The friction caused by the molecular motion causes heat.

According to modern physics, magnetic (and electric) fields are photon fields, therefore magnetic fields are made out of energy.

"A quasi-stellar radio source (quasar) is a very energetic and distant galaxy with an active galactic nucleus" http://en.wikipedia.org/wiki/Quasar You can't disprove this idea, because we have no knowledge whatsoever of alien life forms. I could claim that aliens inhabit the center of every...

Remember, he said 'considered', also, the church dominated at that time, so they were considered crackpots, even if they weren't.

That's right, current does not imply that it is correct. However, the term 'correct' is relative. Think about it this way: when someone formulates a valid unification theory, our Forces will be considered crackpottery, as well as your analogy 'anyone that thought the Earth was round a few...

I may as well provide the standard description. Whether you think it is caused by humans or a phase in the Earth's cycle: Global warming is caused by greenhouse gases, which gather in the Earth's atmosphere trapping heat. It is caused by humans. Options to prevent it: Wait for someone to...

Exactly, you must have a base for speculation, although, not only scientists speculate upon that which we do not understand. As humans, our nature is to attempt to understand that which we do not yet understand.

In what sense? Assuming that gravitons exist, a gravitational field would be an area in which the effects of a graviton would be exerted, therefore, to 'create' another gravitational field, one of two things might happen: The gravitons replicate (?) Some gravitons 'leave' the initial field (is...

Speculation is good, it can broaden your knowledge (although, it can also send it flying out there somewhere). I agree, though, venturing in the realm of the unphysical is good, but understand the one you're in first.

According to the Special Theory of Relativity, going faster than light is not possible, it would require an infinite amount of energy, although tachyons, etc are exceptions. Unfortunately, tachyons were never proven to actually exist, therefore, for now, we can say it is impossible to travel...
