Physics research drives the long-term arc of technology and our understanding of the universe. This hub covers quantum mechanics, particle accelerator results, fusion energy progress, condensed matter discoveries, and the intersection of physics with computing.

We have confirmed more than 6,000 planets around other stars. We have directly photographed about 98 of them. Here is how the other 98% were found, and why that method leaves our map of the galaxy badly distorted.

Quantum computers are not faster computers. They are machines for a short list of specific problems — and the list of proven, useful wins is still empty. Here is what the evidence actually supports.

The world's biggest machine ended its third run in June 2026 and began a four-year upgrade to the High-Luminosity LHC. Here's the current state of the Large Hadron Collider and the road to 2030.

Fission splits heavy atoms; fusion joins light ones. Here's how the two nuclear reactions really differ — in energy, fuel, waste, safety, and which one powers the future.
ScienceComparison
Classical computers use bits; quantum computers use qubits. Here's how the two really differ — in how they work, what they're good at, and why one won't replace the other.

A photon is a quantum — but not every quantum is a photon. Here's the real difference between the two, in plain English, and why people mix them up.

Light weighs nothing, yet it warms your skin, powers solar panels, and even pushes spacecraft. Here's the physics of how a massless photon carries energy — and momentum.

On December 5, 2022, 192 laser beams fired at a target smaller than a peppercorn — and produced more energy than they carried. Here's exactly how the National Ignition Facility achieved the fusion milestone physicists had chased for 70 years.

Quantum computers threaten the encryption that secures the internet — but it's more nuanced than the headlines. What actually breaks, what survives, why 'harvest now, decrypt later' makes it urgent today, and how the world is already fighting back.
ScienceGuide
Quantum entanglement explained in plain English — why Einstein hated it, what 'spooky action at a distance' actually means, why it can't send faster-than-light messages, and how experiments proved it real.
ScienceAnalysis
Our standard model of the cosmos has worked beautifully for decades. Now precision data — DESI's evolving dark energy and the Hubble tension — are cracking it. What's going on, in 2026.

What is a photon, really? A clear guide to the quantum particle of light — its bizarre properties, whether you can 'split' one, and the photonic tech reshaping computing and security in 2026.
Quantum computing uses the principles of quantum mechanics — superposition and entanglement — to perform certain calculations exponentially faster than classical computers.
Nuclear fusion is the process that powers the Sun: two light atomic nuclei are forced together to form a heavier one, releasing enormous energy. Recreating it on Earth — as at the National Ignition Facility — is one of physics' biggest engineering challenges and a potential source of clean, abundant energy.
Experiments show light produces wave-like interference yet also arrives in discrete packets called photons. This wave–particle duality is a fundamental feature of quantum mechanics, not a limitation of our instruments — light genuinely behaves as both, depending on how it is observed.
