Finding life beyond our Solar System requires understanding its host planet.
In “Life As No One Knows It,” Sara Imari Walker explains why the key distinction between life and other kinds of “things” is how life uses information.
In the 1970s, James Lovelock proposed that the biosphere was not just green scruff quivering on Earth’s surface. Instead, it managed to take over the geospheres.
A perfect map is as useless as it is impossible to create.
Physicists have increasingly begun to view life as information-processing “states of matter” that require special consideration.
The future belongs to complexity.
33 years ago, the theoretical biologist Robert Rosen offered an answer to the question “Is life computable?”
The preservation and celebration of life, and not greed, should be our primary decision-making value.
In 2023, data from the James Webb Space Telescope soured hopes that TRAPPIST-1 c had an atmosphere. That disappointment might have been premature.

Even with the best technology imaginable, you’d probably never be able to exist as a consciously aware brain in a vat.
Total eclipses are a product of a strange and almost eerie cosmic coincidence — one that makes Earth an even rarer world in the galaxy and, by proxy, in the Universe.
Explore how the study of exoplanets is transforming our understanding of ocean formation.
The “first cause” problem may forever remain unsolved, as it doesn’t fit with the way we do science.
A deep dive into the chaotic journey of star formation.
Here’s the case for why science can’t keep ignoring human experience.
13.8 columnist Marcelo Gleiser reflects on his recent voyage to Earth’s last wild continent.
Human civilization has always survived periods of change. Will our rapidly evolving technological era be an exception to the rule?
In 1924, Edwin Hubble found proof that the Milky Way isn’t the only galaxy in the Universe.
Big Think columnist Adam Frank makes the case for why the 2023 video game Alan Wake 2 is a boundary-pushing piece of art.
Explore how QBism reframes science by placing the observer at the heart of quantum reality.
Millennia ago, philosophers like Anaximander grasped that nature is the ultimate recycler.
The answer is set to change in the year 2113, a recent estimate suggests.
Fire was crucial to the evolution of human technology. That’s why alien species stuck in the “oxygen bottleneck” may be forever primitive.
From how life emerged on Earth to why we dream, these unanswered questions continue to perplex scientists.
These theoretical megastructures represent one way an advanced civilization might harvest energy from stars.
Astronomers have discovered more than 5,000 confirmed exoplanets — very few of which resemble Earth.
