Gibberish.

The gibbering, ’nym-shifting troll still does not know the difference 
between “consistent” and “correct”.

Relativity is not an invention.

Instead, general relativity (1915) suggested to Lemaître in 1927 that it 
could be a correct description of reality even in an expanding universe, and 
Hubble showed the expansion of our universe in 1929 as a side-effect of his 
astronomical observations.

Relativity as it is commonly understood nowadays includes two theories, the 
special theory of relativity (special relativity, less commonly abbreviated 
“SR”), and the general theory of relativity (general relativity, commonly 
abbreviated “GR”).

Theories are not considered “valid” at any point in their existence.  The 
’nym-shifting troll still has not understood that theories come along with 
uncertainties.  However, those theories have been experimentally confirmed 
many times.  No modern device would work if they were fundamentally flawed 
as no microchip would work as designed then.

Once again, gravity waves are not gravitational waves.

Gravity waves can be observed daily on Terra with the naked eye, in the 
oceans and the clouds.

Gravitational waves have been detected by LIGO recently with a statistical 
significance of 2σ, i.e. a probability of 95.4499736 %.  Future detections 
by LIGO and similar experiments on Terra and in outer space are expected.

The one who has misunderstood everything is, once again, only the ’nym-
shifting troll.

Rather vomited into science newsgroups by nobody but the ’nym-shifting 
troll.

Not even wrong.
