In fact following, understanding, him helped me clarify my own views. Which is something I imagine he'd like. Still his personality is very unsuited to politics or high public exposure.

I visited this lab in college. One of the most amazing things. I wanted to add some details. The detector is actually tons of little cells, filled with the liquid which creates a blue lights when a neutrino hits it. The neutrino beam actually has two particles, as it travels, it splits and there is another lab being built to detect these that split from the straight beam. The cell detectors use fiber optic cables to detect these tiny blue lights and all these cells are than mapped out. I asked, so how do you know that the particles and neutrinos and not something else. We don’t know, just that it is far underground so limits possibility of most other stuff. Now, out of these trillions a second, I believe it was something like 1 or 0 neutrinos get detected per day. The amount of neutrinos detected was very low. Now the following is my own opinion and I am not physicist: we don’t actually know what these are or what is being detected, these theories aim to describe a natural phenomena, that is the extent of its truth.

It's fun to see these two communicating with the same dramatic pauses and inflection that they use in their videos. Kind of like Siri and Alexa having a conversation, except more entertaining.

A universe full of photons isn't exactly nothing. It's nothing _useful_ but it's not nothing. So the philosophical question "why is there something rather than nothing" was deliberately twisted here for there to be a scientific answer rather than a scientific ¯\_(ツ)_/¯. And while this might feel more satisfying on a surface level, I honestly hate it when people do this. It's imprecise, it muddies all sorts of waters and it's honestly a style of science communication that usually not to exhibit is a big part of what makes this channel so amazing to me.

I know this is a case of Dunning-Kruger effect, but I always thought that the question why there was more matter than antimatter would be neatly explained by something resembling the bubble universes. What I mean is there is a random fluctuation in the matter/antimatter ratio in any given volume of space, but the “global” ratio would still be 1/1. We just live in a local bubble that happen to have the ratio marginally to the mater side, but because of the inflation and space-time expansion we would be never able to observe other more balanced (or even anti-matter heavy) patches of space. I know this is untestable /probably/. Also, I know that people who actually have years of studies and published papers on the subject must have entertained that idea (because, despite my mammalian instincts to the contrary, I am not the sole person capable of coming up with that), but I've never heard it discussed or proposed - please do tell me, why is that so. Is there some obvious /obvious to astrophysicists/ reason why that idea is pure nonsense, or is it just too speculative and philosophical in it's nature that it's not really worth being talked about, or maybe something else?

@Vasharan

4 жыл бұрын

IANAAP, but if there were clumps of matter clouds/clusters/galaxies and antimatter clouds/clusters/galaxies, we should be seeing more gamma ray sources when they run into each other. And we have seen many examples of galaxies that have collided or will collide or were involved in a past collision. Now one could argue that perhaps a matter/antimatter split happened early enough in the history of the universe that cosmic inflation spread the matter and antimatter clumps apart, but we can also look for primordial gamma rays and use that to establish lower bounds for this hypothesis. AFAIK, there aren't many proponents of the hypothesis that there are equal parts matter and antimatter in our observable universe.

@BitJam

4 жыл бұрын

It is extremely improbable (to the Nth degree) to have such a large clump of mostly matter only because of a statistical fluctuation. It would be like flipping a coin N times and have it always come up heads every time where N is the number of particles in the Universe. Might as well say "God made it that way". Yes, if you have a large enough meta-verse to form the bubbles in then it's possible to have such unlikely bubbles but you would still need to explain why were are in such a very unlikely part of the meta-verse. Almost any weird experimental result could be chalked up to being an extremely unlikely statistical anomaly but saying that is basically giving up on science. It's more fun and interesting to see if there is a less unlikely explanation.

@FunkyDexter

4 жыл бұрын

BitJam that is not what he is saying though. Due to the expansion of the universe, the ratio between matter and antimatter interacting at the time of the Big Bang needed to make our universe possible is very close to 1. So even an extremely small fluctuation in an inflating universe would produce a bubble. And I think this concept is actually explored in inflation theory but I'm not sure it is been taken in account very much.

Certain nuclei are more prone to interacting with neutrinos than others.

Argon-40 is a susceptible nucleus that requires no purification, is common and can form a liquid through which signals can travel easily.
