Why do scientist study distant galaxies to learn about early galaxy's?

If you look at a distant galaxy, the light from the galaxy has travelled for perhaps a hundred million years, a billion years, or up to an age close to the age of the Universe (13 billion years or so), depending on the galaxy's distance. Thus, the light you see shows you how the Universe was billions of years ago.

Do all galaxies outside local group have red shifts?
Yes. Also, the size of the red-shift for all distant galaxies is directly proportional to their distance from us. This means that the space between us and all distant galaxies is expanding. Thus, Einstein's (initial) view that our Universe has been eternally stable in the location of matter must be false. No surprise that he referred to his early view as his "greatest blunder."
Why do astronomers think that quasars represent an early stage of galactic evolution?
There are more quasars in faraway galaxies, i.e., in the distant past.There are more quasars in faraway galaxies, i.e., in the distant past.There are more quasars in faraway galaxies, i.e., in the distant past.There are more quasars in faraway galaxies, i.e., in the distant past.
How can you see the past looking through a telescope at a distant object?
Scientist investigate the early universe by observing objects that are extremely far away in space.Beause it takes time for light to travel through space,looking through a telescope is like looking back in time one travels. Looking at distant galaxies evolve through time and perhaps what caused them to form in the first place.Scientiiist have already found some very strange looking objects in the Early universe.
When was Distant Early Warning - song - created?
Distant Early Warning - song - was created in 1984.
How do astronomers find out about changes in galaxies over time?
Astronomers can watch galaxies that are far away. Since the light takes billions of years to reach us from the farthest known galaxies, they would be watching galaxies in the early Universe. It turns out, from such observations, that the Universe is changing.
What causes the light in galaxies?
A galaxy is made up of hundreds of billions of stars (suns). The light from the galaxies comes mainly from those stars.However, in early galaxies, a much larger amount of energy was released from the quasar - currently believed to be the gigantic black hole in the center of galaxies.
The scientist who proved the existence of galaxies other than the Milky Way was who?
Mister Edwin Hubble did just that, before the 1920's, many astronomers thought that our galaxy included everyobject in space, in 1924 Edwin Hubble proved that other galaxies existed beyond the milky way
What is the difference between a home signal and a distant signal?
The distant signal is the "early warning" indicator for the home signal, it's used to give an early indication to the driver of what to expect when he arives at the home signal.
What is a scientist that stidies early humans?
