19) If the universe is accelerating, it will expand forever. 20) If we learn that the universe is a recollapsing universe, it will mean that the universe is presently contracting, rather than expanding as generally believed. The universe is expanding outward. Origins and Structure of the Universe Quiz.
This simply means that the universe does not expand into infinity becuase there is sufficient matter and gravity to reverse the expansion of the universe. How will the universe end?
The next possible universe is a closed universe.
The critical-density universe has an age of exactly two-thirds \(T_0\), where \(T_0\) is the age of the empty universe. There is so much curvature in this universe that the dimensions actually curve back into themselves, much like a circle or sphere. Answer the following questions by selecting an answer choice and writing the letter next to each number (1 pt. 21) One possible ingredient of dark matter is known as WIMPs, or weakly interacting massive particles. Current evidence also indicates the universe is not closed. The universe is getting smaller every day. This lesson will describe three models of the universe, including closed, open, and flat, as well as critical density and which model is most likely the correct one. The universe contracts and expands on a regular basis. Universes that will someday begin to contract have ages less than two-thirds \(T_0\). Eliot regarding the end of the world. This has caused cosmologists to abandon the … each). Which of the following statements is true? At the critical density (curve 3), the universe can just barely expand forever. A red marks objects too dark or not dense enough to be solid bodies, a question mark the smaller bodies consistent with being differentiated (the question of current equilibrium was not addressed). "Not with a bang but with a whimper," wrote the American poet T.S. A Accelerating B Coasting C Critical D Recollapsing Chapter 18 Dark Matter and from ISP 205 at Michigan State University Grundy et al. did not determine which bodies were dwarf planets, but rather which could not be. Theoretically, the cyclic universe could not [vague] be reconciled with the second law of thermodynamics: entropy would build up from oscillation to oscillation and cause heat death.
