The No Cloning Theorem

Is cloning possible? Not cloning as in Dolly the sheep, but cloning as in a Star Trek transporter? Here is the real science of it.

Do Cause and Effect Really Exist?

Why there's no such thing as cause and effect at the level of fundamental particle physics, and how our everyday experience of cause and effect arises due to entropy and the large-scale arrow of time

Why Doesn't Time Flow Backwards?

Why entropy gives rise to the arrow of time, how the initial state of the universe is responsible for the fact that we experience time now, and the ultimate heat death of the universe.

Jammed Cells Expose the Physics of Cancer

Gabriel Popkin Quanta
The subtle mechanics of densely packed cells may help explain why some cancerous tumors stay put while others break off and spread through the body.

Where Does The Mass Of A Proton Come From?

Ethan Siegel Forbes
We may be close to understanding the interactions of quarks and gluons within the nucleus of atoms, and when we do one of the longest-standing mysteries of physics, where the mass of the known matter of the universe comes from, may finally yield to humanity.

A Debate Over the Physics of Time

Dan Falk Quanta
According to our best theories of physics, the universe is a fixed block where time only appears to pass. Yet a number of physicists hope to replace this “block universe” with a physical theory of time.
