Why can't a human fly?

Because you fit the terrorist profile too closely.

Hai All,

Is this possible to fly on the sky?.

it possible is it

we don't have wings

That's a very interesting question... I'm posting this onto yahoo answers and see what they'll say, I'll message you guys back when I get some replys.

And then, naturally it will be followed with another: "Why can't a man be an elephant", or "Why can't man breath under water" - and the ultimate - "Why should humans die?".

Well, maybe they should, maybe they shouldn't, but that's the way it is, and that's it !

By the way: "Why can't we travel in space faster than light ?" and "Why can't we go back in time?" - are basically the same question

You could just splice the DNA in your chest muscles to increase their power, the your arms and finally create something with a large enough surface area to give the air beneath you something to push up. But considering a human splice has only a 1:2,000,000 chance of success and the price of creating a possibly successful splice, this is quite unlikely.

You cannot splice mutant DNA into a mature body's genome, and simply expect a given increase of power or efficiency - this is simply a misconception of how mutant strands work.

If on the other hand, you mutate the desired genome of a newly-created zygote, before the phase of stem-cell speciation, you may expect a real change in traits - provided you pre-design correctly the role of your intended main and control-genes into the right biochemical nurturing enzymatic growth environment...

You get the picture - we're about a few centuries ahead of ourselves - knowledge wise...
