See what you all think of this scientific movement ?? http://www.keshefoundation.org/

I'm most definitely interested. I can at least be a coffee-getter for the brains doing the math. Lol
I'll even find us a chimp named Buck Rogers to test drive the prototype.

Let's put some research together on warp drive. I'll get a scientist friend involved who claims to have created warp drive. Who's in?

not to get all mathie on you, but you can't fifth power a rate of speed, you can only meaningfully fifth power a pure number (and what units of measure would you choose?).

So, what is the fifth power of the speed of light (as number only): 1 (light years / year).

Even Warp 2 is preposterous: 90,000,000,000 sq km / second squared, not very meaningful.

I'm not saying it is YOUR mistake...

Not to sound like a fan boy, But Warp spead is not time the speed of light, such as 5 times c but  c to the fifth power.

Well, I am pretty sure that I didn't suggest that it could be done, rather I suggested the futility of it all.  At c, time stops for the traveler even if it takes 8 years to make a round-trip to Proxima Proxima, not to mention how long a trip to Sirius would take, rendering his/her trip a bit meaningless on return some 17+ years later.  Not to mention that memory is a function of perceived time, so he/she will have no memory of the trip itself.

Which does NOT in any way keep me from loving sci fi with interstellar travel, even tho Star Trek assumes Warp speeds which are STILL not fast enough to go anywhere, no matter how you define warp (I mean at Warp 100, it still takes 4.5 months to get to Prox Prox, as measured on Earth (neglecting the reverse time travel on board, which assumes that Albert was wrong, but who cares!)).

We need to get it right here.  Any discussion of interstellar flight HAS to be fanciful.

Well, the thing is, if you really can develop a ship that travels faster than the speed of light relative to the Earth from which it left, then quite frankly I'll bow down to you as the one who is awarded the Nobel Prize for being the first one to determinately prove that Einstein's Special Theory of Relativity, and by extension his General Theory, are both wrong.  The point is when I say it left from Earth it left from what we consider 0 relative velocity to a speed greater than the speed of light; but a particle *is* allowed to travel faster than light if it *never*, in its entire history, travels slower than the speed of light.

That said, you could travel the universe in a lifetime onboard a near-light-speed space ship.  Because Time Dilates with speed, the closer you go to the speed of light, the more time on board the space ship seems to have slowed down relative to Earth.  Go fast enough and time will slow down so substantially that it will feel like you're traveling faster than light, but while you travel, everything is also sped up so you may cross the Universe but it might take your ship tens of billions of years to get there relative to Earth and add to that the space dilation which compresses your entire 360° view into a point right in front of you.  What's more, it'll be so blue-shifted that you'll receive all light as high-energy gamma radiation and this will pretty much fry your ship back to atoms, never mind looking at it.

Jeffrey.

It seems that astronauts would get younger going faster than light, but they'd return from a 8 year round trip not much less than 8 years LATER, with the crew being younger than they were at the beginning.  This method seems not to gain WARP speed of multiples of times c, just fractionally more than c.

No, it's not the scenic overlook in the Italian Alps where we used to go to make out.

Several of us from the first meeting are interested in learning about this.  Some of them may actually be able to.  As far as we can tell, this is the only credible thing raised in public that might lead to interstellar travel down the road.  Given that, seems like a good starting point.  Anyone interested in pursuing this further, speak up.  If there are enough of us, and if we feel like we have a prayer, we might form a sub-geek to attempt to comprehend it as a collective.  The involvement of mind-expanding drugs in said undertaking has not been ruled out.
