s this scientifically impossible?, it can “NEVER” hit the ground…can it?

It's a phiosophical concept which in reality we know to be flawed, it's the same as taking a picture of an arrow, in the picture the arrow is still, so what proof is there that it was ever moving? This is philosophicaly sound, but scientificaly absolute rubbish.

Moreover, it highlights the gaps between our observations, and our understanding thereof. We observe something to be happening, but can't reconcile or explain it logically.

Then you still have more left to eat? :p

But yes, as far as I understand it the train would slow down probably to the point where it would be such a small difference you wouldn't be able to measure it, however the fly would stop and then travel in the opposite direction.

Because the fly does not have near the mass to make a difference on the train.
 
Its not really a philisophical concept... theres a point at which the granularity of our universe is observable - at which point there no half distances your either in one position or your not so to speak.

What it highlights is that the human mind can think up a whole lot of very profound yes inevitably pointless twoddle.

So in a true continuum, Zeno's paradox would apply, and all motion would be impossible?

Yes. And finally We humans are Earth Inhabitants, but from the so called “big bang” theory, how did we finally reach this destiny? – here on Earth.? From A-Z (A=big bang) to (Z):Earth. However, what happened before the “big-Bang” ?, and are we really situated here on Earth, at “Z” (final destiny), or is it always ongoing? – as it is really isn’t it……..

It's the dichotomy paradox, the one I mentioned is the arrow paradox and as Inquisitor says, are part of a collection thourgt up be Zeno.

It's the same kind of paradox as "if everything has a place, everything itself must have a place" which goes on and on and on and on.

Reminds me of

An engineer, a mathematician, and a physicist are each presented with a beautiful woman 8 feet away and the stipulation that at each time interval, they may move half of the remaining distance towards her.

The mathematician concludes that after N iterations there will be 8 divided by 2N feet remaining which will never equal zero so he gives up on the spot.

The physicist opines that if each iteration requires a finite amount of energy then the energy expended in the approach will be inversely proportional to the distance remaining and gives up on the spot.

The engineer says "8 feet, 4 feet, 2 feet, 1 foot, 6 inches, good enough for practical purposes".

So Zeno was basically the Devil's advocate, being a pain and making up 'paradoxes' for the rest of that bunch of Greeks to get agitated over? I like him!
