what if?

..the sun disappears? We won't notice it for 8 minutes, unless gravitational waves are momentarily, but I doubt that.
..the moon disappears? still it will take more than a second to realize that..

..I disappear? I doubt it even will be noticeable. I miss that feeling of someone waiting for me to get back from wherever I am to wherever I am being waited for.I miss the feeling of being missed, that someone cares.. in this case I am either so far far away that information will take ages to arrive to the destination. or I am just an insignificant star of median size and brightness lost somewhere in the void of space..I want to go supernovae, or, in my case, at least to become red giant to get to the point of transforming to be a white dwarf..
