Physics

A 31 minute SciShow video on how lead ingots which were recovered from a Roman shipwreck enabled the CUORE experiment's search for neutrinoless double beta decay, and the challenges of ethically sourcing "low background material".

Has anyone set aside lead (and other materials) as a stockpile of low background material for future generations of physicists? Seems like something The Long Now Foundation might do.

I must admit that the details of how the fields are coupled went over my head, but I found the rest of the video quite accessible. Professor Copeland is a joy to listen to, and Brady asks great questions as usual.

I also learned that "inflation" and "the big bang" are not synonymous, and inflation occurred first.

I think I need to rephrase the question. I'll post again in a few days.

The replies so far have generally been very polite, given the subject. I was nervous about that. Thanks everyone!

... Hear me out, okay?

Back in 2000 I took my first solo, out of state trip, to meet an online friend. When I got off the bus, she greeted me, and let me know that we had to go stop by her friends house on the way back.

She was Wiccan and needed some Spiritual guidance because the night before she saw a black portal open up in the corner of her room that was giving her really bad vibes.

It wasn't my thing, but I never discounted it. Maybe it was real, and if nothing else it's just how her mind is rationalizing things.

But I guess my question is: Does the Scientific Method rule out the possibility that a "real" portal appeared in her room?

Taking wave function probability into account and the absense of data from the room, is it fair to say that the scientific method doesn't rule out the black portal being real?

Looking for black and white answers if possible, but I'd also love to hear your reasoning~

So, I watched The Higgs Field, explained - Don Lincoln and there it explains that particles are massless and it is only through their interaction with the Higg's field that they gain mass. However, how are they "moving" through the Higg's field? Is it through a movement in the 3rd dimension or a dimension above?

And related, does the movement through the Higg's field generate gravitons that affect particles they interact with by "pulling" them in the opposite direction of which they were traveling?
