Big Bang

Ethan Siegel on where it all came from…

Siegel: "there is no guarantee that what remains in the Universe, today, gives us sufficient information to find the answers." One way of looking at it is that, if we are characters in the story, we can’t meet the author. Read More ›

Sabine Hossenfelder asks: Will the Big Bang repeat?

Hossenfelder: I am not sure that CCC actually solves the problem it was supposed to solve. Remember we are trying to explain the past hypothesis. But a scientific explanation shouldn’t be more difficult than the thing you’re trying to explain. And CCC requires some assumptions, about the conformal invariance and the erebons, that at least to me don’t seem any better than the past hypothesis. Read More ›

How small was the universe when the Big Bang started?

Ethan Siegel offers an opinion at Forbes: No matter how tempting it may be to think that the Universe arose from a singular point of infinite temperature and density, and that all of space and time emerged from that starting point, we cannot responsibly make that extrapolation and still be consistent with the observations that we’ve made. We can only run the clock back a certain, finite amount until the story changes, with today’s observable Universe — and all the matter and energy within it — allowed to be no smaller than the wingspan of a typical human teenager. Any smaller than that, and we’d see fluctuations in the Big Bang’s leftover glow that simply aren’t there. Ethan Siegel, “How Read More ›

At National Geographic: A million to one odds that the universe’s expansion mystery is a statistical fluke

At NG: In other words, it’s looking even more likely that there’s some fundamental ingredient of the cosmos—or some unexpected effect of the known ingredients—that astronomers have yet to pin down. Read More ›

At CNN: The Problem with the Big Bang Theory

The story is really about the fact that inflation theory — way Cooler than the Big Bang — was not especially confirmed. Get this: it's important to remember that "there are no sacred cows in science, and scientists are always checking and rechecking even their favorite universal models.” – Don Lincoln Really, Don? Try doubting that humans are responsible for global warming and watch the herd of sacred cows stampede… Read More ›

Rob Sheldon on the current trend to non-theist intelligent design (ID) theory

When some people wrote privately to protest that this ET>Big Bang stuff is all just one space bunny too far down the cosmic path, I (O’Leary for News) pointed out in response that Neil deGrasse Tyson (here), Martin Rees (here), and Elon Musk (here) have also suggested that very thing. Well, now theoretical physicist Rob Sheldon writes to offer some thoughts on the new-found popularity. Read More ›

Physicist Brian Miller reflects on claims that the universe had no beginning

Miller: Sutter asserts that Bento and Zalel’s article offers a credible response against the evidence for a cosmic beginning. Yet this claim is only based on what might be possible in the realm of the imagination. Read More ›

Is Ethan Siegel’s Big Bang and Parallel Universes nonsense a response to Steve Meyer?

Now that Miller mentions it, several other anti-Big Bang tales have appeared recently. Perhaps the reason that all these stories seem extra-silly is that the authors are rattled. Read More ›
