Thread: The Most Accurate Theory for Looking into the Past

Wrap your head around this. Say we as humans manage to get a telescope 200 million light years away from earth. If we looked back and pointed the telescope towards earth today, what would be the outcome? Is it possible we could see back in time to when the dinosaurs existed? Please give me your thoughts.

Not possible. It would take us more than 200 million years to get the telescope in place. We cannot ever catch up with the light that left the planet in the age of the dinosaurs. (And we haven't even considered things like resolving power, etc)

Ordinarily no, but one slight possibility might the Acubieere Drive, which would be capable of travelling at more than C.

Apart from this though, is that I don't think any telescope of any advanced design would be able to resolve clear pictures of the earth's surface from that far away, since there would simply not be enough photons around for it, afaik.
