when you pull a rope taut it always makes a straight line between both ends. At some point when you are walking around the Earth the straight line would intersect the Earth's circumference.

Try this:
Take a bottle similar to pic. Cut off a few centimeters from the bottom, so that it is now a gaping hole. Take of the bottle's cap, then submerge half of the bottle (neck side up) onto a basin with water. Suck up some water as you would when using a straw, while lowering the bottle so the water level inside it is the same as outside. Now, replace the cap. Pull it out of the water, record and post your results.

the shit you learned in high school (V_total = V_a + V_b) is called galilean velocity addition and only works for velocities far below the speed of light, so the factor of (v/c)^2 does not come into play. learn some real physics by taking some GR course at university you dumbfuck.

We start with E=mc^2
Einstein's mass equivilance equation, right? This "all powerful" amazing thing that this man was mostly famous for correct? Just one problem: Einstein was wrong. According to modern physics, there is so little mass the in the universe compared to energy that we can just cross off mass and thus get E=c^2. So as you can clearly see, energy can be formed from the square of the speed of light. You can thank me later physicists.

even if you somehow manage, that still doesn't solve the problem of you dehydrating. so basically you need a constant supply of H2O for this to work, and H2O is like 90% oxygen, so you're basically running in a loop.

it doesn't work. one of the basic stipulations of einstein's theory of relativity is that the speed of light in vacuum is a constant in any frame of reference, which means, (quite conter-intuitively i must admit), that if you shoot a beam of light on a train traveling at the speed of light, the beam of light would be stationary relative to the train and not moving forward at 2C.

conservation of mass is irrelevant. the fact that the total oxygen and hydrogen content of the universe stays the same (which isn't even true in the first place since there's something called FUSION), doesn't stop YOUR BODY from dehydrating.

i.e., your body loses water, of course, something else would gain this amount of water, but as long as that something isn't your body, you will dehydrate.

the "instantaneous" motion of a solid steel bar you see in real life is not instantaneous at all, the moment you push one end you send a compressional wave moving at the speed of sound in steel towards the other end. for objects of ordinary lengths, the time delay is irrelevant, therefore the feeling of instantaneousness.

for objects of the order of light years, it would take forever for the movement at one end to transmit to the other end (speed of sound in steel is of the order of kilometers/sec)
