I thought I had finally achieved a peacefull status with him... Oh well, I guess some people are just to hard to try to communicate with....

when people slaughter the english language like that theres no point intrying to talk to them (yeah i know i have no room to talk)

You dont' slaughter the english language... well.. maybe.. not completely... just somewhat... Ok, you are found guilty of complete hypocracy... Your penalty is to writte a WHOLE sentence in correct and appropriate manner. With capital letters, and punctuations... and don't forget that spelling counts...

There may not be the ability to travel at light speed. But what about travelling along with light. If there was a body that could stretch with light it could effectively travel at light speed. Travelling through time is a strange theory because if all the actions we do are echoed into space as light then if we strech with that light we would be living in the past. If that was the case how does donnie see into the future if physics state that you cannot travel to an event that hasn't happened yet. There are many possibilities. Some are that donnie darko looks at several alternate universe if so what is the first universe. Maybe our actions spring off tangent universe's with alternate existences and timelines. Just a theory. Someone reply.

hey kool, another newbie... welcome
"There may not be the ability to travel at light speed. But what about travelling along with light." travelling along with the light implies you are travelling at light speed.
looking at it technically, a body that could strech at light speed, causes the same problems as a whole body moving at light speed would , as in you are still trying to accelerate some matter towards the speed of light... which gets increasingly harder as you get closer to light speed..
and yea your alternate universe theory seems the most likely..
"If that was the case how does donnie see into the future if physics state that you cannot travel to an event that hasn't happened yet." it is wierd the way he can see into the future alright, maybe because of his superhero powers or because the events have been played out in a similar alternate reality and donnie has the ability to see both realities. come up with your own theories and well discuss!

well the way i understand in is that there is no gravitanional pull in space (or at least not enough to make a differance) so if you hit a good thrustwhould get you moving at a god speed so you would continue at the speed (no gravity)so another burn should greatly increase the speed and by doing that u should be able to move at the speed of light simply by quick byrning the thrusters and cutting them off

There is gravitational pull everywhere - it reduces proportionately witht the square of the distance you are from the mass pulling you. At great distances this can become negligibly small but never zero. In special cercumstances, where different masses pulling on you from different directions 'cancel' each other, can result in a zero net gravitational effect - but in general this is unlikely. (Look up 'Lagrange Points' for some interesting reading on this point).
A good description of Newtons 1st law of motion.
This works in flat Newtonian space (where there is no limit on speed), but not in curved space. Explanations of why this is so have been covered in both physics threads

The E=mc2 theory that applies to nuclear physics might be able to be taken into account.
It might sound totally stupid but if it is just tell me.
The reason alpha radiation is less effective than gamma is because alpha moves faster. Alpha is less effected by the electronic force of the other electrons because it passes faster. If you could somehow travel fast enough couldnt you ignore gravity?? or at least get it down to an "X-factor" that could be discarded?

The equation e=mc2 is addressed earlier in this thread.
Gamma radiation is faster than alpha;
Gamma is essintailly pure energy, and moves at the speed of light.
Alpha radiation is particles formed of two protons and two neutrons (helium nuclei) and travels at well under c. It is less effective beacause the reletively large particles are unable to pentrate materials - alpha radiation can be blocked by paper or clothing quite easily, where as it takes several feet of concrete or a few inches of lead to stop gamma radiation.
If you were travelling fast enough then the gravitational effects of passing objects would be transitory and you could likely ignore them - unless you happen to be heading straight for, or very near to a very massive object - like a black hole for instance.

Thats quite strange its been two years since i was in physics my brain is most likely rusty. lol
I must have got them mixed up.
But anyway here is an explanation of the experiment, that he did.
*teacher fires rubber dart, hits no one.
says this is alpha radiation
it travels fast and does not have time enough to effect the surrounding particles.
*teacher puts on a boxing glove and walks around a room, hitting several pupils.
says that this is gamma.
it moves slower and has the ability to tear more electons from the nuclei. which is why it is more powerful.
Thats what i was told, can you explain it properly.
I feel confused.

Each Alpha particle will quite happily strip 2 free or weakly bound electrons from thier surroundings. Once it has done that it becomes a helium atom which is inert.
Since there are plenty of electrons available even in air, even a strong alpha source wont penetrate even air for more than a few feet.
Gamma on the other hand is quick and will deposit energy into whichever particles it encouters in it's path and will penetrate deeper.
The example from your teacher (above) works if you switch gamma and alpha and only consider a single 'particle' of radiation. But if you consider radiation sources (millions of particles) then it breaks down - an alpha source is easliy shielded and has little sustained affect, whilst gamma will penetrate deeply, doing a little damage to many particles - multiply that by a million and you are in trouble!

I bow.
Thanks for that, its been years since i was in a physics enviroment.
So what about the fact that if donnie chose death then the certain evernts leading upto might not have happened and the plane might not have lost an engine. what id donnie dies then the world is sent into a paradox where it loops the next 28 days over and voer again because time cannot find one way to exit. and the film was just one of these extracts in that time.

well theres another aspect of time travel we have to look at the human concsense in time what if traveling forward and backward in time did not put us in that time to relive it but the eft overs from that time the people arnt there just the inanimate objects that can not consiveably out run time in this aspect time trave would only be achivable in minutes not years fo if you go back far enough then it all deteriates and traveling forward we can't out run our time for ever so it would eentually catch up to us jut a litle brain bender i'm sure bigboy will outline my thoughts better than i have (he is goodat that )
