Advertise on Gab Gab.com is an environment where very little advertising is happening (so what you spend will be visible), and the audience is almost completely people actively looking for alterna...
You have mass flow rate and velocity, but the area this is spread over will say a lot - $$\dot{m} v = F = 1 {{kg} \over {s}} \cdot 1,000 {{km} \over {s}} \cdot 1,000 {{m}\over{km}}= 1 \times 10^{6...
I don't see a Facebook page link. Any other social media. Simply having a presence there will give some people more trust. Occasionally making a post when a new forum or feature is enabled would...
So couldn't earth be odd shaped other than a sphere? No. Something the size of the earth has significant gravity. There isn't material strong enough over large distances to result in anything mo...
The shape of the Earth is mostly a result of its gravity pulling its mass into the most efficient shape available. The oceans are also pulled towards the centre of mass, and collect on the lowest ...
Your intuition is correct. Let's suppose that at STP, a human needs to breathe 1L of O2 in 200 minutes. That's 1.43g of gaseous oxygen. If the pressure is raised to 5 bar, a human still needs 1.43g...
Years ago I read a letter in a magazine suggesting a method for reducing the fire risk in an enclosed environment such as a space shuttle. The idea was to reduce the oxygen concentration to the po...
Imagine a far-future spacecraft drive that accelerates its reaction mass to a small fraction the speed of light (say, 1,000 km/s). Say the mass flow rate to the drive were 1kg/s, and say the reacti...
The issues here are largely the same as with the Outdoors site, including the imported content. My answer to your question in Outdoors mostly applies. A few differences to note: The recent rash ...
Codidact's communities have a lot of great content that is helping people on the Internet. Our communities are small, though, and sustainable communities depend on having lots of active, engaged p...
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...
Kind of depends on whether you mean water as in H2O molecules or water as in state of matter = liquid. The amount of liquid water will naturally vary a lot depending on seasons and warmth. We know ...
It seems that what is now the earth started as an aggregation of rocky material. Large amounts of water were then added by bombardment of comet-like bodies. These contain a lot of ice.
Is it plausible to assume that the total amount of water (edit: water molecules) on planet earth was, in different periods of earth's history, significantly lower or significantly higher, or rather...
It seems you want to "store" energy as light by keeping it bouncing around inside a chamber. No, that's not going to work, at least not for more than a few 10s of nanoseconds for a chamber the siz...
The way this would work is by creating lasers & pumping them into a chamber where it can't escape. The power for the lasers to be created is made either with a generator or by charging using an...
An average human masses 60Kg. The largest bird ever to fly, Argentavis, massed about that much. https://en.wikipedia.org/wiki/Argentavis So it seems reasonable that flying creatures the same weig...
Define every single human by their own phenotype, generation and breed. DNA analysis has a price but it's not too expensive, childbirth has never been cheap afterall. This way your identity is ba...
This is probably impossible, but your question leaves off necessary detail to know for sure. If the point is to be able to glide for "a few minutes" after jumping off something tall, then we need ...
I imagined a person who's scapulae is overly developed and extruding outside the shoulder girdle like an elitra or fixed plane wings. They can be moved by shrugging the shoulders or rotated by rai...
I distinguish human-identification from bureaucracy-applied-to-humans: There was a period in human history in which no state existed so no bureaucracy-applied-to-humans existed and humans identi...
There are two parts to your question. Humans can certainly continue to thrive on earth whether sea level rises or not. We live in quite a variety of climates now. Some climates shifting more tow...
If humanity will cause natural dissolution of all ice in planet earth's poles and the sea level would indeed rise tremendously all over the world --- would it be justified to try to "reverse" the s...
The first question is: What is instantaneous speed measured against (that is, what is the “ground” relative to which the speed is measured)? Remember that there is no such thing as absolute speed. ...
You would send out a small laser or radar retroreflector out of the side of your ship and observe the tracking angle. Knowing the speed of your marker you can calculate the speed of your ship with...
