... Also, the velocities of collision are quite high. ... The higher the velocity, the higher the kinetic energy, and the more heat generated ... In reality, the velocities are much higher, resulting in a heat energy more than ten ...
... had a totally bogus article about a "chaos cloud" that was going to doom us all ... mass of 7 tons, and at an impact velocity of 16 kilometers per second (the speed of ... But it does so while it is still very high over the ground, 50 miles or so. ...
... the sky are in constant motion, and some move with an incredible intrinsic velocity ... objects in the catalog were a group called ``spiral nebulae'' (nebula means cloud ...
... There are bits of dust and gas in space, and at highvelocities (faster than light!) they pack quite a wallop. ... no bigger than a grain of sand if the relative velocities are high enough (though there are other, more complicated effects ...
