There are 500 billion other galaxies (that we know about). One of the closest galaxies to us is the galaxy Andromeda at 2 million 200 thousand light years away. The light we see today from Andromeda, left Andromeda 2.2 million years ago and traveled through space in that amount of time to reach our telescopes.
A person standing on a planet in Andromeda, looking back to earth today would not be able to see human beings!

2.2 million years ago there were no humans on planet earth!

The farthest galaxies we see today are over 13 billion light years away. The light we are seeing from these far away galaxies is 13 billion years old. It is a picture of how these galaxies and the Universe looked 13 billion years ago which takes us back in time.

These farthest galaxies are moving away from us at tremendous speeds, some close to the speed of light. Where we see these galaxies through our telescopes today, are no where near where these galaxies really are today. Because 13 billion years ago they were traveling away from us close to the speed of light, today those galaxies are close to 26 billion light years away from us. The problem with seeing them is we won’t see that light for another 26 billion years, the time it takes that light to travel through space to reach us. Oh what a wonderful Universe it really is.

Light travels 186,000 miles per second. That is 3/4’s the distance from the Earth to the Moon or 7 1/2 times around the Earth, in one second. In one minute light travels 11,160,000 (11 million 160 thousand miles). In an hour light travels 669,600,000 (669 million 600 thousand miles). In a day, a beam of light travels about 13 billion miles. In a year light travels close to 6,000,000,000,000 (6 trillion) miles. A light year is a measure of distance.

Imagine some other civilization in some other galaxy, using a telescope to look at Earth.

They are, for example, 5 billion light years away (and imagine that distance between us and them is constant, what is impossible).

Question: What would they see through telescope, if looking today at the solar system?

Answer: They would not see the planet EARTH, cause our planet most likely didn't exist 5 billion years ago.


Try a billion light years closer.

How about intelligence on a planet 4 billion light years away?

They would see Earth, but no life! The first life on Earth may have appeared 3.5 billions years ago.

How about they try to see The Great Wall of China?
They would have to be less then 2000 light years away. How many stars are so close to Earth?


The same is the picture that we can see. All wee can see is distant past, thousands, millions or billions years past.

If it has taken 20 billions of years (since big bang) to develop computer and satellites on planet Earth, how long time could it take on other planets?

Think again!

There was no space before time and there was no time before space. When the Big Bang happened, it was not an explosion as say dynamite or a firecracker. It was an explosion of space and with the beginning of space the beginning of time. It was the beginning of our the Universe. We don’t know if there are other Universes that have come and gone or if this is the first and only Universe there ever was and ever will be. We don’t know if there are many different Universes beginning at different times or if there were many separate Universes that were made at the same time as our Universe. We don’t know if our Universe will eventually recollapse in on itself and form another Big Bang making another new Universe. Maybe our Universe has re-expanded and re-collapsed many times, making new and different Universes each time. There could be mirror Universes of our Universe or there could be opposite Universes of our Universe. There could be other Universes with completely different space, time and physics that are so different that we could never recognize them with different physics than the physics of this Universe.
