Re: APOD: Night Launch of the Space Shuttle... (2010 Feb 09)
isn't (very, very) most of these impressive clouds made out of steam (H2O) used do cool down the rockets before take off? If you look at the moment of launch you'll see two clouds, one white, one dirty white in the opposite direction. The white one is the steam, the other is from the solid rocket b...

Re: Distant Galaxies
How long would it take assuming a 1 g acceleration to halfway, and 1 g deceleration for the remainder? My relativity is rusty and my book is in a box, but I think 1 g acceleration would give you less return in velocity as you got closer to the speed of light. I actually did the calculation when my ...

Re: Could Dark Matter Possibly Be . . .
Could dark matter possibly be clouds of extremely small black holes? Atomic particle sized black holes would not interact with normal matter except for gravity. Furthermore, the cloud should be invisible. Why do you say this? Black holes interact normally with matter: they can have an electric char...

1. Are all of these uses vital? You're saying conservation is not even an option here? We have to have the plastic wrappers we quickly throw in the landfills? You're suggesting that because we are currently dependent on such products we must be in the foreseeable future? Escentially, yes. From Mabe...

effort still must be made to reduce our dependence on fossil fuels The problem is that there is no substitute for oil. The US uses five million barrels of oil a day for non-energy uses. Thats almost half. We've been playing with wind and solar for 30 years. They are still more than twice as expensi...

If you eliminate both Downward anomolies (spikes) and upward spikes over the last 200 years, there is a definite warming trend and if it is to a greater extent in urbanized areas then there is a human component that must be included and accepted. I found this chart interesting. It shows temperature...

If this is true, one would have to attribute global warming to cyclical solar fluctuations. http://en.wikipedia.org/wiki/Little_ice_age There is a case that can be made for about half of the current [0.8º C] global warming from 1850 to the present being attributable to a recovery of from "The ...

So he would be travelling faster than his orbit required and would spiral outwards, away from the Shuttle. Vice v...

I am curious how a prism would be used to measure individual star motion in a field of so many star lights. Stars are red or blue because the star's temperature makes the majority of the light in that band. Our star (the sun) is yellow. All stars emit all colors. The spectral absorption lines are i...
