Small laser ring interferometer 

Здравствуйте. Благодарю за интересное видео. Мы как слепые котята; чёрные дыры, тёмная материя, тёмная энергия. А что если мы на все это посмотрим через простой новый эксперимент с гравитацией. «Взять на поверхности, земли гравитационное поле и им размазывать направлено скорость света» в оптических гироскопах которые несут по окружности, на специальной платформе без угловой скорости. (Типа опыт Майкельсона по обнаружении эфира; оптический опыт Саньяка вращающийся диск; мысленный опыт Эйнштейна с диском - все это в одном эксперименте)

Very cool demonstration (no pun intended)! I like how your breath reveals the laser beam.

It is the Sagnac formula that is to prove the Ether theory right. Which "happens to be " the same as the relativistic formula, as long as the relativistic formula is only a crafty copy / paste of the Sagnac formula. They both measure c + v on an infinitely large circular path, which math says that is to be seen as a straight line.

Special Relativity still holds based on a mathematical prank . The relativistic dummy copy of the Sagnac formula is a shameless make up. It is the same v = Rw formula used by Sagnac, yet written in a funky way, such as to induce the illusion that it is relativistic.The only relativistic "contribution" is the Minkowsky ct^2 = ct^2 1 = 1 start. Crucially, the c + v (as measured by a relativistic stationary observer !) is artificially implanted through the back door, without any theoretical justification. The cheap clownery is eventually useless, because if you chose R tends to infinity, you measure c + v in a straight line.
