“Was Einstein wrong?” It’s a terrible question. We know general relativity can’t be the ultimate theory, because gravity and quantum mechanics do not play well together. The other forces of nature (electromagnetism and the nuclear forces) all fit quite well into the Standard Model of particle physics. But gravity isn’t part of that and we don’t know how to tie it in, although string theory might help. Extreme systems such as the centres of black holes and the first moments of the Universe might also require more explanation than general relativity can provide.So probably, someday, a theory will be touted as a replacement for general relativity – one that fixes all the problems left lying at the edges. But that won’t mean Einstein was wrong; in the same way that Newton was not proved wrong by Einstein.
It doesn’t matter whether Einstein was right - it matters whether his theory is useful. You only need to look at your GPS device to see that it is.
