Reaching Mars in a Few Days Possible? Yes! says NASA | VIDEO


     Ever since NASA announced plans to send a manned mission to Mars in the 2030s and Hollywood got in on the action with "The Martian," the Red Planet has loomed large in our collective imagination. Now, thanks to a video released by NASA, we can add a new bit of heat to Mars fever -- the idea that we could get to the planet in just a few days.

"There are recent advances that take this from science fiction to science reality," scientist Philip Lubin says in the video, titled "Going Interstellar." "There is no known reason why we can not do this."

Light Stopped For Minute In Record-Breaking Study

Light Stopped For Minute In Record-Breaking Study

    Albert Einstein postulated that nothing is faster than the speed of light. But what if light was stopped dead in its tracks for, say, a minute? Impossible, right? Think again.

Researchers at the University of Darmstadt in Germany achieved an incredible feat when they stopped light for an entire minute inside a crystal.

In a paper about their research, published this month in the journal Physical Review Letters, the scientists explain how they stopped the light using a technique called electromagnetically induced transparency.

The researchers beamed a laser at an opaque crystal, triggering a quantum reaction that turned the crystal transparent. Then they directed a secondary light source at the crystal before cutting power to the laser to render the crystal opaque again.

What happened? The light from the secondary source remained trapped inside the crystal. Through multiple trials, the team was then able to extend the period of time in which the light remained halted within the crystal for up to a minute. . . .

Warp Drive Feasible? Relativity Loophole Means 'Star Trek' Device Might Actually Work, Physicists Say | VIDEO

Warp Drive Spacecraft

      In the "Star Trek" TV shows and films, the U.S.S. Enterprise's warp engine allows the ship to move faster than light, an ability that is, as Spock would say, "highly illogical."

However, there's a loophole in Einstein's general theory of relativity that could allow a ship to traverse vast distances in less time than it would take light. The trick? It's not the starship that's moving — it's the space around it.

In fact, scientists at NASA are right now working on the first practical field test toward proving the possibility of warp drives and faster-than-light travel. Maybe the warp drive on "Star Trek" is possible after all. . . .
