Black Holes and Event Horizons - Facts and Pictures of Black Holes
Black Holes
What are Black Holes? Where do Black Holes come from? Who theorized about Black Holes? Who coined the term Black Holes?
Black Holes Pictures
Formed when a massive star collapses from its own gravity, black holes have such a strong pull of gravity that not even light can escape from them. Today's scientists believe that a black hole is the end product in the lifecycle of a giant star. If this star is three or four times as massive as our own sun, even after it has exhausted all its fuel, then it can collapse under its own gravity.
Black Holes - The Inescapable Truth About Black Holes.
Scientists believe black holes are the end product in the lifecycle of giant stars. If a star is 3 or 4 times as massive as our own sun, even after it has exhausted all its fuel, it can collapse under its own gravity. Just like a crab burying itself at the beach and pulling the sand down over itself, the collapsing star pulls in everything around it as well. Discover information and pictures.
Black Holes Shed Light on Galaxy Formation
Astronomers are concluding that monstrous black holes weren't simply born big but instead grew on a measured diet of gas and stars controlled by their host galaxies in the early formative years of the universe. Find more black holes information and pictures of black holes.
Black Holes
A favorite phenomenon of science fiction writers, black holes are real objects that play an important role in our Universe. They are different types of black holes, arising from different processes. But they all have one thing in common, they are incredibly dense regions of space that have gravitational fields so strong that not even light can...
Supermassive Black Holes
Supermassive black holes are some of the most powerful objects in the Universe. These incredible objects hold entire galaxies together and are capable of releasing incredible amounts of energy. Their formation is still a mystery. And some believe they may hold the key to exotic subjects of science fiction like interstellar travel and, possibly,...
Creating Black Holes
On of the tenets of stellar evolution holds that main sequence stars more than 25 times the mass of the Sun will eventually transition to a black hole in a brilliant supernova explosion. However, recent results appear to challenge that theory. Are we are the verge of a realignment of our current understanding, or is there another answer?
Wormholes
One of the theoretical consequences of general relativity is the existence of regions of space known as wormholes. While it is not completely understood how such places are created, there is currently no observational evidence to prove that they do, they could provide a means of traveling across the Universe nearly instantaneously. So what is...
Time Travel into the Past
There have been times when I wish that I could revisit the past. Perhaps to undo a mistake, or to visit a hero of history. Time travel is an often used plot device in many science fiction works, but is there any science behind it? Is it possible to time travel into the past?
