Hello, I have been lately very interested in time dilation. I have found out many information about it and it's very interesting for me. But I have few problems I don't quite understand, so I will be glad for your help.
Let's start:
There's a man traveling in a spaceship from point A to point B.
distance A to B: d=1 light year
speed of spaceship: v=0,99999999999999
The man is 30 years old
So here are the options:
A) on the day of his 30 birthday he start his journey from A to B, with the spacewhip. As soon as he get to the point B, will his age be approx. 31? (mostly I heard this to be the truth. That from his point of view in the spaceship, the time elapses the "normal" speed for him)
B) He will arrive to the point B almost instantly - from his point of view (I don't trust this option much, it's making a mess in what I know about it. And I find this option unlikely to be truth. But also I heard the photons moving v=1c, basicly don't know what time is. Or in other words the time for photons is t=0. And from this the photons should "feel" to be everywhere instantly)
So where's truth? I am not complete "noob", but also not an expert.
I am 99,9% sure that the man will be 31 years old when arriving to B.
But also it seems to me logic that photons moving v=1c don't have time - t=0, and v=1.
