Does a body approaching toward you exhibit time dilation or timecontraction?

I can imagine the twin paradox resolved if the travelling
twin undergoes time dilation when he is receding, but
he undergoes time contraction when he is returning home.
So, at the end of the trip, he will stay at rest near his twin,
and they would have aged equally.

We need clocks that can look out of the window and see which direction
and towards which destination are travelling.

Are you a troll Albertito?

Alberth****o,

Time dilation is a function of v^2.
Twins paradox is explained as a function of trajectory thru
spacetime , thelonger the trajectory, the shorter the elapsed time,

"Imagination" is useless -- I can IMAGINE the cow jumping over the moon.

What science requires is understanding the theory and then CALCULATING
what happens. Do this for SR and the twin scenario, and one obtains
agreement with experiments. Nothing more can be expected of a theory.

No, I'm not a troll, believe me.
No, we do not need that feature for clocks.
It suffices all the clocks had a universal origin
and were synchronized, say a "Big bang"
origin.

I don't agree. Einstein was overly imaginative

Now look at how Pentcho Valev when he first came here
was wiped the floor with when he had conceived the same
thing. He called it "time constriction" though. He learned
nothing since then.
Note that Pentcho Valev is a real imbecile, so just imagine
what you must be then.

His imagination was guided by experimental evidence, not just flopping
around like yours. And he became famous because he turned his imaginings
into a real theory in which he CALCULATED things. Had he not done that,
he would not be remembered.

My imagination is not flopping around. I know
very well Einstein's relativity is not the ultimate
theory. The problem is the people that worship it,
not the theory itself. Worshippers are the only
serious obstacle for the advance of science.
Worshipping is closing your eyes, and trying to
refute anything that sounds heretic.

And he became famous because he turned his imaginings

What the hell is a "real theory"? I thought all tneories,
once they exist, are real. What do you mean by a
"real theory"? Are there theories more real than others?

Why are you so sure time contraction is not a real
phenomenon? Because Einstein said that's impossible?
Can you please tell at what rate a clock is running
in a distant galaxy wrt your clock?
