and out into the interstellar medium. 

At such distances, anything can go wrong. Add to that the fact that these are old craft: The Voyagers launched in the 1970s. 

So when Voyager 1 started to send home weird, garbled nonsense instead of telemetry data in May of this year, NASA engineers might have been forgiven for calling it a day and pouring one out for perhaps the most successful space mission of all time.


But that’s not how NASA works. Instead, they started working on a remote diagnosis and fix for the record-breaking spacecraft. Now, some four months later, they are triumphant. 

Voyager 1 is back online and communicating perfectly with ground control as if it never happened. In fact, the fix turned out to be relatively simple — or as simple as anything can be with a 22-hour communications lag in each direction and billions of miles of space in between.  READ MORE...

Tracing Earth's Path Through the Galaxy

"To see a world in a grain of sand," the opening sentence of the poem by William Blake, is an oft-used phrase that also captures some of what geologists do.




We observe the composition of mineral grains, smaller than the width of a human hair. Then, we extrapolate the chemical processes they suggest to ponder the construction of our planet itself.

Now, we've taken that minute attention to new heights, connecting tiny grains to Earth's place in the galactic environment.

Looking out to the universe
At an even larger scale, astrophysicists seek to understand the universe and our place in it. They use laws of physics to develop models that describe the orbits of astronomical objects.

Although we may think of the planet's surface as something shaped by processes entirely within Earth itself, our planet has undoubtedly felt the effects of its cosmic environment. This includes periodic changes in Earth's orbit, variations in the sun's output, gamma ray bursts, and of course meteorite impacts.

Just looking at the Moon and its pockmarked surface should remind us of that, given Earth is more than 80 times more massive than its gray satellite. In fact, recent work has pointed to the importance of meteorite impacts in the production of continental crust on Earth, helping to form buoyant "seeds" that floated on the outermost layer of our planet in its youth.

We and our international team of colleagues have now identified a rhythm in the production of this early continental crust, and the tempo points to a truly grand driving mechanism. This work has just been published in the journal Geology.  READ MORE...

Snake Like Galaxy

The European Southern Observatory’s Very Large Telescope (VLT) and Atacama Large Millimeter/submillimeter Array (ALMA) have imaged a snake-like galaxy. Scientists named the galaxy NGC 1087, and it is swirling through space almost 80,000 light-years from our planet.


ALMA’s image of this snake-like galaxy is breathtaking
The snake-like galaxy spans over 86,800 light-years across. It can be found within the constellation Cetus. This particular part of the sky is home to several other water-themed constellations, too, such as Pisces and Aquarius. It isn’t the largest galaxy we have discovered but, it’s still impressive.

They created the main image by combining multiple images from ALMA and the Multi-Unit Spectroscopic Explorer on the ESO’s VLT. This allowed the ESO to create an image that showcases the full galaxy, along with the cold clouds of star-spawning gas that surrounds it. Additionally, the areas tinted with blue represent older stars that are more mature.

Scientists captured the shots as part of a conjunctive project called the Physics at High Angular Resolutions in Nearby Galaxies Survey, or PHANGS. The team assigned scientists to help deliver a catalog of high-resolution observations of nearby galaxies while using telescopes that target a wide range of different wavelengths. This snake-like galaxy is just one that the team has seen.

And ALMA is perfect for capturing images of galaxies like this because of how high up it is. The observatory is located at an altitude of 5,000 meters (16,500 feet) in Chile. As such, it has an excellent vantage point for the 66 radio telescopes the observatory is equipped with.  READ MORE...

Unknown Structure in Galaxy

As a result of achieving high imaging dynamic range, a team of astronomers in Japan has discovered for the first time a faint radio emission covering a giant galaxy with an energetic black hole at its center. 

The radio emission is released from gas created directly by the central black hole. The team expects to understand how a black hole interacts with its host galaxy by applying the same technique to other quasars.

3C273, which lies at a distance of 2.4 billion light-years from Earth, is a quasar. A quasar is the nucleus of a galaxy believed to house a massive black hole at its center, which swallows its surrounding material, giving off enormous radiation. 

Contrary to its bland name, 3C273 is the first quasar ever discovered, the brightest, and the best studied. It is one of the most frequently observed sources with telescopes because it can be used as a standard of position in the sky: in other words, 3C273 is a radio lighthouse.

When you see a car's headlight, the dazzling brightness makes it challenging to see the darker surroundings. The same thing happens to telescopes when you observe bright objects. Dynamic range is the contrast between the most brilliant and darkest tones in an image. 

