The universe is big.
Our sun is one star, and part of our "Milky Way" galaxy.
The Milky Way contains a lot of starts. About
There are more galaxies in our universe: hundreds of billions of galaxies in the observable universe! Typical galaxies range from dwarfs with ten million (10^7) stars, up to giants with a hundred trillion (10^14) stars.
NGC 4414 is a typical spiral galaxy in the constellation Coma Berenices, is about 55,000 light-years in diameter and approximately 60 million light-years away from Earth.
We can't see how the universe is now, blind as for what is going on out there. Our eyes and out telescopes can sense a part of the electro magnetic spectrum, information that travels with the speed of light. In the relatively tiny worlds we live in, the speed of light is extremely fast, almost instantly from the source to the eye. But relative to a space filled with galaxies, the speed of light goes so slow that is almost seems to stand still.
Everything we see when looking into space, is very old information.
How old? Here's a list.
The moon = 1.3 seconds old
Mars = at least 54.6 million km, thus at least ((54.6*1000000*1000)/299792458)/60 = 3 minutes old. The furthest Mars can be from the Earth is 401 million km, then the information is ((401*1000000*1000)/299792458)/60 = 22.3 minutes old.
Our sun, a star = 8.3 minutes old.
The nearest other star (Proxima Centauri) = about 4.2 years old.
The nearest galaxy, a satellite of the Milky Way; the Canis Major Dwarf Galaxy = about 25000 years old.
The farthest objects we can see (a gamma-ray burst) = 13.1 billion years old.
So, maybe we'll one day have telescopes that can give us a close up view on a planet from the nearest galaxy. What we can see from there is from about 25000 years ago! Maybe there are species on that planet now that can look at us with similar telescopes. They will see us, also like it was about 25000 years ago. How was Earth like, that many years ago?! Cultural evolution began somewhere between 8500 and 7000 BC, so 25000 years ago… they would see us living in caves, Homo sapiens, hardly recognizable as how humans are today.
Before we go travel into space with a "warp drive" that makes traveling much faster than light possible (not know if possible), we need to develop a way so we can see where we are going! How can we get information going much faster than light?
