Hi guys,
I am giving a schools talk and would like your opinion on whether or not you think the following reasoning is accurate and roughly scientific.
Lets we assume that on average there is only one hydrogen atom per cubic metre on average in the universe. The diameter of a hydrogen atom is 1.7e-15m.
Scaling up to the size of a human, can I say that the distance between hydrogen atoms in the universe is equivalent to:
0.3 (diameter of a small human) / 1.7e-15 = 1.76e14 m = 1100 AU
So the distance between hydrogen atoms in the universe is roughly equivalent to one of the kids standing the classroom and another kid standing 1000 times further away than we are to the sun (or if you can think of a better landmark to use I'd appreciate it! Mine is quite clumsy)
Does that logic hold, or is it outright wrong?
Thanks,
Leo
