The oldest and most distant black hole known to scientists dates back 13.3 billion years ago, when our universe was still in its teething stage.

Nothing can exceed the ultimate speed limit set by the laws of physics, known as the speed of light in a vacuum, or 299,792,458 m/s.

The odds that any given planet's gonna have complex life, I mean, this is really an opinion because we don't know about life anywhere else in the universe, but most of the scientists that I know and think about this deeply, I think the likelihood of life elsewhere is very high. It may not be the sort of life we're used to. It's not giraffes and redwood trees, but at least things like microbes.

The more curious we get about the great cosmic unknowns, the more unanswered questions our investigations of the Universe will reveal. Inquiring about the nature of anything - where it is, where it came from, and how it came to be - will inevitably lead you to the same great mysteries: about the ultimate nature and origin of the Universe and everything in it.

Researchers predict that the universe will reach its 'death date' at 33.3 billion years old, with approximately 19 billion years remaining before a Big Crunch occurs.
