  • In 2019, scientists detected gravitational waves that were later determined to come from the merging of two so-called "intermediate-mass" black holes.
  • These black holes were thought to exist, but had never been directly observed.
  • The discovery sheds new light on how black holes form.

Astrophysicists discover exotic merger of black holes

Gravitational wave researchers observe black holes of different sizes colliding for the first time.

Simulation of two black holes of different size orbiting each other, while emitting gravitational waves. Blue colors are weaker gravitational radiation and red is stronger.
  • Gravitational wave researchers at LIGO and Virgo observatories spot black holes of different sizes colliding.
  • The finding is unusual because previous black hole mergers involved partners of similar size.
  • The new information re-confirms Einstein's theory of relativity.

  • Columbia University astrophysicists discovered the cause of the unusual glow coming from regions of space with black holes and neutron stars.
  • The researchers ran some of the largest computer simulations ever to reach their conclusions.
  • They found that turbulence and reconnection of super-strong magnetic fields are responsible for the light.

Black hole death: How extreme tidal forces turn humans into spaghetti

Getting to close to a black hole is a nightmare waiting to happen.

  • Like ocean tides caused by gravity, a nearby black hole would create a 'tide' inside your body, which is mostly water.
  • As your body drew nearer to the black hole, your head would be stretched away from your feet.
  • Scientists call this streching "spaghettification", from the word of spaghetti.

Rotating black holes may serve as gentle portals for hyperspace travel

Feel like traveling to another dimension? Better choose your black hole wisely.

One of the most cherished science fiction scenarios is using a black hole as a portal to another dimension or time or universe. That fantasy may be closer to reality than previously imagined.
