When running Hawking and Hartles’ as well as Vilenkin’s, math, the new team didn’t get the teeny quantum fluctuations required to create today’s universe.
A new study suggests that the early Solar System was quickly divided in two, with the rapidly forming Jupiter creating the dividing line.
Did our sun have a twin when it was born 4.5 billion years ago? Almost certainly yes -- though not an identical twin.
New work from a team led by Carnegie’s Eduardo Bañados has discovered 63 new quasars from when the universe was only a billion years old.
Astronomers have used gravitational lensing to detect an incredibly faint early-universe galaxy 13 billion light years away.
Research has found new persuasive evidence that could help solve a longstanding mystery in astrophysics: why did the pace of star formation in the universe slow down some 11 billion years ago?
International collaboration including MPQ scientists sets a new value for the antiproton mass relative to the electron with unprecedented precision.
(PhysOrg.com) -- Suppose at some point the universe ceases to expand, and instead begins collapsing in on itself (as in the “Big Crunch” scenario), and eventually becomes a supermassive black hole. The black hole’s extreme mass produces an extremely strong gravitational field. Through a gravitational version of the so-called Schwinger mechanism, this gravitational field converts virtual particle-antiparticle pairs from the surrounding quantum vacuum into real particle-antiparticle pairs. If the black hole is made from matter (antimatter), it could violently repel billions and billions of antiparticles (particles) out into space in a fraction of a second, creating an ejection event that would look quite similar to a Big Bang.
By shooting a beam of neutrinos through a small slice of the Earth under Japan, physicists say they
Using the deepest X-ray image ever taken, astronomers found the first direct evidence that massive black holes were common in the early universe. This discovery from NASA
