That is a theory. That black holes may warp space and time, to fit an an entire universe inside it.
no. a universe is everything. so technically theyre arent other universes.
It is thought that there are other universes that look like ours. It is also been suggested that there are an infinite number of universes.
There has been a lot of speculation about other universes, but it is just that: speculation. There is no firm evidence that other universes actually exist. Nor, for that matter, is there any firm evidence that other universes DON'T exist.
Examples of vacuums include the vacuum inside a sealed jar, the vacuum of outer space, and the vacuum inside a vacuum cleaner.
No
Parallel universes may, or may not, exist. While it is hypothesized that there may be other universes, there is no certainty that they do exist - nor, for that matter, is there any certainty that they DON'T exist. Since we don't know whether such "ohter universes" exist, we don't know what they look like either - although it has been speculated that other universes may have a different number of dimensions, or there may be other significant differences in physical laws, compared to our own universe. If this is the case, most such universes may be unsuitable for any sort of life.
'Multiverse' is an abstract noun because by definition it is purely hypothetical. It suggests the possibility of other universes and by definition we could never physically interact with other universes even if they exist. Other universes are not perceptible to our senses. They are physically disconnected from our universe.
The existence of multiple universes is a theoretical concept in physics, such as the multiverse theory. Some formulations of this theory suggest the possibility of parallel universes or alternate realities, but currently, there is no empirical evidence to support the existence of other universes beyond our own. It remains a topic of ongoing scientific investigation and debate.
That is unknown. Some hypotheses based largely in mathematics have suggested that this is possible, but there is no direct eveidence that other universes exist.
If blackholes reach the earth the earth will destroy. Blackhole are to large it can eat star easily.
Stephen Hawking is currently researching the origins of blackholes and the effects of blackholes on the matter surrounding it.
According the the Multiverse Theory, our universe exists as a bubble among a plane of countless other universes, though that's not the limit to how many there are. This plane, which contains many universes, is just a bubble itself, floating in a sea of other bubbles. This sea is just a bubble, too, on a plane of other bubbles, each containing planes, seas, bubbles, planes, and bubbles. According the the Multiverse Theory, there are an infinite number of other universes.
