Why there is a galaxy?
A galaxy is a cluster of stars, nebulae, dark matter, and other astronomical objects. Most galaxies are tens of thousands of light years in diameter, and contain billions of stars. Galaxies come in three primary shapes; spiral galaxies are thin disks, with spiral arms surrounding a central hub; elliptical galaxies are uniform, oval-shaped agglomerations; and irregular galaxies have little or no definite structure. A spiral galaxy centers around a hub, which is roughly spherical and bulges outward from the disk. The hub is the gravitational center of the galaxy, and usually contains a supermassive black hole. Surrounding the hub are spiral arms, which are bunched-up waves of stars and gas orbiting the center. The spiral arms usually have more gas and dust, and they contain most of the newly formed stars, which make them appear blue in color imagery. A spiral galaxy may have a horizontal bar passing through its hub; our own galaxy, the Milky Way, is believed to contain a bar.
Black holes are thought to be vital in?
There can never be a galaxy without a black hole. The anti-matter is necessary to cause the matter to spiral. It creates a huge suction.
Does spiral knights cause viruses?
No, its a simple playfull game it has no viruses
Which way do Spiral Galaxies rotate?
Spiral galaxies mainly rotate either clockwise or anticlockwise depending on which way the "winding" started during the formation of the galaxy. Some galaxies, however like NGC 4622 [See related link], can have opposing directions, however this is rare and probably the cause of a galactic interaction.
Explain how sound waves stimulate the hair cells of the spiral organ of corti to cause hearing?
When the sound waves stimulate the hair cells of the spiral organ of corti to cause hearing, the impulses are usually sent to the brain.
Why do paper airplanes spiral?
Airplanes--not just of the paper variety, spiral for all sorts of reasons. Instability may be a cause, or perhaps the aircraft has stalled and entered a spin.
Where are we currently located in the Milky Way galaxy?
Oh, isn't that just delightful! Well, my friend, we are right here on Earth, floating through the stunning spiral arms of our Milky Way galaxy. Just close your eyes, imagine the vastness of space around us, and let yourself be filled with wonder and awe at the beautiful place we call home.
What are the waves that are produced by stars and galaxies?
Density waves (they cause the spiral arms in disc galaxies).
What bone is most common to get a spiral fracture?
In a femur it would be something like a hard landing on your foot causing pressure and thereby creating a spiral as it cracked in an upward motion. In an arm is similar. It takes a lot of force to cause a spiral fracture.
Bacteria are spiral shaped?
Spirochetes are spiral-shaped bacteria.The Gastric HelicobactersSpirilla.DNA?
Are snakes the cause of hurricanes?
No. Hurricanes are a weather conditions. Snakes have nothing to do with it.
Why polio victim suffer from paralysis?
