A. bigger than B. smaller than 2. How many galaxies are in the observable universe? Here’s the TL;DR version: the universe is expanding faster than the speed of light. The myth: You can't fold a paper in half more than eight times. The universe formed as a result of the great explosion, about 13.77 billion years ago. We do not see the whole universe except where we have light. My name is Anton and in this video, we will talk about what you would see at the edge of the universe. # 2. The observable universe is a somewhat different story. actual universe is bounded by the edge of the observable universe. Q. okstate ASTRO spring final; Shared Flashcard Set. Q. # 3. As you reach the horizon, it moves away from you, similarly for the edge of the Observable Universe. They claim the galaxies are receding at light speed. The speed of light is just that — a speed — and the universe …
Well, our universe does have an edge — that is, if by "our universe," you mean the observable universe. The size of the observable universe is determined by the number of years since the big bang. We cannot know for sure what lies beyond the enclave our instruments can detect. Title. JC’s Q: “How fast are stars at the edge of the observable universe traveling away from us?” Lambda CDM and Hubble’s expansion i.e. The observable universe is the region of the universe we can observe, defined by how far light has traveled since the Big Bang 13.8 billion years ago. The observable universe is over 13.8 billion years old. Since our observable universe is not infinite, it has an edge. Q&A Corner. # 1. To answer this, you have to realize that the speed of light is finite and fixed. The best estimate of the age of the universe as of 2013 is 13.798 ± 0.037 billion years. -This video illustrates the scaled size of our universe from quarks to the entirety of the observable universe. The actual universe is likely ______ the observable universe. ... the size of the observable universe, and is equal to the speed of light divided by the Hubble constant, so c/H: Term. The radius of the visible universe, is about 14.0 billion parsecs (about 45.7 billion light years), while the comoving distance to the edge of the observable universe is about 14.3 billion parsecs (about 46.6 billion light years), about 2% larger. The observable universe is a somewhat different story. There’s an edge to the observable universe—we can only see so far out. Same as the edge of the Earth (Uhh, I mean the horizon). Answer to 1. The radius of the visible universe, is about 14.0 billion parsecs (about 45.7 billion light years), while the comoving distance to the edge of the observable universe is about 14.3 billion parsecs (about 46.6 billion light years), about 2% larger. But this does not mean that Earth is the center of the universe. As stated in the introduction, there are two aspects to consider: its local geometry, which predominantly concerns the curvature of the universe, particularly the observable universe, and; its global geometry, which concerns the topology of the universe as a whole. Wow, there are a lot of very long answers here. The "edge" of the observable universe is A. a real Although the universe has no edges and may be infinite, the observable universe is a spherical region around Earth where light has been able to reach us since the Big Bang.
