If an alien in a galaxy 65 million light years away is looking at Earth through a telescope right now, then they are seeing… dinosaurs!

Sounds crazy, right? But let’s wrap our heads around this for a moment! Light from events that happened 65 million years ago is still traveling to us. This means that if an extraterrestrial civilization is advanced enough to observe us from such a colossal distance, the images they would be receiving are of Earth during the age of dinosaurs, which spanned roughly 250 to 66 million years ago.

Incredible, isn’t it? The period when dinosaurs roamed our planet (from their appearance about 250 to 235 million years ago until their extinction 66 million years ago at the end-Cretaceous extinction) falls perfectly within this “observation window.” Anyone observing us from a galaxy approximately 65 to 240 million light-years away is likely witnessing a completely different Earth, one where these magnificent creatures still thrived.

This is a stunning example of the vastness of the universe and the fascinating way time and space are intertwined. Just imagine, perhaps somewhere out there, a civilization is marveling at “historical” footage of our planet that we ourselves have never even seen!
