Definitions of past, present, and future get confusing when you venture deep into the cosmos:
Space is so vast that every location exist at a different "now" from our point of view. Light from objects at left takes minutes to reach us; for objects at right, light takes years to arrive.
. What you are seeing now happened 13.8 billion years ago, but it is also an integral part of the universe now...wheneverAt some point in the future, Betelgeuse will blaze as a brilliant supernova. At some point farther in the future, it will have completely faded from view. Or maybe these events are already in the past from some perspectives.
Light from the Sun takes a little over 8 minutes to reach the Earth, so you see the Sun as it was 8 minutes in the past. Is it sunny outside right now? Well, the scene might be sunny, but the sunlight is 8 minutes old. Are you really sure the Sun is still there? Light from the Moon takes 1 1/3 seconds to reach the Earth, so you are always seeing it as it was a little over one second ago.
