Black holes for dummies

A black hole is where gravity has become so strong that nothing around it can escape not even light. Around a black hole there is a position of no return called the event horizon.

Sometimes even the best watches run slow.

Black holes for dummies. A Black Hole is an object for which nothing can get a high enough escape velocity to get away from it. Think of a cannonball being fired straight up in the air. As it goes up it will be slowed down by gravity and come crashing back down.

If the speed is high enough however it will keep going until it escapes the gravitational pull. These black holes arise from the death of stars when they run out of nuclear fuel. However not every dying star will become a black hole.

The greater the mass of the star the greater the effect of gravity and the greater the collapse of the remaining object. At the center of most galaxies is one of the strangest and deadliest things in the universe. Most black holes regardless of their size are born when a giant star runs out of energy.

By Andrew Zimmerman Jones Daniel Robbins. One of the consequences of Einsteins general theory of relativity was a solution in which space-time curved so much that even a beam of light became trapped. These solutions became called black holes and the study of them is one of the most intriguing fields of cosmology.

Black holes are the strangest objects in the Universe. A black hole does not have a surface like a planet or star. Instead it is a region of space where matter has collapsed in on itself.

This catastrophic collapse results in a huge amount of mass being concentrated in an incredibly small area. The gravitational pull of this region is so great that nothing can escape not even light. Black holes are one of the most mysterious and powerful forces in the universe.

A black hole is where gravity has become so strong that nothing around it can escape not even light. The mass of a black hole is so compact or dense that the force of gravity is too strong for even light to escape. Can we see them.

Black holes for dummies. Black holes are formed when giant stars explode at the end of their lifecycle. This causes an explosion called a.

What this means is that you require a velocity greater than the speed. Due to its small size and enormous mass the gravity will be so strong it will absorb light and become a black hole. Black holes are.

Weve covered a lot of incredible stuff but this week were talking about the weirdest objects in space. Stellar mass black holes form when a v. Time dilation and black hole event horizons both of which are explained below provide intriguing ways of extending human life and in science fiction theyve long provided the means for allowing humans to live long enough to travel from star to star.

A black hole is a location in space with such a strong gravitational field that the escape velocity exceeds the speed of light. What this means is that you require a velocity greater than the speed. A black hole is a region of space from which nothing can escape.

According to the general theory of relativity it is the result of the curving of spacetime caused by a huge mass. Around a black hole there is a position of no return called the event horizon. It is called black because it absorbs all the light that hits it reflecting nothing just like a perfect black body in thermodynamics.

The boundary of the region from which no escape is possible is called the event horizon. Black Holes for Dummies. 21 May 2012 Start your 30-day free trial of Unlimited to listen to this plus tens of millions more songs.

A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
