Why you might not be seeing stars in real time. The first discussions about the speed of light began with the ancient Greek philosopher Aristotle who considered light travel instantaneously. However, due to the curvature of space-time, light can also be bent and warped by large objects such as stars and black holes, so photons of light can travel faster than the speed of light. The farthest weve ever sent humans is about 240,000 miles away (the moon), and the farthest weve A light year is the distance that light travels in vacuum in one year, about 6 trillion miles or 10 trillion kilometers.

To give you a great example of how far a light year actually is, it will take Voyager 1 (NASAs longest-lived spacecraft) over 17,000 years to reach 1 light year in distance traveling at a speed of 61,000 kph. However, the Sun will never turn into a black hole, because it is said to have less mass than needed to turn into one. The exact distance at which the earths curvature becomes visibly apparent depends on a few factors, such as the height of the observer and the weather conditions. Because its future trajectory will depend in part on its current speed, the activity of its thrusters, and the influence of other large bodies in space.
