In all of science, no figures have changed the world more than Einstein and Newton. Will anyone ever be as revolutionary again?

We cannot afford to dream about living on other worlds while we continue to destroy ours.
“It is more human to laugh at life than to lament it.”
Light can be turned into heat, which can then be turned into motion, and the effect of that motion can be turned into a big squeeze.
No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?
A new measurement offers insights on the density of the mysterious force driving the Universe’s expansion.
Even the dictionary doesn’t get the definition right.
We knew we’d find galaxies unlike any seen before in its first deep-field image. But the other images hold secrets even more profound.
The strongest tests of curved space are only possible around the lowest-mass black holes of all. Their small event horizons are the key.
All forms of energy affect the expanding Universe. But if matter and radiation slow the expansion down, how does dark energy speed it up?
Astronomers in 2017 caught an image of a supermassive black hole in a galaxy far, far away. Doing it in our own galaxy is a huge milestone.
No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?
Chemists could replace bubbling flasks with tumbling ball mills.
In logic, ‘reductio ad absurdum’ shows how flawed arguments fall apart. Our absurd Universe, however, often defies our intuitive reasoning.
At 1,600 light years away, the black hole is practically in our cosmic backyard.
When stars form, they emit energetic radiation that boils gas away. But it can’t stop gravitational collapse from making even newer stars.
“Imagination is more important than knowledge” is often taken to mean that your conceptions outweigh what’s real. That’s not what he said.
Dr. Tyson explains where we might find aliens, why “dark matter” is a misleading term, and why you can blame physics for your favorite team’s loss.
For many years, cosmologists have claimed the Universe is 13.8 billion years old. A new paper says no, it’s 26.7 billion. How do we decide?
There are a few clues that the Universe isn’t completely adding up. Even so, the standard model of cosmology holds up stronger than ever.
Pessimism reigned supreme.
Please stop calling our Sun an “average star.” It is philosophically dubious and astronomically incorrect.
A recent experiment challenges the leading dark matter theory and hints at new directions for uncovering one of the Universe’s biggest mysteries.
In our Universe, matter is made of particles, while antimatter is made of antiparticles. But sometimes, the physical lines get real blurry.
The carnival spirit was in full swing when the priests got wasted and made indecent gestures while dressed like pimps.
To Einstein, nature had to be rational. But quantum physics showed us that there was not always a way to make it so.
Einstein hated “spooky action at a distance,” but much to his chagrin, quantum mechanics remains as spooky as ever.
NASA’s minivan-sized drone is scheduled to search for signs of life on Titan in 2034.
Ultracold gases in the lab could help scientists better understand the universe.
