theoreticly they will have no colour what so ever... how ever since without an atmosphere there will be noone to look at the sky this becomes a philosophical question
If gravity suddenly disappeared, the moon would fly out into space in a straight line. If the moon suddenly stopped moving it would fall straight into Earth.
They probally want something!
If argon suddenly disappeared from the atmosphere, it would disrupt various industrial processes that rely on argon, such as welding and manufacturing. Moreover, argon is used in some medical procedures, so its absence could impact certain healthcare practices. However, argon is not a major component of the atmosphere, so its disappearance would not have a catastrophic impact on the overall functioning of ecosystems.
Well you would not be able to get answers to questions like this.
people would get ill and sick
life would follow
You would see things - including Earth itself - break apart.
Well considering the fact that a lot of x-ray and UV radiation from the Sun is absorbed here, a lot of people on Earth would get cancer and other diseases.
we would die
If the sun Sol suddenly vanished, the earth would continue on a straight line; in other words, its orbit about Sol would be over/stopped immediately.
If the sun disappeared, we'd lose heat and oxygen. And without sources of sugar, we'd also have no food source of immediate energy.
Not really. If Mercury suddenly disappeared, it would not significantly affect the rest of the Solar System.
