What if I told you that black holes weren’t as bad as you thought they were? That they wouldn’t just crush life or anything for that matter when it came into contact with the black hole? With recent movies like Interstellar, scientists have been toggling the idea that it might be possible to go to another galaxy via black holes, instead of being big, death objects in our universe.
“What we did was to reconsider a fundamental question on the relation between the gravity and the underlying structure of space-time,” from the Diego Rubiera-Garcia team at University of Lisbon in Portugal.
If you realize what makes black holes so deadly, you would realize that it’s all caused by singularity. In Einstein’s theory of relativity, he explains that in the center of a black hole is where gravity is at its most intense – which is what we call this singularity. This is also where time seems to end, as well as space.
But if singularity were to not exist, and we were to put a wormhole there instead, could it be a viable answer to what a black hole actually is? Since singularity has yet to be actually proven, due to the fact we have not found a way to show that it exists, we’re able to play around with theories like this.
According to Science Alert, in order for something like this to work out, or for anything of our basic understanding of the universe to stay intact, we would definitely need Einstein’s theory of relativity to be wrong; which would basically change everything.
So, the big question is, if the possibility of a finite-sized wormhole being at the center of a black hole is possible, could we really send objects throughout? Maybe even humans?
Rubiera-Garcia’s team took three objects: a scientist, a chair, and a spacecraft (they call them observers) and tested their theory out.
“Each particle of the observer follows a geodesic line determined by the gravitational field. Each geodesic feels a slightly different gravitational force, but the interactions among the constituents of the body could nonetheless sustain the body,” says the Rubiera-Garcia team.
Perhaps if this is a liable theory, that means instead of being crushed while coming into contact with a black hole, we can only be crushed per size of the wormhole.
Although, this is to remain a theory until (hopefully, somehow in the future we can test this out. *wishful thinking*), it changes our entire thought process regarding what a black hole actually is. Luckily, it opens so many more doors and possibilities for the future of our universe.
I encourage you to read more about this from the Science Alert.
