@Metal-Brain saidContinue proving you know nothing about Relativity.
It takes the same amount of time to get there no matter how fast you travel. If it takes you 40 years to get here from Alpha Centauri at 1/10 of c that is how long it will take to get here. That is a fact.
Time passage for the high velocity traveler is irrelevant. You cannot make the trip and get here any faster. If you want to argue that high velocity travelers seem ...[text shortened]... to get all of the energy to travel in such a high velocity? And can you survive length contraction?
@Metal-Brain
So one twin is in a spacecraft so close to c there is a 100 to 1 time dilation. Now tell me how much older the twin in the spacecraft is traveling 100 light years.
@sonhouse saidIt does not matter. Time dilation does not get him there any faster.

@sonhouse saidHigh velocity travelers will experience a different passage of time, but anyone who is not traveling at high velocity waits for them for the same amount of time. It is largely irrelevant though, because nobody can travel anywhere near the speed of light. It is simply impossible. It would require too much energy.
@Metal-Brain
You REALLY need to take physics for dummies 101.
For the travelers they effectively go faster than light because their clocks go down on every atom and quark in the spacecraft and their bodies and the food and air and they are still alive after a 100 light year trip and only one year older in my example.
That doesn't change the fact that here on Earth, if you ...[text shortened]... ar forever for you to feel spaghetification, being stretched out like the ancient two horse torture.
@sonhouse saidNot for the observer who is not a high velocity traveler. The speedy traveler takes the same amount of time to return to earth from another star system. That is also a mere thought experiment. Nobody can travel that fast. It is impossible which is a good thing since you would die going that speed.

@Metal-Brain
Funny they used to say the same about flying in the air, that high speed would kill you.
The fact is we have to take into account the changing flow of time in a lot of aspects of our life like making sure GPS works like it should because a change of time flow can disrupt the accuracy of GPS signals so we have to compensate for that which we do but before Einstein we would not have known how to make GPS work at all.
Then there is the science of particle accelerators, which has to account for the change in mass as a particle gets close to the speed of light and the change in time flow of those particles which effects decay times and the like.
We have to know about time dilation when we study cosmic rays because a particle going near the speed of light lives longer instead of decaying and if time flow did not change due to velocity or mass we would think a particle with a known decay time would when hitting the top of the atmosphere should be gone before it ever gets close to ground but that does not happen as it turns out because a particle with mass going close to the speed of light lives longer and takes longer from our POV and therefore can actually reach ground level so we need to understand that to understand the incoming particles.
And if we figure out how to survive going 99.9% of c they WOULD think they are going faster than light even though WE see them going 99.9% of c and they would arrive at the destination a lot younger than a similar twin on Earth. That is not theory that is fact.
@Metal-Brain
I already told you the traveler has a different time flow than someone on Earth, so stop harping on that, we ALL know if you could track a spacecraft going 99.9% of c it would take some 4 or 5 years to get to Alpha Centauri even if the folks on board say it took a month and are years younger than a twin on Earth.
So WHOPPIE DOO DOO.
@sonhouse saidWhat good is it if you cannot survive the high velocity?

@sonhouse saidHe will still arrive to earth at the same time as everyone else on earth expects him to. The passage of time only seems slower to the high velocity traveler. He does not get there any faster. His arrival time is the same to anyone waiting for him on earth, including his twin.

That is merely a thought experiment though. You should take that about as literally as the equivalence principal. Light cannot accelerate.
@Metal-Brain
I'll let the future scientists and engineers deal with that.
It is your OPINION we can't survive high velocity not reality.
Even I can see if you project a sufficiently strong magnetic field coupled with powerful laser to shatter stones and such and be ionized, the magnetic field would deflect such incoming around the craft.
But you have such a limited imagination you can't even visualize what I am saying much less understand it.
@sonhouse saidIt is not.
@Metal-Brain
If c is the limit why is the universe expanding faster than the speed of light?
@Metal-Brain
Show me your paper you must have written proving the universe is expanding less than c.
Scientific data shows in one million years the universe expands 1.4 million light years, a lot faster than the speed of light. 260,738 miles per second, c is 186242 miles per second. At that rate we would get to Alpha Centauri in 3 years not 4.3 years going the speed of light.

@sonhouse saidNo, it appears to be expanding faster than light. That does not mean it actually is.

If the universe expanded from a single point in the universe close to the speed of light you cannot see the whole universe unless you are at the center of the universe. If you are at either side of the edge of the universe you will never see the opposite edge. That does not prove the universe is expanding faster than c.
We cannot see the entire universe, but that does not prove the universe expanded faster than c. All that shows is that we are not at the center of the universe. Now you have to prove there is no center of the universe to prove me wrong.
