- 3 unhealthy habits that are making your breasts sag
The article highlights three unhealthy habits that accelerate breast sagging, noting that while aging and gravity are unavoidable, these habits exacerbate the process.
- Hidden supermassive black hole pairs may finally have a visible signal
Scientists proposed a new method to detect tightly bound supermassive black hole pairs by observing stars that flash repeatedly due to gravitational magnification. The timing and brightness of these bursts could reveal black holes spiraling toward a collision.
- Entanglement Builds Space-Time. Now "Magic" Gives It Gravity
The article discusses how quantum entanglement constructs space-time and introduces a new concept called 'magic' that may explain how gravity emerges from this framework. It references a Quanta Magazine article and Hacker News comments on the topic.
- Entanglement Builds Space-Time. Now “Magic” Gives It Gravity.
John Archibald Wheeler's 1973 description of space and matter interaction, encapsulating general relativity, highlights a challenge for modern theorists regarding space-time and gravity.
- 'One of the great unresolved embarrassments of physics': It's been 340 years since Newton and scientists still haven't solved the secret of gravity
The article discusses the ongoing mystery of gravity, 340 years after Newton's work, with the gravitational constant (G) remaining unsolved despite centuries of scientific effort.
- First quantum grandfather clock could probe where gravity comes from
Researchers have designed a quantum version of a pendulum clock. It could shed light on timekeeping in the quantum realm and potentially probe the origins of gravity.
- Does gravity create reality? A shocking path to a theory of everything
A revised approach to quantum mechanics incorporating gravity may lead to a unified theory of everything, addressing physicists' long-standing goal. The article suggests this could reveal the fundamental uncertainty of time.
- Physicists just found a tiny flaw in time itself
Physicists have discovered a potential flaw in time's precision linked to quantum mechanics and gravity. New research suggests spontaneous 'collapse' processes may blur time, revealing a hidden limit to its accuracy and offering a path to unify quantum physics with gravity.
- Artemis astronaut Jeremy Hansen on what he missed about gravity: "Nothing"
Artemis astronaut Jeremy Hansen humorously stated he missed nothing about gravity while in space, noting that despite the challenges of microgravity, the experience is 'just so worth it.'
- Artemis astronauts on readjusting to gravity, capturing photos from space: "It's spectacular"
Artemis astronauts Christina Koch and Reid Wiseman shared experiences of readjusting to Earth's gravity and capturing photos during their lunar mission. Wiseman described the space imagery as 'spectacular' in an interview with CBS Mornings.
- Scientists catch antimatter “atom” acting like a wave for the first time
Scientists observed wave-like interference in positronium, an exotic atom composed of an electron and a positron, marking the first time antimatter has exhibited such quantum behavior. This discovery reinforces quantum mechanics principles and paves the way for experiments testing gravity's effect on antimatter.
