The multiverse has been the topic of multiple recent films, such as Dr Strange in the Multiverse of Madness and Everything Everywhere All At Once: but what does science know about the multiverse?
Scientists have come up with a number of theories about the multiverse.
The evolution of the cosmos after the Big Bang.
Some argue the Big Bang was a rebirth rather than a birth.
Could God travel faster than the speed of light?
If God could break the laws of physics, why haven’t we seen any evidence of the laws ever being broken in the universe?
A quantum experiment raises deeply philosophical questions about the fundamental nature of reality.
How unique is our universe?

New research on parallel universes forces cosmologists to come to an uncomfortable conclusion.
We may not live in an infinite ‘multiverse’ of parallel universes after all.

The idea that we live in a ‘multiverse’ made up of an infinite number of parallel universes has long been considered a possibility.

A new book explores some of the big questions of why the universe exists and why it seems fine-tuned for life.
Like a cosmic roulette wheel, we exist because of a very lucky combination of factors.
If some of the laws of physics were only infinitesimally different, we would simply not exist. It almost looks like the universe itself was built for life. But how can that be?
Scientists are searching for collisions between different ‘universe bubbles’ in the cosmic microwave background.
The idea that our universe is just one in a ‘multiverse’ of parallel universes is increasingly gathering attention from cosmologists. But can we ever test the theory?
If there’s a multiverse out there can we see it?
The recent BICEP2 observations – of swirls in the polarisation of the cosmic microwave background – have been proclaimed as many things, from evidence of the Big Bang and gravitational waves to something…
