Not everything needs a medium to travel through. If we can overcome that assumption, we don’t need the aether at all. All throughout the Universe, different types of signals propagate. Some […]
The Oedipal complex, repressed memories, penis envy? Sigmund Freud’s ideas are far-reaching, but few have withstood the onslaught of empirical evidence.
Is it “perverseness,” the “death drive,” or something else?
Scientists have replicated Albert Einstein’s spooky action at a distance on a massive scale—well, for the quantum world, anyway.
A massive black hole at the center of the Milky Way and a single star did it.
While shuffling off their mortal coils, these giants of thought had some parting words.
Both schizophrenics and people with a common personality type share similar brain patterns.
Physicists prove a core part of the theory of general relativity by using the whole Earth and the most precise clocks ever.
We often like to consider the ideas of great thinkers when looking at an issue. To that end, Albert Einstein once wrote an essay explaining why he was a socialist. We break it down here.
Scientific surprises are often how science advances. But more often than not, they’re just bad science. When you’re a scientist, getting an unexpected result can be a double-edged sword. The best […]
Renowned scientists and technologists who’ve passed away in 2018.
It’s not simply Hubble’s Law anymore, but the real history is far more complex than the stories you’ve heard. One of the most mind-blowing facts in our existence is that space […]
As individuals, we scientists are all flawed. But the enterprise of science rises above our individual shortcomings. The enterprise of science is perhaps the greatest achievement in all of human […]
Einstein didn’t like the schools he went to, how would he improve them?
In 2017, we saw gravitational waves a neutron star merger for the first and only time. And it keeps getting more interesting. On August 17, 2017, a cosmic signal arrived […]
A single thought experiment reveals a paradox. Could quantum gravity be the solution? Sometimes, if you want to understand how nature truly works, you need to break things down to […]
On September 27, 1972, scientists performed the first test of Bell’s inequality. God does play dice with the Universe, after all. One of the most puzzling and counterintuitive aspects of quantum […]
Faraday’s law of induction was set forth in 1834, and was the experiment that led Einstein to discover relativity. When we think about Einstein and the theory of relativity, all […]
History will remember Stephen Hawking for his many contributions to cosmology and astrophysics, but his beliefs about the future could soon prove just as important.
Rates of centenarians are going to increase eightfold in the next three decades.
Nothing can go faster than the speed of light in a vacuum. But particles in our Universe can’t even go that fast. When it comes to speed limits, the ultimate one […]
In 1922, Albert Einstein explained how to live a happy life to a bellboy in Tokyo.
What can cause a ripple in both space and time? Neutron stars colliding. And what can observe that phenomenon? A two-mile-long laser.

The result validate Einstein on a whole new scale, and pose serious problems for alternative, modified theories of gravity. In 1915, Albert Einstein put forth a new theory of gravity: General […]
New research on the hypothalamus shows that body heat matters.
Stephen Hawking had pinned his hopes on ‘M-theory’ to fully explain the universe – here’s what it is
During the second string revolution, in 1995, physicists proposed that the five consistent string theories are actually only different faces of a unique theory.
Albert Einstein’s famous thought experiments led to groundbreaking ideas.
