I doubt that energy not being created is not a possibility .. notice that I included doubt in that doubt.

Re: Rusians plan base on Phobos

The article says the Delta V to Phobos, land, and return is 80% that of a earth to our Moon and return .. so it must be much higher to land on Mars and return. A huge advantage of operating Mars rovers from Phobos is far less time delay (20 minutes Mars-earth). Ah, but they don't tell you the delta...

Re: Is there a mathematical symbol for 'Now'?

Your t=0 strikes me as no time, so no 'now'. Not at all. Since time specifies intervals (an isolated point of time is meaningless), and since time flows at a constant rate (the interval between t=0 and t=1 is exactly the same as the interval between t=5 and t=6), the choice of reference value is ar...

Re: STS-127 and ISS Expedition 20

When the Soyuz spacecraft docks with the ISS on 5/29/09, the ISS will have a crew of 6 for Expedition 20 and all those after. When STS-127 Endeavor flies, scheduled for 6/13/09, it will have a crew of 7. When that happens, will that be the most humans ever in space at one time? Amazing, when you th...
