My question that pertains to this topic is couldn't we find a means producing a rocket that generates enough propulsion to do this?

My Thoughts:

Well there are a few factors that we need to take into consideration, but I'll stick to the most simplistic.

The earth rotates at X amount of miles per minute.
So we would need to stop earth's rotation for a brief duration of time.

Easily done however, attach two of these rockets on opposite sides of the globe to counter act the rotation and stop the rotation entirely.

Next we launch a third rocket to physically move the planet X amount of miles.

Than we launch a fourth rocket to regenerate earth's rotation.

Well some may ask how do we attack this rocket to earth....

Couldn't you bury an anchor roughly half way to the center of the earth?

As for the amount of energy needed to produce the propulsion. Could we not split quarks to do so?

This maybe far fetched, but I don't think its any more far fetched than hurling a huge asteroid past earth several millions of times and risk smashing it into earth.

Also the recently discovered how to amplify the speed of light could we do this with a low heat producing light to say push earth?

Answer 1

Ill bite and say that it could be done. But looking into the mass ratios of rockets, the best rockets for oxygen and kerosene , is about 25:1 thrust to weight ratio…. Earth’s mass is 5.98 x 10 e-24 kg…. so you’d one hell of a BIG ROCKET to pull the Earth.

Answer 2

The link to the question you're following-up doesn't seem to be working.

The title of your question asks whether the earth is moving closer to the sun or farther. You'd know that the earth's orbit is elliptical, so it will be closer to the sun at some times than at others. Now, is this ellipse itself changing? For virtually all practical purposes it's not, but if you look carefully, the earth is *very* slowly moving away from the sun. Details about this are in the reference below.

Now coming to your other questions. All of it is far-fetched to the extend of being impossible.
Let's assume the anchoring is possible (though man has never penetrated to beyond a few kilometres into earth), but then generating enough speed for a rocket of realizable dimensions to produce any perceptible movement of the earth is unachievable. Imagine a rocket of 1000000 tonnes (unimaginable by itself). Here are results of some simplistic calculations on momentum conservation:
* To change the earth's rotational speed (at surface) by 1micrometre per second with two such rockets, each would have to move at 5 times the speed of light.
* To give the earth's centre-of-mass a change in speed of 1micrometre/sec, it would need to move at 20 times the speed of light.
Both are physically impossible.

Sorry to disappoint your fertile imagination, but we don't call Earth mother for nothing...

About the other concepts you speak - splitting quarks and speeding-up light. I'm not saying it's all impossible... but I hope you believe in rebirths also, for you'd need many of them if at all some such thing were to come true.

Here's another fact that may interest you: if you somehow just completely stopped the earth from revolving around the sun, it would fall into the sun, taking 64.5 days for the journey.

Answer 3

it is staying in the same orbit!
