The area is fairly small as I'm using this for an autonomous robot application so the accuracy I'm trying to reach is as presice as I can (a few meters). I'm giving it points that it has to go to and it has a GPS to give it longitude and Latitude. By converting longitude and latitude to meters...

Hi, I'm trying to convert latitude and longitude into meters (x,y). I was thinking of UTM however I don't understand the equations as the ones I've seen just go on forever. Could someone help me understand how to use these equations? heres the website that I've been trying to understand...

no, wormholes could possible send you to a different time (say past or the future) warp drive will keep you in the same time.

how accurate is accurate? Say if I have geocentric coordinates of the moon is 10 arc seconds a resonable accuraccy if someone wanted to send something to the moon?

isn't that a worm hole? warp drives just warp space time not punch a hole through it.

Yes it would be flat. However it is impossible to remove all influence of gravity because gravity has no bounds.

No sorry.:frown:

To me warp drive will not be possible until a few centuries if ever. The reason being is that the theory of the warp drive is that you "shrink" space time in front of you then "expand" while you sit inside a bubble that goes along for the ride. Find any way to make those two things in qoutes...

than what came out the bb? something had to come out of it in order to create the universe.

Couldn't you consider the big bang as a white hole? where mater just comes spilling out at a single moment.

thanks for the help everyone. I found my problem. It seems like I switched a number in the vis-visa equation, 1/r instead of 2/r. Stupid me :rolleyes:. That fixed it. Now my values are exactly like what http://nssdc.gsfc.nasa.gov/planetary/factsheet/moonfact.html" said. D H I'm interested...

ok, i tried all you suggested however i still have a number of .2454 km/s or 245.5 m/s. I'm not sure this is right because of these values: http://nssdc.gsfc.nasa.gov/planetary/factsheet/moonfact.html" it says that min. orbital speed is 0.964 km/s. I'm not sure what to think now.:confused:

ok, I'm having difficulties in finding the velocity of the moon from a certain distance from the earth, the equation I'm using is the vis-viva equation: v=\sqrt({}\mu*(2/r-1/a)) \mu=GM=3.98694E+14 r=radial distance from focus to orbiting object=369397 km (periapsis of moon)...

because of gravity. Andromeda is actually fairly close (and by that i mean thousands of light years) meaning gravity dominates over the rate of expansion. And just to add to the thread... Two months or so ago an article about dark energy came in Scientific America. It showed how dark...

think of it this way, I'm not 100% sure but i because sapce and time are related (space-time fabric). If you rip a hole in one place to another, you not only rip space but also time. Which, as far as my understanding is, you may not arrive in the same time.
