The crater is on the opposite side of Mars from the Tharsis Bulge. The Hellas crater has the lowest elevation on Mars, and is nearly round, suggesting a perpendicular hit. This crater is estimated at 3.9 billion years old, which coincides with new mineral evidence that 4 billion years ago Mars entered a volcanic state as reported in this article: http://news.bbc.co.uk/2/hi/science/nature/4926370.stm I am suggesting the impact which caused the Hellas crater was intense enough to cause the Tharsis bulge and major volcanic activity which created Olympus Mons, and the three other major volcanoes of this region.

I live in MN. I've got some bugs that really creep me out, but I haven't been able to identify them online. They have the appearance of a hairy caterpillar, although they are pretty slim compared to the catepillars I've seen. Brown in color, with a lot of hair. They do have legs, and are super fast. They also seem to not like the light, because if I turn on a light they go scurrying for the darkness. They also have the ability to climb the walls, which creeps me out even more. I'd like to know what they are so I can buy the right product to make them disappear.

Each atom of element 112 lasted only 240 microseconds.

I'd like to know how they could realize the chemical and physical properties of that element in such short amount of time?

The earth, the moon, the sun, the planets, millions of stars and other planets throughout the galaxy share this common shape. Why? Galaxies do not. Many other objects observed in the heavens do not. Asteroids and some of the smaller moons for example are not spherical. Why?

when i was in school, they dont this experament to show that sound travels throu air but thats not what im asking about. to show that sound travels through the air they put a noisy toy (battery opparated of course) into a tank thing and with another special tool removed all the air. you couldnt hear the toy anymore. but still if there wasnt any air in there i thought that the tank would have smashed into its self. because you cant put nothing into a jaqr can you. and if you can techniqy its somthing so that its not nothing!!! anyone explain this please?
