Yes. Why do people assume you can just make a phone call to Andromeda? 'Ya, hi ET, what's new?' If Andromeda disappeared into a black hole 1 million years ago, we wouldn't even know yet. We have to wait 2.5 million years for news from Andromeda, assuming the news can't transcend the speed of light. |
