Is the Big Bang caused by a black hole?
Accordingly, the Big Bang was a nonsingular Big Bounce at which the universe had a finite, minimum scale factor. Or, the Big Bang was a supermassive white hole that was the result of a supermassive black hole at the heart of a galaxy in our parent universe.
Is the Big Bang the other side of a black hole?
No, a black hole can’t be the same thing as the Big Bang. The Big Bang singularity is an initial spacelike singularity which would be similar to the white hole.
Are black holes connected to each other?
WORMHOLES – tunnels through space-time that connect black holes – may be a consequence of the bizarre quantum property called entanglement. Black holes emit photons via something called Hawking radiation, and these are “entangled” with the interior of the black hole and also with each other.
What is the black hole theory?
A black hole is a region of spacetime where gravity is so strong that nothing — no particles or even electromagnetic radiation such as light — can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
What is Stephen Hawking’s black hole theory?
In 1971, Stephen Hawking proposed the area theorem, which set off a series of fundamental insights about black hole mechanics. The theorem predicts that the total area of a black hole’s event horizon — and all black holes in the universe, for that matter — should never decrease.
Do we live inside a black hole?
We can’t calculate what happens in a black hole’s singularity — the laws of physics literally break down — but we can calculate what happens on the boundary of an event horizon. We might live in a universe within a black hole within a universe within a black hole. It might just be black holes all the way down.
What are some of Stephen Hawking’s theories?
4 bizarre Stephen Hawking theories that turned out to be right (and 6 we’re not sure about)
- The Big Bang wins.
- Black holes are real.
- Hawking radiation.
- Black hole area theorem.
- The information paradox.
- Primordial black holes.
- The multiverse.
- Chronology protection conjecture.
Is there a white hole in our universe?
Matter can and would escape from white holes into the universe. Both white and black holes were entirely theoretical several decades ago, but now many actual astronomical objects are associated with black holes. So far, no astronomical source has been successfully tagged a white hole.
Were black holes born during the Big Bang?
But perhaps black holes were also born during the Big Bang itself. A hidden population of such “primordial” black holes could conceivably constitute dark matter, a hidden thumb on the cosmic scale. After all, no dark matter particle has shown itself, despite decades of searching.
Are ‘primordial’ black holes the hidden dark matter?
It was an old idea of Stephen Hawking’s: Unseen “primordial” black holes might be the hidden dark matter. It fell out of favor for decades, but a new series of studies has shown how the theory can work. Primordial black holes would cluster in distinct clumps throughout the universe.
Did Einstein’s theory of relativity lead to black holes?
Roger Penrose will describe his Nobel prize-winning work showing that Einstein’s general theory of relativity leads to the formation of black holes, something that Einstein himself did not believe happened in the real world.
What happened to the universe after the Big Bang?
More progress came in the 1990s. By then, theorists also had the theory of cosmic inflation, which holds that the universe experienced a burst of extreme expansion right after the Big Bang. Inflation could explain where the initial density fluctuations would have come from.
