The moon-hoax theorist Bart Sibrel is a little weird, but his short films of the great astronauts of past (Neil Armstrong, John Young, etc.) are really interesting because they lose their tempers. I have NEVER seen them do this. What are your thoughts on seeing these great men 'lose it' a little? Was it kind of a 'novel' thing or interesting for you to see? (I know they were justified in getting annoyed).

I have some queries about dominant and recessive traits in genetics, can anyone help me?

Using pea plants as an example. Characteristics of an organism is determined by a pair of factors. If the two factors are different, only the dominant will show effect.

1) Regarding the pair of factors, is one from each parent?

2) And also, is it possible that the dominant allele is the trait for shortness? Cause it's often said that T (tall) is the dominant, and t (short) is the recessive... can it be vice versa?

is this capillary action? what prevents this from being used to produce energy?

i made a cup of coffee by putting a little coffee in a paper filter and putting it in a cup of hot water tea bag style. i left it overnight, about half full, with the top of the filter just hanging over the lip of the cup to keep it from slipping in. as you may have guessed (but to my amazement) the cup had emptied all over my desk by morning.

If Gravity was 'Reversed' for only 10 seconds ... how would life change?

Meaning instead of all matter being pulled towards the earth if for only 10 exact seconds all matter was repelled from earth, how dramatic would life change on earth. The cars, people, homes, trees, and yes oceans would start to head towards the upper skies only to then be brought back crashing onto earth. I think less than 1% of the population would survive, with calamity everywhere. I had a dream and sadly witnessed all this, and it scared the life out of me. But it did leave me wondering if a passing asteroid or meteor shower could actually affect earths gravity for only 10 seconds to destroy manking like this. All answers would be appreciated. trust me they would
