Question: how long would it take to get to the end of our galaxy?
Answer: How long does it take to get to the end of the universe? It's Space Day, but traveling the vast entity that is space would take far longer than a single day. The nearest galaxy: 749,000,000 (that's 749 million) years. The end of the known universe: 225,000,000,000,000 years (that's 225 trillion) years.
