created the universe in six 24-hour days. Muslims use science to back up their beliefs. The Qur’an mentions a period of six days‚ but these are not necessarily 24-hour days. With Einstein’s theory of relativity‚ it is discussed how travelling at near the speed of light and how gravity can slow down time.

It was completed in 1971 and stands 193 feet in the air. It takes 268 steps to climb to the top.

Light houses from the 18th century used burning candles‚ oil lamps

frame lenses have a bigger image circle than the image circle on crop lenses. This is the key difference between these two lens types and we have seen this in the many examples of cropped vs full frame. As I said earlier‚ full frame lenses have no problem adjusting to cropped sensors because the image circle is big anyway. On the other hand‚ if you were to put a cropped lens on a full frame sensor the image circle would be too small to cover the entire sensor and‚ as a result‚ you would get blackened
