Exploring the Mysteries of Black Holes: Answers to Your Burning Questions

[NewImage]

I've been watching too much science channel specials on black holes and need a few things cleared up heh

On the TV show they said that a black hole is actually not only eating near by stars and gas but actually consuming space time its self. My question is, if space time is being sucked into it at speeds faster then light, how is the graviton force particle able to escape. Do gravitons move faster then light?

Another question I have is about super-massive black holes. Some black-holes like the ones in the center of galaxies are billions of solar masses while others are only 10. On TV they said that the singularity is infinitely small and infinitely dense but if this is the case is one infinity is bigger then the other one?

Graviton 'waves' propegate at the speed of light. Gravitons themselves, being the force carriers of Gravity are not subject to its effects.

As for the size of black holes, if they are indeed singularities, then they are infinitessimally small points. Anything with this 'lack of dimensional size' but with ANY amount of mass, MUST have infinite density. However, it is the mass that is responsible for their gravitational force, and density is irrelevant. Therefore, a 10M(sun) Black Hole will be weaker than a 1 000 000M(sun) Black Hole.

I don't think that matter or 'spacvetime' is being sucked into Black Holes at speeds greater than light, despite clearly being greatly accelerated. However the pull of gravity can be strong enough to curve any photons' paths by a large amount. Any photons (or matter too) that enter the Event Horizon, even with their immense speed, lack the energy to escape.

Also, I'm not sure on the space-time being sucked into a Black Hole. Einstein concluded that spacetime itself is warped around mass, the magnitude of warping proportional (inverse square of mass to distance of an affected mass) to the mass itself. This warping effectively IS gravity.

It's great that you've been exploring the mysteries of black holes! They are fascinating and complex objects in our universe. Let's address your questions one by one.

Firstly, it is true that black holes consume not only matter, but also space-time itself. This is because their immense gravitational pull is so strong that it warps the fabric of space-time, causing it to collapse in on itself. However, this does not mean that space-time is being sucked into the black hole at speeds faster than light. In fact, nothing can escape a black hole once it crosses its event horizon, including light. The graviton force particle, which is responsible for the force of gravity, is also unable to escape once it enters the black hole's event horizon. This is because the speed of light is the ultimate speed limit in our universe, and nothing can travel faster than it.

As for your second question, it is important to note that the singularity at the center of a black hole is a theoretical concept. We do not fully understand what happens at the singularity, as our current laws of physics break down in such extreme conditions. However, it is believed that the singularity is infinitely small and infinitely dense. This means that it has infinite mass and zero volume. As for the comparison between different black holes, it is not accurate to say that one singularity is larger than the other, as they are both infinitely small. It is more accurate to say that one black hole has a greater mass than the other, but the singularity itself remains infinitely small in both cases.

I hope this helps clarify some of your questions about black holes. Keep exploring and learning about these fascinating objects in our universe!
