So today in physics my teacher was talking about the bullet train that is in japan. SO this train is traveling at 190 miles an hour, and on this day there is no gravity and no air. a man walks to the back of the train and fires a bullet from the back. My teacher said that a person watching...
jesus! i haven't been on in a while and i was reading all your posts.. there great they do help but another question is if we don't touch anything then how come when we rude our feet on a carpet then touch the door knob it "shocks" us.. doesn't that require friction?
SOooo i finally understand (with in reason) M theory! but correct me if i am wrong, they say the universe (or multiverse) started because parallel universe collided and gave mass and such and formed our universe. But what i don't no is how can we tell the actually existence of parallel...
heres another question.. when we jump into water and we have water dripping off of you.. is the water actually touching you or do we have a "force field" around us in the water??

I don't know if this is in the right forum but i was wondering what is time? Does it have any relativity to the things happening in the universe and if not then what the point of it?(other then to get to the doctors on time)
Just because our Earth has water, why does that mean that life anywhere in the universe needs to have it? I no its most likely it will need it but how do we know? we are one plant of so many life could be out of carbon for all we know.
thx for the suggestion i have not read that but i would love to! but I am only a jr in high school i probably would get lost but if you have any others i would love to know. i love reading about this stuf
I have, for a couple of weeks, been looking up what string theory is all about but i can never actually really grip it. Is there anyone one out there who can give me a simple explanation of it?
i was watching this show on the science channel called the known universe it stated that we never really touch anything because our skin is made up of atoms which have electrons and since the things we touch have the same we never actually come in contact with anything? if that is true how do we...
