A group of prominent scientists shares how research has changed them.

There's a big difference between the notions of 'false vacuum' and 'true vacuum' states. Here's why we don't want to live in the former.

Headlines have blared that quasar ticking confirms that time passed more slowly in the early Universe. That's not how any of this works.

The concept of ‘relativistic mass’ has been around almost as long as relativity has. But is it a reasonable way to make sense of things?

“It is healthy and normal to be afraid of death."

The first observational evidence showing the Universe is expanding is 100 years old now: in 2023. Here's the story of its 100th anniversary.

A next-generation LHC++ could cost $100 billion. Here's why such a machine could end up being a massive waste of money.

Nothing lives forever, at least, not in the physical Universe. But relativity allows us to get closer than ever, from one perspective.

All the things that surround and compose us didn't always exist. But describing their origin depends on what 'nothing' means.

Billions of years ago, the ever-increasing entropy must've been much lower: the past hypothesis. Here's how cosmic inflation solves it.

Nature may not allow us full access to the weirdness of quantum mechanics.

From physics and alchemy to theology and eschatology, Isaac Newton’s research was rooted in a personal pursuit of the Divine.

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.

Like Dua Lipa, he had to create new rules.

It's literally the one and only trick that separates top-notch physicists from crackpots, dropouts, and those who can't cut the mustard.

For some reason, when we talk about the age of stars, galaxies, and the Universe, we use "years" to measure time. Can we do better?

There’s a lot left to understand, ponder, and investigate. And there always will be. For hundreds of thousands of years — nearly all of human history — we had no definitive answers to some of […]

When you don't have enough clues to bring your detective story to a close, you should expect that your educated guesses will all be wrong.

Our greatest tool for exploring the world inside atoms and molecules, and specifically electron transitions, just won 2023's Nobel Prize.

From the Big Bang to dark energy, knowledge of the cosmos has sped up in the past century — but big questions linger.

Successful alpha leadership is more about caring and healing than dog-eat-dog supremacy.

From high school through the professional ranks, physicists never tire of Newton's second law.

Dive into a realm where time, space, and even reality itself are put into question.

Though ultimately incorrect, the ancient Greek philosophers blazed a conceptual trail for humankind to understand the nature of reality.

It is time to give the Russian cosmologist the credit he deserves.

Ever since the start of the hot Big Bang, time ticks forward as the Universe expands. But could time ever run backward, instead?

This is especially true for three key groups.

To answer any physical question, you must ask the Universe itself. But what happens when the answers aren't around anymore?

Whether you’re a leader looking to ramp up team output or just trying to improve your skill set, hard work alone is not enough.
