Even if we agree that the universe is finite and has an edge, what is at the edge is another topic up for debate. A finite universe has a finite size that can be measured; this would be the case in a closed spherical universe. And all of me agree. By default, the term “universe” defines everything. My gut tells me that due to the fact that the Universe is temporally finite with an age of 13.8B years that there is something beyond, a cause resulting in an effect, but that is all I have. We don’t know. The non-local one is not localized in space and so would appear as a uniform homogeneous background of radiation and particles. That being said, it’s pretty much impossible for us to ever reach the end of the universe if it does exist. That’s to say its fabric, spacetime, curves back on itself in any of 18-or-so potential shapes, like a donut, or möbius strip. so Mankind just follow the path of the “evolution” like an embryo in the womb, that can’t be detected by the ultrasound in the first seven weeks though it is there, follow the path to become an awesome human! And beyond the borders of that, etc. If you go far enough in one direction, you will return to your starting point. So the answer to the question “if the universe is finite, what lies beyond” is that there is nothing beyond the universe because the universe represents everything, including things “outside” of it. thanks. In the 1800s, astronomer Heinrich Olbers claimed that the universe couldn’t be anything but finite. But because of what is NOT taught in our schools, we cannot even find the right questions! This is just another reason to believe that the universe has expanded, even beyond our exploration capabilities. If the universe is finite, what would beyond the edge of the universe be like? Namely, it is very difficult … This makes up the observable universe but is unlikely to be the full extent of space, this is just the visible part. If the Big Bang theory (with inflation, of course) is correct and all the matter/energy, both visible and dark, came into being some 13 billion years ago, then it hardly seems that this component could be infinite in size. Read ahead. The Universe can expand without there being anything outside it for it to expand into, says science writer and astrophysicist Adam Becker.He explains this mind-bending idea to BBC … Seems infinity can’t be crossed. Therefore, you have to pass an infinite number of points to reach your destination, so you never reach it. The book “Terra non firma Earth” reveals the geology, and “Big Breach Universe” on the android app store takes it to the next level from where the book leaves off. I’m referring to crossing, or perhaps I should have better said passing through, an infinity of time. 4 minutes ago. It is impossible to know what, if anything, existed before our universe. But an infinite universe has no size by definition. A lot more universe exists beyond what we are able to observe. Through extensive research, scientists concluded that the universe must have come into existence approximately 13.8 billion years ago. In another episode of Guide to Space, we talked: “how big is our Universe”. So, BIG, yes, but definitely finite. Where does all the “stuff” come from? As for what is beyond this finite Universe, that is a question raised by materialists who cannot grasp (it is very difficult to grasp) that beyond this Universe there is neither space nor time. Both possibilities have mind-bending implications. Confused by that last, “finite and unbounded”. Beyond the yellow circle is an even larger (imaginary) one containing 4.7 trillion galaxies, the maximum portion of the Universe that will be accessible to us in the far future. So, how would you test this idea just by watching the sky? Scientists have observed that the universe is doing the exact opposite of slowing its growth rate down – it’s actually accelerating! We do not know what, if anything exists beyond 15 billion light year radius from the epicenter of the Big Bang. The Universe is definitely finite but WITHIN an infinite Consciousness. What I’ve learned so far is that with every advance we can only marvel at how much we have yet to learn. The “background radiation” would include the whole spectrum, not just the microwave background, but also the X-ray background, which is surprisingly bright and uniform. Hubble discovered that galaxies were pulling away from each other, a crucial proof that the universe wasn’t static, but actually constantly expanding. I like when Fraser posts these kinds of posts. From our standpoint they are observationally superimposed. One hydrogen pile looks the same as the next to me. Galaxies “appear” to be moving further apart, but not because of a “big bang.”. A spherical universe is bound but you can go around it forever (a 3d visible universe bent around in 4d space for example.). In other words, let “c” (the speed of light) BE the “box” and let space and time be defined by that box. [The feedback “problem” of LQG is resolved if you allow a Fibonacci Tree expansion of the level of dimensionality at each crunch/bang event, starting from a single quantum event.] There is a space known as the “observable universe” which is everything that we’ve managed to explore and observe so far. They say that children are the future. First, the observable universe is the one we have size estimates for, because I repeat, we don’t even know if the entire universe is infinite or finite, so size measurements don’t make any sense. That’s an “at least” figure. http://www.facebook.com/octavian.peagu, Simply thinking – if its finite then it has to have a boundary, what is beyond that boundary then. Why 8 billion years ago the speed of the expansion of the Universe was less than it is now? Ancient Greeks were the first to start asking questions as they observed the night sky. So the question is “is our physical universe of matter and energy finite with empty space going on forever around it?” Or does our universe contain an infinite amount of matter? After many centuries of thought by some of the best minds, humanity has still not arrived at conclusive answers to these questions. Everything has a beginning and an end, it may be so distant we can’t fathom it, but it still exists. In these scenarios, you can travel forever in a straight line, and you’ll eventually wind up back where you started. The cosmological principle states that the distribution of mat… Assuming of course, that other lifeforms haven’t discovered infinite pencil technology, or there’s a pocket dimension containing only pencils. Observers internal to such a universe will observe it to be open and infinite, even though externally the bubble universe is finite and geometrically closed. Time itself can be finite. The concept of infinity is certainly difficult to grasp for the normal human brain, though one may say that, even with an edge (as blurry as it is), the universe is practically infinite. That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago. The universe is infinite.
