It's one of the most compelling questions you could possibly ask, one that humanity has been asking since basically the beginning of time: What's beyond the known limits What's past the edge of our maps The ultimate version of this question is, What lies outside the boundary of the universe
To answer the question of what's outside the universe, we first need to define exactly what we mean by \"universe.\" If you take it to mean literally all the things that could possibly exist in all of space and time, then there can't be anything outside the universe. Even if you imagine the universe to have some finite size, and you imagine something outside that volume, then whatever is outside also has to be included in the universe.
If the universe is infinite in size, you don't really need to worry about this conundrum. The universe, being all there is, is infinitely big and has no edge, so there's no outside to even talk about.
Oh, sure, there's an outside to our observable patch of the universe. The cosmos is only so old, and light only travels so fast. So, in the history of the universe, we haven't received light from every single galaxy. The current width of the observable universe is about 90 billion light-years. And presumably, beyond that boundary, there's a bunch of other random stars and galaxies.
Cosmologists aren't sure if the universe is infinitely big or just extremely large. To measure the universe, astronomers instead look at its curvature. The geometric curve on large scales of the universe tells us about its overall shape. If the universe is perfectly geometrically flat, then it can be infinite. If it's curved, like Earth's surface, then it has finite volume.
Current observations and measurements of the curvature of the universe indicate that it is almost perfectly flat. You might think this means the universe is infinite. But it's not that simple. Even in the case of a flat universe, the cosmos doesn't have to be infinitely big. Take, for example, the surface of a cylinder. It is geometrically flat, because parallel lines drawn on the surface remain parallel (that's one of the definitions of \"flatness\"), and yet it has a finite size. The same could be true of the universe: It could be completely flat yet closed in on itself.
But even if the universe is finite, it doesn't necessarily mean there is an edge or an outside. It could be that our three-dimensional universe is embedded in some larger, multidimensional construct. That's perfectly fine and is indeed a part of some exotic models of physics. But currently, we have no way of testing that, and it doesn't really affect the day-to-day operations of the cosmos.
When you imagine the universe, you might think of a giant ball that's filled with stars, galaxies and all sorts of interesting astrophysical objects. You may imagine how it looks from the outside, like an astronaut views Earth from a serene orbit above.
But the universe doesn't need that outside perspective in order to exist. The universe simply is. It is entirely mathematically self-consistent to define a three-dimensional universe without requiring an outside to that universe. When you imagine the universe as a ball floating in the middle of nothing, you're playing a mental trick on yourself that the mathematics does not require.
If all this sounds complicated and confusing, don't worry. The entire point of developing sophisticated mathematics is to have tools that give us the ability to grapple with concepts beyond what we can imagine. And that's one of the powers of modern cosmology: It allows us to study the unimaginable.
My book, \"Your Place in the Universe,\" explores our evolving conception of the cosmos and our place within it, and is a great place to start your own journey (opens in new tab). And the Harvard-Smithsonian Center for Astrophysics maintains a FAQ about the universe, which you can find here (opens in new tab).
She and Alberto bond over memories of Gabriel, as the father talks about how he realizes what Nina meant to her. Alberto knew that Nina needed a kidney donor, and he, too, had decided to undergo a compatibility test. The result was positive, and Alberto decided to proceed with the process. The possibility delights Nina. When she asked Alberto the reason why he chose to donate his kidney, he explained that the medical field is about giving comfort, and since he knew he could provide that to Nina, he went ahead with it.After the procedure, Nina decides to perform with the Symphony Orchestra finally. She dedicates a song to Gabriel, reminding the love of her life. He taught her to be optimistic. Even though he was not with her at the moment, she believed that he was watching over her and that their love was, indeed, beyond the universe.
