The Big Bang
THE BIG BANG
How did the universe begin?
8
How many planets are in our solar system?
Milky Way
Vintergatan
What galaxy do we live on?
Asteroids - Large rocks found mostly in the asteroid belt
Comet - Formed of ice and dust in the kuiper belt and oort cloud
Meteoroid - Fragment of an asteroid or comet
What are differences between Asteroids, Comets and Meteoroids?
It is a spectrum that is comprised of the range of wavelengths or frequencies over which electromagnetic radiation exists.
All the different wavelengths of light.
What is the electromagnetic Spectrum?
Hydrogen and Helium
What were the first atoms form from the big bang?
Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune
What are the planets in our solar system in order from the sun?
125,000 light-years across
How large is our galaxy?
Tale away from the sun because of the solar winds
What way does the comet tail face and why?
1. Chemical composition of stars
2. Temperature, colour or energy in the universe
3. Distance of other celestial bodies
What can Scientists study using the electromagnetic spectrum in regards to space?
Heat radiation left over from the big bang that fills the universe.
How is Cosmic Microwave Background Radiation evidence of the Big Bang?
Inner planets are smaller rocky closer to the sun and have 1-2 moons (MVEM)
Outer planets larger formed of ice and gas further from the sun and have many moons (JSUN)
What are the differences between the inner and outer planets?
Gravity is so strong not even light can escape
What is a Black Hole?
Meteoroid: is a rock smaller that 100m across in space
Meteor: When a meteoroid crosses through the atmosphere it burns as a meteor.
Meteorite: if a meteor hit the Earth’s surface it is called a meteorite.
What is the difference between a meteoroid, meteor and meteorite?
Use the speed of light to measure the time it take to travel, calculate the distance
9 trillion light-years
How can we measure in light years?
and
How far is one light year?
As objects move away their wavelength is stretch out resulting in a “colour shift”. The light wave leaving was initially towards the blue spectrum (shorter wavelength) as it travels further distances its wavelength is stretched out and moves towards the red spectrum. This proves that if things are moving away they must have been close at one point. The universe is EXPANDING!
How is redshift proof of the big bang?
Use the electromagnetic spectrum or wavelengths
Ceres, Pluto, Makemake, Haumea and Eris
What are the dwarf planets in our Solar System?
The largest type of black hole
What is a supermassive Black Hole?
Gaseous clouds called Nebulae
What is the first stage of a star's life cycle?
Ptolemy's model of the universe
Geocentric = Earth at the center
Copernicus model of the universe
Heliocentric = Sun at the center
Lemaitre’s Development of the universe
The big bang
Galileo Galilei
Telescope - scientific discovery
What are the different theories about the Universe?
13.7- 13.8 Billion years ago
When did the SUPERFAST INFLATION take place? (First stage of the Big Bang)
Jupiter
Which is the largest planet of our solar system?
Andromeda galaxy
What is the closest big galaxy close to the Milky Way?
Supernova
What happens to a red supergiant?
The curvature of the universe, caused by massive bodies, which determines the path that objects travel.
What is gravity /gravitational field?
