Relativity revisited once more still again

The evidence is actually all around us, within us, and present in every decision we make.

Thanks once more Que. However, wonder what's meant by "The evidence." If the hologram is evidence of the possibility that the Universe could be a hologram, well, okay. However if evidence that it really is, I'd say sheerest nonsense

I can only show you the door.

1: Deceleration is just a form of acceleration. So the person who decelerates is the one who has time slow down for them.

I'm still thinking about this, Ora. I decelerated in order to come to a standstill with the rest of the Universe; yet when we meet again I'm very old and you're very young; so wasn't it you whose time had "slowed down"

Relativity is stupid, illogial and weird!

Though the relativistic effects upon a moving object hold up mathematically and have repeatedly been verified, they do indeed seem strange. I've yet encountered no revelation explaining them in plain language intended for your Average Clod (me)

Have you studied relativity?

I'm still thinking about this, Ora. I decelerated in order to come to a standstill with the rest of the Universe; yet when we meet again I'm very old and you're very young;

No. You would be the one who was very young. I would be the one who was very old.

In your experiment, the person who decelerates is the one who has time slow down for them.

I'ver perused two or three books and have to admit there seem a few loose ends but nothing even suggesting it's dead wrong

Maybe reading wrong tomes

But repeating my general q, can anyone explain not "scientifically" or "mathematically" but to the satisfaction of everyday logic and the intuition how these relativistic effects happen at this arbitrary speed c

No. You would be the one who was very young. I would be the one who was very old.

Perhaps Ora you perhaps misunderstood my experiment. You and I are the same age, taking off eg from nearby planets opposite Earth. When I reach home I decelerate, remaining at the same age of course. But you keep going, thus without apparently aging. Presumably when you've circumnavigated the Universe without running into anything you are still the same youth as we were at departure whereas I am very old

This is pretty much wrong. Here would be a similar, but correct, description. We have three people, A, who is on the Earth and B and C who are on a planet circling the star Sirius, 8.6 light years away. At the start of the experiment, all three people are 20 years old. Now, B and C leave Sirius. Both travel to Earth, but B by a straight path and C by a long, indirect path. Both B and C quick accelerate up to about 99.999% the speed of light. Their bodies can only tolerate just so much acceleration (or deceleration), but let's ignore this. B arrives on Earth having aged only slightly (I'm too lazy to calculate how much). From his point of view, his trip took a very short time and he is still 20 years old. He finds that A is now 8.6 or so years older, so 28 or 29. C, who travels a total distance of 15 light years because he took the scenic route also feels that his trip has taken less than a year, but he arrives on Earth to find A about 35 and B about 26 or 27. You should read a book about special relativity, rather than trying to get the facts from a message board. You've been doing this for a year and still seem to lack a basic understanding. Get a book.

Perhaps owing to the curvature of space

Please explain how the hell space can curve???
