Dark matter has eluded us for many decades. Even our most advanced particle colliders and sophisticated underground detectors have come up short. But...

The universe is expanding and that expansion is accelerating under the power of dark energy and eventually all matter and energy will be dispersed...

According to quantum physics, the universe should have collapsed on itself in the instant after the Big Bang due to all particles being 100 million...

They say fusion is 50 years away, no matter when you ask. Then why are billions suddenly being pumped into fusion startups? Yes to train LLMs, but...

How did the universe begin? How can something come from nothing? One way to “solve” this most difficult of philosophical conundrums is to...

Did you know that many of us have up to 4% neanderthal DNA? And that 100% of your DNA may come from outer space? No joke. The biochemistry that...

Giant space rocks are definitely going to hit the Earth again. We actually do know how to deflect them, but only if we find them and correctly assess...

Planet Earth is the jewel of the solar system—the shimmery blue oceans, the verdant green forests, the wispy whimsical cloud formations. Saturn...

At one-one-thousandth of a second after the Big Bang, the great annihilation event should have wiped out all matter, leaving a universe of only...

The vacuum of space is a chaotic sea of quantum fluctuations. Some have said that this vacuum energy can be harvested to build our future starship...

Around 2 billion years ago, life had plateaued in complexity, ruined the atmosphere, and was on the verge of self-annihilation. But then something...

The biggest news in cosmology in recent years is that the mysterious universe-accelerating entity we call dark energy may be fading away. The...

Big things are made of smaller things, and those smaller things are made of smaller things still. That’s reductionism in a nutshell, and...

Did God have any choice in creating the world? So asked Albert Einstein. He was being poetic. What he really meant, was whether the universe could...

The molecular basis of all life is mysteriously asymmetric, only using molecules on one side of what should be the equivalent mirrored pairs. The...

The multiverse pops out of quite a few theories in physics, and has been proposed as a solution to certain vexing problems. But it’s also been...

In 1987, Steven Weinberg wrote a cute little paper entitled “Anthropic Bound on the Cosmological Constant”. I say cute little paper...

One of the most important reasons we go to space is to know our own planet better. Today I'm going to tell you about an orbiting facility that...

To observe the quantum nature of gravity and of spacetime itself, we need a particle collider the size of the solar system. Or we could just physics...

Recent findings have brought us closer than we’ve ever been to confirming life beyond the Earth. As we wait for confirmation or otherwise,...

Does quantum mechanics allow the future to retroactively influence the past, as in the infamous delayed choice quantum eraser experiment? How about...

Join Stephen Hawking and other renowned thinkers as they explore the revolutionary new ideas that have evolved since the publication of his...

How We Invented the World is the ultimate action-packed, hi-energy, landmark series that examines the four inventions that define the modern world -...

Hawking gives us the ultimate guide to the universe, a ripping yarn based on real science, spanning the whole of space and time -- from the nature of...

The Bell System Science Series consists of nine television specials made for the AT&T Corporation that were originally broadcast in color between...
