«How do you build such a big black hole in such a short time?

Not exact matches

Everything with mass in the universe theoretically creates them — you and me included — but only highly cataclysmic events, such as exploding stars, colliding black holes, or the Big Bang, can generate waves that are powerful enough for LIGO to detect.

Such a theory would be crucial for explaining the first moments of the big bang, when the universe was dense, hot and small, or what happens near the singularity at the cores of black holes, where the effects of quantum physics may compete with those of general relativity.

Black holes that might have been created shortly after the big bang could constitute the universe's hidden mass, but they would have to exist in such abundance that we would likely have already discovered them through other means.

This sounds reasonable at first, but host galaxies are 10 billion times bigger than the central black holes; it should be difficult for two objects of such vastly different scales to directly affect each other.

As we noted, the LHC will not destroy the world and as George Musser wrote to me after we recorded the interview, «I said something to the effect that scientists had stocked [stoked] concerns about black holes by saying the LHC would create particles not seen since the big bang, but those particles have been seen since the big bang, namely in natural processes such as cosmic ray collisions; therefore if black holes posed a threat, the universe would already be a goner.»

Such isolated black holes would be too dim to discern at the galactic core, but the x-ray binaries serve as a tracer suggesting they're there — and in really big numbers.

Big black holes are spawned when a dying star collapses, packing so much mass into such a small space that gravity becomes overwhelmingly powerful.

The fact that several such pristine galaxies turn out to have a small, still - expanding black hole at their core suggests that black holes can grow to intermediate size without mergers, but then need to pool their resources to get much bigger.

u «The daunting problem for theories of structure formation in the Universe is to understand how such huge black holes [3 billion solar masses] and the vast reservoirs of gaseous fuel were assembled so soon after the Big Bang...» Edwin L. Turner, «Through a Lens Brightly,» Nature, 27 June 2002, p. 905.

For these waves to be big enough to detect, however, extraordinarily massive, astronomical objects are required, such as accelerating black holes or neutron stars.

The second, third, and fourth grade science word lists familiarize students with the planets, while the middle school science definitions introduce more challenging space science words such as the big bang theory and the concept of a black hole.
