A new theory suggests early black holes might have consumed antimatter, explaining why our universe is mostly matter. This is a big change from previous ideas.

Black hole mergers put limits on star-destroying supernovae

Pair instability supernovae create a "mass gap" in black holes.

This evening I learned the following bizarre things:
0/ Colliding massive objects create gravity waves (this I already knew).
1/ When spinning black holes collide, they experience an acceleration at right angles to the sum of the spins.
2/ The bigger the black holes, the greater the acceleration and resulting speed.
3/ When this happens with galactic core supermassive black holes, this can exceed the escape velocity of the galaxies.
4/ When one of these high-speed supermassive black holes encounters a dust or gas cloud, it creates a contrail of stars! And we can see these star-contrails - straight lines of stars, scattered across the cosmos!

Thank-you Professor David Blair!

Hubble Sees Possible Runaway Black Hole Creating a Trail of Stars

There's an invisible monster on the loose, barreling through intergalactic space so fast that if it were in our solar system, it could travel from Earth to
