Our understanding of physics and its mathematical foundations break down - they make no sense at all - in the realms of the very large and very fast. In mathematical terms, the density of matter in a black hole becomes infinite, and we cannot interpret what that means. We call this, the place where our mathematics breaks down, a "singularity". At a vaguely-knowable distance of the singularity, our math once again makes sense, and this distance is called the "event horizon".
The size of the event horizon - the limits of what we can know and observe - is related to the mass of the black hole.

Does a neutron star have an event horizon?
No. Only black holes have event horizons.
Does a giant star have an event horizon?
No. An event horizon is an area where even light cant escape so only black holes have it
How does the term spaghettification relate to black holes?
They hypothesize that that is what happens when you enter the field of the event horizon.
Do black holes expand or collapse?
The general tendency is for black holes to grow. If any matter falls into a black hole, its mass will increase, and therefore its Schwarzschild radius (the radius of its event horizon) will increase as well.The general tendency is for black holes to grow.

Can you watch objects being pulled past the event horizon of a black hole?
No. Nothing, not even light can escape from within the event horizon. Since light can't get out, we can't see anything inside, which is why black holes are black.
Make a sentence with the word horizon?
The horizon was beautiful. Black holes have an event horizon.
Does a neutron star have an event horizon?
No. Only black holes have event horizons.
How are black holes measured in size?
By the diameter of their event horizon.
Could black holes be time warps?
Black holes do distort time. The closer you get to the event horizon of a black hole, the slower time goes. From the perspective of someone outside, time at the event horizon stops.
Does a giant star have an event horizon?
No. An event horizon is an area where even light cant escape so only black holes have it
How can an event horizon of a black hole generate X-rays?
It doesn't. The X-rays we detect from black holes are generated by superheated matter before it crosses the event horizon.
What is happening at the event horizon if two black holes meet?
The question is so ill-defined as to be meaningless. Nothing in particular is "happening at the event horizon".
Why dont stars get sucked into black holes?
Stars do get sucked into a black hole if they pass the event horizon.
Are black holes the size of stars?
Except for supemassive black holes, no. Most black holes have about the same mass as a star, but the event horizon is only a few miles across.
How much do black holes slow time down?
The degree to which time slows depends on the distance to the event horizon. From an outside perspective, time at the event horizon stops.
How does the term spaghettification relate to black holes?
They hypothesize that that is what happens when you enter the field of the event horizon.
What are the black holes called?
black holes The black hole we see is the Event Horizon. Its realy not a hole. Just a spherical region in space where matter ceases to exist.
