American physicist John Wheeler put forward a striking hypothesis that our universe could be part of a huge ‘teapot’, with each bubble representing a separate world.
According to this theory, space and time are not homogeneous as a result of the Big Bang. They resemble foam, with the bubbles continually expanding and eventually bursting. The energy released during this process creates new ‘bubble worlds’.
Scientists say this chain reaction continues to this day.
“Every bubble world contains a vacuum and dark energy that causes small bubbles to quickly collapse and larger bubbles to expand,” explains science writer Simon Whistler.
These universes can be very different from each other. Some of them may have completely different laws of physics, some may be empty, and some may have stars and galaxies that resemble the stars and galaxies we observe.
This suggests that among the infinite number of worlds there can exist a world identical to ours.
“Our doppelgängers reading this text right now may be living in parallel universes,” Whistler says.
Although it is not yet possible to prove the ‘bubble’ theory, it has become one of the most intriguing hypotheses about parallel worlds. Scientists continue to explore this concept and develop new theories to explain the mystery of our universe and its potentially infinite twins.
