Then a fellow ATS member made the following claim
I need to leave now. Tomorrow we can talk more about this. For now, just think about this: you are born to explore other planets. Actually, the time will come in which you will need to leave your planet. For that trip, you must have had already selected a target viable exoplanet. By the time you are called to leave your planet, you would have acquired the knowledge to travel at near the speed of light.
In fact, if you don't, you are dead.
Going to an exoplanet is a one-way trip. No return. Therefore, if you go, you go to stay. At any cost. At any rate.
And what you'll do... is what they are doing. Logic is logic.
Finally, 500 years Earth time is just 7 years spacetime, at the speed of light. Events that you think happened in 1950, happened 3 months ago, from the point of view of someone approaching you at near c.
I wouldn't dismiss RV as a viable sounding technology. Actually, is the only one you have. Inside your brain.
numbers were not all that off the mark within the context of the theory of relativity, and using the time dilation formula.
Problem is that no object with mass can go the speed of light, so we have to use some number less than 3.0 X 10^8. So we used 2.999 X 10^8 and arrived at something in the neighborhood of 50 years.
7 X 50 = 350 years. For all I know, it is 500 years at 3.0 X 10^8, because even the tiniest fractional increase as we approach the speed of light causes a mind blowing increase in the dilation of time. We begged out at 50 years.

Is there any truth to these claims, if not how are they wrong? Thanks in advance.

Not sure I am smarter than you but the so-called planets are really stars. There is no outer space, only heaven, and the stars revolve around us. Yes, you are significant, not what the pseudo scientists would have you believe. Hope this helps.
The question has insufficient information to answer, specifically the distance to the exoplanet. If it's 6 light years away and it takes you about 2 years to get there then your friend would probably still be alive.

The math in this is weird. So in essence if I wanted to visit a friend and to do so I have to travel to an exoplanet. Assuming I were to have a ship able to reach near light speed, Also assuming I had to travel at near light speed for atleast 2 years to reach destination said planet.
Are you saying that said friend, a human with the exact same lifespan as me would've already perished by the time I arrive there?
And/or I would because im traveling at light speed somehow survive many years longer than my friend, another human with the exact same lifespan would?
That claim is based on a mis-application of E=mc² where it doesn't apply. Mass doesn't increase, Einstein said so. What increases is momentum and energy, according to Einstein, not mass.

Note also that your effective mass increases the faster you travel and thus the energy required to accelerate even faster nearer and nearer to light speed becomes exponential approaching infinite to get to light speed.
