the Devil's Triangle

Image
The Devil’s Triangle Bermuda Triangle, section of the North Atlantic Ocean off North America in which more than 50 ships and 20 airplanes are said to have mysteriously disappeared. The area, whose boundaries are not universally agreed upon, has a vaguely triangular shape marked by the Atlantic coast of the Florida panhandle (in the United States), Bermuda, and the Greater Antilles. The Triangle The area referred to as the Bermuda Triangle, or Devil’s Triangle, covers about 500,000 square miles of ocean off the southeastern tip of Florida. When Christopher Columbus sailed through the area on his first voyage to the New World, he reported that a great flame of fire (probably a meteor) crashed into the sea one night and that a strange light appeared in the distance a few weeks later. He also wrote about erratic compass readings, perhaps because at that time a sliver of the Bermuda Triangle was one of the few places on Earth where true north and magnetic north lined up. Why ...

Black hole

Image
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. Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars. How Big Are Black Holes? Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or "stuff," in an object. Another kind of black hole is called "stellar." Its mass can be up to 20 times more than the mass of the sun. There may be many, many stellar mass black holes in Earth's galaxy. Earth's galaxy is called the Milky Way. The largest...

Is there another you in Parallel Universe?

Image
A world that exists in addition to, and is like, the world that we know, but that is also different from it in important ways A universe that may exist in addition to our own universe, but that is not known. Parallel universes are no longer just a feature of a good sci-fi story. There are now some scientific theories that support the idea of parallel universes beyond our own. However, the multiverse theory remains one of the most controversial theories in science.  Our universe is unimaginably big. Hundreds of billions, if not trillions, of  galaxies (opens in new tab)  spin through space, each containing billions or trillions of  stars (opens in new tab) . Some researchers studying models of the universe speculate that the universe's diameter could be 7 billion  light-years (opens in new tab)  across. Others think it could be infinite. But is it all that's out there? Science fiction loves the idea of a parallel universe, and the thought that we...
