As far as we currently know, there is a single expanding blob of spacetime speckled with trillions of galaxies – that’s our Universe. If there are others, we have no compelling evidence for their existence.
The Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) is home to many interdisciplinary projects which benefit from the synergy of a wide range of expertise available at the institute. One such project is the study of black holes that could have formed in the early universe, before stars and galaxies were born.
Chances are there’s another you, reading this article in another universe, except you’re dressed like a clown and drinking maple syrup from a shoe.
If the “mirrorverse” exists, upcoming experiments involving subatomic particles could reveal it.
Questions about whether other universes might exist as part of a larger Multiverse, and if they could harbor life, are burning issues in modern cosmology. Now, new research — published in two papers in the Monthly Notices of the Royal Astronomical Society — has shown that life could potentially be common throughout the Multiverse, if it exists; and the key to this is dark energy, a form of energy that naturally permeates all space and tends to increase the rate of expansion of the Universe.
There’s a battle going on at the edge of the universe, but it’s getting fought right here on Earth.
“Any sufficiently advanced hyper-dimensional creature will appear in our 3D world as background noise, unidentifiable, and indistinguishable from nature”
In other words, quantum mechanics dictates that the world we see is just one of an infinite number of possibilities.
If all these universes emerged from the same Big Bang, then they’re likely sitting together in a row, vibrating.
