Is relativistic velocity a noticeable effect?

Relativity is ridiculous theory.

Fortunately for Einstein's ghost, it's better than the even more ridiculous alternatives!
Relativity convinces people to not make some  useful experiments. Therefore it is less ridiculous but  more dangerous for development. :(

On the contrary, it prevents people from wasting time with ridiculous experiments, thus freeing them up to make scientific progress.  Relativity has been supported by so much experimental and observational evidence that it's definitely a highly accurate model, even if it turns out to only be approximately correct. 

By the way, when experiments are done that seem to rigorously show that relativity might have a problem, they're taken very seriously, as is evident from the recent faster-than-light neutrino result.
You are scientist,therefore you have a right to define that which experiment is ridiculous. But if relativity is completely right,and this experiment will help me understand it, then this experiment is not ridiculous for me. :P

FWIW if you want to see a real world relativistic effect do the following:

1) pick up a magnet

2) stick something to it

The magnetic attraction is due to lorentz contraction and lack of simultaneity of the charges as they go around in a circuit (either around an atom or around an electrical circuit).

Usually, relativistic effects aren't very noticeable, and in an electrical circuit the charges are actually only moving at a few miles per hour, but electrostatic charges have a very, very strong effect, and it multiplies up the relativistic effect.

Let's consider mental experiment:
The planet like our Earth escapes from us  at speed ~ 260,000,000 m/s(Lorentz factor =2).
We see rotation of this planet in 2 times more slowly than rotation of our Earth. This planet  is younger  in 2 times than our Earth. If our Earth receives acceleration till zero speed concerning this far planet then our Earth  is younger in 2 times than this planet. Will the acceleration  transform us into ancient bacteria or transform people of the far planet into people of future? ???
