# Weird universe

Classical Mechanics Level 5

Suppose that we live in some crazy open universe, also the concentration of stars is constant and equal to $$n=10^9 \frac{1}{Mpc^3}$$ and the mean radius of the star is $$R=\frac1{\sqrt \pi} 10^8 \text{ km}$$. Find the average distance 'view' will travel before it 'hits' the star. Answer in $$Mpc$$

Example: if you look at tree 9m away from your eyes your look will travel distance of 9m.

$$*1Mpc=10^6\times 206265 \times 1.5\times 10^8 \text{ km}$$
