Is time travel possible?

This week's question concerns the concept of time travel. Usually the topic of science fiction books and movies, two of the world's most respected physicists, Stephen Hawking and Michio Kaku, assert that time travel could become a scientific reality. In a recent AOL Science article, both scientists cited Einstein's belief of a fourth dimension -- known as time -- as grounds for the possibility of time travel. They also suggest wormholes and black holes could be useful in achieving time travel.

What do you think? Is time travel possible?

Hermetic Feedthroughs: A Critical Component in New Flywheel Energy Storage Solutions

The phrase “everything old is new again” certainly applies to today’s flywheel technology. Forget the mechanical bearing, standard atmosphere 5,000 RPM steel behemoths of the past, many of today’s flywheel designs feature compact carbon fiber composite rotors on magnetic bearings, turning in a vacuum at up to 60,000 RPM.

Purple Bacteria and Photovoltaics

Purple bacteria are single celled microscopic organisms that were among the first life forms on Earth. The tiny organisms live in aquatic environments and use sunlight as their source of energy. Neil Johnson, a physicist at the University of Miami, thinks its cellular arrangement could be adapted for use in solar panels.

Should the oil spill in the Gulf of Mexico affect the President’s energy plan?

This week’s question concerns the recent oil spill in the Gulf of Mexico. After a rig leased by BP Plc exploded and sank last week in the Gulf, many have indicated that the President may experience a setback in his plan to expand offshore drilling. The plan is supposed to be part of a transition to a new energy economy that relies less on imported fossil fuel and more on domestic power from the sun and wind.

What do you think? Should the oil spill in the Gulf of Mexico affect the President’s energy plan?

Bionic Coating for Fuel-Efficient Ships

The water fern salvinia molesta is extremely hydrophobic, surrounding itself by a flimsy skirt of air that prevents the plant from coming into contact with liquid. This inconspicuous plant could allow ships to have a 10 percent decrease in fuel consumption.

Will digital actors ever replace humans in Hollywood?

This week's question concerns the concept of "digital actors." They've appeared in "Avatar," "The Matrix," and "The Lord of the Rings," to name a few. And with the recent surge of 3D technology in filmmaking, it appears that digital actors will be working a lot more in Hollywood.

What do you think? Will digital actors ever replace humans in Hollywood?
