Photon pair generator?
Does anyone know where I could find a reasonably priced photon pair generator online?

Let’s say the quantum uncertainty which is currently quite small and doesn’t affect our life on macroscopic scale suddenly increased. Magically we are still living in this weird rule of physics. How would we see daily stuff? like how would I see a ball rolling in my sight?
As the title asks, what is the average mass of each kind of cloud? Ignoring things like overcast days, and only considering clouds large enough to identify. Or maybe rather than “average” it’d be better to say “what is the mass of an archiypical cloud of each type?” Eg an archiypical cumulus, cirrus, cumulonimbus, etc.
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...
Where does the sound go to when you’re in a spaceship in 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)....
(To be clear, I’m more interested in the reach and scaling of gravity.)...
I was thinking about vaccines and their usefulness, when it occurred to me that, in using vaccines, we’ve sort of pigeonholed viruses into behaving the way covid does. Haven’t we?...
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....
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...
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...
Also, would it matter if it was the plain-style mask or n95?
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’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?...
Specifically why is it so radioactive for no obvious reason? Why does it not have any known stable isotopes?
