According to the current standard model of cosmology, the observable universe – containing all the billions of galaxies and trillions upon trillions of stars – is just one of an infinite number of universes existing side-by-side, like soap bubbles in a foam.
Because they are infinite, every possible history must have played out. But more than that, the number of possible histories is finite, because there have been a finite number of events with a finite number of outcomes. The number is huge, but it is finite. So this exact event, where this author writes these words and you read them, must have happened an infinite number of times.
Even more amazingly, we can work out how far away our nearest doppelganger is. It is, to put it mildly, a large distance: 10 to the power of 10 to the power of 28 meters. That number, in case you were wondering, is one followed by 10 billion billion billion zeroes

can you explain a bit about the curvature of spacetime or how it's curved?
Thanks for asking!! It’s a little difficult ti picture curved space, so I highly recommend this video, it’s phenomenal at helping you understand how gravity arises from space and time being warped//curved by matter.
I think the above video does a phenomenal job at explaining gravity in terms of warping space and time; definitely watch it. The heavier an object, the more it warps space-time; this means that time gets slowed down with heavier objects, since the space and time become more warped. You may have heard that time flows slower on the earth than it does further up from its surface; time flows faster for astronauts since they experience less of earth’s gravity (since they are further away).
This visualization was the best one I could find? but tbh it’s still hard for pretty much everybody, including the world’s best physicists, to visualize and wrap their head around. Let me know if you have any other questions or need a clarification!! Also, you might want to check out the relativity/general relativity tag on my blog if you want to see some of the other posts i’ve made.
