How do we see a black hole if light Cannot escape?

In this way, light can be emitted from a glowing gas cloud just outside of a black hole even though the black hole itself emits no light. Therefore, we can indirectly “see” a black hole by seeing the glowing gas cloud that surrounds it. This gas cloud is called an accretion disk.

What type of light can escape a black hole?

No light of any kind, including X-rays, can escape from inside the event horizon of a black hole, the region beyond which there is no return. NASA’s telescopes that study black holes are looking at the surrounding environments of the black holes, where there is material very close to the event horizon.

What if a black hole and a white hole collide?

The mass the white hole is expelling is also being turned into energy for the black hole. So if a white hole and black hole collided, we’d have a massive black hole roaming around the Universe, destroying everything in its path.

Are stars white holes?

Black holes are created when stars, much more massive than our Sun, die catastrophically in a supernova. White holes are created when astrophysicists mathematically explore the environment around black holes, but pretend there’s no mass within the event horizon.

Can nothing escape a black hole?

Answer: Within the event horizon of a black hole space is curved to the point where all paths that light might take to exit the event horizon point back inside the event horizon. Since nothing can travel faster than the speed of light, nothing escapes the event horizon of a black hole.

Is there a white hole in space?

White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes. While a black hole’s event horizon is a sphere of no return, a white hole’s event horizon is a boundary of no admission — space-time’s most exclusive club.
