does the universe have an edge or a center quizlet


Like the surface of a sphere has no center or edges.

What is the Universe expanding into? B. Even then it would not have a center or edges. Does the universe have a center or an edge?

Remember now, we are not talking about boundaries, for this is … But the Universe might be finite. A beginning point in time. Properties of the Expanding Universe. Learn vocabulary, terms, and more with flashcards, games, and other study tools. A) 2.27 million years B) 1.43 billion years C) 13.8 billion years D) 1,380 billion years 12. The shape of the Universe is best described as. d. The Flat Universe is most likely correct.
Why does the observable universe have an "edge"? Not 10 times the stars or mass, those numbers have stayed the same. It would have no edges then. When you login with your CWL, UBC does not share any traceable data about you with edX. No Edge, No Center -- Exploring the Shape of Our Universe. d. An edge. A cosmological redshift is a shift in the wavelength of received light from distant objects such that the wavelength of the light we are seeing is … Does the Universe have a center or edges?

e. The shape of a doughnut. Start studying AST 109 Practice Final. However, edX does require you to create an account on their servers. Think about this for a moment: If the Universe is infinite, it has unlimited volume; if the Universe is finite, it has a limited, measurable volume. We don’t know. 11.

Well, our universe does have an edge — that is, if by "our universe," you mean the observable universe. The cosmic background radiation, left over after the Big Bang of the universe and pervading all observable space, has an effective blackbody temperature of approximately Credit: Universe Today. What is the cosmological principle?

The universe does not have to be expanding into anything and the initial point at the time of the Big Bang did not have to exist in anything. The angles in large triangles would add up to less than 180°. The equations of the expanding universe have three possible solutions, each of which predicts a different eventual fate for the universe as a whole. We think you will have a lot of fun. b. Closed-A model of the Universe in which Space-Time is curved to meet itself and the Universe in finite. Search. The expanding universe, a new idea based on modern physics, laid to rest the paradoxes that troubled astronomers from ancient times until the early 20th Century. In a negatively-curved universe, the universe curves away from itself. What is cosmological red shift? This isn’t a problem if the Universe is infinite. For example, if you throw a bucket of dice you’ll find that about a sixth of them will be 1, about a sixth will be 2, and so on. Closed (has positive curvature) ... A center. Calculate the age of the universe if Hubble's constant, H 0, is 71 km/s/Mpc. edge.edx.org is hosted on servers in the US. Physicist: The increase of entropy is just how a scientist talks about the fact that the universe tends to do the most likely thing. a. Open- A model of the Universe in which space-time is curved in such a way that the Universe is infinite. The Milky Way is a big place, measuring up to 180,000 light years across. the cosmological principle is the notion that the distribution of matter in the universe is homogeneous and isotropic when viewed on a large enough scale. 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. You will log onto edge.edx.org using your UBC CWL by clicking the register button above.

The universe was born with the Big Bang as an unimaginably hot, dense point. It turns out the Universe has 10 times more galaxies than previously estimated – 2 trillion galaxies. A) because there are so many galaxies in the universe that every line of …

Like the positively-curved universe, there would be no center on the surface and no edge. A) at the exact center of an expanding universe, as shown by the universal expansion away from Earth in all directions B) near the edge of an expanding universe, as shown by the microwave radiation coming to Earth from the edge C) near but probably not right at the center of the universe, as shown by the fact that the edge is so far away from Earth It contains 100 to 400 billion stars spread across this enormous volume. c. Flat- A Model of the Universe in which Space-Time is not curved. Universe has no edge, no center. No. A two-dimensional analogy would look like a saddle.
