And if you remembered to wear your glasses or not. Also do we have binoculars.

More importantly is it daytime or night time.

And are you asking for a horizontal view or by "south" do you mean towards the South Pole. If that is the case, then about 70 inches.i will leave the trivial conversion to km to you.

I’ve instructed Fraü Farbissina to release a highly trained swallow, laden only with a gps tracker, so I can do the calculations on the second scenario from here and I will back up with figures from the appropriate mapping software. I usually use unladen swallows but they are only good for airspeed calculations.

The first scenario is simply a bit of trivial math.

I have given the answer for the third scenario.

Show your work. Marks will be taken off if you don't.


I would have to know the elevation of the lookout point. I think I have the equation using the 3 4 5 rule and taking in the account of the curvature of the Earth. I could come up with the answer in miles and would just have to convert it to kms.

Gazing in a southerly direction, the sky is within my field of vision. I would be gazing into a boundless universe.

My answer: infinity
nothing wrong with being open minded as long as your brains don't fall out.

"The Earth's surface curves out of sight at a distance of 3.1 miles, or 5 kilometers. But our visual acuity extends far beyond the horizon. If Earth were flat, or if you were standing atop a mountain surveying a larger-than-usual patch of the planet, you could perceive bright lights hundreds of miles distant. On a dark night, you could even see a candle flame flickering up to 30 mi. (48 km) away."

Nowadays it's almost rude to ask a question without Googling it first!

My answer: infinity


The maximum distance one can see from the earth is 46Billion light years, making your answer nonsensical, nobody can see infinity.

Assuming it's daytime and everything south of you is a cue-ball. Lake surface is the surface of the cue-ball.

We, like other sentient life forms, are here because it's the only way the universe can perceive itself.

Universe is 13Billion years old, that is the oldest light one can see, but the edge of the universe is 46B LYrs from Knox Mtn.

Okay. You said "see", not how much spacetime has expanded.
