No Big Bang – Universe Always Was


Thought it all started with a big bang? Well, not so fast.

If a new theory turns out to be true, the universe may not have started with a bang.

In the new formulation, the universe has never been a singularity, nor an infinitely small and infinitely dense point of matter. In fact, the universe may not have a beginning at all. The model may also account for dark matter and dark energy, resolving multiple problems at once.

“The Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there,” Ahmed Farag Ali at Benha University and the Zewail City of Science and Technology, both in Egypt, told Phys.org.

“Our theory suggests that the age of the universe could be infinite,” said study co-author Saurya Das, a theoretical physicist at the University of Lethbridge in Alberta, Canada.

A little later in the article, Das hedges his bet a bit. He says:

But if there was no Big Bang, what is the history of our universe?

‘The universe could have lasted forever,’ speculates Professor Das.

‘It could have gone through cycles of being small and big or it could have been created much earlier.’

So, instead of 13 some billion years ago, it started, what, 25 billion years ago? Have they actually eliminated the need for a beginning, or just pushed it back a few billion or so years?

If there was no big bang how does that impact inflationary theory and multiverse. Can they still survive? es58
Yes, this desperate 'clutching at straws' by atheists should have been knocked on the head long ago, but atheists, I believe, are the like the Emperor, as naked as the day that he was born, but... but ... from basking in complacency induced by the sycophancy of their courtiers, they have, for a good while now, been feeling increasingly uncomfortable, almost as if they were naked....

To say the universe is infinite is nothing more than intellectual laziness due to the failings of Big Bang. Einstein's cosmological constant was created at a time when the universe was believed to be static. It should not work with Big Bang, but it does. Rather than ask the right questions, they simply toss the laws of physics completely. The biggest question is can something come from nothing? All matter must have a beginning, which is important to the second law of thermodynamics. BobRyan
@1 Well and tightly put, Fasteddious. Belfast
Hmmm, isn't there some famous physics theorem that proved the Universe had to have a beginning? And then there is the second law of thermodynamics that says if the universe was infinitely old, then it would have gone into heat death an infinite time ago as the entropy continued to increase and all energy or temperature differences approached zero. Finally, there is the conundrum that if the Universe is infinitely old, then an infinite time must have passed to bring us to today. How can an infinite amount of time actually have passed? That gets us into the metaphysics of mathematics. Fasteddious
