Low gravity golf was invented by Alan Shepard in 1971 when he hit two golf balls 40 yards on the moon. Surprisingly, this version of the sport with little atmosphere and much lower gravity, is the...
I was investigating a few ideas on recreational solar sailing, and came up with some interesting things - The primary equation in solar sailing is $ F = {{2 R S A} \over {c}} \sin^2{\theta} $ Whe...
I recently learned that it's believed that the solar system once had one more gas giant, which was ejected by Jupiter some time in the past. https://thesolarsystem.fandom.com/wiki/Fifth_Giant Doe...
The Earth-Moon Lagrange points have names: L1, L2, and L3 are Libration Points, the L4 and L5 points are the Kordylewski Clouds. The Jupiter-Sun L4 is named the Greeks, and the Jupiter-Sun L5 is n...
What happens if Earth's magnetic field shuts down? How exactly does this impact humans, and how long before we need to make significant changes for survival? Does it make any difference if Earth'...
How about "rigorous-science"? There are lots of ways to apply rigorous logic to a question, this draws focus to the science part.
Yeah, that's my fault. I wrote up an answer and posted it, but I deleted it shortly afterwards (and later undeleted it . . . and then redeleted it). I did so because I've been extremely active on S...
Of the suggestions I've seen, I like 'scientific worldbuilding' the best. However, Mithrandir has raised some concerns that this focuses on the worldbuilding aspect, on a site where we're inviting ...
I was the mod who deleted the comment - thanks for bringing this up. The main reason I deleted it was that I figured that the comment was primarily for the benefit of the poster, rather than the co...
I would think that, at the very least, [science-based] is implied by this site's scope and doesn't add anything. (I didn't think to ask for it to be stripped on import, but presumably it's not har...
Hi, I'm new here. Well, new here specifically. I joined SE almost 9 years ago. I would rather hang out here than SE because the QPixel license is AGPLv3 and it seems we are in the process of for...
Interesting question, Sleipnir approves. The short answer is, it sort of depends on your creature's body design. From the reading it sounds like you are describing something that would function s...
Given the example of the development of the scorpion, it started out as a segmented worm with a pair of legs/swimming paddles per segment. These legs later developed into a variety of appendages, ...
There's at least one paper suggesting the reason for four limbs is because of the way embryos develop. Basically, an embryo's cells develop early on into three layers: ectoderm, mesoderm, and endo...
I would say yes. There's already a real-world element that does at least the first three and its name is uranium. Naturally occurring in the universe, rare though. Yep. In fact it's one of ...
When we did the initial import from Worldbuilding SE, we also inherited the tag set from there. This leaves us with some tags which are (should be) redundant on Scientific Speculation. I primarily ...
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...
I once had a question Somewhere Else about an economic stipulation and how its imposition would affect the world. I didn't think it to be a good stipulation and expected to be skewered by answers p...
Any volume is large enough for rain or fog. Humidity buildup (rain) is a concern in spacecraft design, and was one of the reasons (too much rain) that caused one proposed Martian settlement to fail...
For those who don't know: while this site was being proposed, I raised some issues about not importing questions with the [magic] tag. After some discussion, I feel like we reached a consensus that...
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...
Two months ago the question was asked: Do we want to keep the [science-based] and [reality-check] tags?. A month ago the same user asked: Are there tags we should remove from all questions...
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, ...
I have some interest with this site, but if I want to ask something, I'll need to properly figure out if it's suitable to post it in SciSpec CD. Considering that this site is different from a site...
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: ...
