Lets try this...

[trinityEon]

1. Take a long pipe into space, then lower it down towards earth near the gulf of Mexico, will it be able to suck all the oil up into space? What do you think will happen?

2. If all the countries in the world strap all the rockets they have to the earth, with the exhausts pointing east, Will this spin the earth the other way around?
If so how many rockets would be needed?
Will this make time also go backwards?

The theories on this will be quite interesting

 

[davemc]

1. The pipe will stand there and bend a little bit due to the forces imposed on it, but it will not suck anything anywhere.

2. Yes. How many, well, the question is, how much thrust will be needed, and to calculate that, you have to take the mass of the earth, and it's current spinning velicity, and the point that you're going to attach the rockets to and do the math. Will it make time go backwards? No.

a friend of my sister's actually believed that flying against the rotation of the earth would prolong her life if she did it indefinitely.
if she did it at the speed of light, i could understand, but i think she was referring to a regular long-haul carrier.
shame.

she is technically right though - you could live 1 day longer (flying from say the 24th SA time into the 25th AUS time just before you die)

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

2. If it will not make time go backwards and our clocks still go forwards, then what will happen to time while the sun rises in the west and sets in the east? how do we count time then?

 

[graviti]

1. Gravity kinda keeps things where they are.Just because I put a big pipe up there doesn't really mean the air pressure in the pipe is any different. If the pipe was infinitely strong so that it did not buckle under air pressure, maybe. But even then. Imagine the distance, say 500km of pipe, filled with oil. The pressure required to suck that up would more likely break the pipe, than pull up that much oil. A more accurate version of your question would be if I made a pipe that contained a vacuum, would that handle the job. Even then, I think the pressure required to pull up that much oil against gravity is too much, even for space. If it could then, how can our atmosphere handle the pressure of space's vacuum.

2. I don't know so much about question 2. You've got to ask yourself what forces are causing the earth to spin in the first place. You would need to cancel these out. Then you still need to generate a force big enough to stop the momentum of the earth, and reverse it's path. Rocket thrust would have to be immense, and we just don't have that capacity. Mathematically, it's possible, assuming you have all the resource available. Time going backwards is not gonna happen. Our concepts of days and weeks and months and years would change, but time would still move forward

1. Yes i was thinking a solid pipe that will not buckle under pressure, will it not be similar to the scenario of an airplane with a broken window flying up there and you see everything bieng sucked out?

2. Lets assume we pull out all the stops to get the earth spinning the other way around, strap every rocket we have in the world, as well as get everybody to run in the correct direction, like a treadmill...etc... does that mean that our concept of time weeks, months, etc. is fake?... a fraud theory based on the rotation of the earth, so how would we measure it then assuming even if an asteroid could graze earth with this magnificent force, not damaging the planet or throwing it off course but, just spinning it the other way... one thing i do know is that plants and animals might not notice the difference

2. You could calculate the angular momentum and rotational inertia of the earth (which will be HUGE! considering it's mass). Then it's just a matter of overcoming those forces. I don't know how effective it will be though. The earth's crust is solid (which is fine) but parts of the lower mantle are (plastic = pliable) and the outer core is liquid. Its going to take a lot of work to get the crust to stick to the mantle enough to get it to spin, as well as transferring that to the liquid outer core.

This was my thought too, I think the most you'll do is cause a fark load of earthquakes.

2. Kinda like the clutch on a car? it will need friction, you right because else the outside might spin one direction and the insides the other way... it would definitely feel like a running tummy LOL ,
my main concern about this theory though is about time, how accurate is it, and technically shouldn't it go backwards?

Yea, sorta like a clutch. Its like putting something in a blender, blending it and while all the liquid is turning anti-clockwise you turn the container clockwise. Its going to take quite a while for the liquid to stop and reverse.

As for the question about time, its irrelevant. The only time that you could make time go backwards is by travelling at the speed of light (impossible - your mass would be so huge that the energy required to accelerate you to the speed of light would blow your mind.) The rotation of the earth has nothing to do with time. Only "our" human perception of days (sun goes and comes down).

I disagree. Even if you are traveling faster than light, light is not a measurement of time. Time will always exist, moving forward. Everything might appear frozen I suppose, but it would not actually stop time, nor reverse it. Can you physically move faster than your brain can perceive an image? What image would you then see. My guess is everything would appear black. But as I said, time keeps progressing... particles of light energy will just be moving very slowly or basically you would be moving with them.

Easiest way to think of it is if we were traveling from point A to B, and you were going X times faster than the speed of light. You would get to point B faster than the light that reflects off my body, hence making it look as if I did not move at all. But it still took you time (all be it really fast) to get to point B. And in that time i might have only conceived the idea in my brain to actually lift my feet and start walking, but I sure as hell did not go backwards. Exactly like we are only seeing some stars now at night that are probably already extinct.

2. If you managed to apply enough force to effect a reversal of the planet's rotation there would come a point at which the earth's rotational velocity would be zero & everyone would fall off the earth. The animals would notice.

 

[Tacet]

I'll leave time, relativity and light to Einstein - he was quite good with it.

As for the pipe idea, nope, sorry, it's a pipe dream. The air pressure theory sounds quite cool, but it doesn't hold if you consider what actually causes air pressure: gravity. Gravity keeps everything that's around the earth close to the earth. If it wasn't for gravity our atmosphere would have dissipated into space long ago. That same gravity will keep the oil firmly on Terra. The air pressure diffirential between space and our atmosphere isn't enough to suck up the air away from gravity. And air is quite light...

We aren't held to the earth because it's spinning on it's axis. If anything because the earth is spinning on its axis we should be flung off into space. (Due to centripetal forces.)

However F= (GM(1)M(2))/R^2 Newton's Law of gravitation force states that the force of gravity acting on an object is equal to the product of their masses over the distance squared. We are attracted towards the center of the earth because there is such a large difference in mass between us and the earth.

Well an airplane has this effect as is is pressurized... your pipe won't be...

Well put. Changes my view of things a bit

1. If the pipe was strong enough then only one thing can happen. The oil would go up the pipe. But I don't know if it would stop at a point or if the vacuum would be strong enough to suck it out the other end on second thought if you took a tennis ball and put it in the pipe would it fly up to the top and out into space? Perhaps it would? In that case I don't see why little bits of oil wouldn't do the same. lol. I don't know enough about vacuums

2. If we could change the rotation of Earth that way it would have no effect on time. Only on our concept of time because we would alter the way we interact with the Sun. I'd like to think the molten rock nearer to the core would also spin the other way eventually like a big washing machine suddenly changing direction haha. I suppose it would have some minute impact to strap all those rockets together really don't know.

Also this whole thing with the speed of light and time...I dunno hey. I mean I often reason by taking something to an extreme to try understand what might happen as it gives a clearer picture. Say at point X in space where we are we notice something at point Y which is many light years away and we know by general knowledge that by the time it's light travels to us to observe it it is already so many hours/days past that point. Screw travelling faster than light. The extreme would be to appear there instantly at point Y right now with the snap of your fingers, what would you observe? Well of course the object at point Y would no longer be there obviously.

Simply because you observed it from point X so many hours later does not mean you can outrun it's light and catch it moments before the point of observation. I would say the state of matter as it is now is the same throughout the universe anywhere you look no matter how/when you observe it.

All this is assuming we are bound by the constraints of space and time. Now what if we were 5th dimensional beings, we would then be free/have the ability to manipulate the 4th dimension (time).

Now using this new knowledge, thoughts?
