Light takes 3000 years to travel 3000 light-years, not 300k years
- drapred7 6y agoHe means relativistic speeds which is optimistically .01c making the trip take 300k years. He doesnt actually mean violating physical laws.
- ejolto 6y agoI don't think he does. He says "If we get technology to go at speed of light", "at speed of light" the speed of light is 1c. His previous sentence also makes no sense > To put some thing in perspective. If we get an instant teleport technology to go there tomorrow, it will be a planet that had passed 5 times more time then we know since our humanity almost went extinct 60k years ago. The light we see from the planet is 3000 years old not 5 times 60k. Space is big, but not as big as OP seems to think. The diameter of the Milky Way is only 150,000–180,000 light-years light years. All the exoplanets we have detected are within the Milky Way.
