Stars
An average star surrounded by 8 major planets
Sun
What is the Big Bang Theory?
The Big Bang Theory is a model explaining exactly how the universe began.
What have the galaxies been doing since the big bang?
The galaxies have been expanding/spreading
What is light?
A form of energy that travels as a wave
The light that we see
visible spectrum
An average size star that has burned up most of its fuel, and is in the stage before it burns out.
White Dwarf
The event that occurred when the universe emerged from this state is known as the ______ .
Big Bang
One of the evidences for the Big Bang Theory that was discovered by accident by Bell Laboratories while testing an antennae.
Cosmic Background Microwave Radiation
Does each galaxy emit their own spectrum/range of colours in a pattern? Yes or No?
Yes
The light that insects use to see with and that gives us sunburns and suntans and skin cancer?
ultraviolet light
The next stage our sun will go through after it uses up all of its hydrogen
Red Giant
All ______ of the universe, was packed together into one small, extremely dense, hot mass under pressure.
Matter
Another evidence that Edwin Hubble used to show that all galaxies were moving away from us and away from each other.
Red Shift
How can we tell an object is moving?
We can tell an object is moving by red shift
The light that rattlesnakes use to sense their prey and that Predator used to see his victims.
infrared light or radiation
A super giant star that has used up all of its fuel and has a core of iron that causes it to collapse on itself and create a gravity field so strong, not even light can escape.
Black Hole
Even after the Big Bang occured, we now know EVERYTHING about the universe. True or False?
False - Scientists CAN describe what they think occured about a fraction of a sec. after the Big Bang, but not everything was revealed after the explosion.
The only elements formed in the Big Bang
Hydrogen and Helium
What RED SHIFT?
Red shift refers to the shift in a wavelength of light to longer wavelengths of light
Shows that a star of galaxy is moving away from the earth or we are moving away from the star or galaxy.
Red Shift
A super giant star that explodes and creates all the natural occurring elements and provides a way for new stars and planets to be created.
Supernova
The Big Bang Theory is the ONLY way that the beginning of the universe can be explained. True or False?
False - There are many ways but in the past, there were people's beliefs, but each kind of model helps us understand how the world began.
In what state did the universe emerge from?
It emerged form a state of density and pressure (Big Bang)
Do ALL galaxies show red shift? Yes or No?
Yes
Shows that a star or galaxy is moving towards the earth or the earth is moving towards a star or galaxy.
Blue Shift
