Say, if the earth were to try to go around the two stars (suns), would that cause problems on earth and for us? And, our moon traveling around the other moon of ours, would things on earth be stable, i.e. the tides, and other environmental things?

I just found out that Potato Chips are packed in nitrogen when they are bagged. Is that healthy?

It doesn't sound healthy at all. I don't think I'll be buying chips anymore.

How would I solve for a line equation if I know it's perpendicular to another line, and I have 1 point?

Example: (this isn't the actual question, I just want to know how one would solve it, so that I can solve a similiar problem. If I just asked for the answer, that wouldn't help at all if I encountered another problem, eh?)

If y = ax + b is the equation of the line that passes through (6, 5) and is perpendicular to the line y = 4x + 3, find a and b

Is the universe an erroneous perception of reality?

Some people believe the universe is an illusion and that god and the big bang and us don't exist! We can say the universe is not exactly how we perceive it to be. But there still has to be a reality behind the illusion or minimally something experiencing it. How do you perceive the universe, real or illusional?

I need help identifing these fallacies.?

In one of her columns, Abigail Van Buren printed the letter of I'd rather be a widow. The letter writer, a divorcee, complained about widows who said they had a hard time coping. Far better, she wrote, to be a widow than to be a divorcee, who are all rejects who have been publicly dumped and are avoided like they have leprosy.

Some christian and other groups are protesting against the placing on federal property near the white house, of a set of plastic figurines representing a devout jewish family in ancient judaea. The protesters would of course deny that they are driven by any anti-semitic motivation. Still, we wounder: would they raise the same objections.

Near death experiences?

Do you think it's possible that what a person feels or sees during a near death experience is explained merley as a consequence of a "biological shutdown" of the brain? Basically what I'm asking here is whether it is possible that those experience are triggered by the brain as the neurons begin to die?

Please stick to the question, I don't need religous types of answers!

Cold starting motor vehicle?

High revving engines on highways like high flow thinner oils but low revving highly loaded engines e.g. trucks like thicker oils due to the bearing loadings.

When I start my car the oil is thicker than it should be for my engine, with the above statement in mind would it therefore be better to keep the revs low and labour the engine more, as the thicker oil would protect the bearings better than the cams due to inadequate flow.
