Sorry gave up! Text too small and feint to read.I'm really passionate when it comes to that kind of stuff This is my first vid! ^^

Move in an instantaneous way isn't possibile, to do this in fact we would have an infinity speed. The equation of the speed=space/time, in order to reach them points instantaneously force the time to be 0, and the speed to be infinity. The space, with this element wouldn't have any importance and we could reach every point of our universe that we want without problems. But, as I have already sayd, it isn't possible, or at least I don't think that is possible. But I think that for as, people and probe, made out of matter, is possible to reach at least an half of the speed of light, and thanks to the future changement, we can menage to get a lot of new discoveries on this fields, in fact the closest star to us is Proxima Centauri, and with my previousy waether of data we can reach it in seven years, so we can use this in our advantage, isn't the best thing that we can have, but is an interesting beginningUnless we can find a way to make going anywhere in this galaxy instantaneous, I don't see us ever leaving the solar system.
Excuse me if I interfere in your speech, but only the clock of the ship would slow down, so for the Earth and for us the time will rest at the same speed. Thus, during his life the hypothetically astronomer would travel through the space without any problem for 100000 years, isn't important for him, because maybe he would have become old of 80 years (I don't know anythigh about the relative law, and numbers are taken casually). When he will return home, he will find probably an Earth destroied by the passing of time, he will discover to be the last one of the uman race. He won't can communicate his discoveries with us, the time passed here is too much. It would be useless.Also, the traveling across a galaxy like ours that is 100,000 lyrs in diameter will take a very, very short amount of time according to the clocks on their spaceship if they are travelling very, very close to the speed of light. This is easy to calculate using SR (special relativity).

Excuse me, I feel to disagree with you. I think that at the speed of light they ( the hypotetically crew) are aging slower than us on the Earth, in fact I have heard that the time pass slower when the speed is high, here there is a inverse proportion. I can even wrong, I'm not an expert and you have also more experience than me, but I remember this.The clocks will look normal to those next to them, but the clocks that appear, by either party, to be moving will appear to run slower. The space crew will determine those on Earth are aging slower. There is some sort of symmetry break that happens when the ship stops then returns so that the travelers will arrive having aged at the lesser rate. I don’t understand how this happens, but that’s what I’ve been told.
You hold the opinion I once held. The "Twin Paradox" account would support your view as the twin traveling in the spaceship would return younger than the Earth sibling. Although SR (Special Relativity) demonstrates this -- atomic clock "twins" have confirmed this with one returning from space having run slower -- SR is more complicated when you want to talk about what different observers say about the clocks. The space travelers will look at Earth clocks and see them run slower.Excuse me, I feel to disagree with you.

There is something wrong. If the traveller when return on Earth is younger than his twin, we are forced to say that the time ran faster on Earth. If the time on Earth had run slower as you said, the traveller would have returned elder than his twin, and for this reason I disagreed (and now too) with you.

At first I thought that the space travelers had to see the Earth clocks run slower simply because the light from the clocks took more and more time to reach the ship, but this time lag won't be enough to account for the actual time observed. I wish I understood it better, but I don't.

You're on the right trail but you have a ways to go, IMO.There is something wrong. If the traveller when return on Earth is younger than his twin, we are forced to say that the time ran faster on Earth.

Now I understand,though it is very complicate as to explain as to understand. I also understand why it is called paradox and I get along with who decide to call it so. I understand thanks to this part and also in the part in which you wrote of deceleration of the ship when it is going to return home. Thank you!Namely, that relativity means that the spaceship could be regarded as still and the Earth is moving away from them. Hence they would determine that people on Earth would be aging slower, at least up to the point the spaceship began its deceleration upon arrival to proxima Centauri, or wherever.
Thank you for that video.

Hey this looks like fun! I'd be willing to team up. I am figuring out how to render stuff.Sadly no, but I'd love to learn how to do that. I downloaded multiple animations that are not copyrighted !
Uh!!! That was your first video! I'm a little speechless... it was beautiful...I'm really passionate when it comes to that kind of stuff This is my first vid! ^^

Yeah, that's my question, too. Do you create 3D animations? Thanks.Np though it looks like you are partially right, as the speed without the influence of the planets, the winner would still be Helios 1 and 2.
Keep up the good work (keep making and improving on your videos).
I meant to ask, did you do any of the video physics animations yourself, or you just kind of pieced it together from other sources?
I should've read more of the thread before asking... sorry.Sadly no, but I'd love to learn how to do that. I downloaded multiple animations that are not copyrighted !
Here's my two cents on time... it's standing still and we're passing through it, and it's a man-made construct to account for aging. My perspective is based on statements of how we "look back on time." Seems to me it'd be fixed. If we say, "Remember when...?," then aren't we actually looking backwards at a fixed point to recall that story? Just a thought.I'd say that if we have the technology to build a light-speed spacecraft, we would probably have the technology to detect and stop in time. Surely we are not the only life in the universe and if we are, it means we won against all odds, that we are the firsts. That is scary but also exciting.
Right... no time-travel and no changing the past.TI, "If we say, "Remember when...?," then aren't we actually looking backwards at a fixed point to recall that story?"
This is effectively the BLOCK theory, which I have described elsewhere., I am just describing it. OK!
Briefly, space-time exists as a BLOCK (so the model goes) and contains the past and the future, as well as every NOW moment between life and death, or formation and destruction in the case of objects. This is termed a world line or similar. All NOWs are "real".
A person (or anything) exists as a world line. Because we are not equipped, or have not yet evolved, an ability to comprehend an entire world line, we have invented (or evolved) a travelling NOW which defines the "present". We may be able to revisit your fixed point in the story, but only as a memory. It is not time travel, and we would not be able to interfere with the past. There are slight variations to the model, but that is the general idea. For example, dreams may be involved, perhaps as ways of avoiding the limitation of comprehending the world line we travel. Again, I am not subscribing to any particular model.

P.S. The BLOCK model has an apparent problem, in that it does seem to require predetermination.
Maybe this is dependent on our misunderstanding of the nature of the travelling NOW mechanism.
Predetermination would also contribute to 'loneliness' in that it might be associated with inability to change our futures.
Okay, all good here. I will have to look for it a little later and a.s.a.p.The Interactor
I don't want to lead this thread off topic , so I will start a new one called "The Block Model" - for and against". I hope to encounter you there . . . . . . . .
Eeeeeeeeeeeeeeek! I already have = The Block Universe model, here in Cosmology.
Hope to see you there!
