Sweat and other fluids produced by intercourse are going to float around uncontrollably, and all that salt and moisture could interfere with the electrical systems of a spacecraft. Unless you want to risk a short circuit that can kill the entire crew, it's best if you just ...

In 1915, Albert Einstein figured out the answer when he published his theory of general relativity. The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetime. That curvature is what you ...
Callisto is unique among the planet-sized objects of the solar system in its absence of interior forces to drive geological evolution. The satellite was born dead and has remained geologically dead for more than four billion years. [#paragraph4]Ganymede, another of Jupiter’s satellites and the...
Why do objects float in liquids denser than themselves? When a tire bursts, the air coming out is cooler than the surrounding air. Explain. Why does the core of the Sun contain more helium and less hydrogen than does the surface of the Sun? A. Helium condenses more easily so, when the...
We say of objects or people that they mean so much to us. There’s no point asking what exactly it is that’s meant. It’s a meaning without words, that’s only apparent in the dried-up words that remain after it’s gone. But it survives in the wordless things that will always,...
Why are objects that fall near Earth?s surface rarely in free fall? Why do we have spring and fall? Why is the law of universal gravitation important? Why is there a magnetic field in Mecca? Why is the troposphere thicker at the equator? Why is the Earth's inner core solid and the ...
There is a name-to-object mapping, with the names as keys and the objects as values. Multiple namespaces can use the same name and map it to a different object. Here are a few examples of namespaces: Local Namespace: This namespace includes local names inside a function. This namespace...
at the temperatures of the outer solar system, ice on the surface is nearly as hard as rock, and behaves similarly.Ice on Callisto does not deform or flow like ice in glaciers on Earth.Callisto is unique among the planet-sized objects of the solar system in its absence of interior forces...
That’s led some scientists to actually discuss human colonization of Venus’s high atmosphere, building “cities designed to float at about fifty kilometer altitude in the atmosphere of Venus.”8 When I asked Musk about Venus, I was surprised to hear him actually suggest that the planet ...
