For 100 years, Albert Einstein’s general theory of relativity has survived just about every test that physicists have thrown at it. Announced in November 1915, the famous scientist’s field equations expanded on Isaac Newton’s long-standing laws by re-imagining gravity as a warping in the fabric of space and time, rather than a simple force between objects.
The results of using general relativity equations actually look similar to what you get using Newton’s math, as long as the masses involved aren’t too large and the velocities are relatively small compared to the speed of light. But the concept was a revolution for physics.
Warped space-time means that light itself is affected by gravity much more strongly than Newton predicted. It also means that planets move around their orbits in a slightly altered but very significant way, and it predicts the existence of exotic objects such as monster black holes and wormholes.

Happy birthday, Stephen Hawking. The renowned physicist turns 73 today.
While Hawking has been known to weigh in on all sorts of serious topics, including alien life and religion as well as relativity, his whimsical way with words has also made us smile.

Our planet is warm. Outer space is cold. Can we take that heat difference and turn it into electricity?
Physicists at Harvard University may have found a way to do just that. They’ve proposed in a new study how to harvest the Earth’s thermal infrared radiation, and convert it into direct-current (DC) power.
“It’s not at all obvious, at first, how you would generate DC power by emitting infrared light in free space toward the cold,” study co-author Dr. Federico Capasso, a professor of applied physics and senior research fellow in electrical engineering at the university, said in a written statement. “To generate power by emitting, not by absorbing light, that’s weird. It makes sense physically once you think about it, but it’s highly counterintuitive. We’re talking about the use of physics at the nanoscale for a completely new application.”

Researchers have reportedly taken one small yet giant step towards “perfect power” — fusion, the process that powers the sun and may ultimately solve the world’s energy problems.
Fusion is similar to fission, where atoms are split releasing massive amounts of energy. But instead of being torn apart, fusion welds atoms together. It’s a perfect power because more energy is released than used, and a sort of holy grail for physicists.
To attempt it, scientists at the National Ignition Facility at Lawrence Livermore Labs in California use an ultrapowerful laser system, which melds 192 laser beams into a single incredible burst of energy that heats and compress a capsule of hydrogen fuel to the point at which fusion take place.
The result of a late September test: the amount of energy released through the fusion reaction was greater than the amount of energy used, the BBC reported.

The final nail in the coffin may have been dealt to the idea that neutrino particles can travel faster than light.
The same lab that first reported the shocking results last September, which could have upended much of modern physics, has now reported that the subatomic particles called neutrinos “respect the cosmic speed limit.”
