[pichlo] "Right, and we we're supposed to have flying cars in the year 2000. Where are those Kangal??" (or something like that)

My response:

To be honest, we do have flying cars. We have everything for it, recipe wise. Except the one key ingredient; we don't have the anti-gravity pads.... yet. And we probably will never have them.

Well, it all comes down to if we can convert (from theory into reality), antimatter. And form substances of them into " lifters ".

By which time, we would've already colonized the Moon or Mars.
And if we do, we would've transcended species and become God.
It sounds funny, but its true.

I mean how can Entropy work (every matter and the universe likes to stay away from each other) with the existence of Gravity (every matter likes to stick to each other). We haven't even solved an easy question like that.
