Tachyons Are Cosmic Engines of Time Travel

Interstellar travel is the greatest challenge mankind will ever face. Not only because it’s so grandiose and marked by impressive shimmering spacecraft — tall and boundless, scaled by materials born of human ingenuity — but because it’s a necessary step in exploration and understanding of the cosmos.
It becomes ever more necessary as time goes on, and ever more difficult. This is the complication we face.
Soon, even speeds approaching that of light may not be enough as our universe continues to expand at an enormous rate. The light of our closest star systems and galaxies will struggle to make their way to us, their existence visible only in our books and our computer programs which will have to remind us that the surrounding sky didn’t always look so empty.
At lightspeed today travel between star systems would take years for a one-way trip. As much of a feat as luminal speeds are, they may someday prove to be insufficient themselves. But where the speed of light has presented to us an obstruction, so too is there a peculiar hope. There are, after all, two sides to every limit.
A comment Einstein makes in his 1905 paper reads, “…velocities greater than that of light have no possibility of existence.”
But modern science and mathematics have found clever ways around this, loopholes which permit superluminal speeds without contradicting the theory of relativity. READ MORE...
Filing Our Taxes
The extension gives us an extra 6 months before we have to file our taxes for the previous year. That new deadline is October 15. So, sometime around the end of September, we get with our tax preparer with our K-1s to file our taxes.
Many people prepare their own taxes to save the money of having to pay a tax preparer... but we pay our tax preparer $100 so it saves a lot of hassle for just a little amount of money. This year we get back $120 and paid out $100 plus a little bit of our time.
While we were there we asked if she could project out taxes for the next year. After making a few assumptions, it took her 5 minutes to get the answer. Yes... next year we will be paying a hell of a lot more in taxes than we paid this year.
REASON: We made a shitload of money by investing in high yield CDs over a period of 18 months although we are only looking at 12 of those 18 months.
The way that it will work out for us is that our taxes will represent about 11% of what we earned. This means, we will be able to keep 91% of our earnings which is not a bad return.
Because we are in the state of Tennessee, our Social Security is not taxed.
If we calculate the taxes we will pay as a percentage of our total income for that year, it will be 6%. Again, we will be able to keep 94% of our total income for that year.
Our positive situation is directly related to the amount of money that we have been able to save over the course of our lifetimes.... or at least up until we retired.
The money you earn while you are working is typically used to pay a mortgage, school loans, food, utilities, insurance, car payments, etc. More often than not, couples today do not save money for retirement. They also acquire lots of debt that must be serviced before they retire.
POOR FINANCIAL PLANNING leads to a devastating retired lifestyle...

Inbreeding Can Be Beneficial
The Svalbard reindeer, despite significant inbreeding and low genetic diversity, boasts a robust population of over 20,000, having adapted to Arctic conditions with unique traits like smaller size and the ability to digest mosses. Although they have evolved rapidly to past environmental changes, scientists fear the pace of current global warming may outstrip their capacity to adapt, posing a serious threat to their survival.
Reindeer have endured for over 7,000 years on the Arctic archipelago of Svalbard. Will they be able to withstand climate change?
Despite the challenges of inbreeding and limited genetic diversity, the Svalbard reindeer have remarkably adapted to harsh living conditions in an extraordinarily short period, a situation researchers term a genetic paradox. However, the question remains: can they withstand the impacts of climate change?
“Of all the subspecies of reindeer found in the high north, the Svalbard reindeer has the most inbreeding and the lowest genetic diversity,” says Nicolas Dussex, a postdoc at the Norwegian University of Science and Technology’s (NTNU) Department of Natural History.
It was only 7000-8000 years ago that the first reindeer migrated to Svalbard, most likely from Russia via Novaya Zemlya and the islands of Franz Josef Land. Perhaps there were no more than a few animals that established themselves on the Arctic archipelago. Evolutionary theory suggests this is a poor starting point since inbreeding can quickly lead to an accumulation of harmful mutations and genetic variants followed by disease and death.
But this has not prevented the Svalbard reindeer from evolving into what is today a viable population of more than 20,000 animals.
“Despite the low genetic diversity, they have managed to develop a number of adaptations to life in the High Arctic. They are, for example, smaller in size and have shorter legs than other northern reindeer and caribou subspecies,” says Dussex.
The ability to digest mosses in the absence of lichens, and to adjust their circadian rhythm to the extreme seasonal variations on Svalbard, are also traits the Svalbard reindeer have developed over the relatively short time they have lived isolated on the archipelago.
Now, researchers at NTNU and collaborating institutions have analyzed genetic samples from 91 reindeer to see how they differ from their relatives on the mainland. READ MORE...