Wizards of the Coast announced that on occasion they could utilize the treatment from the Ikoria Godzilla cards (existing Magic cards skinned with the alternate universe). But mostly, the sets would be like The Walking Dead (alternate universe cards that stand on their own). According to Mark Rosewater, it was not feasible to have a Magic version for every new UB card, but R&D can make Magic versions of any UB card if the need arises. The other way around, Universes Beyond may feature straight reprints from original Magic sets with the same card name (but new art) and same mechanical cards but with a new name. It depends on how well the name fits the IP.
Large UB sets like The Lord of the Rings: Tales of Middle-Earth won't receive 1:1 in-multiverse versions, but R&D reserves the right to make in-universe versions if the need arises. If a Universes Beyond card with an IP-specific creature type (e.g. astartes) would be rebranded, it would receive a brand new creature type in the Magic version. The and would be one-for-one in the rules much like the names of the Godzilla skinned cards.
When I grow up I want to be an astronomer and be the first person to discover life on a new planet. This is my dream because I find the universe so interesting and I am willing to think beyond Earth. The universe is full of surprises and I want to uncover them.
I like going to school and learning. We studied the moon phases and tides and on Earth. I would like to be able to learn more complex subjects about the universe. For example, I want to learn about dark matter and black holes. To learn more about this subject outside of school I often get books about our solar system and the universe. I'd also really like to visit the National Air and Space Museum at the Smithsonian Institute in Washington D.C. and the McDonald Observatory. The education I need for this job is going to be a Ph.D. and will take \"5-7 years with courses in astrophysics, stellar and planetary physics and more\" according to Study.com.
This career is important now and will continue to be in the future because pollution is destroying our planet and we may need a new place to live someday. Also, technology is continuing to progress and that is making it easier to discover if life on other planets exists. Our curiosity is never-ending and we are able to discover more now than ever before and we want to know if we are the only form of life in the observable universe.
The birth of the universe may have began with what is called the Big Bang. This gigantic explosion of pure energy started approximately 13.4 billion years ago. The image above shows a brief explanation of the time frame related to the expansion of the universe after the big bang. There has been no explanation of where the energy came from and how the explosion started. All we know is what happened after.
The giant webs of galaxies we see in space were caused by tiny quantum size fluctuations in the energy released by the big bang in the first milliseconds to seconds of the big bang. As the universe expanded, these small fluctuations caused large patterns to evolve as things cooled and atoms were created. Through gravitational interactions of many particles pulling the hydrogen and helium gasses together, stars began to form. As stars formed, their gravity pulled them together to create galaxies. These newly formed galaxies kept the initial patterns caused by the quantum fluctuations, just in larger, more compact areas. Now we see the universe as a web of galaxies with clusters, strands and voids.
The \"life\" of the universe as it's seen over the past 13.4 billion years is represented in the pictures above progressing from youngest (furthest) and oldest (closest). From left to right, the images show very young galaxies at a time when the universe was less than a billion years old. As we look closer in the next image we see galaxies that are about 12 billion light years away. They appear as small dots in the images but represent the furthest galaxies we've seen so far. These images have changed how we have estimated when galaxies began to form, which has been shown to be very early in the life of the universe. The middle image shows a galaxy cluster with bright quasars that have been gravitationally lensed. They are older than the galaxies in the second image but younger than those seen in the foreground in the center image. Looking further at the fourth image, we see galaxies even closer to us and older in age. We begin to see many shapes of galaxies formed as they have interacted over the past several billion years. In the final image, we see a spiral galaxy which is close to what our Milky Way is, in terms of evolutionary age and is also very close.
What lies beyond the universe We are not sure but can theorize what lies beyond the universe that we know. Outside the bounds of our universe may lie a \"super\" universe. Space outside space that extends infinitely into what our little bubble of a universe may expand into forever. Lying hundreds of billions of light years from us could be other island universes much like our own. But why can't we see them It's a possibility that they are so far away that by the time their light reaches us, it may have lost so much energy that we cannot detect it, or our universe may end by the time it reaches us. 59ce067264
