The Awesome Universe
Transcript of The Awesome Universe
2nd Period The Milky Way Galaxy You Are Here! A barred spiral galaxy.
120,000 light years across.
13 Billion years old.
Part of the Virgo Super cluster. Stars Their Birth Begins in a Nebula Baby Stars Stars often come in multiples.
Blue stars are the hottest while "cold"stars are more reddish. Temperature is analogous to Color
Stars are classified by a specific category scale.
Are always in a constant gravitational conflict.
Their life usually ends as either a white drawn or as a black hole Special Stars Magnetars
Have an immensely strong magnetic field and it can't control it.
Neutron Stars are a type of star which is extremely massive.
When a very heavy star collapsed rapidly, the protons and electrons are fused to form only neutrons.
Are a possible result at the end of a star's life.
The laws of physics break down in a black hole. Gravitational Lens Dilation The Mystery of Dark Matter and Dark Energy A Representation of the Universe Jelly- Bean Style Everything we "see" makes up only about 4% of the observable universe. The Theory of Relativity Newton's Law of Gravitation Newton's Law of Universal Gravitation was useful on Earth, but was useless for understanding motion and forces in a void such as space . It also didn't explain where gravity came from or why it occurred. Albert Eienstein proposed a Theory of Relativity which explained gravity and time as relative, rather that absolute. His theory relates energy with mass and also the speed of light.
This explains that mass distorts space, which causes gravity. It also ties space and time together into a single entity called "spacetime"
It also explains how gravity or speed can affect the passage of time. So time (and space) can be relativistic. E = m x c 2 speed of light mass energy Thanks for Watching Quasars Are a special type of galaxies that shoot energy particles (electrons) from their centers. Even Stranger Physics: The Science of Atoms or Quantum Physics The study of the behaviors of subatomic and atomic particles. Has strange rules like:
"Superposition" or "Entanglement" But what is the Theory of Relativity? Galaxies E= MC^2! Sun His theory led to the prediction and discovery of black holes and prediction of white holes Consist of billions of stars (200,000,000,000)
Has four categories. Elliptical Spiral or Barred Spiral Irregular Large Magellanic Cloud Galaxy We have no idea what the rest of the universe is! "Dark Matter" makes up about 23% while "Dark Energy" is about 73% A Revolution in Physics "Ring" Galaxy Quantum Levitation Except the speed of light
