So, how many scientists came to the conclusion that Contador's climb up the Verbier was impossible without artificial aid? How many scientists repeated their experiments or studies and found the same thing? Who verified their boundary conditions for their study (or studies)? Who verified that any assumptions made were valid? Was the study published in a refereed journal? What would scientists in 1903 have said about the possibility of someone riding an hour as fast as Chris Boardman did when he set a record in 1996? Show that it is the conclusion of the majority of exercise physiologists and other scientists in significantly related fields that such performance are impossible without artificial aid, and then show the data that all of those people agree on.
Your supposition and accusation that obviously doping is the reason behind these performances lacks factual basis. Moreover, it fails critical thought to assume that since some riders dope, all performances that you don't understand or can't comprehend are the result of riders who dope. Sorry, I don't buy into rumor mongering or wild speculation. Frankly, it's stupid and lazy....and it's all too common.
Also, for reference, there is a sub-forum here for doping discussion and cavorting in rumor mongering. Simply scan down the page of sub-forums and you'll find it.
On to other topics......did anyone read about those engineers that said the collapse of the WTC on 9/11 had to be an inside job? Engineers said and studied so it's fact! Hey, some people in science and engineering said we didn't actually go to the Moon, land, and walk around! So it's fact that we didn't. How liberating.
And obviously the cow jumped over the moon because the grain he ate was pumped full of steroids and other performance enhancing substances.
