The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

In this video, we derive the catenary curve using physics and calculus, explaining how a hanging cable reaches equilibrium under gravity. Step-by-step reasoning connects forces, differential equations ...

In this video, we derive the speed required for a stable circular orbit around Earth using Newton’s law of gravitation and centripetal force. You’ll see how orbital speed depends on radius, why low ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

Why the universe is expanding faster and faster remains one of the biggest open questions in physics. Current theories cannot ...

Scientists propose a new gravity theory using Friedmann equations. Their model explains the universe’s accelerating expansion ...

For centuries, the principle of symmetry has guided physicists towards more fundamental truths, but now a slew of shocking ...

Ahead of F1's 2026 reset, Ross Brawn has tagged his GP 001, with its innovative double-diffuser, as one of his 'favourite car ...

On the ISS, viruses can still infect bacteria, but the process slows and pushes both organisms to evolve along different ...

Or is there some even more subtle message being conveyed by the sequence of Cork suburbs being used? Why Mahon and then ...
