Quasars, Black Holes And The Expanding Universe

1283 words - 6 pages

So what the heck does a quasar have to do with a black hole? What is a quasar? Highly lit objects in space were recently discovered using radio telescopes. Cosmologists called them quasars, for lack of a better term. They appeared to be quite small, but illuminated the universe around them. To make a long story short, they turned out to be feeding, black holes. Feeding black holes? Black holes eat? What do they eat? Italian food? No, they eat matter and gases that get close enough to be lured in and swallowed up. As the black hole voraciously feeds, it becomes overloaded with gas and blows it out (just like people) causing an immense light. Black holes are at the top of the food chain in the universe. Quasars are simply black holes that are having a snack.
Using laser beam technology at the Keck Optical Telescope Center in Hawaii, the black hole in the center of the Milky Way Galaxy was recently detected. Cosmologists lucked out when a massive, gas cloud approached the center of the galaxy. As it began its journey into the event horizon, or edge, of the black hole, it became elongated and traveled faster and faster. As the black hole began to ingest the gasses, it began to shine billions of times brighter than the Vegas Strip at midnight. The friction created by the swirling molecules caused the bright light. Feeding black holes do not gobble up their food in one mouthful. The gas cloud at the center of the Milky Way is not expected to be completely ingested until mid-2014.
Cosmologists are assured at the center of every galaxy is a preying, black hole, but not all black holes are the center of a galaxy. Some black holes, large and small, wander aimlessly throughout open space. Most physicists agree that any mass nearing the event horizon of a black hole would be sucked in by its immense force of gravity and become decimated. If by some chance the mass did not rip to shreds, it could travel through a wormhole in the center of the black hole and be released through a white hole on the opposite side.

More Holes

Wormholes, hypothetical space tunnels, may not be only at the center of black holes. They could be created throughout the universe by immense gravitational forces that curve the fabric of space. These anomalies could possibly connect two areas of space, two eras in time, or two universes. Science fiction writers of old may have been on to something after all. Beaming people from place to place and time to time may actually become a reality. This concept is completely speculative because volunteers for the trip are not in abundance.
Gloom and Doom

The known universe is expanding. Dark energy is believed to be the motivation behind the expansion. Since 70% of the universe has been calculated to be dark energy, a force property of space, and 25% dark matter particles, a mere 5% is observable, planetary objects. Dark energy and dark matter are hypothesized to exist because the gravitational effects of their presence in the universe...
