I thought black holes, where light couldn’t escape, was found to emit neutrinos(weak force?) which showed up in some deep underground pool as they traveled through earth. Being the escape velocity to leave a black hole would be faster leaving than light coming in.
How do they know they (neutrinos) are moving and not just blinking like a xmas bulb on a string of lights where it only appears to be movement?
Now, about tunneling out of a blackhole ~ once you do that trick you're out and you take off at the speed of light ~ which ain't that fast all at once so they'd be stretched out like crazy ~ very long wave phenomenon. Get a few thousand miles away and they'd shorten up tight ~ the speed of light would be the same in all cases.
Now, about neutrinos ~ according to the little brief at Wiki, neutrinos interact with the WEAK FORCE and GRAVITY ONLY.
They mediate the fusion of hydrogen in stars ~ (and probably the fusion of hydrogen with other junk in the corona of stars but I couldn't find anybody who claims that yet ~ Widom and Larsen et al do claim fusion occurs in the corona but haven't pinned down what that means in terms of all possible interactions.)
Good questions. BTW, I've been following what our more scientific brethren are into for most of my life. They promised FUSION ENERGY which would produce electricity so cheap you wouldn't need to meter it.
They didn't.
But I try to keep up. A lot of this depends on a fairly good grounding in mathematics ~ mostly in the orthography but also in the structure with stuff in motion through time. A good deal of it also depends on 'speriments ~ unavailable to most of us so I've always found it useful to know some professional physicists who have engaged in 'speriments and they can explain it ~ which they do along with a whole lot of other stuff they think you need to know.
Fortunately I live in a community that has professional physicists and scientists around. You do know those guys have a pretty high burn out rate. You go from grad school to a project, and you last through that project until it completes, or leads to something else, and if it falls through ("numerous blue laser" projects fell through) you are kind of out of the field. Seems like a waste of good talent but right now we have plenty of spare physicists.
The internet is fairly comprehsive and has all sorts of really great instructional materials. There's no reason someone with time on their hands can't develop a fairly decent understanding of the four fundamental forces. You can quickly develop more intelligence than was available to anyone 50 years ago, and maybe even more than was available 10 years ago. Just stick to it. Maybe you too can build a new home heater that runs on dirt and leaves.
