#5: Is the universe a hologram? The strange physics of black holes | Top 10 2019

This post was originally published on this site

  • Big Think’s fifth most popular video of 2019 explains that, because energy cannot be destroyed, only transformed, some argue that information — arguably a form of energy — cannot be destroyed either. So then, what happens to information when it is absorbed into a black hole? Scientists don’t know for certain, but some posit that it may be possible for it to leak away from the black hole over time.
  • Black holes may hold information in a two-dimensional manner similar to a hologram, which take on three dimensions when light is shone through them. Some theorize that the underlying nature of reality can be glimpsed through black holes — that all the information about the entire universe is somehow held on a two-dimensional space of something.
  • To better understand how black holes work, as well as the elements surrounding them, we may need a level of physics to be developed.
