Diamonds are hard, but brittle, and not particularly strong. Diamond as a basis for armor doesn't make much sense. Brittleness is bad when sudden impact is exactly the stress being defended again...
Under normal circumstances, monolithic diamond is pretty terrible at resisting impact, due to it being weak in certain planes, also known as cleavage planes. To solve this, why don't we just make ...
That question was off topic for two reasons: There was no speculation. Paraphrasing loosely, this site is about "what if" questions with a foundation in science. It was about history. This is n...
Myself, I think that all sciences are in scope on this site. (We're already barely getting any traffic; artificially restricting scope further probably won't help much with that.) The way I see it ...
A now-deleted question involved archaeology, linguistics, and history. There were some downvotes and critical comments, and the author deleted the question. I don't know whether the downvotes wer...
I've got this idea of a rogue planet that is moving that fast through the intergalactic void that the cosmic microwave radiation, thanks to the Doppler effect, actually provides enough heat that it...
You ask about fluids, but have already shown that this works in air or some gasses. If you are asking specifically about liquids (a subset of fluids), then use the right liquids. You need somethi...
The concept of utility fogs is actually pretty old. The idea is a swarm of fairly small micromachines (about 100 micrometers in length) that would be able to mimic most materials and objects. Each...
The Strawberry Jam can freeze parts in place that don't heat up much. Parts of the trigger mechanism would be a good candidate. So is making the lock stuck in safety mode. Also, you don't have a...
This is not a bug, it is a feature The gun isn't hot until you fire it. That first shot will, due to the trauma, cause the jam to solidify and block the bullet. At the same time, the heat will dea...
So, Second Earth had/has a firearm problem. Since my magic is really just advanced science, I can't create firearm-disabling fields, so instead, I created a spell that should be able to ruin firear...
I assume proper hygiene to prevent post-implant infections, which would otherwise be the biggest risk. Presumably the lab-grown hair needed some hormone(s) to stimulate its growth. There's a chanc...
Should removing all head-hair with laser and planting new lab-grown head-hair on the head be dangerous, especially if done repetitively (i.e. two times or more)? Should it risk someone in cancer p...
If ... Keratin ... can make human hair straighter, is it biologically sensical ... that ... Keratin supplements ... could make ... hair straighter? No. Hair is already made of keratin. People wi...
Some people straighten their head-hair with what's named: Keratin straightening Keratin smoothening Keratin rebonding Keratin treatment It is an external hair straightening procedure in wh...
I speculate that because laser is heat and too much water especially with big/round laser beams can cause injected water to "boil" This argument doesn't make much sense. First, your insides are a...
Many physicians apply numbing agent creams/ointments such as Lidocaine+Prilocaine or Benzocaine+Lidocaine+Tetracaine (BLT) preparations topically some 30 minutes before laser hair removal treatment...
It might be that between year 0 to the industrial revolution (say 18th to common era), the Caspian sea significantly larger than it is today. If so, is there some graphical illustration as part of...
Would it be possible for multiple types of "cancer" cells (or at least host foreign animal cells) to work in unison to create new structures? Normal cancer, inasmuch as there is such a thing, ...
It appears you want to go around a planet significantly faster than at the speed of a normal inertial orbit. That's gonna cost one way or another. Something has to create the downward force to ke...
The search engines see imported posts as duplicate content, and penalize us accordingly. Scientific-speculation.codidact.com is essentially black-listed, and some of that even seems to be spilling...
This is based on a question in Writing about revitalising the community and is pretty much a blatant copy-paste of Monica's answer there. Essentially, it's been suggested that we remove all mass-i...
Imagine a spacecraft in a highly eccentric orbit. Say the craft burns at periapsis towards the planet such that its orbital eccentricity does not change and the craft's periapsis moves with the shi...
How loud is this waterfall, and what extent of deafness are we talking about? Assuming some similarity to human hearing a prolonged or repeated exposure to volume over 85dB can cause hearing loss: ...
Because they haven't yet evolved enough to lose their sense of hearing.
