Was Einstein wrong about gravity? Einstein said gravity and acceleration are indistinguishable, and therefore identical.

Is he right about that?

Astrophysicists theorize that near the event horizon of a black hole, physical matter would undergo gravitational "spaghettification".
That means matter would get stretched out; because the exceptionally powerful gravitation would be very strong, but stronger on the portion of the matter closest to the black hole; weakest on the other end.

Thus, the matter would be stretched apart, or at least elongated.

But in acceleration, rather than stretching things out, matter tends to get compressed.

Or phrased another way; gravity has a gradient. Acceleration does not.

So what's the deal Einstein?

A little booboo perhaps?
