Ask Astro: What causes the pattern of diffraction spikes in astronomical images?

The diffraction spikes so familiar to us in space images are an intrinsic property of the telescope. Reflecting telescopes have two mirrors: a large primary and a smaller secondary. Light hits the ...

Photons collide in the void: Quantum simulation creates light out of nothing

Physicists have managed to simulate a strange quantum phenomenon where light appears to arise from empty space a concept that until now has only existed in theory. Using cutting-edge simulations, ...

Of Course We’re Living in a Simulation

The best theory physicists have for the birth of the universe makes no sense. It goes like this: In the beginning—the very, if not quite veriest, beginning—there’s something called quantum foam. It’s ...
