All scientific theories, at some level, are wrong. That’s why consensus is so vital. There are two important and common words that, when used scientifically, have a very different meaning than […]

The Big Bang is our accepted origin of the Universe. But is there another possibility? Since the mid-1960s and the discovery of the Cosmic Microwave Background, the Big Bang has […]
Forgetting them, at any step, can lead to unscientific conclusions. No one, not even the smartest among us, were competent scientists from the outset. The concept of science is simple […]
There’s no such thing as a theory that’s too beautiful to be wrong, if it doesn’t agree with experiment. The history of physics is filled with great ideas that you’ve […]
Spoiler: it isn’t the end of the Universe, and it’s not likely to lead to new evidence for the Multiverse, either. On March 14, 2018, the most famous and celebrated […]
If your favorite theory made the list, you might want to consider a new favorite to bet on. “Some people believe holding on and hanging in there are signs of great […]
One of cosmic inflation’s cofounders came out against it, calling it not even science. But it is… and so much more. “There’s no obvious reason to assume that the very same […]
Holes, lines, or even walls in space aren’t just fiction; they could actually exist! “Weakness of character is the only defect which cannot be amended.” –Francois de La Rochefoucauld The biggest lesson […]
There’s useful science to be gotten out of it, but most science that mentions it is anything but. “There is a voice inside of youThat whispers all day long,‘I feel this […]
And just what did come before — way before — the Big Bang? “We are part of the universe that has developed a remarkable ability: We can hold an image of the world in our […]
Gravity is the oldest fundamental force ever discovered. Might it not be fundamental after all? “The whole edifice of modern physics is built up on the fundamental hypothesis of the atomic […]
Before the Big Bang… after the Big Freeze… will everything look the same? “What is wild cannot be bought or sold, borrowed or copied. It is. Unmistakeable, unforgettable, unshamable, elemental as […]
And the science of how we can find it. This article is written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity and high energy physics. She also […]
If there is a quantum theory of gravity, is String Theory the only game in town? “I just think too many nice things have happened in string theory for it to […]
A live-blog event of a fabulous public lecture given by Katie Freese on the unseen components in our Universe. “If you take everything we know… it only adds up to […]
How the “hierarchy problem,” or why gravity is so much weaker than everything else, might be the key to the entire Universe. “I just think too many nice things have […]
There were two periods of exponential expansion in the Universe: one today and one long ago. Are they related? “What is wild cannot be bought or sold, borrowed or copied. […]
If String Theory has nothing to do with reality, what are our options? “I just think too many nice things have happened in string theory for it to be all […]
Is everything astonishingly simple, though? Or is this a grandiose claim that falls flat when confronted with the evidence? “My main interest is the problem of the singularity. If we […]
Can the world’s most fantastic and speculative “theory of everything” candidate shed light on the Universe’s most invisible objects? “I just think too many nice things have happened in string […]
A “speculative” theory no more; it’s had four of them confirmed. “Scientific ideas should be simple, explanatory, predictive. The inflationary multiverse as currently understood appears to have none of those […]
We don’t know the nature of either dark matter or dark energy: 95% of our Universe. Does that mean the Big Bang is in doubt? Image credit: wiseGEEK, © 2003 — 2014 […]
Sure, the Universe is expanding, and that expansion is accelerating. But beyond simply calling the cause “dark energy,” what do we know about it? Image credit: NASA, ESA, H. Teplitz […]
What every middle-to-high schooler should know. Image credit: Bayside STEM academy, via Stanford at https://ed.stanford.edu/news/new-design-thinking-curriculum-targets-middle-school-students. “Education is an admirable thing, but it is well to remember from time to time […]
What everyone should know about where our matter-and-radiation-filled Universe came from. “I don’t think at this point we have any way of knowing where the laws of physics came from. We […]
It was the most promising idea for where new physics might lie. Now that the LHC data is in, is it dead? “The revolution is not an apple that falls when […]
We normally think of the Big Bang as the very beginning of our Universe, but we now know the story goes back even before it. Here’s how. “The aim of science […]
How our best physical understanding of the early stages of the Universe — that set up the hot Big Bang — inevitably leads us to conclude that there’s a lot more than what’s merely […]
Dartmouth professor Marcelo Gleiser tackles the headache-inducing question of whether we can arrive at the end of knowledge.
What’s the Big Idea? All religions, arts and sciences are branches of the same tree.” – Albert Einstein In the latest RSA Animate production, Manuel Lima explores the power of […]
