~ WATCH NASA LIVE 24HRS A DAY Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. That's relativity." Albert Einstein Its one of those splendidly indolent mornings. You wake up and your house-the entire world- seems utterly still. Its a day made for leisure. The newspapers waiting on the stoop, and soon fresh coffee is in the pot. The sun, still low in the sky, is just beginning to clear those trees and cast all it touches with a soft glow. Amid the days comfortable hush, your corner of the cosmos seems becalmed. For once, it appears, there is absolutey nothing going on. But in fact your surroundings are positively seethng with activity. The light rays that illumine those headlines were produced millions of miles away, by nuclear fusion on the surface of the sun and they are slamming into your paper at some 186,000 mps. Due to the chemical differences between newsprint and ink, the pages relect most of this radiation whereas the type absorbs it, producing patterns of alternating light and and dark regions. Lenses in your eyes turn those images upside down and then send them thru a series of nerve cells to the back of your brain, where those peculiar sqiggles are interpreted as words and letters. The cat meows, You hear, because atoms in the air collide with your eardrums at hundreds of mph, But even without sound, the air in the room writhes restlessly, rising as its heated and falling as it cools, following the same cyclic convection pattern that , in the great outdoors, forms thunderstorms. Meanwhile, your body cells are burning a simple sugar called glucose, which helps keep your temp near 100 F. A powerful drug in your coffee-caffiene- is speeding to your brain, prompting the release of a chemical stimulant called norepinephrine, which constricts blood vesssels and makes you more alert. But alert or not your not aware of the torrent of radiation that are streaming thru your room- because your eyes only detect a tiny sliver of the electromagnetic spectrum. Your warm cup of coffee is bleeding heat into the invisibly, by emitting infrared radiation. Equally invisible radio waves-from the sun and from elsewhere are piercing the walls, ceiling and even your body. Although you think you may be sitting still, Earths spin is actually moving you along at hundred of mph. Your racing around the sun at about 18 miles per sec while the solar system is spinning trough our galaxy at 140 mps-more than half a million miles an hour. All of this of course, as the universe is expanding like a rapidly inflating balloon.
