Then why is this question hurting my brain?
When we look at very distant stars, are we looking back in time?
Since we are using light year to measure the distance b/n objects in space, when we look at stars, the light that is hitting us now must have started from the stars long time a go that means the stars appears how they looked like some time ago when the light was emitted from it, right?
Ok in other example, Alpha Century, the closes star to earth is 3 light years away right? Does that mean the light we see from it now, left the star 3 years a go? So if the star was destroyed or gone from it is position, with in this time, we wouldn’t know right?
Am I making things complicated? Or do you get my point?