The Aging Process
Time moves forward. Each day that passes, we age a little more. As our age increases, the passage of time seems to move faster, even though its rate has not changed at all.
We try to maintain our youth with:
- exercise
- diets
- cosmetics
- surgery
- pills and creams
- hair transplants
- tonics
Some people continue to lift weights and take steroids to keep their bodies lean and mean up until the age of 80 and sometimes beyond... But eventually, bodies break down and muscles atrophy and turn to fat... it is inevitable.
Yet, we pursue this dream and fantasy nonetheless as if we can somehow manage to evade our destiny.
My hair began to turn grey in my twenties and in my forties, I began losing my hair. I just accepted what was happening. I had no desire to try and regrow my hair or change it to another color in an effort to make me look younger.
While I have always been active most of my life until about age 60, I was able to maintain a lean body with a flat stomach, regardless of what I ate or how much of it I ate. That too changed at age 60 and I started gaining weight.
My immediate response was to start exercising... but several physical therapists and doctors told me the only way to lose weight was not by exercise but by reducing the amount of food I ate each day.
As one ages one's metabolism changes and one needs to eat less in order to maintain one's current weight. If one maintains their level of eating, they will automatically gain weight.
I exercise because it helps my heart function properly and because it is a necessary function of recovery from having back fusion surgery. It is not how long I walk but how often I walk. I should be walking for about 15-20 minutes 3 times a day.
Walking used to be a normal easy activity for me to accomplish. I loved to walk and had no problems walking uphill or downhill or flat. I did not walk fast but I did walk at a normal pace. I could walk for a long time like that unless it was unusually hot or cold.
After my back surgery, walking was a chore, and it was like I had to force myself to walk. It was no longer enjoyable. The surgery was successful because I could walk but it changed how I walked.
All this is part of the aging process, and it is something with which we have to accept and move on... otherwise, getting old will leave us miserable.
Einstein Was Wrong About Gravity
Einstein's theory of gravity—general relativity—has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own failure at spacetime singularities inside black holes—and the Big Bang itself.
Unlike physical theories describing the other three fundamental forces in physics—the electromagnetic and the strong and weak nuclear interactions—the general theory of relativity has only been tested in weak gravity.
Deviations of gravity from general relativity are by no means excluded nor tested everywhere in the universe. And, according to theoretical physicists, deviation must happen.
Deviations and quantum mechanics
According to a theory initially proposed by Georges Lemaître and widely accepted by the astronomical community, our universe originated in a Big Bang.
Other singularities hide inside black holes: Space and time cease to have meaning there, while quantities such as energy density and pressure become infinite. These signal that Einstein's theory is failing there and must be replaced with a more fundamental one.
Naively, spacetime singularities should be resolved by quantum mechanics, which apply at very small scales.
Quantum physics relies on two simple ideas: point particles make no sense; and the Heisenberg uncertainty principle, which states that one can never know the value of certain pairs of quantities with absolute precision—for example, the position and velocity of a particle.

This is because particles should not be thought of as points but as waves; at small scales they behave as waves of matter. READ MORE...

