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...

Electric Propulsion System


The IX-6315 "Dawn" Electric Propulsion System is a tiny-sized engine which runs on electricity and xenon gas propellant. It's modeled after the real-world Hall effect thruster.

This engine has a phenomenal fuel efficiency (4200 s Isp), but very low thrust and requires a substantial amount of electricity to operate. Xenon gas is provided by xenon containers like the PB-X50R Xenon Container, PB-X150 Xenon Container or PB-X750 Xenon Container. Electricity can be obtained using solar panels, radioisotope batteries (RTGs), and fuel cells

Solar panels are recommended in this case, however RTGs are very efficient when traveling to far distances such as Jool and Eeloo. The amount of electricity needed to keep one ion engine running at full thrust is roughly equivalent to half the output of one Gigantor XL Solar Array (however one array will power two engines only near peak sun exposure around Kerbin), 6 Fuel Cells, 12 PB-NUK Radioisotope Thermoelectric Generators, or 25 OX-STAT Photovoltaic Panels at peak outcdput. 

When pairing with solar panels, it is highly recommended to bring more than it needs (slightly less than 9 Ec/s). Not all panels are at peak output during operations, and maximum available power falls of with the square of the distance from the star.

Batteries can be used to store the electricity since there may be times the solar panels will be blocked from the Sun by objects or the dark side of celestial bodies. For extended burns in the darkness the fuel cells happen to be a good choice. When the power is provided by the fuel cells the majority of the mass flow (about 69.2%) is liquid fuel and oxidizer used by the fuel cell. 

Thus the ion engine powered by the fuel cell may be seen as having much more modest but still impressive effective Isp of 1293 sec. However if the burn doesn't take more than a couple of hours the stack of RTGs providing the same amount of power (and thus thrust) tend to be heavier than the fuel cell array and its fuel tank. The RTGs should be reserved for very long low-thrust burns in the deep space.  READ MORE...

SPACE: The Final Frontier

I have been a fan of Star Trek from the very beginning when James T. Kirk, the cowboy, broke whatever rules he needed to in order to WIN whatever it is that he needed to win; and, my interest continued with the very diplomatic and smooth John Luc Picard.

Most Science Fiction Movies are nothing but speculative bullshit and conjecture concerning the way the world was going to evolve and how space exploration was the only viable alternative.

SPACE TRAVEL
ALIENS
ALTERED DNA
ABDUCTIONS
MULTIPLE DIMENSIONS
WORM HOLES
BLACK HOLES
TIME TRAVEL

These are all the areas of interest for those of us that are interested in or believe that there is other life in the Universe besides Human Beings.

Why do we need to know these answers?

Because our entire existence revolves around the Christian Belief that there is a CREATOR who we see and worship as a Father/God.  Interestingly, every single major and minor religion and/or philosophy has a CREATOR as the foundation of its faith.  Some of those religions also believe that there were other gods who were subordinate to the one major God which we, as Christians, might relate to ANGELS, who, according to The BIBLE did much of God's work and/or delivered his messages.

IS THIS SIMPLY A COINCIDENCE?

I don't think so...

Our Universe is curved, so it is entirely possible that the end of this curve merges into the beginning which would be the ultimate singularity that we have all read so much about.  Plus, it is entirely possible that there are multiple dimensions because Jesus said, "in my Father's house there are many rooms."

While some religions as well as philosophies are hard to believe, we all know that there are elements of truth in all religions and that these elements of truth can be found in ancient writing and drawings on cave walls or inside of buildings like the Pyramids.

God, could then be the leader of all Universal People and like the MATRIX all universes end at their beginning and the process is repeated.
