Wouldn’t grow something from the inside require a very strong force to “move” the already present one? Instead growing from the last “layer” towards the outside would require a lot less force, but perhaps a lot more matter....
Just a thought, if an event happened well beyond the observable universe that caused entire galaxies to be destroyed radiating from a point source event, what would it look like from our perspective and how close could it get on our observable horizon while still being unable to reach us due to expansion of the universe?...
We know that light and even gravitational waves propagate at the speed of light....
I unfortunately live in a very polluted area, one where air quality apps mark in red and recommend that I never get out of my lair....
This is something I always wondered because some people have a bunch of theories about whether your head should face north or south or whatever, because of the earth magnetic field. Is there any science in this or just “superstition”?...
So, I’ve been reading about the MIT bio suit. It’s basically a pressurized helmet and gloves, and a fancy fabric suit with bands that squeeze you with enough pressure so decompression doesn’t kill you....
Mars influence on the Milankovitch cycles:...
Sounds like a stupidly easy question to find out with a quick internet search, but it’s not....
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 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....
“Stronger” hearts typically have a resting pump rate lower than that of weaker or less healthy ones. A healthy, athletic male might have a resting BPM of 60, while an otherwise healthy but post-partem female could be closer to 90....
I came across David Sinclair and his research into reverse aging. Especially, I came across this video by Veritasium with Sinclair. Apparently his team has managed to reverse aging in mice in a lab? Has this been peer reviewed?...
I thought that the frequency of light was directly inverse to the wavelength by a constant. In other words, I assumed that graphing the frequency of light as a function of wavelength would be a straight inverse line. Because of that, the graphs for the distribution of light from the sun as functions of frequency and wavelength...
Seeing as the heat death of the universe occurs once black holes have stopped emitting Hawking radiation, and BH’s life spans are tied to their mass, could a (very, very advanced) civilisation bring two or more together? Assuming nobody’s succumbed to proton decay before then, of course....
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?
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?...
Okay, so I know this might be a bit hyperspecific, but I don't know where else to ask it. I'm working through a microbiology lecture, and the professor says the the B strain of E. coli has a tRNA suppressor that allows it to transcribe phage genes that have any nonsense mutation. That seemed a bit vague, so I decided to look it...
Asking this because I’ve been thinking about resin printing and how a small layer of said liquid could, in theory, be used to make the prints faster and negate any problems regarding the FEP film (which can wrinkle, tear and be a hassle to clean when small pieces are stuck to it). The ideal liquid would have to be:...
Since we know that it isn’t constant with time, how can we be sure that it is constant with space? This might be a reason the variability in our measurements which seem to disagree....
