Lets try this...

Did a problem in first year applied maths. Turns out a perfect vacuum can only suck water up from 11 metres below (if memory serves, and plenty of forces were neglected, it was 1st year after all!). Forgot which theory was used. No idea how they get oil out from deep down in the ocean tho although the immense pressure down there can be a contributing factor

EDIT: found something for you. Shame for your pipe idea

So Light should not be used as a measurement of time? if someone had the supernatural ability to move faster than the speed of light, then would this not allow his ability to create the effect of being able to stop time? Meaning that if you were standing across the room from me, and were about to pick up a book, and hyperthetically if i had this ability, i could move at that speed tho pick up the book before you and return to my original spot. to me it will seem as though i have stopped time, while to you it will seem like a de'ja'vu moment?

BTW headlights might be useless if we ever do get to go faster than the speed of light, LOL

Well put. Changes my view of things a bit

Some deep thinking was involved I have always wondered about time travel... Can't see it happening tho - unless you can somehow dematerialize yourself into energy particles and shift into a different / alternative dimension of space and time. But I think the ramifications of that would actually change the future completely, just like the butterfly effect.

Something else I had thought of was if you could travel at the speed of light, what do objects look like when you are moving away from them (stationary?) and if you are moving towards the objects, does it look like they are going faster? Personally I think that traveling at such speeds is probably not going to ever happen. The friction alone on whatever vessel your are traveling in would be astronomical ... I think you would burn out like a comet does (which does not even come close to the speed of light)... Again I think the only way to ever really move fast like that is not to move at all but phase shift through various dimensions.

You just moved faster than the person trying to pick up the book. thats all....

True, I agree with that, but to my eyes and his eyes, would it not seem like time stopping, and dejavu for him? because one moment he will see the book in front of him, and the next split second he will see me with the book in hand? I know normal cameras would never be able to pick it up, because their frame rate is 25 for every second

Not de'jevu, just odd, the book would be there and then it would be in your hands. By the way, at what speed does your brain process images? can you move faster than that, or will it be beyond humans physical capabilities?

Some interesting thoughts on light speed and vision:
the speed of light = 299 792 458 m / s, to process an image via the human eye = 50ms or 1/6 of the time it takes to blink.

1) The distance between your retina (inside your eye) and the back of your head (where the sight-specialized neurons reside) is far shorter than the distance between the sun and your retina.

2) Your eyes send out small electric impulses (not light!) from the retina to the brain.

Therefore, there are distinct phenomena here: the propagation of light; the conversion of light into small electric impulses; and the propagation of these impulses. But notice that "sight" is a complex phenomenon. The cells of our retina have to pick up the light and transform it into an electric impulse, and this impulse propagates in the nerves.

The "sight" you mention is as fast as your other senses, because it uses the same medium: nerves. You can measure you fast the tiny electric signals propagate in the nerves by using something called "evoked potential" techniques, similar to electroencephalograms (EEGs). With it, you can time the passage of a nervous impulse from your arm to the base of your brain, for example. This takes a few thousandths of a second, which makes it around 300km per hour or around 200 miles per hour. This is far lower than the speed of light in vacuum by a factor of around 1 million.

It takes about one nanosecond for light to go over the equivalent distance from your eyes to the back of your head. However, the nerve impulses are about 1 million times slower.

1. Will the vacuum of space not be powerful enough to suck things up into space?

No. the vacuum of space doesnt suck anything, its the atmospheric pressure on earth which will 'pump' the oil; see calc below

Did a problem in first year applied maths. Turns out a perfect vacuum can only suck water up from 11 metres below (if memory serves, and plenty of forces were neglected, it was 1st year after all!). Forgot which theory was used. No idea how they get oil out from deep down in the ocean tho although the immense pressure down there can be a contributing factor

Correct. But I had to pull out my applied maths calculator to prove it to myself.

Given that P = rho*g*h

where rho= density of water (1000kg/m3) or crude oil (800-950kg/m3)
g = gravity (9.8m/s2)
h = pressure head (height)
P = Pressure (Pa)

Now assuming:

------------------------- space? (Pressure = 0 atm= 0kPa)
| |
| |
| | pipe (height, h = ?)
| |
| |
------------------------ sea level (Pressure = 1 atm = 101kPa)

Then h = P/(rho*g) = 101kPa/(950kg/m3 * 9.8m/s2) = 10.8m only

So yes is if the edge of space was at about the height of a double storey building you might be able to suck the oil into space

but because the edge of space (where you start floating) is at a height of about 400km; you would really need the Pressure of earth to be around (P = 950*9.8*400km) = 3,724,000kPa or 37,240 atm; i.e. atmospheric pressure needs to be about 37,000 times stronger remember its the pressure on earth which 'pumps' the oil up - not the vacuum of space that sucks stuff

Earth would then look really interesting

1. No, the differential pressure difference acting on our atmosphere of space is balanced by the gravitational forces from our planet. Our atmosphere stays where it is because of gravity. Putting a pipe anywhere won't change anything.

2. No, well, unless the exhaust gasses from the rockets leave the system (the planet and its atmosphere) which they won't. You will need an external force to affect the rotation of the planet, an internal force will not work as it will always be balanced. Newtons third law of motion.

2.b. However, if we had a sufficiently large flywheel on our planet, we can affect the rotation by rotation our flywheel. Because its an internal system, angular momentum is conserved, by starting up our flywheel the rotation of our planet will be affected, depending on the direction we choose to rotate our flywheel. For a simple demonstration on how angular momentum works, if you have a rotating office type chair, spin yourself as fast as you dare with your legs tucked it, and then when you are comfortable that you have reached a quasi steady state, stick your legs out and you should notice the rotation velocity that you are experiencing will diminish. This is because you are increasing the rotation inertia of your body and the velocity decreases in order to keep rotation momentum constant. Obviously drag and other inconveniences muck things about somewhat, but try it and you will see that it is so.

No I don't think light has anything to do with time. To my knowledge it's just an amazing little thing called a photon that we through evolution have developed the ability to use, it seems every sensory organ for every creature is created/developed based on the environment so evolution somehow has a smart way to adapt to these things - how? I have no freakin idea e.g. if there are vibrations in the air, life will create ears to pick it up. If there are electric currents in the ocean, life will once again develop a means to use it - I'm thinking lateral lines and hammerhead sharks etc...

So, anyway, if we travel towards something and we are going faster than the speed of light relative to that thing I think we would still observe it. Our sight would process the image at 5ms or whatever it is just the same. However I think the faster we travel towards something - it may increase the intensity of it's light because we will pick up so many more photons in the same timeframe. Perhaps up to a point where it will be blinding?

When it comes to different dimensions :/ I don't understand this concept at all. I still can't even phathom 2D nevermind 4D. haha On a computer screen 2D/3D is just a trick with light. Nothing I can think of is truly 2D. I gotta read up on this stuff one day and yes I did Science and math in school - dunno how I passed

But anyway now I am off topic again soz OP
