Scientists are notoriously resistant to new ideas. Are they falling prey to groupthink? Or are our current theories just that successful?

In 2017, a kilonova sent light and gravitational waves across the Universe. Here on Earth, there was a 1.7 second signal arrival delay. Why?
Astronomers possibly solve the mystery of how the enormous Oort cloud, with over 100 billion comet-like objects, was formed.
Our Sun will continue to grow, becoming a red giant and then a planetary nebula. Here’s how large it will get.
Astronomers claim to have found structures so large, they shouldn’t exist. With such biased, incomplete observations, perhaps they don’t.
Over the coming decades, over 100,000 new satellites are expected. For countless millennia, whenever we were faced with a clear, cloudless, moonless night, all of humanity was able to witness […]
Even though the leftover glow from the Big Bang creates a bath of radiation at only 2.725 K, some places in the Universe get even colder.
No. No no no. Just… no. The JWST has truly blown our scientific minds, but it’s a pure crackpot idea that the Big Bang is now disproven.
A conversation with an advanced alien species is likely to be simple and to take 1,000 years. It might also be dangerous.
In 2017, we detected gold being forged in a neutron star-neutron star merger. Now, in 2024, the amounts created simply don’t add up.
Whether they’re gas giants or rocky planets makes all the difference for life. Over the past 30 years, we went from not knowing if there were planets like ours around other […]
The study shows that it’s possible to map the wildly subjective psychedelic experiences to specific brain regions.
One image can give over 100 times the data we now get from Hubble. NASA’s Hubble Space Telescope, launched in 1990, revealed the previously unseen Universe. The most distant galaxy ever […]
Today, the star-formation rate across the Universe is a mere trickle: just 3% of what it was at its peak. Here’s what it was like back then.
Astrophysicists once believed in a static Universe, containing only the Milky Way galaxy. Science definitively proved otherwise.
As early as we’ve been able to identify them, the youngest galaxies seem to have large supermassive black holes. Here’s how they were made.
In all the Universe, only a few particles are eternally stable. The photon, the quantum of light, has an infinite lifetime. Or does it?
Our Solar System’s outer reaches, and what’s in them, was predicted long before the first Oort Cloud object was ever discovered.
Even with all the recent impacts we’ve seen, it might be more “foe” than “friend” to us.
Since the time of Galileo, Saturn’s rings have remained an unexplained mystery. A new idea may have finally solved the longstanding puzzle.
Atomic nuclei form in minutes. Atoms form in hundreds of thousands of years. But the “dark ages” rule thereafter, until stars finally form.
Scientific surprises, driven by experiment, are often how science advances. But more often than not, they’re just bad science.
The thrills and horrors of strange heavenly bodies condensed into one attractive snapshot.
Investments in public libraries are a long-term investment in children and communities.
We are traveling in a realm that once exclusively belonged to the gods. Space travel will force humanity to rethink everything.
There are pros and cons to sending interstellar messages to aliens that may or may not exist.
After more than two decades of precision measurements, we’ve now reached the “gold standard” for how the pieces don’t fit.
Just 12 million light-years away, the galaxies Messier 81 and 82 offer a nearby preview of the Milky Way-Andromeda merger.
The search for worlds outside our solar system has just turned up a planet, TOI-2257 b, with a truly extreme orbit.
