Fuel Free Spacecrafts Using Graphene

Posted by samzenpus on from the to-the-stars-and-beyond dept.

William Robinson writes: While using a laser to cut a sponge made of crumpled sheets of Graphene oxide, researchers accidentally discovered that it can turn light into motion. As the laser cut into the material, it mysteriously propelled forward. Baffled, researchers investigated further. The Graphene material was put in a vacuum and again shot with a laser. Incredibly, the laser still pushed the sponge forward, and by as much as 40 centimeters. Researchers even got the Graphene to move by focusing ordinary sunlight on it with a lens. Though scientists are not sure why this happens, they are excited with new possibilities such as light propelled spacecraft that does not need fuel.

    All great discoveries can be summed up with three simple letters... WTF

    Lets test your hypothesis by creating a slashdot poll.

    If only there was a giant source of light in the galaxy constantly releasing more energy then we ever could hope to use that we could harness...

    Look, if I can't be pedantic on /., where am I supposed to go?

    Do you ever get the paranoid feeling that someone is occasionally modifying the laws of physics in order to advance the plot?

    "Oh look, they're going to be stuck on Earth for an excruciatingly long time due to the exponential-propellent-scaling problem. Let's add a new capability to graphene that will give them a work-around for that."

    I claim that two years ago the exact same graphene experiment would have shown no unexpected results; but now in 2015 we see this suspiciously useful behavior appear. I'm not sure how to test my hypothesis though :)

    I don't care if it's 90,000 hectares. That lake was not my doing.

      You're not supposed to talk about the expansions like that. This is a RP server.

    I'm no physicist, but I'm pretty darn sure a spaceship's gotta move a whole lot further tan 40 cm to get anywhere.
