New Model of the Universe with no start or finish

This model has no big bang, but it does not involve a god.

Big Bang Abandoned in New Model of the Universe

A new cosmology successfully explains the accelerating expansion of the universe without dark energy; but only if the universe has no beginning and no end.

As one of the few astrophysical events that most people are familiar with, the Big Bang has a special place in our culture. And while there is scientific consensus that it is the best explanation for the origin of the Universe, the debate is far from closed. However, it's hard to find alternative models of the Universe without a beginning that are genuinely compelling.

That could change now with the fascinating work of Wun-Yi Shu at the National Tsing Hua University in Taiwan. Shu has developed an innovative new description of the Universe in which the roles of time space and mass are related in new kind of relativity.

Shu's idea is that time and space are not independent entities but can be converted back and forth between each other. In his formulation of the geometry of spacetime, the speed of light is simply the conversion factor between the two. Similarly, mass and length are interchangeable in a relationship in which the conversion factor depends on both the gravitational constant G and the speed of light, neither of which need be constant.

So as the Universe expands, mass and time are converted to length and space and vice versa as it contracts.

This universe has no beginning or end, just alternating periods of expansion and contraction. In fact, Shu shows that singularities cannot exist in this cosmos.

It's easy to dismiss this idea as just another amusing and unrealistic model dreamed up by those whacky comsologists.

That is until you look at the predictions it makes. During a period of expansion, an observer in this universe would see an odd kind of change in the red-shift of bright objects such as Type-I supernovas, as they accelerate away. It turns out, says Shu, that his data exactly matches the observations that astronomers have made on Earth.

This kind of acceleration is an ordinary feature of Shu's universe.

That's in stark contrast to the various models of the Universe based on the Big Bang. Since the accelerating expansion of the Universe was discovered, cosmologists have been performing some rather worrying contortions with the laws of physics to make their models work.

The most commonly discussed idea is that the universe is filled with a dark energy that is forcing the universe to expand at an increasing rate. For this model to work, dark energy must make up 75 per cent of the energy-mass of the Universe and be increasing at a fantastic rate.

But there is a serious price to pay for this idea: the law of conservation of energy. The embarrassing truth is that the world's cosmologists have conveniently swept under the carpet one the of fundamental laws of physics in an attempt to square this circle.

That paints Shu's ideas in a slightly different perspective. There's no need to abandon conservation of energy to make his theory work.

That's not to say Shu's theory is perfect. Far from it. One of the biggest problems he faces is explaining the existence and structure of the cosmic microwave background, something that many astrophysicists believe to be the the strongest evidence that the Big Bang really did happen. The CMB, they say, is the echo of the Big bang.

How it might arise in Shu's cosmology isn't yet clear but I imagine he's working on it.

Even if he finds a way, there will need to be some uncomfortable rethinking before his ideas can gain traction. His approach may well explain the Type-I supernova observations without abandoning conservation of energy but it asks us to give up the notion of the Big Bang, the constancy of the speed of light and to accept a vast new set of potential phenomenon related to the interchangeable relationships between mass, space and time.

Rightly or wrongly, that's a trade off that many will find hard. Let's hope Shu sticks to his guns, if only for the sake of good old-fashioned debate

The big bang model has problems, but nearly everyone accepts it.

This model also has problems, but no need to come up with dark energy. No need to conveniently swept under the carpet one of the fundamental laws of physics.

This new model can not at the moment explain cosmic microwave background, but in time it might be able to. Cosmic microwave background does not have to be the result of the big bang.

Question: Did you hear a big bang?

Answer: No, you must be hearing things.

I do not agree with this new model or the bang one.

My model involves the creator God.

by who me
once there was THE BAR, and the bar there was. and ALL was in the bar, for the bar was all and thous in the bar did not go out for there was nought outside.
then came the BIG bang, well actually allot of bangs of varying size. Those in the bar when out and looked at what they had done and said "what a mess, lets go back in and have a drink."

and so they went back inside and drank the holy Stoli for it was good and good it was. so were brought to us the first words of the universe, and That is why we on the appointed holy days go to the the bar, that is a reflection of the The one and true BAR and drink the holy Stoli and it is good.
So we honer and praise the Big bang (and all the bangs that followed that created the mess that we all live in till the end of time when all shall return to the one and true BAR.

from the book of Stoli napkin one verse one
the holy texts of the Stolians.

So...if I go to the bar and drink enough Stoli I get a big bang at the end of the night? That's what I got out of it anyway.

that is what the napkin says, if the bang is literal or figurative is still being debated. but the napkins say a lot. including
