Is it better to be rational or optimistic? Steven Pinker explains.
Ernst Haeckel
He was also a eugenicist — but at least he could draw pretty pictures.
dark energy accelerated expansion
Yes, dark energy is real. Yes, distant galaxies recede faster and faster as time goes on. But the expansion rate isn't accelerating at all.
galaxies
We only need two numbers to understand why.
Concluding that Damar Hamlin's cardiac arrest was caused by the COVID vaccine requires accepting highly improbable leaps of logic.

The quantum world — and its inherent uncertainty — defies our ability to describe it in words.
In 1920, astronomers debated the nature of the Universe. The results were meaningless until years later, when the key evidence arrived.
mixed reality
2023 will see an "arms race" in mixed reality hardware and software. This truly will revolutionize our society.
negative energy
Quantum mechanics has taught us that even empty space contains energy. "Negative energy" is the state of having less energy than empty space.
As time goes on, dark energy makes distant galaxies recede from us ever faster in our expanding Universe. But nothing truly disappears.
Passing chunks of ice can fertilize ocean waters and play a role in the planet’s carbon cycle.
2023 space missions
2023 will see the launch of new rockets, the return of OSIRIS-REx, and a mission to Jupiter that could help us find extraterrestrial life.

In the grand scheme of the cosmic story, a single year isn't all that significant. But over time, the annual changes really add up!
It was originally recorded in the 1970s by cognitive psychologists Harry McGurk and John MacDonald.
Only recently have scientists directly witnessed this most pivotal of events in biology.

Sharing food and kissing are among the signals babies use to interpret their social world, according to a new study.
Evolution repeatedly hit upon this solution simply because it works.
Since dark matter eludes detection, the mission will target sources of light that are sensitive to it.
