I think that it would not be actually possible to see them as they both would have 0 size to any third observer. But I am not sure that the rule is exactly such, and if we ignore that I would say that to any third observer both travellers would seem to be completely halted. So a third observer...
I guess this is my last theme here with this nick and from this IP:) But I just love the answer that came to my mind (maybe it is posted somewhere here, but I could not find it).
1) Our reality:
If the thing traveling would have the brain operating the same way as our brain (or any other...
As far as I understand experiments were the things that brought this up actually. During experiments it was noticed that no matter how fast you chase the light it gets away from you with the same speed in all directions. So depending on the speed your world view changes. If you would shoot two...
I think I myself now can answer the question (i.e., how the world that Earth man sees looks to rocket man at that moment).
The Earth man should wait for half the second for the image of the rocket man to arrive, then check what rocket man's clock shows in that image and then remember how the...
Ok, sorry KEN G, I thought you meant that Anony-mouse statement that "The image Dude A is seeing of Dude B's calendar has sped up" is wrong. And that my one statement really is misleading. I agree that the image will be sped up but calculations will show that time goes slower.
Sorry...
Matheinste - actually there was a mistake in the idea of the very last sentence of that post, but not to go into an off-topic and as I guess I have been spamming here too much I won't go into details. Your comment was correct. (that does not change the validity of what I said to Anony-mouse in...
Anony-mouse: sorry again - discard completely my previous post. I just noticed you were talking about 6 A's months.
So during those 6 months all the time he really would have observed B's time running faster.
As soon as B started the trip, distance between the planets became shorter for him.
Anony-mouse: sorry about the start date, I somehow misunderstood that B started off on 01/01/2008. So for your situation I would say that it would be the following way:
1) A on 01/01/2008 sees B leaving his planet on 01/01/2007.
2) A sees B traveling towards A. B's clock seems to be running...
So - anony-mouse: once B turns the callendar to 01/07/2008 and looks at A he will see that he has almost reached him and that during the last 6 months somehow he has reached, e.g., 06/01/2009 (when B started the trip he saw A celebrating 01/01/2007). And what B will see A doing? He will see A...
No, Ken G, I would disagree that during B's trip both would see slowed down images. It's exactly the opposite. It's quite directly explained in the twin paradox.
As soon as B starts the trip (01/01/2008) he starts seeing A's time running faster. B still sees the 01/01/2007 when he looks into...
I will talk only about that distant star and 10 years. So - photon would think that no time has passed.
You measure time and distance so that a photon gets away from you 300 000 000 meters per second. If you start chasing the photon from the distant star very fast, and after your observations...
Thanks for the replies!
In the first situation with beam B only I was talking about the predicted positions. Let's discard this completely.
In the second situation I was talking about the detected situation on Earth and what would the Earth man think should be the detected situation for...
I am sure this question in some form gets posted here all the time again and again, but I somehow can not find it in the form I would recognize, so my appologies for probably posting it again.
So one of the classics: Two light beams - A and B get launched from Earth to the opposite directions...
