The distance of a galaxy is of the order of `10^(25)`m. Calculate the order of magnitude of time taken by light to reach us from the galaxy.

Explanation

To calculate the order of magnitude of the time taken by light to reach us from a galaxy that is \(10^{25}\) meters away, we can follow these steps:

### Step 1: Identify the given values
- Distance to the galaxy, \(d = 10^{25}\) meters
- Speed of light, \(c = 3 \times 10^{8}\) meters/second

### Step 2: Use the formula for time
The time taken by light to travel a distance can be calculated using the formula:
