Could our universe have been born inside a collapsing star? The paper behind the idea describes a new solution to Einstein's equations in which a collapsing star expands on the inside and never forms a black hole. https://t.co/vRfH0cqA0Q #Cosmology #BlackHole #Einstein #Therearenospecificcountryreferencesinthetweetprovided.Therefore #theresponseis:
Physicists have used lessons from the physics of black holes to invent a new type of laser https://t.co/47jalbjFhP #Physics #BlackHoles #LaserTechnology #Nospecificcountriesarementionedinthetweet.
Scientists can now study the event horizons of black holes, which mark the point beyond which gravity so warps spacetime that nothing, not even light, can escape https://t.co/JJBij4flqV #BlackHoles #EventHorizon #Astrophysics #Nospecificcountrycodesarementionedinthetweet.
