Scientists gear up to take a picture of a black hole

On Wednesday, Jan. 18, astronomers, physicists and scientists from related fields will convene in Tucson, Ariz. from across the world to discuss an endeavor that only a few years ago would have been regarded as nothing less ...

Travel through wormholes is possible, but slow

A Harvard physicist has shown that wormholes can exist: tunnels in curved space-time, connecting two distant places, through which travel is possible.

NASA thinks there's a way to get to Mars in three days

We've achieved amazing things by using chemical rockets to place satellites in orbit, land people on the moon, and place rovers on the surface of Mars. We've even used ion drives to reach destinations further afield in our ...

Beyond the black hole singularity

Our first glimpses into the physics that exist near the center of a black hole are being made possible using "loop quantum gravity"—a theory that uses quantum mechanics to extend gravitational physics beyond Einstein's ...

Time reversal findings may open doors to the future

(Phys.org)—Imagine a cell phone charger that recharges your phone remotely without even knowing where it is; a device that targets and destroys tumors, wherever they are in the body; or a security field that can disable ...
