Why is space black if the sun is there?

The blue color of the sky is a result of this scattering process. At night, when that part of Earth is facing away from the Sun, space looks black because there is no nearby bright source of light, like the Sun, to be scattered.

What is beyond the universe?

Would your blood boil in space?

In space, there is no pressure. So the boiling point could easily drop to your body temperature. That means your saliva would boil off your tongue and the liquids in your blood would start to boil. All that bubbly boiling blood could block blood flow to vital organs.

Would you freeze instantly in space?

This would not happen. Though space is typically very cold — most floating objects have a surface temperature of -454.8 degrees Fahrenheit — a person would not instantly freeze because heat does not transfer away from the body very quickly.

Thus, upon calculation we find that one hour on Earth is equivalent to seven years in space. Einstein’s theory of Special Relativity stands as a explanation to this calculation.

How cold is space?

Space is very, very cold. The baseline temperature of outer space is 2.7 kelvins (opens in new tab) — minus 454.81 degrees Fahrenheit, or minus 270.45 degrees Celsius — meaning it is barely above absolute zero, the point at which molecular motion stops. But this temperature is not constant throughout the solar system.
