13,2 billion x 3 million?
The gap grows at the rate of 3 million light years ps faster than light with the fact of 13,7 billion LIGHT years for age of universe
How do you best compare the amount of empty space in the universe to the amount of space galaxies occupy?
The amount of empty space in the Universe, between galaxies, is many times larger than the amount of space occupied by galaxies. This ratio depends on what part of the Universe you are looking at. For example, our galaxy has a diameter of about 100,000 light-years; the closest larger galaxy (M31) is at a distance of about 2.5 million light-years. However, that's just the Local Group; from the Local Group to another galaxy cluster, there is even more empty space.
How can we know how some parts of the universe looked a million years ago?
Light takes time to travel, so light reaching us from a million light years away has taken that long to travel to us. We see what it looked like when the light left.
How large is everything in the universe?
Everything in the universe have different size. The smallest thing ever is the photon particle, and it is so small that nobody has been able to find it's exact size. The greatest thing in the universe is the great wall- a great sheet of galaxies which is 500 million light years long and 16 million light years thick.
What is the size in square miles of the Universe?
First, you would measure the diameter of the Universe in miles, or its volume in cubic miles; but what would you want to measure in square miles?Second, the size of the Universe is not currently known. The observable Universe has a radius of about 46 billion light-years. Convert that to kilometers or miles if you like. One light-year is about 10 million million kilometers. But the entire Universe is probably much, much bigger.First, you would measure the diameter of the Universe in miles, or its volume in cubic miles; but what would you want to measure in square miles?Second, the size of the Universe is not currently known.

How large is empty space?
This is the same question as how big is the universe. The size of the universe is determined by how far light would travel in the years since the Big Bang. So it is a sphere of 13.7 light-years radius. We can't see all the way to the edge, but pretty close.
If flying at light speed for an Eon is it possible to go beyond the universe?
The universe is about 90 billion light years across. An eon is about 550 million years. Flying at the speed of light for 550 million years you would travel 550 million light years, less than 1% of the distance across the known universe. So, probably not. It would make no difference how long you travel at light speed. If you travel for a billion trillion eons, you would still not pass through the boundries of the universe. For one thing, you would have a serious problem timing your journey, since for you a trip of any length would seem instantaneous.
How many years is the 1.5million light years?
1.5 million light-years is equivalent to the distance that light travels in 1.5 million years.
What is the BFB2004 VV 29 3094 galaxy?
The BFB2004 VV 29 127 galaxy (one of the background galaxies of the Tadpole Galaxy) is a spiral galaxy 6000 million light-years (redshift of 0.66) from Earth in the Draco constellation, and is 100,000 light-years in diameter (same size as the Milky Way), and contains about 100 billion stars (same number of stars as the Milky Way). It emitted its light 6000 million years ago when the universe was about 8000 million years old.
What is the PGC 3080366 galaxy?
The PGC 3080366 galaxy is a spiral galaxy 600 million light-years from Earth (redshift of 0.044) in the Cetus constellation, and is 100,000 light-years in diameter (same size as the Milky Way), and contains about 100 billion stars (same number of stars as the Milky Way). It emitted its light 600 million years ago when the universe was 13,100 million years old.
What is the NGC 514 galaxy?
The NGC 514 galaxy is a spiral galaxy 100 million light-years (redshift of 0.008) from Earth in the Pisces constellation, and is 100,000 light-years (the same size as the Milky Way) in diameter, and contains about 100 billion stars (same number of stars as the Milky Way). It emitted its light 100 million years ago, when the universe was 13,600 million years old.
What is the NGC 3370 galaxy?
The NGC 3370 galaxy is a spiral galaxy 100 million light-years (redshift of 0.008) from Earth in the Leo constellation, and is 100,000 light-years (the same size as the Milky Way) in diameter, and contains about 100 billion stars (same number of stars as the Milky Way). It emitted its light 100 million years ago, when the universe was 13,600 million years old.
