What is Big Bang Theory
- Believed to have occurred 13,7billion years ago and may explain how the universe was made
- it started off as a singularity which existed before time, space and anything existed
- it gradually got hotter, until it exploded
What’s significant about observations at Mount Wilson observatory in 1929
- it confirmed the Big Bang Theory due to observations that the universe was expanding
- this was concluded by the observations of Hubble which saw the light of distant galaxies getting redder which may be explained by the stretching of the light waves and thus, meaning they are moving away from us.
What’s steady state theory
whilst the universe is expanding, the density of the universe doesn’t change due to continuous creation of matter— so no end or beginning?
What loop theory
proposes, that in each cycle, the universe refills with hot, dense matter and radiation which brings a universe of expansion and cooling. After 14 billion years, the expansion accelerates, as we can observe, and after trillions of years, the matter and radiation are almost completely dissipated and the expansion sops. An energy field pervades the universe and creates new matter and radiation, continuing the cycle
What’s Heisenberg uncertainty principle?
we cant know both the position and speed of a particle, such as a photon or electron, with perfect accuracy and certainty
What’s kochen-specker theorem
Kochen-Specker theorem states that the outcome obtained depends on the context at that time and can’t be predicted.
Therefore, the universe isn’t changeless
What is fallacy of composition?
this is when it is assumed that parts of a whole will be the same properties as the whole. For example: objects in the universe show evidence of design, so there must be a Designer. Therefore, the universe has a designer
What are empirical observations?
Evidence is through observations of the universe