A New America
The Republicans have a slim majority in the House and are fighting among themselves for power rather than coming together as a single voice to do battle with the Democrats...
The Democrats have managed to get mainstream media on their side along with the DOJ and the FBI who are not supposed to be political, to take power away from the Republicans...
The citizens of America will soon realize, if they do not already that there are more of them than there are law enforcement personnel whose job it is to force Americans to obey the laws of the land...
The laws of the land, DO NOT APPLY to all the illegal immigrants flowing across our southern borders - If they are willing to break the laws to get here, do you really think they will obey all the other laws once they are here... (Rhetorical Question)
There is a huge push to do away with gasoline vehicles, substituting them for electric vehicles - however, there is currently no infrastructure in place to support all those EVs - this is putting the cart before the horse...
There has been a HUGE INCREASE in illegal drugs and crime in the USA ever since Joe Biden became President - there appears to be a direct correlation here that we are trying to ignore...
Colleges and Universities have diluted and dumbed down their courses so that there are no failures and they can protect their streams of revenues...
China's threat at dominating the world is largely being ignored by the USA authorities because of our nuclear arsenal - they fail to see that this domination will be economical in nature...
The billionaires of the world have a HIDDEN AGENDA that they do not want to share with the rest of the world but it involves destroying the system that made them wealthy in the first place...
For Over Thirty Years Now
Let me explain:
- My wife does all the shopping
- My wife writes all the checks
- My wife balances the check book
- My wife plans out our vacations
- My wife researches for new vehicles
- My wife landscapes the yard outside
- My wife decides on inside decor
- My wife selects all appliances and furniture
- My wife does all the cleaning
- My wife does all the washing and ironing
- My wife does all the interior painting
This not to say that she does not ask for my opinion because she does... so, you could say we decide together, but my responses oftentimes are those she wants to hear.
The reason why she does all of this is because she says her work is better than mine. Whether or not her work is, in fact, better than mine, is not the issue... the issue is that she does it.
I am not in a female led relationship because she has no control over me sexually. I do not sit at her feet waiting for her commands, nor do I share her body with anyone else.
Because she thinks she is better than a man, she does most of the work, they males have typically done in the past.
I mow the lawn and weed eat. I carry stuff into the house and around the house that is too heavy. I do all the driving on the interstate and in places where we have not been before... BUT, when we are at Myrtle Beach, she does all the driving in town. Not sure why or how that got started but it did.
I tell her that she can spend whatever it is that she wants to spend, just don't get us into debt without my agreement, and leave some money left over for me if and when I want to buy something. I typically purchase my laptops and tablets but before I retired from working, I had a subscription to AUDIBLE so I could listen to books in the car while I was driving.
It seems like it is a lopsided agreement especially since most husbands manage the money. Sometimes, the wife and husband will have their own bank accounts and contribute equally or proportionally to monthly expenses... All of our money is in one checking account and one saving account.
Not all women want to be treated like this, but our arrangement has worked out just fine.
ESV: A Lithium Free Battery
Nickel-hydrogen-based batteries that have long been used by NASA for its space missions are now making their way to power the grid. California-based EnerVenue is building large Energy Storage Vessels (ESVs) that could be used to power the grid using renewables, a press release said.
With the world making a major transition to renewables, energy storage solutions are the need of the hour. Lithium-ion batteries have been our best bet so far but making large-scale storage solutions is turning out quite expensive and cumbersome.
Li-ion batteries are prone to thermal runaway and large energy storage solutions need additional facilities for cooling, ventilation, and fire suppression to be built to prevent a major mishap. This is where nickel-hydrogen-based batteries could help.
How does a nickel-hydrogen battery work?
A nickel-hydrogen battery is much like any other battery with stacks of electrodes but held inside a pressurized gas tank. The cathode is made of nickel hydroxide, while the anode is hydrogen. When the battery is charged, the reaction produces hydrogen gas, which is oxidized during the discharging process to form water.
The energy-storing process, which involves the production of highly combustible hydrogen gas and a pressurized tank to contain it, raises doubts. However, the peak pressure inside the tank reaches only five percent of that in a hydrogen fuel cell. Moreover, if the pressure of the gas increases further, it results in the conversion of the gas into water again. READ MORE...
