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...
Effectively what the title says; What would different observers experience while travelling through / seeing one travel through the tube, and how could they be used to cut travel times? (Just answe...
Yes. All plants require free oxygen, and any (part of a) plant that is not actively photosynthesising has to obtain its oxygen from its environment. We owe our oxygen supply to the fact that, on a...
I'm spitballing a story where the main character goes through a monstrous transformation. Part of the conceit / my enjoyment is that she's an oncology researcher and will be tracking the transform...
The known charge-conserving decay modes of free neutrons all involve the production of a proton, an electron and an electron antineutrino: $$n\to p^++e^-+\bar{\nu}_{e}$$ This beta decay is why, out...
In my story, I have a small extended family of 30 to 40 individuals ranging in age from 0 to 50 who are on the run from Chinese and Japanese forces in 1400AD. No place in Asia is safe for them. By...
Quantum Computers are considered a more powerful type of computer than so called 'classical' computers. While a typical classical computer could be considered as a black box that can solve Polynomi...
Atmospheric dust by itself shouldn't have any major impact on generation or distribution of electricity. The two are unrelated. However, a fraction of the Earth's electricity production is based o...
It's different for every person. There won't be any guaranteed method that operates on human psychology (without magic). If you keep them for long enough then one effect might be Stockholm Syndro...
How would competitive wrestling change in a microgravity environment?
On Earth, solar flares can lead to displays of the aurora that are both more spectacular and visible farther south. Flares in September 2014 led to the aurora being visible in Maine, which is arou...
I'm going to take one of your examples here: the desert planet. Is that realistic and plausible? It turns out that it is realistic. Wikipedia describes a desert thusly: A desert is a barren area...
