well i have no idea, kind of speechless, how ignorant can you get?...it would be impossible since we are nothing in mass compared to everything else in the universe, and we are ON the earth. we would need incredible force to even budge the planet! what was this professor thinking?
Don't underestimate the action of the human stupidity, please... 
Some people are so mundane...
that they hurt themselves and others!!!...
^Does this sound like new information, or does it sound surprising?
Not at all... "thrills" are often actualy "sin",
which is error or shortcomeing [which is un-healthy for they and others],
because of excessive desire or lack of understanding...
Which means we must calm and educate ourselves in life.
^
Id be happey if even 1 person who read that felt better or smarter.
Have a great day my freinds!
(edit:)
Wait, that has nothing to do with jumping from high altitude...
Still, quite retarded... and a waste of time...
like so many other things are... and slightly amusing?
