Einstein stood the test of time well for a while, but it’s falling apart now.
The problem is that gravity isn’t the predominant force in the universe - electromagnetism is. Advances in plasma cosmology are coming up with much better answers to key questions than absurdities like black holes and neutron stars.
The universe is not gravitic - it is electric. Halton Arp is not given a fraction of his due.
Thank you for chiming in on that point.
I’ll check it out.
