The gravitational constant, affectionally known as 'Big G,' is one of the most fundamental constants of our universe. Its value describes the strength of the gravitational force acting on two masses separated by a given distance.

Katia Moskvitch got the idea for a podcast after her precocious son, who loved scrolling through YouTube science videos and has been programming in Python since he was six, kept peppering her with big questions about the origins of life and the universe.

The generation of coherent extreme ultraviolet and X-ray photons by high harmonic generation from solid targets relies on the formation of a steep electron density gradient tuned by the leading edge of a relativistically intense laser pulse interacting with a bulk, solid-density target.

Orion is hurtling toward where the Moon will be, not where it is-like a quarterback leading his receiver-they've already got a slightly different angle on the Moon than we do here on Earth.

The film then reversed the trick and zoomed back toward that Chicago couple and into their bodies to show the equally breathtaking world of our insides, down to the molecular and atomic level.

"I've done a lot of time-dilated travel." This statement encapsulates the essence of Grace's journey, highlighting the profound effects of traveling at speeds approaching light, where time for the traveler slows down significantly compared to those remaining on Earth.

There's just so much to do. So, the advances that we've gotten over the last five to ten years have been spectacular. We love the tools. We use them every day. But the question is, is this the whole universe of things that needs to happen? And we thought about it very carefully and our answer was no, there's a lot more to do.

I believe in discipline. I do want to—as we say—live long and prosper. There were so many Sunday mornings I woke up groaning: I'll never do that again, after debauched nights at college spent on the beer bus. I've learned that, if you take care of yourself, mother nature will be good to you.

Light is one aspect of the Universe that, for most people, holds a deep and noticeable value in everyday life, helping them to navigate, learn from, and connect with the world around them. Yet it's not particularly difficult to imagine life without it. After all, many nonhuman animals live in lightless environments. However, as Gideon Koekoek, an associate professor of physics in the research group Gravitational Waves and Fundamental Physics

"It is something humanity has never done before, it is historic," says Stefan Ulmer, a physicist at Heinrich Heine University Düsseldorf, and member of the team.

A core question we want to understand is where did matter come from. And then, if you know about antimatter, it's natural to ask, why is that not here? The process is not understood and we are hunting for clues as to why it happened, says Dr Christian Smorra, a physicist on the Baryon Antibaryon Symmetry Experiment (Base) at Cern.

In the vacuum of space, the amount of debris-spent rocket stages, splintered satellites, micrometeoroids- numbers in the millions, all zooming about, often at 17,000 mph speeds. They're also constantly hitting each other in a tsuris of exponential littering. Most of these pieces are tiny, and many are not anywhere near the altitude of the ISS. But the area isn't completely clean.

We now recognize that even ideas like "when" and "where" are subject to the laws of Einstein's relativity, and that in relativity, space and time are not absolute quantities, but rather are relative to each and every unique observer.

A supercooled microscopic ferromagnet proves the existence of gyroscopic magnetic behaviour that has been long sought by physicists.

In the run-up to this year's Winter Olympics, and even as the Games have got underway, a scandal has been brewing: allegedly, some competitive ski jumpers may have artificially enlarged their crotch area by injecting their genitals with engorging chemicals or stuffing their underwear to create bigger bulges. The apparent reason: to alter their suit measurementsski jumpsuits are precisely tailored to jumpers' bodiesand, reportedly, to gain a boost in jumps. The allegations, first reported by a German media outlet and since dubbed Penisgate, have caught not only the Internet's attention but also the World Anti-Doping Agency's eye, although no athletes have been implicated by name.

Now say you want to run some modest AI stuff. That's a bigger job, so let's scale up our cubical computer with edges twice as long as before. That would make the volume eight times larger (2 3), so we could have eight times as many processors, and we need eight times as much power input-2,400 watts. However, the surface area is only four times (2 2) larger, so the radiative power would be about 4,000 watts.
