The twin paradox doesn't seem to make logical sense according to special relativity. This is because:
It is only a thought experiment, and can't actually happen
It only happens at the quantum scale
The twins aren't both experiencing relative motion
The twins aren't both in inertial reference frames
Using Ho = 20.8 km/s/Mly and assuming the expansion rate has been
constant, find out how long the universe has been expanding.
According to the Big Bang Theory, order from earliest to latest, the sequence of events that are thought to have taken place at the beginning of the Universe. If statement A is first, B is second, etc. then enter ABCDEF.A) The universe becomes transparent releasing the photons of the Cosmic Microwave Background.B) Most carbon and oxygen in the Universe is produced.C) Inflation occurs.D) Hydrogen and Helium are synthesized.E) The symmetry of the four forces is broken and gravity becomes a separate force.F) Protons and anti-protons form.

- Describe some possible futures for the universe that scientists have come up with. What property of the universe determines which of these possibilities is the correct one?arrow_forwardGalaxies are found in the “walls” of huge voids; very few galaxies are found in the voids themselves. The text says that the structure of filaments and voids has been present in the universe since shortly after the expansion began 13.8 billion years ago. In science, we always have to check to see whether some conclusion is contradicted by any other information we have. In this case, we can ask whether the voids would have filled up with galaxies in roughly 14 billion years. Observations show that in addition to the motion associated with the expansion of the universe, the galaxies in the walls of the voids are moving in random directions at typical speeds of 300 km/s. At least some of them will be moving into the voids. How far into the void will a galaxy move in 14 billion years? Is it a reasonable hypothesis that the voids have existed for 14 billion years?arrow_forwardb) Explain why the temperature of the cosmic background radiation is 2.725 K, and how this temperature evolves over time.arrow_forward

The principle relies on Hubble's results that the universe appears to be the same in all directions (aka it is Question Blank 1 of 2) {hint: one word} and that any large region of space at a given distance from us appears like any other large region of space at a similar distance from us (aka it is Question Blank 2 of 2) {hint: one word}arrow_forward
