# More Big Bangs Could Be Coming Up, Scientists Say

## Big Bounce

Researchers suggest the universe may never actually end, but instead lead to future Big Bangs, much like the one believed to have brought the whole mess into being in the first place.

As detailed in a [yet-to-be-peer-reviewed paper](<https://arxiv.org/pdf/2302.03710.pdf>), first [spotted by *LiveScience*'s Paul Sutter](<https://www.livescience.com/dark-energy-could-lead-to-a-second-and-third-and-fourth-big-bang-new-research-suggests>), two theoretical physicists at the University of Portsmouth suggest that dark energy, the mysterious stuff suspected to be behind the accelerating expansion of the universe, may simply switch on and off, a process that could eventually lead to the next Big Bang.

## Contract Obligations

There's a lot surrounding our theory of how the universe began that is still not fully understood, including a "singularity" following the Big Bang, which suggests a point of "infinite density where the math breaks down," as Sutter explains, as well as a period of "inflation," a rapid expansion of the universe during its earliest stages.

The authors of the new paper suggest that dark energy may have always been a part of this push-and-pull dynamic, and that the Big Bang was simply one in an infinite line of other Bangs, a theory known as the "[Big Bounce](<https://futurism.com/scientists-origin-universe-big-bang>)" — which effectively means a singularity never had to happen in the first place.

In other words, dark energy could lead to a "Big Crunch," causing the universe to contract and eventually "Bang" again, rinse and repeat.

## Making Up Numbers

But the dark energy model comes with some drawbacks. As the researchers admit in their paper, they had to insert an artificial value to explain the current rate of the universe's expansion, as predicted by quantum mechanics.

However, that doesn't mean the research is completely useless.

"Nonetheless, our qualitative analysis serves as a basis for the construction of more realistic models with realistic quantitative behavior," the paper reads.

In short, we still don't know the ultimate fate of our universe, but we might be getting closer to an answer.

## Author
I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida.
