According to very real and totally verifiable scientific research, we might live in a multiverse. No, really. The same research that revealed the first-ever direct evidence of Big Bang inflation earlier this week also suggests the presence of alternate universes.
The new research also lends credence to the idea of a multiverse. This theory posits that, when the universe grew exponentially in the first tiny fraction of a second after the Big Bang, some parts of space-time expanded more quickly than others. This could have created "bubbles" of space-time that then developed into other universes. The known universe has its own laws of physics, while other universes could have different laws, according to the multiverse concept.
