Why the whole of the earth does not experience daylight at the same time?

Rotation of the Earth causes night and day to alternate. Since we learned that the Earth’s axis is tilted and hence the equator is not facing the Sun directly, different places on Earth would experience unequal length of days and nights—not exactly 12 hours of day and 12 hours of night all the time.

Why is there no light in space?

In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.

Why does only half of the Earth face the sun at a time explain?

Answer. -Only one half of the EARTH gets light because as earth is round in shape so only one half is faced towards the light and the other half i.e.backward portion does not face toward light at that time so ,that portion does not bogey light and there is dark or night time at that side..
