if time travel is real, should it be made illegal, penalty death!!?

some believe christ was perhaps a time traveller. there have
been shows on fugitive outlaws travelling through time pursued
by fugitive divisions of the future. according to some theorists
when the time barrier is broken, about ten trillion cubic parsecs
of space explode into the 'substance' that was here before space
was here. what do you make of that? is total mass created then?

is this correct????

suppose you have a coin collection of dimes and quarters containing 46 coins. if you have $6.70 how many of each type do you have:
quarters=25cents dimes=10cents
25*24=600 10*7=70

600+70=670 ??

derivates and related rates?

Cars A and B leave a town at the same time. Car A heads due south at a rate of 80km/hr and car B heads due west at a rate of 60 km/hr. how fast is the distance between the cars increasing after 3 hours

I have completed the problem, the answer I get is 84.515
but I don't know if it is right....
my question is this, when do you substitue given numbers in this case, before or after you take the first derivative?

As part of an assignment we have been asked to find at least two functions for Ribosome's.i can only find one function and that being protein synthesis.
Is there any other functions of Ribosome's apart from protein synthesis?
please help!

Why would this not result in something going faster than light?

I build an ion-powered spacecraft. It has an Ion engine on the back, which accelerates Xenon ions electromagnetically and shunts them out the back, eventually allowing my little craft to pick up to a significant fraction of light speed after a few hundred years.
I also have a particle accelerator on my ship. It is pointing forwards. I wait until we are nearer to light speed, say 80%. I then accelerate an antiproton or a Higgs Boson or similar makeyuppyon to 30% of light speed, which I believe is possible in a linear accelerator, and fire it forwards. Why won't it be doing 110% of light speed?
I am sure my little plan is full of complex holes but am keen to know what they are (financial considerations not included).
