Apart from the energy needed to flip the switch, no other energy is needed to transmit the information.
Ironically, the company did so using technology perfected by the oil industry.
Quantum mechanics has taught us that even empty space contains energy. "Negative energy" is the state of having less energy than empty space.
Einstein's most famous equation is E = mc², which describes the rest mass energy inherent to particles. But motion matters for energy, too.
All forms of energy affect the expanding Universe. But if matter and radiation slow the expansion down, how does dark energy speed it up?
Capacitors, acid batteries, and other methods of storing electric charges all lose energy over time. These gravity-fed batteries won't.
Decades ago, a disaster left three million acres of land uninhabitable and killed between 85,600 and 240,000 people. Chernobyl? No. Banqiao dam in China.
Experiments on suborbital rockets are revealing how to make a better iron furnace.
You are an energy field — but not the “chakras” or “auras” kind.
The material is both stronger and lighter than those used to make conventional power plant turbines.
Nuclear fusion has long been seen as the future of energy. As the NIF now passes the breakeven point, how close are we to our ultimate goal?
There may be more energy in methane hydrates than in all the world’s oil, coal, and gas combined. It could be the perfect "bridge fuel" to a clean energy future.
The robot can drive heavy steal beams into the ground at a rate of 1 per 73 seconds, which will help expedite solar farm construction.
Amplifying the energy within a laser, over and over, won't get you an infinite amount of energy. There's a fundamental limit due to physics.
As time goes on, dark energy makes distant galaxies recede from us ever faster in our expanding Universe. But nothing truly disappears.
Across all wavelengths of light, the Sun is brighter than the Moon. Until we went to the highest energies and saw a gamma-ray surprise.
What if we could harvest energy from human heat, sweat, or vibrations?
McDermitt Caldera, the site of an ancient volcanic eruption, straddles the border of Oregon and Nevada.
The highest-energy particles could be a sign of new, unexpected physics. But the simplest, most mundane explanation is particularly iron-ic.
Don't put all your eggs in one basket.
If you gave me $400 and I gave you $3.15, would you consider yourself wealthier? That's a financial analogy for the supposed fusion power "breakthrough."
An enormous amount of antimatter is coming from our galactic center. But the culprit probably isn't dark matter, but merely neutron stars.
