People may have once called what scientists were doing with electrical charges impractical and not useful but look what happened. Understanding is part one and hte second part is making something from that understanding. Earth will run out of resources and/or be unfit for human habitation at some point so there needs to be a plan B if worst comes to worst for humanity.

Oh, absolutely. We're running out of metals, natural fuels, land, drinkable water...everything, basically. But I think that if we took all of these people who have an amazing understanding of physics and put them all into fields like conservation of materials, it would have a much better effect than trying to come up with a wacky way to throw us all into a black hole to zap us to another world.

As for electricity, again, its effect is something that can be seen, felt, and manipulated (i.e. a lightning strike, electrons passing through you, and a battery). When you show me how to easily travel back in time and bend space to a useful endeavour, I'll say I'm wrong.

NASCAR and F1 racing are the biggest slaps in the faces to humans. The fans are just too stupid to realize it.

Vrroom broom, yay, waste of natural gas to go round and round. VROOM!!!!!

Well we already know we can go forward in time. And there are plenty of scientists working on climate change solutions. The biggest idea put forth to stop it is cutting carbon emissions but humans are too dumb to realize we're destroying the planet. It may be too late when they realize they need to stop. That's business and politics for ya.

I just think it's amazing all that's happened in 6000 years

yeah, I don't get it either. I'd rather watch monster trucks, if I had to watch any "automotive sport".

Yeah, we've done a pretty good job of destroying our planet and using all of its resources in the past 200 years or so. Also, of course we can go forward in time; I've done it in the time taken to type this.

Then again, I can't PROVE that I've gone forward in time, as I cannot prove that everything except for the present moment is not a dream world I created in my head...but that's a different discussion altogether.

I mean, I understand that all forms of entertainment use resources (hockey uses refrigerators for artificial ice, has heating, electronic equipment, the actual construction materials, etc.) But automotive racing uses up one resource that is, so far, impossible to synthetically produce without a net loss of energy. It's really a colossal waste just to watch dudes drive around for a few hours.

No, no I mean we can move faster than time. Massive objects warp spacetime. The closer you are to Earth, the slower you are moving in time. Our heads are younger than our feet but not noticeably, obviously. If we orbited a black hole for an hour or so and returned to Earth, the world would be 100 years older and we'd only be an hour older.

Can you prove that I can't prove that you can prove that I can prove it?

I think you'd need a lawyer to accomplish that

and how do we prove this? cut off our heads and feet and count the rings?

That's using gravity's effects to change time at a different relative rates. That's not really controlling time, it's using gravity (LARGE differences in it) to scale time.

so cutting through all this time/space bullpoop, did Carter's shot get deflected or not?

I'm not sure. They could end up in the lottery.

For 3 dimensional beings, this is time travel as we currently know it. Travel near light speed and relativism will play it's role too. There are or will be practical applications for this too, I'm sure.

I don't really call it "time travel." More of a gravity-induced rate of change in time realtive to another rate of change in time. True time travel, to me, would be to go to another specified place in time (forward or reverse) at will.

As I understand it, the closer we come to light speed travel, the lower our mass becomes (E=mc^2 where E=constant). As speed approaches infinity, do we become creatures of pure energy (like the transporter on Star Trek)?

The theory is that mass would need to be infinite to travel at light speed which is why traveling at that rate or faster doesn't seem like our best bet for interstellar or even interplanetary travel. Wormholes, moving spacetime, warping space time, anti-matter engines, suspended animation, etc. are all more plausible ways to travel lightyears.

As for time travel as you define it, that may need us to be able to transcendent the 3 dimensions. There are also paradoxes involved with backwards time travel which complicate things.

As I sit here preparing the syllabus for the Evolutionary Biology class I am teaching this semester...please allow me to thank you for the laugh!

You bring up anti-matter. I know we have created anti protons, but I don't understand it. Two things:

1. When matter and anti-matter collide, they basically cause a high-energy explosion.
2. We live in a world filled with matter.

So, if we live in a world of matter, and anti matter and matter explode when they come into contact, how have we constructed anti-matter and had it exist for up to 17 minutes?

Containing it would be key and at the moment we don't know how to do that. That's something that needs figuring out. I'm sure we will at some point barring our extinction in the next few centuries or at least a setback.

I think anti-matter has to come in contact with matter of corresponding atomic whateverness (i.e. anti-oxygen would only annihilate when in contact with normal-oxygen)
