Many physicists believe that entanglement is the essence of quantum weirdness — and some now suspect that it may also be the essence of space-time geometry.

A doorway to another universe,  large enough to swallow a spaceship, may exist at the centre of the Milky Way.  Wormholes (artists's impression pictured) are thought to allow travel between distant points in space and time

Wormhole in the Milky Way could link to another UNIVERSE

Einstein's general theory of relativity suggests, among other things, that masses in space distort the geometry of space-time. In addition, moving objects emit waves of gravitational radiation that carry energy away into space.

What is space?  In the best theory of physics on this topic – Einstein’s theory of general relativity – it is a component of space-time, but difficult to envision with our naive intuitions. (So, the observer is in 'the present moment', which is all that exists.)

From dark energy and string theory to the end of the Universe, these are the unanswered cosmic conundra that are still baffling scientists.

•"Tout autour de nous - l'ensemble tridimensionnelle monde physique - est une illusion née de l'information codée ailleurs, sur une puce à deux dimensions." Certains chercheurs croient que la physique ne sera pas complète jusqu'à ce qu'il puisse expliquer non seulement le comportement de l'espace et temps, mais où ces entités sont issus. Et pour ce faire, les théories physiques vont avoir à obtenir beaucoup plus étrange•
