How long is a day in a light-year? A “day” is a concept based on Earth’s rotation, so it doesn’t have a direct equivalent in a light-year.

How old is the light we see from the sun? The light we see from the Sun is about 8 minutes and 20 seconds old, since it takes that amount of time for light to travel from the Sun to Earth.

Are black holes faster than light? Black holes do not move through space in the same way that physical objects do. Their immense gravity warps spacetime around them, and their effects on nearby matter can be powerful, but they don’t move through space at speeds that can be compared to the speed of light.

Will we ever leave our galaxy? As of now, leaving our galaxy is beyond our technological capabilities. The vast distances and challenges of space travel make intergalactic travel extremely challenging.

Why do astronomers use parsecs instead of light-years? Astronomers often use parsecs because they provide a more convenient unit for measuring astronomical distances, especially for objects that are very distant. The use of parsecs is based on the concept of parallax, which provides a natural yardstick for interstellar distances.
