Our universe may reside within a vast, black hole. Let's rewind the clock. Before humans existed, before Earth formed, before the sun ignited, before galaxies arose, before light could even shine, there was the Big Bang. This happened 13.8 billion years ago.Our universe may reside within a vast, black hole. Let's rewind the clock.

Are black holes the end of the universe?
After 1043 years, black holes will dominate the universe. They will slowly evaporate via Hawking radiation. A black hole with a mass of around 1 M ☉ will vanish in around 2×1064 years. As the lifetime of a black hole is proportional to the cube of its mass, more massive black holes take longer to decay.
Why didn’t universe become a black hole?
The fact that the universe did not recollapse into a swarm of black holes is evidence that sharp density variations did not exist (or were extremely rare). This lack of sharp variations, in turn, is evidence for the inflationary model that most cosmologists today accept. Answer posted September 22, 2003.
How will universe end?
The Big Freeze. Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze. If the expanding universe could not combat the collective inward pull of gravity, it would die in a Big Crunch, like the Big Bang played in reverse.
How long is 1 minute in a black hole?
In other words, it is very dense. And because it is so heavy, it has the ability to completely stretch out space-time to a point where one minute on the edge of Sagittarius A* will see 700 years pass on Earth.
What is a white black hole?
White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.
Will our star become a black hole?
No. Stars like the Sun just aren't massive enough to become black holes. Instead, in several billion years, the Sun will cast off its outer layers, and its core will form a white dwarf — a dense ball of carbon and oxygen that no longer produces nuclear energy, but that shines because it is very hot.
Is time Travelling possible?
In Summary: Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.
Is the Big Rip possible?
One grim possible outcome is a Big Rip, which would ultimately unravel all matter down to the atomic level—though not for billions of years or longer.
What is Stephen Hawking’s black hole theory?
That's where Hawking came in. In 1971, he suggested that black holes formed in the chaotic environment of the earliest moments of the Big Bang. There, pockets of matter could spontaneously reach the densities needed to make black holes, flooding the cosmos with them well before the first stars twinkled.
