[00:00:00]Did you know that every time you look into space you're looking into the past?

[00:00:05]You don't need a time machine to see the past >> [music] >> because light takes time to travel through space.

[00:00:11]When you look at the moon you see it 1.3 seconds in the [music] past.

[00:00:16]The sun 8 minutes in the past and the Andromeda [music] galaxy you see it over 2 million years ago.

[00:00:24]That's because light [music] even at the fastest speed possible still needs time to cross the universe and our observable universe is about 93 billion light [music] years wide meaning the farther we look the further back in time we see.

[00:00:39]Telescopes don't just look through space they look through time.
