Lots of people were dead so they wasn’t anyone to farm or work
The variable you would need to keep track of is hight
Mesosphere is the layer after stratosphere, which is after troposphere, as seen from Earth in the direction of Space.
It starts at 60 km and ends at 120 km, after which comes the termosphere.
So we're looking for a line that's closest to 100 km, and this is the shortest line, A.
The nearest star to our solar system is Proxima Centauri and if we traveled at the speed of light we would get there after<u> 4.25 years. </u>
<h3>How long would it take to reach Proxima Centauri?</h3>
Proxima Centauri is the nearest star to our solar system and it is located around 40,208,000,000,000 km away.
If we were to travel to it at the speed of light, we would get there in:
= Distance to Proxima Centauri / Light travelling distance per year
= 40,208,000,000,000 / 9,460,730,474,334 km/ year
= 4.25 years
