With launch, deployment, calibration, and science operations about to commence, here are 10 facts that are absolutely true.
The Big Theoretical Physics Problem At The Center Of The ‘Muon g-2’ Puzzle In early April, 2021, the experimental physics community announced an enormous victory: they had measured the muon’s magnetic […]
The last image puts it all in perspective. Compared to what we find in our Solar System, galaxies are truly enormous. The Sun may be 109 times the diameter of […]
Just because an idea is fashionable doesn’t mean it’s relevant for our Universe. One of the greatest unsolved puzzles in all of science is dark energy. The Universe isn’t just […]
Why power generated through nuclear fusion will be the future, but not the present, solution to humanity’s energy needs.
Why do we deprive students of the historical and cultural context of science?
We might live in a quantum Universe, but we’ll violate the principle of relativity if space is discrete. If you try and divide matter into smaller and smaller chunks, you’ll […]
The Kalam cosmological argument asserts that everything that exists has a cause, and what caused the Universe? It’s got to be God.
The theoretical reasons to expect it are compelling, but the technology required to detect it is unfathomable. All throughout our galaxy, millions of black holes of a variety of masses […]
A Mercury-bound spacecraft’s noisy flyby of our home planet.
Once only dark energy remains, empty space still won’t be completely empty. Imagine, if you dare, the very end of the Universe. The stars — past, present, and future — have all burned out. […]
As this map of Bouguer’s gravity anomaly shows, the pull of the earth varies considerably by region.
As the first Friedmann equation celebrates its 99th anniversary, it remains the one equation to describe our entire universe.
No matter how controversial or politicized our world becomes, science remains humanity’s best tool for figuring out how things work.
Even in the most exotic scenario imaginable, they still can’t remain stable in the Earth’s interior. It’s well known among scientists that if you submit even the most nonsensical paper […]
Many still cling to the idea that we live in a deterministic Universe, despite the nature of quantum physics. Now, the “least spooky” interpretation no longer works.
Targeting a signaling pathway in mice helped them retain muscle and bone mass aboard the International Space Station, according to a new study.
There are two fundamentally different ways of measuring the Universe’s expansion. They disagree. “Early dark energy” might save us.
One silver lining of the pandemic: The value of common sense, facts and rational decisions increases.
Using a laboratory model, scientists get a nice Jovian surprise.
A 2020 space mission wants to use zero gravity to disable some of the hardest cancers to fight.
Based on the atoms that they’re made out of, the innermost planet should always be the densest. Here’s why Earth beats Mercury, hands down.
Few scientific ideas have been as polarizing as string theory. There are good reasons to both love it and hate it. String theory is perhaps the most controversial big idea in […]
It had long seemed impossible that supermassive black holes could grow to such enormous sizes. But the biggest problem is now solved.
Even with leap years and long-term planning, our calendar won’t be good forever. Here’s why, and how to fix it.
We know it couldn’t have began from a singularity. So how small could it have been at the absolute minimum?
New mathematics have shown that lines of energy can be used to describe the universe.
Just 13.8 billion years after the hot Big Bang, we can see 46.1 billion light-years away in all directions. Doesn’t that violate…something?
Researchers propose a gravity-based system for long-term energy storage.
