If we discover how to connect quantum mechanics with general relativity weâll pretty much win physics. There are multiple theories that claim to do this, but itâs notoriously difficult to test them. They seem to require absurd experiments like a particle collider the size of a galaxy. Or we could try to physics smarter, instead of physicsing harder. Letâs talk about some ideas for quantum gravity experiments that can be done on a non-galaxy-sized lab bench, and in some cases already have been done.

The Physics and Philosophy of Time Travel
What if everything we know about time is merely an illusion? Could find a way out of it, by breaking the construct of how the universe progresses? And so, would it be possible to break the natural flow of time?

Oracle Unveils Worldâs First Zettascale AI Supercomputer with 131K NVIDIA Blackwell GPUs
Elon Musk is not smiling: Oracle and Elon Muskâs AI startup xAI recently ended talks on a potential $10 billion cloud computing deal, with xAI opting to build its own data center in Memphis, Tennessee.
At the time, Musk emphasised the need for speed and control over its own infrastructure. âOur fundamental competitiveness depends on being faster than any other AI company. This is the only way to catch up,â he added.
XAI is constructing its own AI data center with 100,000 NVIDIA chips. It claimed that it will be the worldâs most powerful AI training cluster, marking a significant shift in strategy from cloud reliance to full infrastructure ownership.
Simulation theory: why The Matrix may be closer to fact than fiction
âThe Matrixâ may have been right all along. The idea that we are all living in a virtual simulation of reality formed the basis of the 1999 cult film, and now some philosophers and an increasing number of scientists are coming round to the idea it might actually be true.
Simulation theory, as it is known, is a âtheoretical hypothesis that says what people perceive as reality is actually an advanced, hyper-realistic computer simulation, possibly overseen by a higher beingâ, said BuiltIn.
