A Night with the Stars

Professor Brian Cox takes a celebrity audience through the most challenging concepts in physics from the lecture theatre of the Royal Institution of Great Britain. With the help of fellow scientist Jim Al-Khalili and guests Simon Pegg, Sarah Millican, James May and Jonathan Ross, he shows how diamonds are made up of nothingness, and how one such precious gem in the heart of London is in communication with the largest diamond in the cosmos. He also reveals how things can be in two places at once and why everything that people can see and touch in the universe actually exists.

Producer: BBC, Danielle Peck, Andrew Cohen, Brian Cox (presenter)

Entanglement is one of the strangest consequences of quantum mechanics. After interacting in a certain way, objects become mysteriously linked, or entangled, so that what happens to one seems to affect the fate of the other. For the most part, researchers have only found signs of entanglement between tiny particles, such as ions, atoms and photons.

¿Tiene que estar hecho el universo de algo? Los prejuicios de la física clásica nos obligan a pensar que el universo tiene que estar hecho de algo, como todas las cosas macroscópicas que conocemos. Sin embargo, la física cuántica no nos permite saber si el universo está hecho de algo o no. Estas preguntas son más bien de metafísica y entre los físicos las opiniones están muy confrontadas. Para R.C. Henry no tiene sentido la pregunta ¿de qué está hecho el universo? Para A. Hobson está claro que el universo está hecho de “campos cuánticos” (que no son ni partículas, ni ondas, ni campos, pero son todas estas cosas al mismo tiempo). Para N.G. van Kampen el universo es “real” y la mecánica de Bohm es la interpretación (realista) correcta de la mecánica cuántica, según él es compatible con todos los experimentos.
Having created quantum superpositions of photons, electrons, atoms and even molecules, one of the current obsessions is to create a quantum superposition of a living thing, such as a virus. The question is how to do this and whether it makes any sense to say these things are living at all.
