Theoretically if I was 66 million light years away from earth and had a telescope strong enough would I be able to see the dinosaurs if I faced it towards earth and nothing was obstructing my view?

Question

Theoretically if I was 66 million light years away from earth and had a telescope strong enough would I be able to see the dinosaurs if I faced it towards earth and nothing was obstructing my view?

In: Physics

Answer 1

* 67 light years: 6×10^(17) m
* minimum resolution to see a dinosaur: 1 m
* wavelength of visible light: 5×10^(−7) m

Multiplying and dividing gives a minimum telescope diameter of 300 million km.
