There are also many uses for magnets that were not mentioned, like the MRI. It uses magnetic fields to "see" into you like a colorful X-ray. Also they are used to hold things on the fridge. As for propelling a ship through space....when they conquor earth may be the aliens will tell us

Ever look at the table of ellements? Wouldn't you think that on the other side of the universe there might be materials there that would make the energy we get from an atomic bomb look like a sparkler?

Ion power... is teh shit... Unlimited top speed it just keeps propelling because the energy level just keeps expanding. Thats what they use for deep space probes now.

and are you aware how long it takes for this system to get up to any useful speed?
while you're (very) slowly accelerating, you still need fuel/food to keep passengers alive, all of which means more mass, which means even slower acceration.
there's a reason why they (can) use it for probes and that's because they have an operation time frame of years and sometimes, tens of years and do not require life support.

Yes...

But this s all in good fun... relax man...

i am relaxed.
just pointing out a little extra fact in case someone else reads what you typed and takes it as absolute truth and begins to cite your post as "something they read" in another thread somewhere regarding propulsion systems.

there was an article in discover magazine about future propulsion systems. one that stood out to me was thes fusion ramjet. it has a big cone aty the front to collect matter floating in space adn uses it in a fusion reaction to propel it. another was using a giant sail powered by solar winds and a laser guided from earth. the downside was to power the laser you would need 6 times the amount of power used in the world in 1 second. youd have to build a big ass solar several miles wide to produce enough. but it was a fast method of traveling. then theres the good old star trek matter/antimatter reaction, still plausible.

except that in order for the star trek science to work, they had to invent a material (read: a form of matter) that was porous to anti-matter. simple common sense tells you that this is impossible.

there are ways (not sure if they've actually managed to do it yet) to not quite contain anti-matter in a semi safe environment but the practicalities of doing such, is more or less pointless.

and your post reminds me of something else.
in space, you do still have friction as the vacuum of space isn't actually 100% nothing.
the best vacuums are man made.

Supposing the gas tank lasts long enough to go there and back I doub't you be able to get to any nearby solar systems since the tank would be so huge its mass would limit its acceleration. Not to mention a trip at even light speed to the second nearest star (our sun being the closest) would take hundreds of years.

Actually the nearest star is Alpha Centauri at a little over 4 years, if we could travel at light-speed. But I'm not sure why anyone would want to go there, as it has no planets.

Yeah, im pretty sure they have contained it, but i don't see a point at this stage other than its interesting. Hopefully as science develops they can make use of it.

actually proxima centauri is closer than alpha but its only a red dwarf.

GForce957 · #56 10-20-2005, 11:34 PM

oh woops, well at least i got the system and the distance...

blakscorpion21 · #57 10-21-2005, 01:22 PM

haha actually i hear alot of sources say the closest is alpha and alot say proxima. but im pretty sure proxima is closer. its weird how even at the speed of light which is hundreds of times faster than anything we have today it would still take 4 years. our best efforts for long travel havent even reached past our solar system. ie voyager.

GForce957 · #58 10-21-2005, 02:51 PM

Where is voyager now? past neptune?

blakscorpion21 · #59 10-21-2005, 03:59 PM

i think so. well prob. make a ship in the near future that will pass it up on a journey into deep space and laugh at how slow it is. lol
