The resultant blast created an ever-expanding universe that, eventually, became home to the planet we call Earth.
The Big Bang theory first appeared in a scientific paper in 1931.
Physicist Georges Lemaitre is credited with its creation.
And the bulk of our assumptions about the universe and its rate of expansion are based on his ideas.
But what if the Big Bang wasnt the beginning?
Chanda Prescod-Weinstein, a physicist at the University of New Hampshire, has a differing theory.
Writing for New Scientist, they claim it makes more sense to assume the universe has been expanding forever.
One that was expanding exponentially even before what we call the big bang.
Mathematically, this seems the most likely scenario assuming inflation is correct.
But, if timesalwaysexisted because the universe itself has always existed then perhaps itsneverexisted.
What is time without a beginning or end?
