What is the atmosphere of the moon made up of

The moon is considered to be surrounded by vacuum. The tiny amount of gases near the moon is almost zero compared to the atmosphere of Earth - less than one hundred trillionth of Earths atmospheric de

With use of current technology, what is the "maximum range" at which we can detect exoplanets

As I understand things, 1.) The technology to detect planets of Earths mass doesnt yet exist. 2.) There is a limited range at which the current technology will work. e.g., we can only use this tech

Can matter exist outside of dark matter

I saw a documentary saying that dark matter is kind of like a skeleton where matter clumps together.But can matter float on freely without its counter part?-The majority of the universe is made of so-

If astronauts put a open can of Mt.Dew on the moon how long would it take for ants to build a space shuttle

I think a day.-Just as long as it would take to fix a flat bicycle tire.-They could never reach space, and not just because of there incompetence to rationalize and think logically. If I was to hypoth

The Big Bang theory of the formation and expansion of the universe is supported by the observed what

A) Blue-violet shift B) Red shift C) Big crunch D) Shorter light wavelenghts-B)-red shift of galaxies.

Do dark matter interact with itself

If so, why does it not clump up like galaxies? Also, if they do not interact with itself or regular matter, what keeps it around the galaxies?-The words dark matter are just place holders. That means

What are extra-dimensional beings

alien, creepy stuff-Science Fiction.-Things like Mr. Sphere in Flatland, if we are analogous to Flatlanders. I assume thats what people mean, but its a wooish, fluffy term. Generic New Age mumbo-jumb

According to the Big Bang theory. How exactly was antimatter created

Antimatter and matter were brought about by the same same process that got the Universe started. However, it appears that may of been just slightly more abundant. The few few milliseconds of the Unive

What colour is the sky

for the people on the earth it appears blue due to atmospheric refraction but for the astronauts in space it appears dark as atmospheric refraction is not promonent in space..-It is a trick question.

Why do we even guess at the total "mass" of a universe

When its thought that we can only see a few percent of it anyways? Are we assuming translational symmetry and assume that its same everywhere, even places we cant see?-We dont guess. We experimentall

When is the next "waxing moon"

And what exactly IS a waxing moon? My mom wants to know, dont ask me why-As others have said, the waxing moon is when it will be growing.So it would be after the next new moon.The next new moon is May

Our nearest star is a black hole?

I heard when a stars life comes to ends, it becomes Dark hole. Sun is also a star. If Suns life comes to ends, will it become Dark Hole? If so, Will it suck nearby planets like Mercury, Earth? Sorry

What is the most advanced piece of technology on Earth at the moment

I was waiting for the Cold Fusion to happen to blossom as technology. LHC is a one of a kind, whereas Technology should be one integral piece that is repeatable. Though old the Space shuttle is the mo

Should the astronauts that claim they went to the moon be interrogated with a lie detector

No,just check their foot prints.-Lie detectors arent always that accurate - theyre approximately 94-95% accurate, in perfect conditions. However, someone being interrogated is going to be nervous, and
