How slight differences could have forever changed our cosmic history. 13.8 billion years ago, what we know today as our Universe began with the hot Big Bang. Filled with matter, antimatter […]

From time-traveling billiard balls to information-destroying black holes, the world’s got plenty of puzzles that are hard to wrap your head around.
Business leaders know they must prepare for technological upheavals in the years ahead. But keeping up-to-date on new technologies—to say nothing of understanding their complexities and forecasting those shifts—is an […]
“We can build AI scientists that are better than we are… these systems can be superhuman,” says the FutureHouse co-founder.
Nobel Laureate Roger Penrose, famed for his work on black holes, claims we’ve seen evidence from a prior Universe. Only, we haven’t.
The brilliant mind who discovered the spacetime solution for rotating black holes claims singularities don’t physically exist. Is he right?
Researchers from MIT invent a highly accurate clock using quantum entanglement that can lead to new physics.
If we waited long enough, would even protons themselves decay? The far future stability of the Universe depends on it.
“Imagination is more important than knowledge” is often taken to mean that your conceptions outweigh what’s real. That’s not what he said.
If the Universe is expanding, and the expansion is accelerating, what does that tell us about the cause of the expanding Universe?
Many people out there, including scientists, claim to have discovered a series of game-changing revolutions. Here’s why we don’t buy it.
Most of us only ever see a fraction of a full rainbow: an arc. But optically, a full rainbow makes a complete circle. Physics explains why.
Just by observing the tiny amount of deuterium left over from the Big Bang, we can determine that dark matter and dark energy must exist.
Hubble showed us what our modern day Universe looks like. JWST’s big goal was to teach us how the Universe grew up. Here’s where we are now.
The Universe is supposed to be the same everywhere and in all directions. So what’s that giant “cold spot” doing out there?
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 act of observing doesn’t just determine a previously indeterminate state, but can destroy information, too. Imagine that you’re a scientist attempting to understand reality at a fundamental level. How […]
If the electromagnetic and weak forces unify to make the electroweak force, maybe, at higher energies, something even grander happens?
From before the Big Bang to the present day, the Universe goes through many eras. Dark energy heralds the final one.
Physicists create quantum entanglement, making two distant objects behave as one.
Breakthrough technology uses multiplexing entanglement to make an ultra-secure quantum internet.
Science has come a long way since Mary Shelley penned “Frankenstein.” But we still grapple with the same questions.
Often viewed as a theoretical, calculational tool only, the Lamb Shift proved their existence. If you spend enough time listening to theoretical physicists, it starts to sound like there are […]
We cannot deduce laws about a higher level of complexity by starting with a lower level of complexity. Here, reductionism meets a brick wall.
Before there were planets, stars, and galaxies, before even neutral atoms or stable protons, there was the Big Bang. How did we prove it?
New experiments find weird quantum activity in supercold gas.
They’re not just a theoretical prediction of quantum gravity. They should be detectable, too. The Universe, if you look at it closely and carefully enough, is fundamentally quantum in nature. […]
And can we devise an experiment to tell, even when we aren’t looking? One of the most bizarre aspects of quantum physics is that the fundamental entities that make up the […]
Galactic archaeology has uncovered a spectacular find: the Milky Way already existed more than 13 billion years ago.
Even before the Big Bang, energetic radiation was always present. When it comes to the physical Universe, the notion of “nothing” may truly be possible only in theory, not in […]
