It's a perfectly fine limiting case of G + Λg = 8πT. A minor point: it's "the Newton equation" or "Newton's equation", but not "the Newton's equation" (in the same way that one could write &

Systems like the bullet cluster ( https://en.wikipedia.org/wiki/Bullet_Cluster ) are taken as evidence that most of the matter in large-scale, gravitationally bound astrophysical systems does not behave like luminous mat

A contravariant object transforms like a vector. A covariant object transforms like the gradient of a scalar.

We have no experimental evidence that the calculations for gravitational Hawking radiation (or their physical interpretation) are valid. The notion that dumb holes exhibit all the same properties as black holes is conjectural.

120 years ago, people thought that experimental results on wave propagation in continuous media could be used to make statements about wave propagation in electrodynamics. That's how we ended up with ether theories, which were eventual
