Science!! Fucking magnets, how do they work?

We can always go back in time and start a terrorist organization to stop them.

I want to try some of that. I have a feeling it tastes nasty though. Could be great emergency food storage though.

The left turn will forever be the bane of our existence.

Well its about fucking time!!!

NASA's New Design for a Warp Drive Ship
http://io9.com/heres-nasas-new-desig...hip-1588948192

What's sad is the typical FB morons will read that headline and think that scientists are on the verge of FTL travel. Nevermind the fact that we haven't even figured out cold fusion much less something that requires infinite energy.

It doesn't violate relativity or require infinite energy. It works by warping spacetime around the ship. So while the net effect is the ship going faster than light, from the ship's reference it is not.

My understanding is it is currently at the "theoretically possible" stage. It's definitely worth investigating, though

Yes, it doesn't require infinite energy but it still does require "exotic" matter. Which means, whatever the power source is, it still needs to produce more than even what would be produced with fusion energy (Or, at least, that's how it was explained to me). Essentially, it needs whatever the "next step" beyond fusion might be. The whole redesign just got scientists excited because it changed the mass requirements of that magic energy from Joavian in size, into space ship size. (So, theoretically, one day, if we actually develop a kind of mythical "star trek" anti-matter reactor? FTL travel would totally be possible. Which IS exciting, but only because it means our travel is now tied to power production, and not time.)

A comment on that article said it best. Now we only need a small bucket of unicorn tears to power our FTL ship--the problem is, we still need unicorn tears, heh.

Study: Vast Underground 'Ocean' Discovered Near Earth's Core

Click to expand...

I really wish that people would stop running with that story.

Everyone who has spoken to me believes that it is a real, liquid ocean, just sloshing around in 500+ heat, with pressure greater than we can imagine. It is suspended in a mineral known as ringwoodite, which in concentrations, can have as much as something like 2-3% of it's total mass being suspended liquid.

So it's just a porous, wet, layer of rock. How can that be considered "near the core" when the radius of the earth is 4,000 miles? That's like... upper mantle.

And I assume that the claim of "3x more water than all the oceans on the surface" is assuming that the layer is contiguous, rather than being a local feature.
