In simple terms, once something gets within a certain distance, gravity is so strong that it is impossible to escape, even moving at the speed of light.

Is a black hole visible?

For most purposes, no, black holes themselves are not visible. Black holes absorb everything near them, including light. Light needs to originate from an object or strike an object and reflect from it and to your eyes in order for you to see it. Light that enters a black hole can never leave. Since black holes do not emit light or any form of electromagnetic radiation, it is impossible for astronomers to observe them directly. However, matter falling into a black hole can become superheated and emit light and x-rays before falling past the point from which nothing can return. We can detect this radiation. Theoretically, you could also see the event horizon of a black hole if you got close enough; it would appear as a completely black sphere against a background of stars. The light from stars behind the black hole would be highly distorted, as can be seen in the image above.


What colur is the black hole?

They are black. This is because the are merely dense balls of matter from which light can not escape. Though there is a unproved process called that goes by the name of hawking radiation that leads to electromagnetic radiation(light) being emmited from black holes. See do black holes die for more details.


Why can black holes not be seen?

You can never see a black hole. Never. This is because the gravitational pull of the black hole is so strong that nothing, not even light can escape from it, therefore the light from a black hole would not be able to reach your eyes.What you would see is a big black patch of distorted light in the middle of space.


Is a white hole just as dangerous as a black hole?

White holes are theoretical objects that are the opposite of black holes, expelling matter instead of absorbing it. They are not considered to be dangerous like black holes, as they do not have the same gravitational pull or ability to trap objects with their intense gravitational force. White holes are not thought to exist in our universe.


What does a black hole do to space and time?

Per Einstein's General Theory, which is the theory of gravitation, gravity affects space itself. A black hole (or any mass) by way of analogy is like a weight on a rubber sheet which stretches the sheet; in this sense a black hole is shown to 'stretch' space to an extreme curvature or gradient which is effectively infinite. Rotating black holes are also calculated to evidence a phenomenon called frame-dragging, in which the space itself around them in spinning in the same direction as that of the black hole.

What is the story behind the Black hole?

a black hole cannot be ovserved, so it could not be discovered. a black hole is created when an extremely old star implodes on itself causing a distortion in space, making a hole with suction power so strong it can even trap light.


What happens when something escapes a black hole?

When something escapes a black hole, it means that it has managed to overcome the intense gravitational pull of the black hole and move away from it. This is a rare and complex event, as black holes are known for their strong gravitational force that can trap even light.


Is trap hole a targetting card?

Yes, Trap Hole targets the monster you use it against.


What is the size of a black hole and how does it affect its gravitational pull?

The size of a black hole is determined by its mass, with smaller black holes having a smaller size. The gravitational pull of a black hole is incredibly strong due to its mass being concentrated in a very small space, creating a powerful gravitational force that can even trap light.


If I synchro summon a monster can my opponent activate Trap Hole on it?

Synchro summoned is considered a special summon so Trap Hole won't have an effect on them. But try Bottomless Trap Hole or Torrential Tribute instead.

In Yugioh if I summon prime material dragon and someone uses trap hole can I use prime material dragon's 2nd effect to stop trap hole or would it not work because trap hole is chained to the summon?

Trap Hole is not being 'chained to' the summon. Summons cannot be chained to. What is happening is that Prime Material Dragon is being successfully summoned (ie, not negated) then Trap Hole is being used in response. Because of that, it is perfectly fine for Prime Material Dragon to chain his effect to Trap Hole.


Which is better - Trap Hole or Bottomless Trap Hole?

It depends on the circumstances. Generally, "Bottomless Trap Hole" will be the better card; it works on Special Summons and it removes the monster it destroys from play. However, "Trap Hole" has one advantage: the monster summoned only needs 1000 ATK to trigger it, whereas "Bottomless Trap Hole" requires at least 1500 ATK. So, it would depend upon the type of deck you planned to use or went up against, but most people would choose "Bottomless Trap Hole".
