Relation between the sol, mass, gravity, and black holes

Click For Summary
SUMMARY

The discussion centers on the relationship between mass, gravity, and black holes, specifically addressing the misconception that mass and gravity become infinite as objects approach the speed of light. It is established that while the mass of an object increases as it nears light speed, it does not reach infinity, and thus gravity does not become infinite either. The escape velocity of black holes exceeds the speed of light, which prevents anything from escaping, but this does not equate to infinite gravity within the black hole itself.

I'm a fan. Not a physicist or astronomer.. But this question is bothering me. If the mass of an object increases to infinity as it approaches the speed of light, does that also create infinite gravity at the object?

And if so, if we consider the gas swirling around the black hole is very near the speed of light, wouldn't the mass of the gas be infinite? And therefore the gravity of the gas would be infinite. So. Does the inside of the black hole have infinite gravity or does just appear so because the gas at the edge has infinite gravity?

Near the speed of light is not the same as at the speed of light. Since all objects with mass cannot go at the speed of light, their masses never become infinite.

Black hole gravity is not infinite. It is large enough so that the escape velocity is greater than the speed of light, so nothing can escape.
