Our mission is to answer the biggest questions of all, scientifically.
What is the universe made of? How did it become the way it is today? Where did everything come from? What is the ultimate fate of the cosmos?
For most of human history, these questions had no clear answers. Today, they do. Starts With a Bang, written by Dr. Ethan Siegel, explores what we know about the universe and how we came to know it, bringing the latest discoveries in cosmology and astrophysics directly to you.

Groupthink in science isn’t a problem; it’s a myth
Scientists are notoriously resistant to new ideas. Are they falling prey to groupthink? Or are our current theories just that successful?
Amplifying the energy within a laser, over and over, won't get you an infinite amount of energy. There's a fundamental limit due to physics.
There are real concerns with long-term power generation on the Moon; nuclear could be the answer. But for NASA, will the cost be too high?
At the end of July, hundreds of scientists convened to plan NASA's upcoming astrophysics flagship mission. Will the US allow it to happen?
Two supermassive black holes on an inevitable death spiral push the limits of Einstein's relativity. New observations reveal even more.
When it comes to our Universe's origins, scientists discuss the Big Bang, cosmic inflation, and other theories. Why doesn't "God" come up?
On the largest scales, galaxies don't simply clump together, but form superclusters. Too bad they don't remain bound together.
The conversation you're having with an LLM about groundbreaking new ideas in theoretical physics is completely meritless. Here's why.
