So the first at home Covid test is available. Awesome. I think it should be made available to everyone. Could a small, inexpensive Covid 'test kit' be created that detects pre-symptomatic Covid in spit? That way more people could add 'spitting' to their morning routine, and they could...

Thanks, phinds. I will try to be more precise.

There has been a lot of talk about the value of beauty in theoretical physics. There seems to be a lot of little things that are beautiful because they make sense, according to what we already know, like the discovery of anti-particles, and recently the Higgs. The standard model was revealed...

Thanks Vanadium 50. Any information will be helpful. The question is not specific to the article, just that i began to wonder how the 'Higgs-into-photon pair' decay takes place in general (before tackling the article) - and to clarify whether such a decay is a direct decay to photons without...

Hi all. I have been reading the following article and have a couple of basic questions about the decay of the Higgs into photons process - https://www.physicsforums.com/insights/lhc-part-4-searching-new-particles-decays/ As i understand this decay - the photons will have the same frequency and...

Thanks, DrStupid. So does that mean when the counter-radiation is taken into account, the actual figure becomes somewhat less than the calculated 2 PW?

Thanks, mfb. So with a totally clean energy source, about 35 times the energy consumption would be possible in theory, before we destabilize the climate from excessive energy release at the surface. That sounds like a comfortable margin. But if that weren't enough, if we had a mechanism to...

Well, we all wear pants and stop at stop signs... :smile:

Ya it's pretty obvious, and the food that we eat also determines how big we should be, so with lots of people around we need them to be mostly herbivore.

The answer should depend on the result. If the result is more of what's going on and what's going up, like pollution, extinction, and temperature, then no, the world doesn't need more power, and the solution lies elsewhere. If we can stop polluting with particles and gassing out as we...

Thanks, Nugatory. That's good to know. I was wondering if there could be a correlation because the electric field of the electron also sort of collapses onto the detector, or a wall, or wherever the electron ends up residing. Also related to the question if i may - I am familiar with the...

A single electron sitting in a void has an electric field that spreads out evenly in all directions as far as there is open empty space to allow it, is this roughly a correct statement? Let's say we now introduce a singe proton into the void, 100 miles from the electron - it will also have an...

Thanks for the explanations. It makes a lot more sense that as a BH diver descends towards the horizon, the horizon would wrap itself around on all sides of you to eventually swallow you, leaving a last rays of universe shining in from a dot above before it closes it's maw around you forever -...

It might have been a discussion on another sight somewhere as i recall. Seemed impossible so i came here to find out.

Thanks, Ibix. I don't recall where it was, but i had read that as you approach a black hole the event horizon recedes away from you, just as the horizon at sea recedes away from a ship. I easily could have misinterpreted what was being said. I'm still wondering how a surface where time stops...