You need a high dynamic range to reveal both the bright and dark parts in a telescope's single shot. ALMA can regularly attain imaging dynamic ranges up to around 100, but commercially available digital cameras would typically have a dynamic range of several thousands. Radio telescopes aren't very good at seeing objects with significant contrast.  READ MORE...

A Spectacular Universe

Just 12 million light-years away, the galaxies Messier 81 and 82 offer a nearby preview of the Milky Way-Andromeda merger.

Right in our cosmic backyard, a preview of the Milky Way’s future unfolds.
The galaxy Messier 81, also known as Bode’s Galaxy, is one of the brightest and closest galaxies to Earth not found in our Local Group. By connectng the lower-left corner of the Big Dipper’s cup to the upper-right corner and then traveling that same distance in the same direction, you can find M81 and the other major galaxies of its group all clustered together.

Just outside the Big Dipper’s “cup,” Bode’s Galaxy, Messier 81, lingers.
This optical image of Bode’s Galaxy, M81, comes courtesy of the Hubble Space Telescope.

Radio Signals From Milky Way

Mysterious radio waves emanating from the center of the galaxy have astronomers stumped.
Four objects have briefly emitted radio signals that don't resemble any known type of star.
Scientists think each of the four signals could come from a new type of object unknown to astronomy.

Ziteng Wang found a needle in an astronomical haystack.

Wang, a physics PhD student at the University of Sydney, was combing through data from Australia's ASKAP radio telescope in late 2020. His research team had detected 2 million objects with the telescope and was classifying each one.

The computer identified most of the stars, and the stage of life or death they were in. It picked out telltale signs of a pulsar (a rapidly rotating dead star), for example, or a supernova explosion. But one object in the center of our galaxy stumped the computer and the researchers.

The object emitted powerful radio waves throughout 2020 — six signals over nine months. Its irregular pattern and polarized radio emissions didn't look like anything the researchers had seen before.

Even stranger, they couldn't find the object in X-ray, visible, or infrared light. They lost the radio signal, too, despite listening for months with two different radio telescopes.

It reappeared suddenly, about a year after they first detected it, but within a day, it was gone again.  READ MORE...

Stellar Cocoon With Organic Molecules

For the first time, astronomers have detected a newborn star and the surrounding cocoon of complex organic molecules at the edge of our Galaxy, which is known as the extreme outer Galaxy. The discovery, which revealed the hidden chemical complexity of our Universe, appears in a paper in The Astrophysical Journal.

The scientists from Niigata University (Japan), Academia Sinica Institute of Astronomy and Astrophysics (Taiwan), and the National Astronomical Observatory of Japan, used the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile to observe a newborn star (protostar) in the WB89-789 region, located in the extreme outer Galaxy. 

A variety of carbon-, oxygen-, nitrogen-, sulfur-, and silicon-bearing molecules, including complex organic molecules containing up to nine atoms, were detected. Such a protostar, as well as the associated cocoon of chemically-rich molecular gas, were for the first time detected at the edge of our Galaxy.

The ALMA observations reveal that various kinds of complex organic molecules, such as methanol (CH3OH), ethanol (C2H5OH), methyl formate (HCOOCH3), dimethyl ether (CH3OCH3), formamide (NH2CHO), propanenitrile (C2H5CN), etc., are present even in the primordial environment of the extreme outer Galaxy. Such complex organic molecules potentially act as the feedstock for larger prebiotic molecules.

Well...

 Prove It...

I was raised Methodist, attended Episcopal and Baptist for a while but then decided that my faith was more spiritual than institutional and decided I needed to teach myself a thing or two...  so, I read the Bible (cover-to-cover) taking notes and writing down questions... and discovered there was a lot of information that these religious institutions were omitting...  at least not wanting to share with their congregations.

As part of my spiritual journey, I discovered that there were 12 major religions in the world today, so I decided to learn a little bit about each one of them...  I also read the mythologies of countries all over the world, most of which formed the basis for their religious beliefs.

In all these religions and mythologies, I found similarities about:

• Creation
• God/gods
• Heaven/Hell
• Life After Death
• A Great Flood
• Virgin Birth
• Death of Savior
• Teaching Mankind

So... which religion is correct?

Or...  are all of them correct?

Could God have given them a slightly different story based upon their location and circumstances?

