A new quantum equation suggests that the Universe has no beginning or end, and it could also account for dark matter and dark energy.

Researchers have created a new model that applies our latest understanding of quantum mechanics to Einstein’s theory of general relativity – and according to their calculations, the Universe may have been going forever.
It’s currently widely accepted that the Universe is around 13.8 billion years old, and before that everything in existence was squished into a tiny point – also known as the singularity – which was so infinitely dense that we can’t see anything before it. From there it famously exploded into a “Big Bang”.
This theory was derived from the mathematics of general relativity, but scientists have one big issue with it – it only explains what happened immediately after the Big Bang, not what happened during or immediately before it.
„The Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there,“ co-creator of the new model, Ahmed Farag Ali from Benha University and the Zewail City of Science and Technology, both in Egypt, told Lisa Zyga from Phys.org.
Working with Sauya Das at the University of Lethbridge in Alberta, Canada, Ali has now managed to resolve the issue by creating a new model in which the Universe is infinite, and the Big Bang singularity never occurred.
