Long journey

How long would it take to travel from one end of the visible Universe to the other end, if you were travelling at the different speeds ???

Ans:

  

$$1. speed = 1 Ly/sec$$

$$\text{Distance from one edge to the other}= 93*10^9Ly$$

$$Time = \frac{distance}{speed}$$

$$Time = \frac{93*10^9}{1} = 93*10^9seconds = 1.55*10^9min = 25.83*10^6hours$$  

$$=1.076*10^6days = 2948.63years$$  

Now:

$$2.speed = 1parcsec/sec$$

$$\text{distance from one edge to other}= 28*10^9parcsec$$

$$Time = \frac{28*10^9}{1} = 28*10^9sec = 4.66*10^8min = 7.77*10^6hours = 3.2*10^5days$$

$$= 876.712years$$
