Do Distant Celestial Objects Still Exist as We See Them?

[Edeff]

The light by which we see distant deep space objects left those objects thousands, millions, even billions of years ago, yet we speak of them in the present tense, Perhaps this is just a convenience; they may be more accurately referred to in the past tense. In any event, given that the light forming the images we see actually left the objects so long ago, how do we know those objects still exist?

I suggest you to post your question under Astronomy section of the forum, in this thread you are supposed to introduce yourself.

Short answer to your question, it depends on the object you are referring.
