Quantum Experiment Could Finally Reveal The Elusive Gravity Particle

Posted by in categories: particle physics, quantum physics

The graviton – a hypothetical particle that carries the force of gravity – has eluded detection for over a century. But now physicists have designed an experimental setup that could in theory detect these tiny quantum objects.

In the same way individual particles called photons are force carriers for the electromagnetic field, gravitational fields could theoretically have its own force-carrying particles called gravitons.

The problem is, they interact so weakly that they’ve never been detected, and some physicists believe they never will.

This super-dense cosmic ‘pasta’ is the strongest material in the Universe

Posted by in categories: materials, particle physics

By the ‘strength’ of a material, we usually mean the degree to which it can withstand deformation by an external force. So, the strongest materials are generally those with high densities because the closer the constituent atoms are, the greater the resistance they have to further compression.

How Subjective is Entropy Really?

Posted by in categories: computing, particle physics

Physics stack exchange has recently been debating the question of the subjectivity of entropy.

I recommend Andrew Steane answer.


I’m a computer scientist doing some research that touches on basic concepts in statistical mechanics: macrostate, microstate and entropy. The way I’m currently conceiving of it is that the microstate includes all the information to perfectly the describe the state of a system, the macrostate provides some of the information, allowing you to narrow down the possibilities to a subset of states and a distribution over them, and the entropy roughly says how much information is still missing after you specify the macrostate.

CEVA & CERN: Where Edge AI and Particle Physics Intersect

Posted by in categories: internet, particle physics, robotics/AI

About 63% of the world population access the internet [Source: Statista] and a majority of them experience the internet through webpages. As such, the general population refers to the internet and the web pages interchangeably. Of course, those in the technology arena do know the difference but may or may not remember when and where the world wide web (WWW) was invented. Without its invention, the internet experience of today will not be the same.

100% of all living creatures experience something automatically and that is their “mass”, interchangeably and inaccurately referred to as “weight” by the general population. Of course, those who remember their physics know the difference. While material mass is taken for granted in general physics, there is a field of physics that tries to explain what gives materials their mass. The existence of the mass-giving field was confirmed when the Higgs boson particle was discovered.

The organization that is behind both the WWW invention and the Higgs boson discovery and many other remarkable inventions is CERN. The World Wide Web was invented in 1989 by Tim Berners-Lee while working at CERN. The existence of the mass-giving field was confirmed in 2012, when the Higgs boson particle was discovered at CERN.

Panprotopsychism: Panpsychism

Posted by in categories: neuroscience, particle physics, quantum physics

, while an interesting thought experiment, does not seem to account for the fact that many phenomena are materialistic or physical enough to have no resemblance with the qualities we typically attribute to consciousness, such as experience and motive.

Panprotopsychism, by contrast, does not require matter to be intrinsically conscious, only that it be comprised of features equaling consciousness when combined.
