Title: Another ‘settled science’ topic is not so settled after all – Big Bang theory questioned

We’ve all heard of the claim of “settled science” when it comes to global warming/climate change, and we’ve all heard of the “Big Bang Theory”, and I’m not just talking about the popular TV show. The scientific theory goes all the way back to 1927.

This is an artist’s concept of the metric expansion of space, where space (including hypothetical non-observable portions of the universe) is represented at each time by the circular sections. Note on the left the dramatic expansion (not to scale) occurring in the inflationary epoch, and at the center the expansion acceleration. The scheme is decorated with WMAP images on the left and with the representation of stars at the appropriate level of development. Credit: NASA

The Big Bang theory is the prevailing cosmological model for the birth of the universe. It states that at some moment all of space was contained in a single point from which the Universe has been expanding ever since. Modern measurements place this moment at approximately 13.8 billion years ago, which is thus considered the age of the universe. After the initial expansion, the Universe cooled sufficiently to allow the formation of subatomic particles, and later simple atoms. Giant clouds of these primordial elements later coalesced through gravity to form stars and galaxies. The Big Bang theory does not provide any explanation for the initial conditions of the Universe; rather, it describes and explains the general evolution of the Universe going forward from that point on. (Source: Wikipedia) Now, it seems there’s a challenge to this ‘settled’ science, and a new quantum equation predicts the universe has no beginning. (Phys.org) —The universe may have existed forever, according to a new model that applies quantum correction terms to complement Einstein’s theory of general relativity. The model may also account for dark matter and dark energy, resolving multiple problems at once. The widely accepted age of the universe, as estimated by general relativity, is 13.8 billion years. In the beginning, everything in existence is thought to have occupied a single infinitely dense point, or singularity. Only after this point began to expand in a “Big Bang” did the universe officially begin.

Although the Big Bang singularity arises directly and unavoidably from the mathematics of general relativity, some scientists see it as problematic because the math can explain only what happened immediately after—not at or before—the singularity.

“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.

You have to change your opinion again. Here is your new one.

My position remains the same.

You can't hang that one on me, dude.
The Big Bang happened long before my time.
Someone else must've done it.

Misleading article - an observation was discredited as having its data compromised - the theory of the big bang would have been confirmed if that observation was deemed valid. We are back to where we were before on the Big Bang being one theory (though widely held as the best one so far) of many.

Once again you are assuming facts not in evidence.

Here is your new one.

Thanks,but I will pass. I just don't care.

I am curious about it's effect on YOUR opinions,though. Are miracles affected by this new theory? What about virgin birth from a married woman?

It is very pleasant to change one's opinion and to learn new things.
