The anti-universe also must be running back in time for the idea to work. If this were all true, both universes would expand ...

An “anti-universe” where time runs backwards could exist next to ours, according to a new study. The theory involves the fact nature has fundamental symmetries and researchers think this could ...

In this model, the anti-universe stretches backward in time from the Big Bang, mirroring the properties of our Universe with ...

According to Kumar, his universe–anti-universe model has implications beyond just the birth of our universe—as it may shine fresh light on several long-standing cosmological puzzles.

If an anti-universe exists, it would run backward in time, before the Big Bang. Dark matter, then, could be right-handed neutrinos implied by the mirror universe.

Anti-matter is the opposite of matter, and barely exists in our universe at all. Matter and anti-matter annihilate each other on contact, creating energy. Sign up for Today's Best Articles in your ...

In this anti-universe, dark matter would be primarily made up of a new kind of neutrino, the extremely high-energy and low-density subatomic particles that carry neither a positive nor negative ...

An anti-universe running backwards in time could explain dark matter and cosmic inflation. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works ...

Seeing the universe as an object in itself, instead of a mashup of different forces and fields that each have their own interactions, gives it an anti-universe under CPT symmetry.

We may not know what an anti-universe what would look like, exactly, but we assume it would be -- well -- different. Things would be pretty much the opposite of what we expect them to be.

A wild theory suggests there may be an "anti-universe" that runs backwards in time before the Big Bang. The concept, explained in a paper accepted for publication in the journal Annals of Physics ...
