Everbody in this section probably knows that 2 Hydrogen nuclei (protons) combine to give Helium.

However, although the atomic no. of He is 2, its atomic mass is 4. So where in the reaction do the 2 extra neutrons come in.

Do they arise from protons with electrons stripped out? Then what of all those free electrons, are they just lost as beta particle radiation?

The fact of the matter is embryo/foetus are living humans. When a human takes human life for any other reason than to defend themself or another, from (physical) harm from that human, that is murder.

To predict the future of the 'unborn' you would have to be a clairvoyant. Am I to now believe pro-choicers believe in spiritualism.

Sex can equal pregnancy 'human life', we all know that. Ignorance such as society falsely taught condoms alone are enough protection to prevent pregnancy, help fuel reasons for murder. Just as death can't be revesed, life can't be reversed on demand. The way it's done is through murder & that is unacceptable. The society that life will be born into is irrelevant, as life prevails.

I have heard many refer to abortion as emptying ones uterus. Once the life has been murdered, I agree that they are just emptying their uterus. But to get to that point they have murdered or payed another to murder.

Shouldn't humans have evolved beoyond this by now.

Scientist believe that the universe we live in is expanding. The big bang could have been formed from a black hole that imploded from another universe. It would explain the cosmic microwave background and the expansion of the universe. When the black hole in the alternate universe imploded it essentially created it's own space and time. This is just a theory but tell me what you think.

It's really strange--out of nowhere I sprained my leg last week; my leg just seemed to weaken without me doing anything that would normally injure it. After that happened, it seemed like everyone I talked to had also injured their muscles right around the same time--people were limping and saying, "I don't know what happened, I just got really sore a few days ago." Even a few movie and TV stars were reported to have sustained injuries last week.
Does this have something to do with gravitational pull, or what could explain this phenomenon?

some examples: bridge supports that will prevent a catastrophe when one component fails... a predator/prey relationship in an ecosystem to control the population... checks and balances to theoretically control the power of a government...

does a system need a way to regulate itself to perform its intended functions properly? how long can a system without these safeguards built in operate at all?
