Time Travel

how do you know we cant do x and how do you know that the laws of physics are equal throughout the (our) universe, bottom line to the question is no one knows and that's simply down to humans not having the intelligence to create such a machine to enable this

Because physics is an evidence based pursuit, and the laws of the Universe are equal everywhere because local laws makes absolutely no sense at all

The bottom line is just because you don't know something doesn't mean that nobody knows something.
 
Physics bamboozles, i will get to thinking about time travel after i work out why, if the world spins at about 1000 mph, why when i stand still my face isn't covered in Gnats.

We're almost in December you daft ****. No Gnats around at this time of year.
 
its certain i don't know everything and have never declared so, but i'm pleased for you however you MAY be wrong

This again is somebody misinterpreting what that actually says. One thing researchers always do is make their discoveries sound Earth shattering because it alerts the mainstream press which gives them exposure which is what all scientific institutes crave; the paper itself is somewhat less ground breaking.

I'll grab a comment from elsewhere which may explain this better as electromagnetism is essentially still magic to me:

In physics, a coupling constant, usually denoted g, is a number that determines the strength of the force exerted in an interaction. Usually, the Lagrangian or the Hamiltonian of a system describing an interaction can be separated into a kinetic part and an interaction part. The coupling constant determines the strength of the interaction part with respect to the kinetic part, or between two sectors of the interaction part.

It is called constant because of historical reasons. It is a number that enters in the expansion to a mathematical series of a calculation of cross sections using Feynman diagrams, when we assume the interaction to be small to allow for a converging series expansion. It was neat that in electromagnetic diagrams it was a real constant, alpha.

There is no reason though to expect that the nice expression for alpha is also the exact expression needed in the final form of the Feynman series expansion of the cross section.

It was realized that the coefficients of the series had a calculable energy dependence. Look for the format in the link, page 9.

Thus alpha is not changed. The running is on the coefficient of expansion, quite legitimate, versus the energy for which the expansion is made. Physicists who have taken a course on this have no problem with the definition.
 
I stand corrected and bow to your superior Gnat knowledge....though gnats would have to fly 100mph just to stay still :)

It is a mystery though mate. If the Earth is indeed spinning so fast, why when I jump over our little garden fence don't I land in the miserable cunts garden at the end of the street?

The question that bends a few minds is if you get on a plane that's flying against the Earth's rotation why don't you travel the speed of rotation (~1000mph) + flight speed.

Is it god helping us? and as soon as we get far enough away from earth he thinks 'fuck it, if they don't wanna be here I'm not helping them any more'
