A Quote by Seth Shostak
Clearly, enriching the cosmos with heavy elements takes a while. So there's inevitably an interval between the sterile aftermath of the Big Bang and a time when the cosmic chemistry set had enough ingredients to make rocky planets (and squishy biology).

55 Cancri is extraordinarily rich in heavy elements and extraordinarily efficient at making planets - much more so than our sun - and those elements are the very ones you need to make planets that aren't just gas giants.
Prebiotic chemistry on other worlds is going to be common. Plenty of small rocky planets will have similar chemistry. It's almost a given.
Chemistry seems to be pretty much nailed down, and biology gains ground all the time. But physics seems to be mired in idle rumination. They think a Big Bang started the universe, but they don't really know.
The language of chemistry simply does not mesh with that of biology. Chemistry is about substances and how they react, whereas biology appeals to concepts such as information and organisation. Informational narratives permeate biology.
The universe starts off with the Big Bang theory, and the first thing that emerged from the Big Bang is essentially hydrogen and then helium. And that's what combusts in stars. Finally, stars implode, and they build heavier elements out of that. And those heavier elements are reconstituted in the heart of other stars, eventually.
We saw a big bang in PCs; we saw a big bang in the Internet. I believe the next big bang is going to be even bigger. To be ready for that, we need to set the foundation, and that foundation is SoftBank Vision Fund.
I had done enough TV stuff before 'The Big Bang Theory.' I had done enough to sort of appreciate how awesome everybody is on 'The Big Bang Theory,' how nice and cool everybody is.
One can imagine that God created the universe at literally any time in the past. On the other hand, if the universe is expanding, there may be physical reasons why there had to be a beginning. One could imagine that God created the universe at the instant of the big bang, or even afterwards in just such a way as to make it look as though there had been a big bang, but it would be meaningless to suppose that it was created before the big bang. An expanding universe does not preclude a creator, but it does place limits on when he might have carried out his job!
We're quite happy with our Big Bang description of cosmic origins. But actually, the Big Bang accounts for what happened only after the beginning. The beginning itself, and especially what happened before, remains the biggest mystery of all.
Earlier generations of stars in the galaxy could well have had planets. But really, there was only hydrogen and helium to work with, so they'd all be gas giants and not small, rocky planets.
Man can be understood only by ascending from physics, chemistry, biology, and geology. In other words, he is first of all a cosmic problem.
Modern thinking is that time did not start with the big bang, and that there was a multiverse even before the big bang. In the inflation theory, and in string theory, there were universes before our big bang, and that big bangs are happening all the time. Universes are formed when bubbles collide or fission into smaller bubles.
Despite its name, the big bang theory is not really a theory of a bang at all. It is really only a theory of the aftermath of a bang.
First of all, the Big Bang wasn't very big. Second of all, there was no bang. Third, Big Bang Theory doesn't tell you what banged, when it banged, how it banged. It just said it did bang. So the Big Bang theory in some sense is a total misnomer.
I’m always the same. Whether I’m solo or with Big Bang, the one thing I have to do is sing and dance. I started solo activities with the things I did well with Big Bang, and I’ll show the things I learned while doing solo through Big Bang. Wherever I go and whatever I do, I am Taeyang and Dong Young Bae.
But if you think about a practical implication of enriching your life and giving you a sense of being part of a larger cosmos and possibly being able to use this [gravitational waves] as a tool in the future maybe to listen not just to black holes colliding, but maybe listen to the big bang itself, those kind of applications may happen in the not too distant future.
