I know that certain things will make the bowel movement more disgusting: things such as boiled eggs and sausage. But what is happening in particular with this food to make it stinkier than others? It seems to be a common thread that the food is high in protein.

I just can't believe the odor that some people can manage to put out: an odor strong enough to cover the entire floor of an office building.

What type of tool and associated pressure would it take to punch a 7/8" hole through a standard 2x4 stud? Ideally, it would produce a single "cork" of wood. Of course, there will be follow-up questions but please take a shot at this one.

It is not faceted but smooth on one side and the rest looks like it might have been dropped because its sort of sharp.It is a deep clear green like a 7 up bottle. Do you think this is all it is? How do I find out? The rocks belonged to a gemologist years ago, he died and someone bought the house and gave us a pile of 'rocks' that were in the back yard. This piece is the size of a huge avocado-it also has some white rock on a spot of it, looks chipped off.

The container is initially empty (vacuum).
The walls are rigid, they are perfect thermal insulators, and have zero specific heat. There is also a small valve.

When the valve was open, the air rushed inside the container with a lot of hissing. After some time the pressure inside the containter became equal to atmospheric pressure on the outside.

Temperature of air in the room is 300K.
What is temperature of air inside the container?

As we all know the Sun is a star, not a planet , and by this conclusion we also know the sun -alike every star- will die, what happens to us then, is the End of the sun, the end of existence, what if Mars get blown up by the super nova the sun is becoming; where we have to go then? Are we doomed? i know it will take millions of years, but still , what happens when the sun becomes a black dwarf , no sun= no life= end of humanity? isn't that cruel? what do you people think about it, if we" would" get to Mars, still we don't have the energy of the sun , so we would die there also. Like does it scare you to know that in a couple of billions years , life will cease to exist?
it seems so unreal? how do you deal that problem, maybe we will be in another universe once an their a new sun will shine?
