I have this theory about the universe. I think that it cant really end, because the universe itself needs to exhist in space. Like if you have an object, it exhists in space, in air. Do you agree with this perspective?

A triangle is scalene, does not contain a right angle, has integer length sides, and its area is an integer.

Find the triangle with these properties with the least perimeter.

(By the way I found a formula to work out the area of a triangle without knowing the height - sqrt[s(s-a)(s-b)(s-c)] where s is the semi-perimeter a+b+c/2.)

Thanks, a best answer will be voted for!!

I know it's far off, but I am fascinated by human nature to survive. In 4-5 bil. yrs the Sun will run out of energy destroying our galaxy, and changing it forever. What will we do to survive? should we start focusing on technology that can be used to move humans off of earth.

Only reason.. my 21st birthday is Friday.. can I just not take the pills on that day or is it really important to take them?

Their are a couple of twins I know and a few of my friends and I were discussing them.

I know that if two twins came from seperate eggs that were seperately fertilised then they are just 'siblings sharing a womb'.

Now, if they are both from a single fertilised egg that subsequently seperated they have 'identical' DNA. Is it possible that they may still look slightly different?

The twins I know look too much alike to be non identical but they can just about be individually recognised; especially when they are next to one another.

So are they still identical?

Also - while I'm here - some of my friends maintained that identical twins could be different sexes. I just need conformation on this. If two people have identical DNA then they must also both have XX or XY chromosomes so therefore they MUST be the same sex. Am I right?
