Our universe is so big that it seems like nothing outside of it can exist. Experts are starting to think that our universe may be inside a 4th-dimensional black hole.
Our universe started as a singularity, an infinitely hot and dense point in space. The same description the scientific community gives black holes, the universe in which we live black holes could be the same, according to experts such as James Beecham at CERN.
How Does A Black Hole Form
Black holes occur when massive stars die and collapse into infinitely dense, and small light isn’t even fast enough to escape anymore. The space boundary where light cannot escape or any object can return is known as the event horizon, according to Nasa. Of course, this sounds familiar, as the observable universe has its event horizon. During the first trillionth of a second after the Big Bang, the universe began a rapid expansion, even faster than the speed of light. Space didn’t exist until this point, so the universal speed limit didn’t exist either. Over time, the expansion of the universe slowed down.
According to Einstein’s theory of relativity, massive objects “warp” space-time, meaning the space around the black hole is curved. When it comes to viewing black holes, this would almost be impossible if not for the light and heat sucked into them. The more matter absorbs into the black hole, the black how grows and the event horizon with it. When the black hole grows, the rate at which material falls slows. Immense gravity slows things down to an observer, appearing as if nothing is moving. Although from the perspective of something pulled into the black hole, time seems normal according to the theory of relativity.
Are We Inside A Black Hole?
Three-dimensional black holes that occur in our universe have two-dimensional event horizons. By this logic, for our universe to be an event horizon, it would have to come from a fourth-dimensional black hole. Calculating what happens in the black hole’s singularity is an impossibility, which is why we get infinities, although calculating the event horizon is feasible with today’s knowledge and equations. The matter falls into the black hole, and the event horizon encodes it. As the black hole grows, so does the event horizon, so the surface area is precisely the size needed to contain all the information for all the matter that has fallen since the big bang. That information is the information of our universe. Surprisingly the math adds up and solves the need for answers to much-needed questions regarding our universe and black holes. According to researchers at the Perimeter Institute and the University of Waterloo, back in 2014.
“Is that the big bang hypothesis has our relatively comprehensible, uniform, and predictable universe arising from the physics-destroying insanity of a singularity. It seems unlikely.”
It is hard to imagine that our universe may exist inside another universal black hole. The black hole hypothesis seems to add up and fill in the missing pieces that scientists and experts have been chasing for a lifetime, leading us to believe our universe is vaster and a lot stranger than we once could’ve imagined.