As my self-education continued, I became involved with astronomy, cosmology, theoretical physics, quantum mechanics, string theory, and Stephen Hawking's theory of Spontaneous Creation...  all of which underscored the overwhelming magic of our universe and how it it practically impossible for this type of detail to have arisen out of random chaos brought about by expansion from a big bang.

Since, I was not finding anything substantial on which to hang my spiritual beliefs, I got involved with a program entitled ANCIENT ALIENS...  and, the more I watched that show, the more everything about which I was thinking made sense...

There is a God...  and, there were gods...  all of whom were extraterrestrials from another planet in another solar system in another galaxy and quite possibly from another dimention or even a parallel universe...  we are not alone...  and, when they came to visit us, and supply us with knowledge to grow our civilizations we began to think of them as a God or many gods...

Mankind is THEIR CREATION...  we are even perhaps created or genetically modified in their image...  these aliens or extraterrestrials altered our DNA to push us quicker along our evolutionary path...  they gave some of us knowledge in the hopes that it would be shared with others like:  Einstein, Tesla, DaVinci, Von Braun, and Turing among others who had knowledge ahead of their time.

What really strikes me and sometimes causes chills to race inside me is when I think about what Jesus said to Pilot:  "My Kingdom is not of this world."  How profound is this?  Obviously, the world about which he was speaking was EARTH...  so where is his kingdom?  

• Another Planet?  
• Another Solar System?  
• Another Galaxy?  
• Another Dimension?  
• Another Universe?

Why haven't any of our ministers, priests, pastors, or other members of the clergy explained this kingdom of his in terms that made some kind of logical sense other than saving, he was talking about heaven...?

Don't they owe us that much courtesy?

SO...  my faith is based upon my spiritual journey that continues everyday as I search for more clues as to what is really going on...

AND...  one final thought to leave you with...

if we were created on this planet called earth thousands of years ago, why hasn't our eyes adjusted to the sun because many of us still have to wear sunglasses outside when the sun is shining...  and, why hasn't our skin adjusted either because if we are out in the sun too long without protection, we get sunburn...  don't you think evolution would have caused our bodies to adjust to this sun by now?

The Einstein Ring

The Hubble Space Telescope captured a stunning ‘Einstein Ring’ 3.4 billion light-years from Earth.

This cosmic display, formally known as gravitational lensing, occurs when the gravitational field from a massive object in space warps space and deflects light from a distant object behind it.

It then results in a bull’s-eye pattern, or ‘Einstein Ring.’ It was predicted by the famed physicist, Albert Einstein, in 1915.

The image shows six luminous spots of light clustered at the center, four of which are forming a circle around a central pair.

The formation, however, only consists of two galaxies and a single distant quasar that is magnified as it passes through the gravitational field of the galaxies.

The Hubble Space Telescope captured a stunning ‘Einstein Ring’ 3.4 billion light-years from Earth

The quasar, known as 2M1310-1714, sits farther away from Earth than the pair of galaxies.

A quasar is the extremely bright nucleus of an active galaxy and its powerful glow is created by the incredible amounts of energy released by gas falling toward the supermassive black hole at its center.   READ MORE

Milky Way Streaking

In 2017, astronomers noticed a star streaking out of the Milky Way at nearly 2 million mph (3.2 million km/h) — roughly four times faster than our sun orbits — and flying against the direction in which most stars trek around the galactic center. 

It's also made of completely different star stuff, mostly heavy, "metallic" atoms rather than the usual light elements. 

LP 40-365, as it was called, was as eye-catching as a wooden car barreling up the interstate against traffic at hundreds of miles per hour.

"It is exceptionally weird in a lot of different ways," said study lead author J.J. Hermes, an astronomer at Boston University.

The star moves so quickly that it's headed out of our galaxy for good, which astronomers have taken as evidence that the metallic explorer was launched here by a cosmic catastrophe — a supernova. 

But they couldn't tell how the supernova had sent it flying. Was LP 40-365 a piece of the exploded star itself? Or was it a partner star flung clear by the shockwave associated with star explosions? 

A new analysis of old data finds that the star — called a white dwarf — spins about its axis at a leisurely pace — a hint that it is indeed a piece of stellar debris (not a partner star) that managed to survive one of the galaxy's most violent and mysterious events.

"We can now connect this star to the shrapnel from an exploded white dwarf with a lot more confidence," said Hermes.  READ MORE

Searching For Alien Life

Is mankind alone in the universe? Or are there somewhere other intelligent beings looking up into their night sky from very different worlds and asking the same kind of question? Are there civilizations more advanced than ours, civilizations that have achieved interstellar communication and have established a network of linked societies throughout our galaxy? 

