There’s a good many gravity theories, some that don’t even try to explain the why, only the how and other’s that involve some particle like the graviton. But anyone know if there’s any based on the energetic vibrations of our known particles with mass (those within protons and neutrons)? In other words, gravity’s space...
I know that if an electron collides with its antiparticle, the positron, they annihilate each other and energy is released. But what happens if an electron collides with other antimatter that is not its antiparticle, like an antiproton or an antineutron? Do they annihilate each other too?
I grew up in an evangelical household and went to a Christian school where they only taught creationism (and a little “micro evolution” but not much)....
The following mechanism, by continually creating matter in the universe, if self coherent, would solve many unsolved physical problems : this cosmology would do without a big bang....
I’ve been doing a bit of searching for theories on the origin of baryon matter (including antimatter of course) and some seem to hint at quantum particles spawning from the fabric of space (but doesn’t seem to theorize on how this happened) but not many focus on hypothesizing how all forms of baryon matter ether: was the...
There’s a billion quizzes online that say they can help you choose your first pet, and my 45 minutes of googling before posting this did turn up a single blog that suggested that owners of a class of pet share certain personality traits and lifestyles (although they frustratingly seemed to forget that people own things like...
In digital devices, we have pixels, which represent the smallest unit of size anything can be in a digital program. Something that is a single pixel in size in every dimension cannot get smaller. Depending on the software, though, sometimes their shape is not consistent with one another; a pixel could be square, hexagonal, etc....
Starting from a molecule on up, to cells and beyond, at what system level is a being actually making a decision rather than reacting to their chemical environment based on purely chemical laws? For example, the molecules in a cells are solely reacting to their environment based on chemical fundamentals. However, a person thinks...
I’ve read that at the center of large celestial bodies there’s zero gravity (or close to). While confirmation would be nice, if true, I’m wondering how large that area can actually be and moreover, does it scale up with more mass and/or even size - that is, does the sun have a larger center area of low (zero?) gravity than...
I have heard this mentioned several times with this exact wording, that faster than light travel would break/violate causality and I do not exactly understand why and how it would do that. Could someone more well-versed in physics explain to me why that would be the case? Or is it not the case? (Yes, I am fully aware, that...
So I was day dreaming and I caught a thought. What if what we understand about physics is actually all there is to understand? What if you objectively cannot move faster than the speed of light because you can’t do the time traveling things necessary. This would mean that the only way to travel amongst the stars would be to...
In the famous double slit experiment, setting up a measurement device that watches which slit an electron passes through changes the eventual outcome on the screen, causing the wave function to collapse....
This seems like something that should be true, but I think I remember seeing a Mythbusters episode where they decided it didn't make a difference. That show was more about entertainment than science, so I wondered if there was a more rigorous study done? I've definitely seen splashes of water(?) come out from flushes so that...
I’m having trouble wrapping my head around the scale of the problem of nuclear waste. If we took all the nuclear waste produced in a year and evenly blended it into all gasoline burned in a year would the radiation be deadly? Dangerous? Detectable?...
I love the phrase going down a rabbit hole, but it got me thinking, do rabbits even dig that deep to begin with? And what organisms (besides humans) might dig deeper that might be even more fun to tweak that phrase with?...
I saw that people on the dark web would sign their posts with a PGP key to prove that their account has not been compromised. I think I understand the concept of how private and public keys work but I must be missing something because I don’t see how it proves anything....
Like many, when I heard about Folding@HOME and how I could contribute to the fight against COVID, I put my hardware to work. Now that’s it has been a while, what effect did those projects ultimately have on the outcome? Did it actually help with the creation of vaccines, or was it effectively just a massive waste of energy?
