  1. Sonic Black Hole Human made black holes which trap sound waves By Trevor Sherman, Bradley Valcin, and Mia Daveys

  2. Summary on the article On January 17, 2009, Israeli scientists created a black hole. The black hole is different than other black holes. This one is a black hole is for taking in sound waves while others take in light. To create a sonic black hole, scientists created a Bose-Einstein condensate, a cloud of atoms cooled to almost absolute zero that acts like a light wave. The Israeli scientists created two clouds of rubidium (which have 87 atoms apiece) and are cooled to 50 nano Kelvins. The two clouds are separated by a small gap.

  3. Black hole traps sound waves Sound waves move to slowly to get out of the black hole cloud cloud Sound waves atom Rubidium cloud with 87 atoms, cooled to 50 nano Kelvins Rubidium cloud with 87 atoms, cooled to 50 nano Kelvins Low Density Spot/ Gap Atoms are moving at a speed of 3 millimeters per second Light waves move faster than sound waves so they manage to get out of the black hole Light waves

  4. Continued summary Since atoms move between the clouds faster than sound, sound waves can’t escape the sonic event horizon. Since its not a true black hole though, light waves are able to escape from it. Example of a black hole though it doesn’t really look like this

  5. Possible Future Implications This black hole could greatly impact our future. Here are some examples of what it could do. • It could make Earth less noisy by getting rid of sound waves • People could maybe find a way to use trapped sound waves as an energy source • It could help us learn more about black holes
