Physicists agree that 13-15 billion years ago our universe was shaped by a Big Bang. But where did that Big Bang come from? A new theory suggested by a group of physicists offers the likelihood that our universe is nestled inside a black hole. We may have a mother universe that is one of many universes, and black holes may be the passageways among them, as reported by National Geographic.
Dr. Nikodem Poplawski of the University of New Haven is one such physicist supporting this yet unprovable theory, according to The Mother Nature Network. Black holes are generally believed to be "death traps" with gravity that works like a high-powered vacuum from which nothing, even light, can escape. They are thought to be at the center of every galaxy, including our Milky Way. Once these black holes touch the limit of their singularity, according to Dr. Poplawski, and can no longer withstand the weight, of say, billions of suns, it leads to a big bang.From The Mother Nature Network:
"According to Dr. Poplawski, the reason for such a limit (and, subsequently, the universe-creating explosion that follows) is that black holes spin. They spin at near-light speeds. This, in turn, produces a huge amount of torsion. Thus, such massive black holes are not just extremely tiny and enormously heavy, they are also twisted and compressed. The multitude of forces at work are so powerful that a bursting point is ultimately reached. This, Poplawski suggests, is how the Big Bang happened, however he prefers to call it 'the big bounce.'"Dr. Michio Kaku has written about why he thinks the name "Big Bang" does not effectively describe the birth of our universe, and argues that string theory could best explain what created it:
"First of all, the Big Bang wasn't very big. Second of all, there was no bang. Third, Big Bang Theory doesn't tell you what banged, when it banged, how it banged. It just said it did bang. So the Big Bang theory in some sense is a total misnomer.
This black hole argument to explain the Big Bang is yet another one in support of the Multiverse Theory, which was once considered "the crazy aunt of quantum theory."
i want to propose a new theory.
ReplyDeleteIs gravity directly proportional to mass and inversely proportional to time.
Can we create a black hole; if we accelerate a mass of alpha particle in speed of light spirally?
nonsense
DeleteWhy do you say nonsense?
DeleteThe LHC is an experiment designed to look for new particles and other undiscovered physical phenomena. One of these is the hypothetical existence of extra dimensions.
Delete"Extra dimensions" sounds very science-fictiony, but it doesn't mean "parallel dimensions of reality" or anything like that, it just means there might be additional spatial dimensions in addition to the 4 dimensions that we know of: 3 spatial dimensions (length, width and height) and 1 time dimension.
If extra dimensions do exist, then they are very hard to detect, which is why we haven't seen them yet. However, one proposed method of detection is as follows.
Assuming that the extra dimensions have some specific properties, then it might be possible that if you put enough energy in one place you will get some effect due to the extra dimensions which you will then be able to detect.
These effects come from the hypothetical possibility of a "quantum black hole" (or "micro black hole"). This is a very very very very very tiny black hole, tinier than a proton, which will exist only for a very very very very very tiny fraction of a second and then immediately evaporate.
Since it's so tiny and evaporates so quickly, we won't even see this quantum black hole. The only thing we'll see is some particles that were left after the black hole evaporated.
It's important to realize that these hypothetical quantum black holes are not the kind that can grow. In order to create an actual, stable, black hole you would need an insanely large amount of energy that no technology that exists now or will exist in the foreseeable future will even come close to.
With the tiny and almost insignificant amount of energy that the LHC has, we can never hope to create stable black holes even in our wildest dreams!
So what we can do? If extra dimensions actually exist, and if they have suitable properties, then we might fantasize about maybe creating a really really tiny quantum black hole that will exist for an extremely short duration of time and then immediately disappear.
We are not anywhere close to creating stable black holes that can grow in size, and we will not be anywhere close to it in this century or the next.
