Thats what I’ve been trying to tell everybody.
If you’re talking to someone about this in person, just doing the math for them is usually wonderfully convincing, because the average person assumes that any math related to astrophysics is way beyond their grasp and any person who can memorize such math is insanely intelligent... and they just say something like ‘Oh, OK... I guess you’re right then, I have no clue about this kind of stuff’ and be completely in awe of you.
*Note to self: This does not work as a pick-up technique, and I should not attempt to use it as such again...
