In the vacuum of space, a flashlight beam can theoretically travel indefinitely without obstruction, as there is no atmosphere to scatter the light. However, the visibility of that light diminishes with distance due to the inverse square law, which states that light intensity decreases proportionally to the square of the distance from the source. In practical terms, a flashlight could be seen from several miles away, but under ideal conditions and with sensitive equipment, it could potentially be detected from much greater distances, depending on factors like the brightness of the flashlight and the observer's sensitivity to light.

Why is space so dark when the sun is so bright?
Simply put, it is because space is very big and mostly empty. The vast majority of the light from the sun continues out into open space and never hits anything, very little gets reflected back for an observer to see. Most the universe is so far away that the sun, even as bright as it is, cannot be seen, just as you could not see someone shining a flashlight on the moon. The stars you see at night are suns much like our own. Some are even bigger and brighter but are so far away that they appear as dim little dots.
