WebTides and Phases The Sun also has a small tidal effect on Earth. The distance to the Sun makes the difference of force on both sides of the Earth smaller than it is due to the Moon Size of tides thus depends on the relative positions of the Sun and moon, which also determines the phase of Moon. WebJun 21, 2024 · Gravity pulls galaxies closer together; dark energy pushes them apart. Whether the universe is expanding or contracting depends on which force dominates, gravity or dark energy. Just after the Big Bang, the universe was much smaller and composed of an extremely high-energy plasma. This plasma was vastly different from anything today.
WebDec 30, 2014 · If a system (i.e. a collection of galaxies, a cluster) is gravitationally bound then it means that the gravity connecting the galaxies within that system is enough to overcome the effects of whatever it is (dark energy) that normally makes galaxies accelerate away from one another.
