Cosmology
Cards in this deck (7)
- 1Big Bang TheoryEDWIN HUBBLE: He proposed the idea that space was constantly expanding and therefore the universe is constantly expanding and decreasing in density. because the space between the galaxies was expanding, there were moving away from each other.
- 2Steady State modelFRED HOYLE: said that the universe was always the same size, and is not expanding. New matter is formed which pushes galaxies apart while keeping density of universe constant. REJECTED
- 3Doppler effectThe change in frequency or colour as the sound/colour waves are compressed or stretched due to the direction of the travelling object.
- 4Red ShiftMoving away (angry - storm off)
- 5Blue ShiftMoving Towards (too cool - everyone wants ya)
- 6JovianGas giants - Large Mass and size. low density. No solid surface, With many moons and strong gravitational pull
- 7TerrestrialSmall size, Inner rocky planet. Fewer moons and a high density.
