Scientists have predicted that there could be an infinite number of Earths in the multiverse, each with slightly different outcomes and different lifeforms as a result. What if that were true? Could we then travel to these different earths through wormholes or some other means and visit these alternate realities? What would we find if we did? This article explores the possibility of multiple earths in the multiverse and what might happen if this were true.
The beginning of the multiverse
It’s hard to imagine what existed before there was space and time, but in a multiverse, each different universe has its own version of reality. Some scientists believe that before our universe existed there was another one (or many others) that have since been destroyed. This theory is known as the big bang, which suggests that at some point in time, all of these parallel universes collided with each other like cars in a traffic accident. As they did so, they also collided with their own versions of you. So technically speaking, you are not only alive right now on your earth—you are also alive on every earth in existence. However, it doesn’t necessarily mean that you exist on multiple earths simultaneously; rather, it means that at any given moment in time, there are multiple versions of you existing across an infinite number of universes. For example, if you were to decide whether or not to wear a blue shirt or red shirt today, then both decisions would be made simultaneously in two separate universes: one where you chose blue and one where you chose red. And chances are good that if you lived out both realities fully, they would be drastically different from each other. But because we live in such a small part of the multiverse, we don’t notice these differences around us very often. The end of life on earth: While most people assume that life on earth will continue for millions or even billions of years into the future, it may be possible for life to come to an end much sooner than expected. If a large enough meteor were to hit planet Earth, for instance, it could lead to mass extinction and wipe out almost all living creatures instantly.
Why we can’t see other universes?
All other planets, stars and galaxies are almost always too far away to be visible to our telescopes. Even if we could see them through a telescope, they would just appear as tiny points of light in most cases. It’s unlikely we will find evidence of life on any other planet in our galaxy anytime soon, but it might be possible to discover multiple universes. Scientists have long theorized that there is more than one universe out there; some even say there may be an infinite number of parallel realities in existence. Although these alternate universes can’t currently be observed, scientists have been able to calculate how many Earths should exist within each multiverse—and some believe that number is so large that it may even exceed our own universe’s total population of Earth-like planets. This has led some physicists to wonder whether there might be another version of Earth right here in our own reality, or perhaps even an entire solar system with its own planets like ours. And while it’s not likely anyone will ever stumble upon another version of Earth or solar system while exploring space, future generations may develop technology capable of detecting such worlds beyond our own reality. But what exactly would happen if someone were to discover another universe? Would we encounter beings from those alternate realities someday? Or would they remain completely invisible to us due to their location in another dimension or plane of existence? While it’s impossible to know for sure, it seems entirely possible that other versions of Earth do exist somewhere else in our own reality. After all, there are already so many different versions of ourselves walking around on our own planet at any given time!
How many are there?
It may sound like science fiction, but it’s not. Our planet is surrounded by a multiverse of parallel universes with billions of earth-like planets very much like our own. Some are more earth-like than others. They range in distance from our own universe, where conditions are ideal for life to evolve. Some are too close, and some too far away. But there could be millions upon millions of earth-like worlds out there just waiting for us to discover them. How many earths are there? That depends on who you ask. One scientist estimates 10^500 (that’s a one followed by 500 zeros). Another puts that number at 10^10^24 (that’s a one followed by ten billion trillion zeros). And these estimates are based on observable evidence. With so many other universes, anything is possible. There could be countless earths inhabited only by robots or wild animals or tiny people with giant heads. Or there might be alternate versions of ourselves living out different realities—for example, you might have married your high school sweetheart instead of your college boyfriend, which would mean your children look nothing like they do now. Maybe their names are even different! What if we could travel through time and visit all those alternate realities? Wouldn’t that be fun? It sounds crazy, but maybe it isn’t. Scientists believe there are infinite possibilities when it comes to multiple earths in the multiverse. Imagine what else we don’t know about yet! As Neil deGrasse Tyson says, The good thing about science is that it’s true whether or not you believe in it. So let your imagination run wild. There could be an infinite number of worlds out there beyond our comprehension.
Can we travel to them?
We can’t travel to parallel universes yet, but we may be able to in a few hundred years. And if that doesn’t work out, we could use mathematics to communicate with other Earths. Using what is called mathematical multiverse theory, it is possible for two worlds to exchange information through string theory or quantum mechanics. So while you won’t get to meet your alternate universe doppelgänger any time soon, there are ways you can have fun imagining all of the different ways our world and others might differ. Here are three things I wonder about multiple Earths What would happen if dinosaurs never went extinct on Earth-2? Would humans still exist on Earth-3 if Hitler had been a better public speaker? What would happen on Earth-4 if cats were actually lions in disguise? You tell me: What would happen on an alternate Earth if . . . ? Bonus points if you come up with a way we can investigate these theories using science!

Is time travel possible?
Physicists are certain that traveling backward in time is impossible, but nobody has been able to come up with a workable theory as to why it’s so. Maybe there’s an experiment that could demonstrate whether or not [time travel] was possible and we just haven’t figured it out yet, Weinstein said. But I don’t know what that experiment would be. Or maybe some sort of wormhole exists outside of our universe, and you can use that wormhole to go back in time. Nobody knows for sure. Scientists do believe it’s possible to move forward in time. Some researchers have even tried—and failed—to build machines that can achieve warp speed (also known as hyper-speed), which involves moving faster than light and therefore going into future. If a device did succeed, physicists would consider it proof of time travel into the future; such a machine would be capable of sending information into its own past by traveling through space-time at more than 186,000 miles per second (the speed of light). This type of time travel might be possible thanks to Einstein’s general relativity, although scientists still aren’t exactly sure how it works. One idea is that black holes bend space-time and create tunnels between two points in time. Another idea is that particles may exist that transmit information faster than light does, allowing them to send messages from one point in space-time to another point in space-time without violating Einstein’s laws of relativity.
Connecting our worlds today
Technology has grown so sophisticated that we can now send probes to Mars, explore distant galaxies using satellite imagery, or even see microscopic organisms on our own skin. As our technology continues to advance at a rapid pace, there’s no telling what marvels will emerge in years to come. For example, it may be possible for humans to step through an inter-dimensional portal and connect with another Earth in another universe – parallel worlds existing simultaneously but separate from each other. Could multiple universes actually exist within a multiverse? Or is it all just theoretical conjecture? Let’s take a look at some of these ideas.
To illustrate how much of an impact time dilation could have on space travel, consider visiting your friend’s house if they live farther away than you do. If you took off walking immediately after leaving home and headed straight toward your friend’s house without stopping along the way, you would arrive later than expected because time would have slowed down relative to where you were traveling. This is similar to what happens when we look at distant stars or galaxies: We see them as they existed in their past due to time dilation. And just as we can never truly know what happened between our departure from home and arrival at our friend’s house, we can never truly know what happened between two separate universes in a multiverse that may be separated by trillions of light years.
