9 thoughts on “ Through Black Holes

  1. Black holes may solve some of the mysteries of the universe. A black hole is a place in space where gravity pulls so much that even light cannot get out.
  2. A black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c 2 would take less than 10 −
  3. Apr 15,  · Einstein's theory of relativity paved the way for black holes' discovery, but the concept behind their existence was so bizarre that even the scientific visionary was not convinced.
  4. May 17,  · Just as we cannot see what is going on inside black holes in the cosmos, any observers in the parent universe could not see what is going on in ours. The motion of matter through the black hole's boundary, called an "event horizon," would only happen in one direction, providing a direction of time that we perceive as moving forward.
  5. Jan 25,  · Flying Through a Black Hole. My team at the University of Massachusetts Dartmouth and a colleague at Georgia Gwinnett College have shown that all black holes are not created equal. If the black hole like Sagittarius A*, located at the center of our own galaxy, is large and rotating, then the outlook for a spacecraft changes dramatically.
  6. If a black hole passes through a cloud of interstellar matter, for example, it will draw matter inward in a process known as accretion. A similar process can occur if a normal star passes close to a black hole. One Star's End is a Black Hole's Beginning. Most black holes form from the remnants of a large star that dies in a supernova.
  7. Aug 23,  · Under certain circumstances, a message could be passed through a theoretical wormhole connecting black holes in different universes, physicists have found in a new study. Unfortunately, their Author: Mara Johnson-Groh.
  8. In doing so, the black holes lose mass, because according to Einstein's famous E = mc^2 equation, energy and mass are equivalent. Black holes eventually evaporate, but you would be waiting around.
  9. Jan 13,  · Black holes aren’t that sort of black. They’re black because even light, the fastest thing in the Universe, has given up trying to escape their immense gravity. Let’s aim for a little context.
