Measurements of the acceleration of the universe don’t agree, stumping physicists working to understand the cosmic past and future. A new proposal seeks to better align these estimates — and is likely testable.
There are a few possible solutions to the problem of interstellar travel, but they largely remain within the realm of science fiction.
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.
Which philosopher had the strongest arguments? David Hume, who raised some of the best challenges for science, ethics, and religion.
I also can’t conjure sounds, smells, or any other kind of sensory stimulation inside my head. This is called “aphantasia.”
The first supernova ever discovered through its X-rays has an enormously powerful engine at its core. It’s unlike anything ever seen.
Is science absolute? Its truths and discoveries guide us toward the nature of reality, but we must always remain open-minded to revisions.
This representation of the Bamum kingdom is a rare example of early 20th-century indigenous African cartography.
Compared to Earth, Mars is small, cold, dry, and lifeless. But 3.4 billion years ago, a killer asteroid caused a Martian megatsunami.
A new model of the Antikythera mechanism reveals a “creation of genius.”
The human brain is only the latest chapter in the ancient story of thinking on Earth.
While Mars is known as a frozen, red planet today, it has all the evidence we could ask for of a watery past, lasting for approximately the first 1.5 billion […]
“Hubble’s Law” is only an approximation, and breaks down when we need it most. From anywhere in the Universe, you can choose to look out at any other galaxy that’s present. […]
From before the Big Bang to the present day, the Universe goes through many eras. Dark energy heralds the final one.
Japan just opened to tourists for the first time since the coronavirus pandemic began, echoing the island country’s isolationist policies during the feudal era.
If we’re migrating slowly away, is our speed changing, too? Every year, planet Earth completes one revolution around the Sun while spinning on its axis. On a year-to-year basis, our […]
The highest-energy particles of all come from space, not human-made colliders. When it comes to the most energetic particle collisions of all, you might think that the Large Hadron Collider […]
From exoplanets to supermassive black holes to the first stars and galaxies, Webb will show us the Universe as we’ve never seen it before.
An artist’s impression of what the fully-deployed James Webb Space telescope will look like from the perspective of an observer on the ‘dark’ (non-Sun-facing) side of the observatory. (NORTHRUP GRUMMAN) […]
The image you’re seeing isn’t a hole in the Universe, and the cosmic voids that do exist aren’t hole-like at all.
It’s how successful our current theories are. Some 500 years ago, there was one scientific phenomenon that was, without controversy, extremely well-understood: the motion of the celestial objects in the sky. […]
In 1990, we only knew of the planets in our own Solar System. Today, the exoplanet count is more than 5000. Here’s what we’ve learned.
How drugs, demons, and the search for immortality gave us words we use everyday.
Gamma-ray bursts are among the most energetic cosmic events of all. On October 9, 2022, a remarkable one occurred: the brightest ever seen.
There are over 100 known elements in the periodic table. These 8 ways of making them account for every one.
A new paper reveals that the Voyager 1 spacecraft detected a constant hum coming from outside our Solar System.
We should all pause to appreciate the awe-inspiring beauty of the Universe.
‘Reductio ad absurdum’ won’t help you in an absurd Universe. Throughout history, there have been two main ways humanity has attempted to gain knowledge about the world: top-down, where we […]
