Speaking of bad neighborhoods....College Ave. gets VERY rough in some areas on the outskirts of downtown indy...
Anyways, I have locked my doors when i've felt threatened or when i sensed danger...But i can be paranoid...I travel with 2 different knives in my car and I have a baseball bat in my room...
Now for my Hypothetical question...and maybe someone with a better grasp on physics can help explain this to me.
---The conservation of Mass theory tells us that matter simply "is" and cannot be synthesized or destroyed, it merely changes forms. SO...If we accelerated a particle to the speed of light or beyond it, if i understand correctly, it turns into energy, and that energy, must dissapate to somewhere, it cant just be a ball of random "energy" right? THEREFORE...if we can truly achieve light speed, could we not also break the conservation of mass theory, thereboy making light speed travel impossible, but also perhaps giving us a new solution to pollution, etc----
Discuss/Explain?

mmm I'm a chemistry major but I'll try to digress on this... mass will never be able to travel at the speed of light... this is clearly expressed in equations for special relativity.... pardon the following messy formula:
<GTEA RELATIVITY LECTURE>
this is for transformations of a length by the way (just one of the many derivations)
(L' / L) = sqrt(1 - (v/c)^2)
in this equation L' is the relative length, L is the length at rest v is velocity of the object and c is the speed of light.
ok now that we have that out of the way... we can see in the equation there are some major points to it on certain cases of v...
if v = c (velocity equals the speed of light (part of your question)) then you'll have sqrt(0)... this implies the length of the object is 0, hence doesn't exist...
if v > c then sqrt(v/c) > 1 and you'd be subtracting a number from one that is greater than one... then you get to the sqrt function and you'll be taking the square root of a negative number, thus giving you an imaginary number... this is not possible. hence according to Einstein travel back in time is not possible
if you want to look at it in another form you can view the equation for change in mass:
(m' / m) = 1 / ( sqrt( 1 - (v/c)^2) )
this shows that if v = c then you'll have (m'/m) = 1/0 and you cannot divide by zero (I hope you know this otherwise forget everything that was said in this post, it may hurt you).
</GTEA RELATIVITY LECTURE>
so according to Einstein’s theory of special relativity nothing containing mass can travel faster than the speed of light. And balls of random energy can be produced although generally it wouldn't "glob" together. But then again all mass is just energy but I don't feel like going into that right now
sorry for second long post!
EDIT: I indirectly answered the question though. to be more direct: objects with mass cannot exist after the speed of light. You cannot get these objects faster than the speed of light according to the theory... there are many theories which I could divulge into, but I'll spare the board. if you are interested PM me and I can explain more. There is one concept which is almost certain to be faster than the speed of light and that is the speed of gravity... the speed of gravity is believed to be infinite (I'm talking about speed, not acceleration so I don't want any flaming posts about 9.81 m/s^2 or 33.whateverbecausetheenglishsystemsucks ft/s^2) ugh I gotta stop going off on tangents

*flames Green Tea* Just because you're my friend and I like you.

Wow....
I hope I'm not the only one here that's confused...
Looks like that question was taken care of, then. Next?

Time for my question, it's mostly for straight males though.
If my sperm had magical properties that could grant you mutant powers, what powers would it have to grant in order for you to suck my cock?

The power to turn pennies into (relativly large) piles of cash.
Yep, that's right... I'd do it.

What in the world made you think I wasn't in the first place?

"WWEJD?" there you should know what it is....
What Wuold Emo-Jesus Do?

Do you think Jesus had a big cock? I mean he was the son of God why wouldn't he? But then you never read about him having sex(why would you) it's possible he didn't have one or it was very small. Or prehaps it was very small but he just used his super-jesus powers to make it huge, like he did with the fishes.

but would emo-jesus have one? he's not quite as powerful. he suffers from bloodloss, and depression.

Well does emo-Jesus cut his penis when he has an erection because of high bloodflow?
No cuz emo-Jesus isnt that smart!

There is one interesting theory that could result in FTL speeds. There is only one elusive peice of the puzzle. We have to prove that mass is not stagnent or monotonic. In other words, we have to prove that Negative mass exists. The only problem is, is negative mass objects cant exist at speeds UNDER the speed of light. However i will say that relativity and newtonian gravity are not all encompasing, and may not even be correct (however they are probably a close example).