Such questions, bearing on the deepest problems of the nature and destiny of mankind, were long the exclusive province of theology and speculative fiction. Today for the first time in human history they have entered into the realm of experimental science.

From the movements of a number of nearby stars we have now detected unseen companion bodies in orbit around them that are about as massive as large planets. From our knowledge of the processes by which life arose here on the earth we know that similar processes must be fairly common throughout the universe. 

Since intelligence and technology have a high survival value it seems likely that primitive life forms on the planets of other stars, evolving over many billions of years, would occasionally develop intelligence, civilization and a high technology. Moreover, we on the earth now possess all the technology necessary for communicating with other civilizations in the depths of space. Indeed, we may now be standing on a threshold about to take the momentous step a planetary society takes but once: first contact with another civilization..

In our present ignorance of how common extraterrestrial life may actually be, any attempt to estimate the number of technical civilizations in our galaxy is necessarily unreliable. We do, however, have some relevant facts. There is reason to believe that solar systems are formed fairly easily and that they are abundant in the vicinity of the sun.  In our own solar system, for example, there are three miniature "solar systems": the satellite systems of the planets Jupiter (with 13 moons), Saturn (with 10) and Uranus (with five). 

The only technique we have at present for detecting the planetary systems of nearby stars is the study of the gravitational perturbations such planets induce in the motion of their parent star. Imagine a nearby star that over a period of decades moves measurably with respect to the background of more distant stars. Suppose it has a nonluminous companion that circles it in an orbit whose plane does not coincide with our line of sight to the star. 

Both the star and the companion revolve around a common center of mass. The center of mass will trace a straight line against the stellar background and thus the luminous star will trace a sinusoidal path. From the existence of the oscillation we can deduce the existence of the companion. Furthermore, from the period and amplitude of the oscillation we can calculate the period and mass of the companion. The technique is only sensitive enough, however, to detect the perturbations of a massive planet around the nearest stars.  TO READ MORE, CLICK HERE...

A Dying Galaxy

From the smallest microbe to the mightiest oak, death is as true for above as it is for below, even for the mightiest galaxies.

The process, however, is not a quick one. A haunting new Hubble photo of the galaxy NGC 1947 demonstrates this well: Even from a distance of around 45.4 million light-years away (in the southern constellation of Dorado), we can see that the galaxy is slowly on the decline.

The clue lies in the dust and gas. A galaxy in the prime of its life will be filled with the stuff, using it to make new stars. Eventually, the star-stuff will run out, and that's what astronomers believe we are seeing with NGC 1947.

It's a rare type of galaxy known as a lenticular galaxy - disk-shaped, like the Milky Way or Andromeda, but without the spiral arms. NGC 1947 used to have spiral arms, but it has used up almost all the gas and dust that gave them structure; all that remains is a few wisps, backlit by starlight.  Read More

ANCIENT ALIENS

History Channel
15 Seasons - first episode April 20, 2010
Investigators circle the globe in search of evidence in their quest to determine whether life on Earth began in outer space and if aliens influenced mankind in ancient times. Did extraterrestrial beings visit Earth and share information about technology and influence human religions?

Erich von Daniken's Chariots of the Gods  (first published January 1968) is a work of monumental importance--the first book to introduce the shocking theory that ancient Earth had been visited by aliens. This world-famous bestseller has withstood the test of time, inspiring countless books and films, including the author's own popular sequel, The Eyes of the Sphinx.               

Outside of College textbooks, this was one of the first books that I purchased in the 60's because of limited financial resources.  I remember reading this book 2-3 times before I started acquiring more books on the subject of extraterrestrials visiting earth.  Given the size of our universe, it just seemed highly logical and extremely probable that the human race was NOT ALONE...

SO...  let me give you an idea of how big our universe is.  First of all, you must understand that our EARTH lives inside a solar system and that solar system is a small part of our Milky Way Galaxy.  While  the diameter of the Milky way varies although for the most part is ~ 100,000 light years; therefore, the diameter of the Milky way is roughly 160,256,410 times as wide as the solar system.

Two Trillion Galaxies in the Universe

Just think about this for a minute...  160,000,000+ times as wide... 


It would take TWO BILLION YEARS cross the Milky Way Galaxy at LIGHT SPEED.


NOW, scientist believe there are TWO TRILLION Galaxies in the UNIVERSE.

Given this knowledge, it would be absolutely ludicrous to believe or even perceive that we are the only living SPECIES in the Universe.
