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

In summary, the conversation revolves around the question of whether the mass and gravity of an object become infinite as it approaches the speed of light. It is clarified that objects with mass cannot actually reach the speed of light, so their mass never becomes infinite. It is also explained that the gravity of a black hole is not truly infinite, but rather strong enough to prevent anything from escaping due to its high escape velocity.

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.
 

What is the relationship between the sun and black holes?

The sun and black holes are both massive objects that exert gravitational force. However, the sun is a star made up of gas and plasma, while black holes are collapsed stars with a singularity at the center.

Does the mass of a black hole affect its gravitational pull?

Yes, the mass of a black hole directly affects its gravitational pull. The larger the mass of the black hole, the stronger its gravitational pull will be. This is why black holes are known for their extreme gravitational force.

How does gravity play a role in the formation of black holes?

Gravity is the driving force behind the formation of black holes. When a massive star dies and collapses, its gravity becomes so strong that it pulls all of its mass into a single point, creating a singularity. This singularity has such a strong gravitational pull that even light cannot escape, resulting in a black hole.

Is there a limit to how massive a black hole can be?

There is currently no known limit to how massive a black hole can be. However, the theoretical upper limit is around 50 billion times the mass of our sun. Any black hole with a mass higher than this is considered a supermassive black hole, which are found at the center of most galaxies.

How is the mass of a black hole measured?

The mass of a black hole is measured by studying the orbit of objects around it. The strength of the gravitational pull of the black hole can be calculated by observing the orbital velocity of objects around it. This allows scientists to estimate the mass of the black hole using the laws of gravity.
