Така е.

Но за да има забележим ефект, този дето е пътувал, трябва да го е
правил със скорост, която не е пренебрежимо малка спрямо
светлинната.

Обяснения ?



Спецялната теория на относителността:
http://en.wikipedia.org/wiki/Special_relativity
Това там не е обяснено.
там требе да цвъкнеш на това:
http://en.wikipedia.org/wiki/Time_dilation
Това определено не обяснява парадокса, т.е. че брата-космонавт би се
окажал по-млад, когато отново се срещне с брат си на Земята.


Напротив, даже го казва в прав текст:

"Time dilation would make it possible for passengers in a fast-moving
vehicle to travel further into the future while aging very little, in
that their great speed retards the rate of passage of on-board time.
That is, the ship's clock (and according to relativity, any human
traveling with it) shows less elapsed time than the clocks of observers
on Earth. For sufficiently high speeds the effect is dramatic."

Това не адресира проблема със срешата им _след_завръшането_ на космонавта,
липсва нещо съществено.

Ми хайде де, обясни ни на неразбралите /какво/ липсва и не сме разбрали.
