Some physicists think we live in a multiverse, surrounded by universes not quite like our own. What does that mean for life?

The discovery of massive, early galaxies could force scientists to rethink how the first galaxies formed after the Big Bang.
Astronomers have found that mysterious dark energy may originate in black holes.
It has been one year since the launch of the James Webb Space Telescope and six months since the first pictures were released. Astronomers are already learning unexpected things about the early universe.
An astrophysicist explains what wormholes are and how these theoretical space-time tunnels have popped up in the solutions to a set of decadesold equations.
James Webb has spotted extremely distant galaxies formed soon after the Big Bang, but are they old or young? Or is this the wrong question to ask?
It’s the oldest light in the universe.
The Hubble Space Telescope could gaze back 13.4 billion years, and with the JWST we expect to improve on this possibly to 13.55 billion years.
Time ends when the universe does.
Some argue the Big Bang was a rebirth rather than a birth.
Tracing the cosmic origin of toothpaste, scientists got a glimpse into the surprising chemistry of early galaxies.
The James Webb Space Telescope is set to launch into orbit in December 2021. Its mission is to search for the first light to ever shine in the universe.
How scientists are planning to listen to the sound of the big bang with a gravitational wave detector that would fit in a kitchen.
A small add-on to existing gravitational wave detectors could reveal what happens to matter as it becomes a black hole, a process like the big bang in reverse.
The term ‘Big Bang’ might make you think of a massive explosion. Put the thought out of your head. Rather than an explosion, it was the start of everything in the universe.
Scientists who discovered planets in far off stellar systems and the fundamentals of the Big Bang Theory have earned the 2019 Nobel Prize in Physics.
The Princeton cosmologist helped pioneer our current model of the universe and began a whole new branch of physics.
Long ago in the distant past, our entire Universe was microscopic – just like an atom – and obeyed completely different rules of cause and effect.
Helium lifts balloons and makes our voices squeak. But its supply on Earth is finite and is critical for modern industrial processes and medical imaging in hospitals. How worried should we be?
From a mysterious energy of empty space to parallel universes, cosmology’s view of ‘nothing’ is anything but boring.
