This may require room for a new highway

Huh? I only read the Slashdot article, not the paper, but my understanding is that motion in the FTL realm is understood other than for the pesky i term in the equations. The problem is the discontinuity at c that keeps you from getting there.

So once you get over the 'infinite mass' hump at light speed, you can start saving fuel the faster you go

Sounds like the crap I filled a ream of scrap paper with while in grad school. They really thought it was worth publishing?

Oh, they ran mathematica and made colorful 3-D graphs. Carry on.

Relativity prohibits acceleration beyond the speed of light. Travel beyond the speed of light involves interesting maths, but isn't explicitly forbidden.

I can't help but wonder if particles that already exist beyond the barrier presented by c are what contribute to this whole "dark energy" thing.

Not sure how they get around the whole SQRT(negative number) once you get past c. And the guy compares going faster than light as comparable to going faster than sound in 1947. Scientists never said faster than sound wasn't possible, the V2 already went faster than sound in WWII.

Could it work the other way around too? Like, I decrease my speed (or energy) to infinitely close to zero and it makes my mass to grow to infinitely big and I pop into a different universe with different rules for physics? It is theoretically possible, isn't it.

"Infinite" is just another word for "couldn't be bothered to do all the math".

/I recall reading before about Tachyons that don't go slower than light,
/and how science was theorizing the universe could be broken into two sets of speed rules.
/then we've got that missing mass and dark energy problem.
/One might wonder if its not all related somehow.
/Might make for good sci-fi plot material.

Isn't warp drive just that? Bend space to bring points A and B closer, then travel at near light speeds to get from A to B? Basically, with the Enterprise you could actually make the Kessel Run in under 12 parsecs if your warp drive was powerful enough.

This doesn't seem to take into account anything at all for length contraction. As an object approaches c, it's physical dimension in the direction of travel contracts so it ends up looking like a 2 dimensional pancake. Conversely, to the object in motion, the entire universe would appear to be contracting the same, so that once it reaches c the entire universe would appear to be something like a 2 dimensional plane. What happens after c? Does everything just turn inside out?

Makes sense. Human's scientific history has always been a cycle of "It's impossible to do A. Now we can do A."

Hawnkee: Makes sense. Human's scientific history has always been a cycle of "It's impossible to do A. Now we can do A."


They didn't say it was possible. They described mathematically what would happen if it was possible.

That whole "infinite energy required to accelerate an infinitely-increasing mass to c" hump still appears to be quite valid.

"In effect, the singularity at the speed of light divides the universe into two"

So basically their argument is "you can't get there from here, you have to go somewhere else first".

No, it's more like "if you were already there, this is what it would look like."

Hawnkee: Makes sense. Human's scientific history has always been a cycle of "It's impossible to do A. Now we can do A."


If you were paying attention, the whole point is that we understand travel at faster-than-light and slower-than-light speeds, it is just the pesky at-light speed that is the problem. If you are STL, you can't go FTL. If you are FTL, you can't go STL. We have no way of jumping between those states and no evidence that it is possible. Humanity has been more "I think it is impossible to do A though there is reason to believe it may be possible. Now we can do A."

And bullets prior to WWII. And IIRC cosmic rays were understood to include massive particles traveling at near light speed in the 20's or 30's
