Our Big Bang Balloon activity showed galaxies are moving away with farther galaxies are moving faster. Who discovered this phenomenon?
Hubble
Penzias
Wilson
Our Big Bang Balloon activity showed galaxies are moving away with farther galaxies are moving faster. If we rewind the data we can see extrapolate that
The universe was smaller and hotter in the past
The universe was larger and hotter in the past
The universe was larger and colder in the past
The universe was smaller and colder in the past
According to the Big Bang the Universe started with as super atom (a singular point) that contained all the ______ in the Universe today.
matter
both because E=mc^2
As the Universe expanded it started to cool and form atoms. Which equation explains how we can make atoms from energy and energy from atoms?
v=Hd
E=mc^2
v=frequency x wavelength
Which of the following is evidence for the Big Bang Theory (choose all correct answers... there's more than 1)
Galaxies are moving away from us with the farthest galaxies moving fastest
Cosmic Background Microwave Radiation
The composition of the Universe is approximately 75% H, 24% He, and trace amounts of Li.
The Universe is hotter today than it was in the past
The early Universe was too hot for atoms to form. What were the first three elements to form as it cooled?
H, He, Li
H, Be, B
Li, C, O
He, N, Fe
Today, the Cosmic Background Radiation is very cold, only 2.725 K above absolute zero, thus this radiation shines primarily in the _____________________ portion of the electromagnetic spectrum, and is invisible to the naked eye.
Microwave
Gamma Ray
Visible Light
Radio Waves
Since light travels at a constant (the same) speed across great distances, it takes a long time to reach us on Earth. Therefore, astronomers observing distant objects are looking into the past. We observe Andromeda, the nearest big galaxy, as it was about ________ because Andromeda is 2.5 million light-years away.
2.5 million years ago
2.5 years ago
2.5 thousand years ago
none of these

True
False
