I’m not sure if I worded my question correctly, but let me try to explain more.
If we use a giant telescope to look at another planet 10 light years away from us, we would be looking at how it was 10 years ago. The thing I don’t understand is how does light store and also transfer all the information about that planet (or all the “data” that ends up in our eyes) and yet it’s still the fastest thing.
In: 94
Two things :
– Light isn’t carrying the “data” as a payload in it. We interpret whatever we receive.
– strictly speaking, what we see is not how it started out as, so there is loss involved. If that was not the case then distant stars wouldn’t appear dimmer than closer ones.
