Scientists are solving the problem of costly energy storage.
It has no moving parts and could allow us to tap into renewable energy year round.
A community in Austin, Texas is using geothermal energy to keep homes warm in the winter and cool in the summer.
By digging deep, we could harness enough energy to power generations to come. But it involves fracking.
The Kardashev scale ranks civilizations from Type 1 to Type 3 based on energy harvesting.
Over time, the Universe becomes less dominated by dark matter and more dominated by dark energy. Is one transforming into the other?
More than any other of Einstein's equations, E = mc² is the most recognizable to people. But what does it all mean?
A "bio-battery" made from genetically engineered bacteria could store excess renewable energy and release it as needed.
Wind energy is one of the cleanest, greenest sources of power. But could it have the sneaky side-effect of changing the weather?
Smashing things together at unprecedented energies sounds dangerous. But it's nothing the Universe hasn't already seen, and survived.
The idea of gravitational redshift crossed Einstein's mind years before General Relativity was complete. Here's why it had to be there.
Even though the brain is only 2% of our total body mass, it consumes up to 25% of our energy.
13.8 billion years ago, the hot Big Bang gave rise to the Universe we know. Here's why the reverse, a Big Crunch, isn't how it will end.
The Big Bang was hot, dense, uniform, and filled with matter and energy. Before that? There was nothing. Here's how that's possible.
Should you blast the A/C even when you're not at home?
A new paper combines two concepts from the edges of astrophysics: Dyson Spheres and black holes. A Type III civilization could combine them.
From black holes to dark energy to chances for life in the Universe, our cosmic journey to understand it all is just getting started.
“I thought, why not direct these high-power beams, instead of into fusion plasma, down into rock and vaporize the hole?”
There are two fundamentally different ways of measuring the Universe's expansion. They disagree. "Early dark energy" might save us.
NASA will use energy from Earth's gravity to launch the Lucy spacecraft in October of this year.
“Should they strike, each of them has an energy at impact equal to all of the nuclear weapons on Earth combined."
We frequently say it's 2.725 K: from the light left over all the way from the Big Bang. But that's not all that's in the Universe.
Creating an afterlife—or a simulation of one—would take vast amounts of energy. Some scientists think the best way to capture that energy is by building megastructures around stars.
