I found two opinions cited in an old work that I have recently read which I thought would be worth reproducing if only to point out that not everyone in physics generally agreed with Einstein till the 1950s and 1960s. As well as to remind people in general of them as much old work is forgotten unjustly (although sometimes justly) and it is worth remembering it even if it is incorrect.
They are as follows:
‘Einstein interprets an identical equation, derived by some unknown mathematical process, as indicating and establishing a ‘new’ law of gravitation and the existence of a fourth and even a fifth dimension! But, in making this interpretation, he completely overlooks, or forgets his fundamental assumption in regard to time and time units. He overlooks the fact that his variable, hypothetical relativity time, the time to which his equation applies, differs from the ordinary time of astronomy., and that a century of mystic Mercurial time will not be 100 years of earthly time.
Now in support of his theory of variable time, Einstein has cited certain definite observations of physics and of astronomy, and has asserted that, on account of these observations, we ‘must’ accept the theory, no matter how it may conflict with our ordinary common-sense ideas.
The supposed astronomical proof of the theory, as cited and claimed by Einstein, do not exist.’ (1)

‘Einstein is neither astronomer, mathematician nor physicist. He is a confusionist. The Einstein theory if a fallacy. It is based on a glaring error of which Einstein is aware but which he refuses to recognize…. The Einstein theory that the ether does not exist, and that gravity is not a force but a property of space can only be described as a crazy vagary, a disgrace to our age.’ (2)
