What is a black hole? In an article that has just appeared in the journal Nature Astronomy, LMU philosopher Erik Curiel shows that physicists use different definitions of the concept, depending on their own particular fields... more
Discovering new particles using black holes  PHYS.ORG · 2 weeks
Some theories that go beyond the Standard Model of particle physics predict the existence of new ultralight particles, with masses much below the lightest known particles in nature. When these particles have very weak interactions with... more
Scientists simulate a black hole in a water tank  PHYS.ORG · 2 weeks
Certain phenomena that occur in black holes but cannot be directly observed in astronomic investigations can be studied by means of a laboratory simulation. This is possible due to a... more
