According to scientific theory the universe is forever expanding. That is until it reaches its end, when it will then collapse. Physically I wonder what this will be like, as I will probably not be around to see it.

If it were in a movie, everything would probably explode. I on the other hand think blackness would fall as everything is sucked in to nothing.

What are your theories on the subject; and what are the scientific ones if any?

Why doesn't the US start using the metric system when it is so much simpler and quicker than imperial?

1000mm = 1m 1000g = 1kg 1000ml = 1l
1000m = 1km 1000kg = 1t

Whats up 1760 yards in a mile? Surely that's just an unnecessarily awkward number. Wouldn't using the metric system save US industry loads of money in the long run.

My daughter, who I don't live with, was not immunised as her mother, who never consulted me, didn't think it was a good idea. To cut a long story short, I have full access to my daughter but her mother is a control freak and despite convincing herself otherwise, is very reluctant to cede any control of such things as immunisation to me.

When we did finally talk about it, she gave, as her reasons not to, the worry of the triple vaccine that was circulating around that time. Also her boyfriend (she has a child with him too) said that he believed the BMA were in the pockets of the pharmaceutical giants and that immunisations, or at least some of them, were not as important as we have been led to believe.

I would like to hear your views on the MMR and the attitude of the pharmaceutical companies wrt immunisation.

Hi! This is in the section of my trigonometry book on trigonometric identities.... specifically the sum and difference formulas for sin and tan functions. Anyway, the directions say to "Write each expression as a function of α alone." I have no idea what that means or how to do it.

Here's a few examples:

sin (α - π)
sin (360° - α)
tan (π/4 + α)
tan (180 + α)

What does that mean and how do you do that to problems like the above? Thank you so much! I'll pick a best answer TODAY!

As a gift, I was given an old locator's level. It is a steel box tube about 6" in length. It has a level bubble on top. There is a small peephole, and when you look through it, it has tick marks and a horizontal line. I guess it was used by surveyors to check elevation differences, but I am curious how it works.
