Two physicists are trying to revive one of the great debates of twentieth-century science, arguing that the Big Bang may never have happened. Their work presents a radically different vision of the universe from the one cosmologists now work with.
"The Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there," says Dr. Ahmed Farag Ali of Benha University, Egypt. In collaboration with Professor Saurya Das of the University of Lethbridge, Canada, Ali has created a series of equations that describe a universe much like Hoyle's; one without a beginning or end.
They found that when using Bohm's work to make quantum corrections to Raychaudhuri's equation on the formation of singularities, they described a universe that was once much smaller, but never had the infinite density currently postulated.
Das and Ali propose that the universe is filled with a quantum fluid made up of gravitons, particles that probably have no mass themselves but transmit gravity the way photons carry electromagnetism. The follow-up paper suggests that in the early universe these gravitons would have formed a Bose-Einstein condensate, a collection of particles that display quantum phenomena at the macroscopic scale. Moreover, the paper argues that this condensate could cause the universe's expansion to accelerate, and so explain dark energy, and might one day be the only surviving component of the universe.
Although Das and Ali's vision appears to resolve a number of problems with the dominant cosmological models, it still requires extensive elaboration to test whether it has even larger problems of its own.

But, but, but it is SCIENCE!
I’m amazed that there are people who are on another level smarter than me.
I’m a college educated guy, but these folks who work in these fields are just different.
But can they throw a perfect spiral?

As we all well know, it’s God who created the entire “existence” of anything outside of himself, in those first six days of creation. On the 7th day, God rested ... from his creation activities ... and is now “maintaining” what has been created.
Some people just don’t want to believe God, when he speaks and reveals what only he knows!
The more we know, the more realize that we don’t know.
Any interesting predictions from the new theory, such as dampening of gravitational waves?
I don't know, the show name isn't catchy as the "Never Ending Universe Theory".
If you are working backwards towards a Big Bang singularity, you must inevitably get to a time when no physical laws existed. Nor did space. Nor did time.
"...darkness was over the surface of the deep and the Spirit of God was hovering over the waters. And God said, “Let there be light!”
“propose that the universe is filled with a quantum fluid made up of gravitons”
Step 1: prove gravitons exist.
We still have a serious lack of understanding about gravity and how it relates to anything else.
Lacking that, kinda pointless to make authoritative & disruptive proclamations about the origin of the universe.
It’s tough, I wish there were more of us around because it gets kinda loneseome
Good heavens Miss Sakamoto, you’re beautiful.
One of the things I enjoy about the TV show Big Bang Theory is that it demonstrates how people are smart in different ways, and stupid in different ways also.
That mimics my observation about life in my sixth decade.
“The Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there,”
Actually, the Laws of Physics were “invented” during the Big Bang, and could have been anything necessary to get it all started.
If the science isn’t settled on this....
It doesn’t claim to be authoritative.
Speculative science is important, giving new ideas to test.
Lots of science was advanced by testing unpopular theories and good or even wild guesses
Maybe the author of the comic strip "Dick Tracy" got his idea for an anti-gravity machine from the concept of gravitons?
Maybe we can do something with the gravitons. I am impressed!
