Are We Expanding With The Universe?

The video discusses the concept of cosmic expansion in relation to bound objects such as galaxies, planets, and people. The universe itself is expanding, meaning that space between galaxies is stretching over time. However, this expansion doesn't affect locally bound structures due to the strength of other forces. Gravity, electromagnetic forces, and nuclear forces effectively prevent the expansion of galaxies, solar systems, planets, and human bodies. The effects of cosmic expansion are only observable at extremely large scales, such as between clusters of galaxies, where gravitational attraction is weaker. While the universe is expanding, any objects that are held together by forces stronger than the effect of cosmic expansion remain unaffected. Galaxies, solar systems, and atoms stay intact because the forces holding them together overpower the influence of expansion. At these smaller scales, the universe's expansion is not significant enough to break gravitational or molecular bonds. This is why we do not expand along with the universe — the fundamental forces at play in our local environments dominate over the force driving cosmic expansion Perks & Membership:    / @ah-documentary   Subscribe Here: ‪@AH-Documentary‬ #AHDocumentary #Cosmology #Astronomy #UniverseExpansion #Einstein #Hubble #SpaceScience #DarkEnergy #Galaxies #MilkyWay #Spacetime #Astrophysics #Universe OUTLINE: 00:00:00 Are We Expanding With The Universe? 00:01:23 Einstein's Gravity And Minkowski Spacetime Of Special Relativity 00:03:00 Black Hole | De Sitter Space | Comic Inflation 00:04:12 Redshifts And Blueshifts 00:05:40 In 1923, When Edwin Hubble Made A Groundbreaking Discovery... 00:06:56 We’ve Learned That The Universe Today Is Made Of... 00:08:45 But Not Everything Expands 00:09:56 Why Are These Galaxies Not Obeying Hubble’s Law?
