The key problem with the dark matter hypothesis is that nobody knows what form dark matter might take.
With a telescope at just the right distance from the Sun, we could use its gravity to enhance and magnify a potentially inhabited planet.
Not even Einstein immediately knew the power of the equations he gave us.
Unless you confront your theory with what’s actually out there in the Universe, you’re playing in the sandbox, not engaging in science.
The great hope is that beyond the indirect, astrophysical evidence we have today, we’ll someday detect it directly. But what if we can’t?
There are a wide variety of theoretical studies that call our Standard Model of cosmology into question. Here’s what they really mean.
The record-breaking transmission could revolutionize deep space communication.
No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?
Your life’s memories could, in principle, be stored in the universe’s structure.
Some of them have survived the wilds of space for billions of years.
Was it the enormous magnitude of the quake, or is the problem with the buildings?
Early on, only matter and radiation were important for the expanding Universe. After a few billion years, dark energy changed everything.
The emergence of life in the universe is as certain as the emergence of matter, gravity, and the stars. Life is the universe developing a memory, and our chemical detection system could find it.
Quantum mechanics has taught us that even empty space contains energy. “Negative energy” is the state of having less energy than empty space.
Explore how the study of exoplanets is transforming our understanding of ocean formation.
In Einstein’s relativity and the Standard Model, we only have three spatial dimensions. But there could be more, and many think there are.
The Big Bang theory is not threatened, but astrophysicists have some explaining to do.
Astronomer Adam Frank reflects on some responses to his recent appearance on the Lex Fridman Podcast.
Time gets a little strange as you approach the speed of light.
A recent experiment challenges the leading dark matter theory and hints at new directions for uncovering one of the Universe’s biggest mysteries.
From the Big Bang to black holes, singularities are hard to avoid. The math definitely predicts them, but are they truly, physically real?
By probing the Universe on atomic scales and smaller, we can reveal the entirety of the Standard Model, and with it, the quantum Universe.
If an asteroid hadn’t killed off the dinosaurs, humans would almost certainly have never walked the Earth.
The first observational evidence showing the Universe is expanding is 100 years old now: in 2023. Here’s the story of its 100th anniversary.
Perhaps the most well-known equation in all of physics is Einstein’s E = mc². Does mass or energy increase, then, near the speed of light?
No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?
