The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. [1] The concept of an expanding universe was scientifically originated by physicist Alexander Friedmann in 1922 with the mathematical derivation of the Friedmann equations.
Howard Joel Wolowitz [1] is a fictional character and one of the main protagonists on the 2007-2019 CBS television series The Big Bang Theory, portrayed by actor Simon Helberg. [2] Among the four main male characters in the show, Howard is distinctive for being an engineer —rather than a physicist —and lacking a PhD .
Jastrow was the first chairman of NASA’s Lunar Exploration Committee, which established the scientific goals for the exploration of the Moon during the Apollo lunar landings. [2] Jastrow was a public figure, prolific author and commentator on a range of topics including the space program, astronomy, earth science, and national security issues.
(By the way, don't Google "Apollo 11 images" unless you're prepared to sort through pages of fake moon landing conspiracy websites.) The most famous one is this iconic picture of Aldrin below.
The history of the Big Bang theory began with the Big Bang's development from observations and theoretical considerations. Much of the theoretical work in cosmology now involves extensions and refinements to the basic Big Bang model. The theory itself was originally formalised by Father Georges Lemaître in 1927. [1]
Artist's depiction of a collision between two planetary bodies. Such an impact between Earth and a Mars-sized object likely formed the Moon.. The giant-impact hypothesis, sometimes called the Theia Impact, is an astrogeology hypothesis for the formation of the Moon first proposed in 1946 by Canadian geologist Reginald Daly.
Comparison of the evolution of the universe under Alfvén–Klein cosmology and the Big Bang theory. [1]Plasma cosmology is a non-standard cosmology whose central postulate is that the dynamics of ionized gases and plasmas play important, if not dominant, roles in the physics of the universe at interstellar and intergalactic scales.
Moon landing deniers say there's clear photographic evidence of this, and point out that because there's no breeze on the moon, this must be fake. Apollo 11astronaut Edwin Buzz Aldrin, on the Moon ...
