When we launched this community, we did not yet have the ability to set different reputation grants for different categories. We've had this for a while but we failed to follow up before now, sorr...
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 ...
For the sake of a fictional story, you should be thoroughly aware that the author is playing as a god. The laws are what you want them to be, and what you say happens is what happens. I am not awa...
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...
There are multilevel automated food plant farms in existence that are artificially illuminated. Sure they may use skylights but they have many times the growing area so the plants are not getting ...
Neopanamax beam is just under 52m, with a height of just under 60m. Let's give it about 50% margins on each side, and that give you 100m between bridge supports. A suspension bridge with a 100m spa...
"How would" has no answer The question "How would wrestling change" is unanswerable. There are many different ways in which a sport could change in a new environment. As with most sports, "wrestl...
Express mtDNA-specific cytidine deaminase in oocyte mitochondria. Mitochondria are cellular organelles which, among other things, convert hydrocarbons like glucose into fuel that the cell can use,...
In most quantum field theories$^{\dagger}$, we have a quantity called the Lagrangian, from which we can derive information about the behavior of our system. It consists of a number of terms represe...
What you are asking for is unrealistic. 3000 kg is huge. That's over four times the mass of a typical rhinoceros, for example. Being really large like that lets it bully its way to some other ani...
Yes. By restricting the directions it can travel in, you can create an Alcubierre drive that can't be used as a time machine to create paradoxes. The simplest way to do this is to pick a single fra...
Idea 1 Everyone needs water. Your Giant Hyena frequents watering holes and waits for prey to arrive. Maybe it camoflages itself with mud or lurks underneath the surface of the water. Once a target ...
How does this time traveler handle the risks of being infected with a contagious idea then spreading it to his fellow humans on return to his own time? He doesn't. Coming back with a revolutionar...
Yes, it can – they're called “heterotherms”. As with most "can an organism" questions, you only need to look to find some organism that already does this. All hibernating animals (many bears, many...
Any mechanism for generating a neutrino beam starts with a way to generate neutrinos, and there is only one underlying means right now: weak decay (including beta decay in radioactive nuclides). Th...
No way would I buy that thing. ...ok so the details really do depend on exactly what it does. 1% of my revenue for 10 gizmos? And I'm the CEO of Intel? Intel made between 10 and 100 billion dollar...
One obvious answer is RFID tag microchip implants, for example attached to the ear at birth, at the same time as someone is given their personal credentials. The body can change but the chip will r...
Because they haven't yet evolved enough to lose their sense of hearing.
Cox & Loeb 2008 performed one of the few simulations of the Milky Way/Andromeda collision of which I'm aware. It's not particularly easy to simulate a galactic merger, so the lack of detailed n...
The planet will instantaneously explode. The Earth has a gravitational binding potential of about $2.25\times10^{32}$ joules, or the weekly energy output of the Sun. This energy also currently be...
Yes, for a given definition of 'North Pole'. You see, there are three different 'North Pole's Geographic North Pole, which is defined as 'the point in the Northern Hemisphere where the Earth's a...
Yes, if the orbit isn't circular. Seasons can definitely occur on a tidally locked planet. Just like normal planets, tidally-locked planets don't need to have perfectly circular orbits. This mean...
Tidally Locked and no Axial rotation are not quite the same thing. A planet with no axial rotation would not have a habitable zone. No rotation means that it will experience a day/night cycle as ...
How small of a thing can we see on the moon? Wikipedia has a list of objects on the moon that can be visible with unaided vision. Doing some poking around Astronomy blogs for real-life experience ...
TL;DR You'll see the development of both aerial vehicles and the means to survive in harsh spaces. Technology will develope faster in this world - at least, technology related to this mountain. A...
