Scientists suggest the universe may be 'pixelated'

Researchers have said that humans don't yet fully understand the 'guts' of spacetime and suggested the universe is 'pixelated'.

Researchers are on a quest to link quantum gravity with the world we live in, and have suggested the universe, or spacetime, consists of individual "pixels".

A new press blurb outlines a team of researchers coming together to conduct a new experiment that will attempt to link the conventional laws of general relativity established by Albert Einstein with the world of quantum physics. These two realms of physics are yet to be unified in one cohesive theory, and Rana Adhikari, professor of physics at Caltech, and fellow colleagues believe that the universe is made of incredible small units described as a "spacetime pixel".

"A spacetime pixel is so small that if you were to enlarge things so that it becomes the size of a grain of sand, then atoms would be as large as galaxies," explains Adhikari. The researchers believe that discovering these "pixels" would allow for the unification of the two theories and answer the big question of whether gravity and spacetime can be broken down into individual components when observed on the smallest scales.

"If I drop my coffee mug and it falls, I'd like to think that's gravity. But, in the same way that temperature is not 'real' but describes how a bunch of molecules are vibrating, spacetime might not be a real thing. It may be that something that arises out of the pixelation of spacetime has just been given the name gravity because we don't yet understand what the guts of spacetime are," says Adhikari.

Jak joined the TweakTown team in 2017 and has since reviewed 100s of new tech products and kept us informed daily on the latest science and space news. Jak's love for science, space, and technology, and, more specifically, PC gaming, began at 10 years old. It was the day his dad showed him how to play Age of Empires on an old Compaq PC. Ever since that day, Jak fell in love with games and the progression of the technology industry in all its forms. Instead of typical FPS, Jak holds a very special spot in his heart for RTS games.
