Albert Einstein: Expert outlines ‘astounding’ doomsday theory
The German physicist’s monumental theory paved the way for future scientists like Stephen Hawking to form their own thesis to explain the beginning of the universe. But despite general relativity’s significant status, many have tried to replace it as some experts consider it incomplete. And now, scientists from the University of Liverpool and Imperial College London have come up with a whole new theory of their own.
The experts investigated Chance Set Theory and looked deep into the study of how the cosmos began.
Chance Set Theory states that space and time have a fundamental unity, or quantum.
The pioneering figures in quantum mechanics defined light as being emitted in quantized “packages of energy,” and this theory says that spacetime is made up of its own package.
If chance set theory is correct, then there is a limit to how close two points can be to each other, and this limit is limited to the size of the “spacetime particle”.
An illustration of the Big Bang
In this way, not only does time become a physical manifestation, singularity becomes impossible.
Some scientists already take issue with the idea of a singularity as something infinitely dense has never been observed in the universe.
If singularity is impossible, then then the Big Bang may also be.
So after vigorous research, two researchers boldly put forward their theory that the universe has simply always existed.
Bruno Bento and Stav Zalel, from the University of Liverpool and Imperial College London, who undertook the research, explained why this is the case.

Mr Bento said: “in the original formulation and dynamics of the Causal Set, classically speaking, a causal set grows from nothing to the Universe we see today.
In our work, instead, there would be no Big Bang as a beginning, as the causal set would be infinite for the past, so there is always something before it.”
But this may not mean that the Big Bang never happened.
Instead, if the new theory is correct, it is more likely that the universe already existed before the Big Bang, but just don’t know anything about what it could have been like.
And today, many other scientists accept the notion that there were space events that occurred before the Big Bang.
Roger Penrose, the winner of a Nobel Prize for demonstrating, alongside Stephen Hawking, the properties of black holes, holds this view.

The two scientists have defended the concept that there was another universe existing before ours, specifically another cosmos that expanded and then retracted until it returned to singularity.
The difference between this hypothesis and the Causal Set Theory is that, in the latter, there is no singularity.
The study is in pre-print on arXiv and is awaiting peer review.
It is important to note, however, that it is only a hypothesis at the moment.
They carry the term “theory” because they are mathematical theories, that is, they have their own set of axioms, postulates and elements.
To be considered a physical, or a scientific, theory, its predictions must be tested.
Einstein’s general theory of relativity was published more than a century ago, to refine Isaac Newton’s law of universal gravitation.
Providing a description of gravity as a geometric property of space and time, or spacetime, this model is still used by scientists as an explanation of gravitation in modern physics.
Einstein’s theory has important astrophysical implications as it also alludes to the existence of black holes – cosmic phenomena in which space and time are distorted in such a way that nothing, not even light, can escape.
