Steven Weinberg mentioned god and dark energy when asked about the multiverse
I was flipping through some Quanta magazine articles, and came to a 2015 interview. He was asked about the multiverse hypothesis (which Alan Guth says is more likely than not, with the existence of the early inflation field), by the interviewer.

Weinberg said:

I am not a proponent of the idea that our big bang universe is just part of a larger multiverse. It has to be taken seriously as a possibility, though. And it does lead to interesting consequences. For example, it would explain why some constants of nature, particularly the dark energy, have values that seem to be favorable to the appearance of life. Suppose you have a multiverse in which constants like dark energy vary from one big bang to another. Then if you ask why it takes the value it does in our big bang, you have to take into account that there's a selection effect: It's only in big bangs where the dark energy takes a value favorable to the appearance of life that there's anybody around to ask the question.

This is very closely analogous to a question that astronomers have discussed for thousands of years, concerning the earth and the sun. Why is the sun the distance that it is from us? If it were closer, the Earth would be too hot to harbor life; if it were further, the Earth would be too cold. Why is it at just the right distance? Most people, like Galen, the Roman Physician, thought that it was due to the benevolence of the gods, that it was all arranged for our benefit. A much better answer - the answer we would give today - is that there are billions of planets in our galaxy, and billions of galaxies in the universe. ...a few of them ... are positioned in a way that's favorable for life.

The Big Bang, combined with the Dark Energy theory, does actually involve theological explanations by some. It might explain why some will bring god/gods into the discussion.

( One poster attempted to get around my suggestion, that space expansion, at the galaxy level, at the present time, has not been demonstrated, by bringing god/gods into the discussion. The comment was clearly an attempt to twist and confuse my points, but the poster bragged, in a subsequent post, about what a clever attack he was making.)

It is interesting that the issue of the (possible) multiverse will quickly become something of a theological issue. The first ever proponent of the Big Bang, George's Lemaitre, in a 1927 scientific paper, had to remove references to the biblical book of Genesis from his theory.

I would urge posters here to avoid dishonest behavior, while discussing scientific theories. Religion and science have a complicated relationship, because both try to answer some of the same questions. George Gamov erroneously said that Hoyle's Steady State theory was the official theory of the Soviet Union, while Hoyle made far too much out of the Pope's support for the Big Bang theory. (In reality, the whole theological angle had little to do with the scientific work while both theories could be used to argue for or against a god/gods)

Not will but is. Everything in cosmology raises theological issues for those religiously enamored.

We'll disagree on the emotional overtones of your little whine. Anyone interested in details can see Message 51.

The first ever proponent of the Big Bang, George's Lemaitre, in a 1927 scientific paper, had to remove references to the biblical book of Genesis from his theory.

They were originally in there because, as ignored facts would have it, Fr. LemaƮtre was an ordained catholic priest. Of course he saw his hypothesis in biblical terms.

These religious treatments are to be expected from those attempting to shoehorn the new views into their stone-age philosophies.

Other than an astute observation and opinion, do you see something of more significance to his answer?

Re: Steven Weinberg mentioned god and dark energy when asked about the multiverse
He was asked how we can test the multiverse theory, when we can't observe it.

He went on to tell us how we can perform tests that will give us a likely answer.

(It's possibility of having a demonstrable existence was heavily tied to observations surrounding String Theory)

(He also mentioned the scaler field particle, the Higgs Boson, but that was earlier, I think. It helps to provide infirect evidence for the Inflaton particle, along with the WMAP evidence, I believe)

InciWeb the Incident Information System

Northern Minnesota has the only fires in the eastern half of the US. There are also fires to the north in Ontario.

By far the largest Minnesota fir is the Greenwood fire, currently at about 26,000 acres, which is pretty small relative to what's happening out west.

We got a quality rain Saturday evening and night, which should have much helped things.

And So?
Steven Weinberg mentioned god and dark energy when asked about the multiverse

He also mentioned the scaler field particle, the Higgs Boson, but that was earlier, I think. It helps to provide infirect evidence for the Inflaton particle, along with the WMAP evidence, I believe

He mentioned some of your favorite buzz words: Higgs, multiverse, god etc.

And this is significant, how?

Re: And So?
He did not mention god when he was asked if the multiverse theory could ever be tested. He earlier mentioned the god issue.

(You combined words from an earlier post, when gods were mentioned, by me. If you cant label my quotes, with a post number, then at least use a 4 dot ellipsis between quotes)

Higgs was mentioned earlier in his interview. I mentioned it because Higgs is a scaler field particle. It provides a hope that an inflation field particle can possibly exist ( hope as in a hope to find answers). The existence of the Alan Guth inflaton particle is powerful evidence for a multiverse.

But he did mention the god issue and you must have given it significance enough to point that out. Even in your title.

Having problems following the discussion?

Higgs was mentioned earlier in his interview. I mentioned it because Higgs is a scaler field particle. ... (ellipses)

So there is no significance to why Dr. Weinberg uttered the word "god". It was just a part of the history he was relaying. Yes, I read the article.

Ok.

Re: And So?
I don't think that mentioning the god issue, while looking at the possible multiverse existence, should be described as a historical tidbit.

It might be considered a rebuttal to the early 1980s stuff Fred Hoyle was putting in his books. About some sort of intelligence creating the Universe we all know of. I think Hoyle coined a technical term, called "anthropic". Fred Hoyle knew how to write books that would be widely cited. He attempted to "go viral" before the internet age.

That aside, I dont see the multiverse as an old theory.
