UNDERSTAND

THE ENDOFTHEUNIVERSE

OUT OF TIME

While cosmologists agree

that the Universe will end

in billions of year s’ time,

what they’re undecided on

is how it will happen.

Currently, there are four

scenarios that have the

most support: the Big RIp

(visualised here), the Big

Bounce, the Big Freeze and

the Big Crunch.
