The closest star system to Earth, just over 4 light-years away, has three stars and at least one Earth-sized planet. Is it time to go there?
With advanced laser technology and an appropriate sail, we could accelerate objects to ~20% the speed of light. But would they survive?
Forget about the terawatt lasers we’re making on Earth. This natural one is thousands of times more powerful than the Sun.
The hunt for the elusive particles continues.
If you think you know how an astronomical nova works, buckle up. You’re in for a ride like you never expected.
Before we formed stars, atoms, elements, or even got rid of our antimatter, the Big Bang made neutrinos. And we finally found them.
Implanting machine components into human bodies, argues one scholar, could make for a better society.
If something exists, it is by definition natural.
In all mammals, there are two brain pathways for processing information from the eyes: an evolutionarily ancient one and a more modern one.
The idea that “you” persist after death does not hold up to the current understanding of memory and identity.
What would it take to create a truly intelligent microbot, one that can operate independently?
The idea of gravitational redshift crossed Einstein’s mind years before General Relativity was complete. Here’s why it had to be there.
When stars form, they emit energetic radiation that boils gas away. But it can’t stop gravitational collapse from making even newer stars.
Pluto failed to meet the definition of a planet, but some astronomers think there might be a legitimate Planet 9 out there.
If life is common in the Universe, then where is everybody? Known as the Fermi Paradox, a new project may help solve the riddle.
The most celebrated genius in human history didn’t just revolutionize physics, but taught many valuable lessons about living a better life.
First derived by Emmy Noether, for every symmetry a theory possesses, there’s an associated conserved quantity. Here’s the profound link.
Laser-guided lightning systems could someday offer much greater protection than lightning rods.
Flies are in no way smart, but they experience time in an almost Matrix-like fashion.
We know the Universe is expanding, but scientists don’t agree on the rate. This is a legitimate problem.
The discovery calls into question the few things scientists know about these powerful astronomical phenomena.
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?
As technology advances, the use of laser weapons in space becomes more likely.
Are quantum fields real, or are they simply calculational tools? These 3 experiments show that if energy is real, so are quantum fields.
The first recorded brain activity of a person during their death suggests a biological trigger for near-death experiences.
It didn’t look like anything I’d seen before, but I’d be a great fool to consider “aliens” as a reasonable possibility.
Yes, the Universe is expanding, but you might wonder, “How fast is it expanding?”
The light from Earendel took 12.9 billion years to reach Hubble. The star is millions of times brighter than our Sun and 50 times as massive.
When Einstein gave General Relativity to the world, he included an extraneous cosmological constant. How did his ‘biggest blunder’ occur?
