Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

My theory may be able to inform us whether these exotic systems can be a way of structuring things so this quantum state could be more permanent," says Buca. The method is a bit like a road map that ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

Everyone has their favourite example of a trick that reliably gets a certain job done, even if they don’t really understand why. Back in the day, it might have been slapping the top of your television ...

Time has always seemed like the one thing physics could count on. Matter changes, stars die, particles flicker in and out, ...

The question of how gravity interacts with the quantum world has long perplexed physicists, but a non-quantum theory of space ...

Overview: We built this list around a documented selection process, not personal taste, weighing factors such as authority, teaching quality, and how well each ...
