Black Holes & Time: A Collision of Forces

While the gravity of two black holes can affect each other during a collision, it is not strong enough to bend space and cause a region to go back in time. In summary, during a collision of two black holes, their gravity can overlap but it is not strong enough to cause a region of space to go back in time.

I was just reading upon black holes, collision and how it bends space and time..
I know for a fact that time stops after the event horizon, but during the collision of two black holes, can the gravity 'overlap' between them to make it strong enough to bend space which in result be enough to have the region of space go back in time? (sorry if it doesn't really make sense)

No, you don't know that for a fact, since it's not true.

No.
 

FAQ: Black Holes & Time: A Collision of Forces

What is a black hole?

A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape. It is formed when a massive star collapses under its own gravity.

How do black holes affect time?

Black holes have a strong gravitational pull that bends space-time. This means that time moves slower near a black hole compared to areas with less gravity. This phenomenon is known as time dilation.

Can anything escape from a black hole?

According to our current understanding of physics, nothing can escape from a black hole once it has passed the event horizon (the point of no return). However, some theories suggest that information may be able to escape in the form of Hawking radiation.

Can black holes collide?

Yes, black holes can collide with each other. When two black holes merge, it creates a larger black hole with a stronger gravitational pull.

What happens when someone enters a black hole?

It is currently unknown what exactly would happen if someone were to enter a black hole. However, it is believed that the strong gravitational pull would cause the person to be stretched and eventually torn apart, a process known as spaghettification. The person's information may also be lost within the black hole.
