I'm not sure you're write about that...

I think that the ashes would stop around the centre of the molten core..... Yourself?

I don't suppose it would strengthen my case if I said I would be wearing this humungous air conditioned asbestos suit. Maths has never been my strong point so I can't prove this. All I can remember is that a falling object accelerates at a rate of 32 feet per second squared. So if you did get to the center, without getting killed by bouncing off the tunnel walls (oh forgot, it's also a very wide tunnel) then you could be travelling at an enormous speed at the center which could maybe overcome the opposing gravitational pulls? I don't know the original source, it was an article in our local paper. And of course there is that non-mathematical proposition that, a priori, if something sounds too good to be true, it probably is.LOL

I think we can dispense with vaporization at the centre of the earth by plotting an FTL jump troposphere to troposphere.
This would of course have to be an equatorial jump to ensure geomagnetics don't scramble navigation and cause us to materialize inside the planet.

That sounds entirely plausible! That is likely what happened to your navigation instruments near the Ionian Nebula, I shouldn't wonder.

There is always some energy loss in any system.

I disagree. The law of conservation of energy states that energy may neither be created nor destroyed. Therefore the sum of all the energies in the system is a constant.

This only applies to an isolated system.

If the universe is completely self-contained and there can be no transfer of forces into or out of it (debatable), then the universe is an isolated system and you have the single exception that make my rule.

Nothing else is. Any smaller system than the universe will either be losing or gaining energy (both at different rates, most likely). At least until entropy prevails.

And I said loss of energy, not it's destruction.

 

[KevinJS]

I concede; transformation of energy is equivalent to a loss of energy here. The net result is the same.

One thing that everyone seems to have overlooked here; when you bore a hole right through the center of the earth to the other side, what's stopping that hole from turning into the largest volcano in the solar system as the liquid core, which is under tremendous pressure, rushes to the surface through the holes.

Can you stand some more numbers? If you could fold a piece of paper 51 times, its thickness would exceed the distance from here to the sun.

Not sure if that is true. Forgive me, but I think you have it wrong. No, I know you are wrong. Definitely not correct.

The old problem had something to do with not being able to fold a piece of paper so many times rather than how thick it becomes after each fold. As the thickness grows it becomes harder to fold and eventually, it becomes impossible to fold the paper again. Regardless of how big the paper is.

You could take measurements and do the math and determine if it is true or not. For example, determine how small the paper is after each fold. Then cut up a piece of paper and stack the pieces and see if they reach the sun. You wil loose some surface area due to the ever increasing thickness of those folds, so take that into account.

The formula is N=4.546 (P) x 4 +ra * Distance to the sun (represented by 4 x 10 x 100 xP ie R squared) x r +n 12th sq X 3.445/a+B+N sub Variable x brand of paper + thickness +4 x color

A 12 x 12 paper folded gets you a 6 x 12 page. Try it now, grap a sheet. Fold that and you end up with a 3 x 6, so on and on. There must be a math wiz who can report how small the surface area is after 51 folds. Then add up each piece of paper and see if the pile is 92,960,000 miles high.

I feel confident saying you are mistaken.

That claim also applies to Colorado, New Mexico, and Arizona.

View attachment 31595http://en.m.wikipedia.org/wiki/File:Four_Corners_Monument_Marker.jpg

Nope . . . just look at a map. We border 4 states, but neither Colorado nor New Mexico nor Arizona borders 4 states. You just think they do but you are not correct. Besides, with Bing on my side I am seldom wrong. I am right, I tell you. Right as rain as they say. Stop picking on me, it is Christmas time.

Well, it is impossible due to pressures. Tremendous pressure down there and any hole you drill would collapse. Unless you use special technology; it can do it all.

Sorry for the tone. I just got done reading a rather combative usenet group and some of it rubbed off.

Assuming enough of the body remains a solid near the core (highly unlikely):

Wind resistance would be the only thing slowing the body as it approaches the center. An object does not slow down because gravity decreases, it only accelerates more slowly.

At some point the body would reach terminal velocity; the point where wind resistance counters gravity's acceleration. As gravity decreases that point will get slower and slower, however it would not be zero at the center. How fast the body would still be going I don't have the math to make an accurate (or even semi-accurate) guess. It would keep going until the the now rising gravity overcame the remaining velocity. At that point you'd have the same situation in reverse, with less energy. And you'd bounce back and forth a bit like a rubber band, going a bit slower with each cycle until you ended up at the center anyway.

If you eliminated the wind resistance and the heat, you'd could bounce back and forth (end to end) forever, or there abouts. There is always some energy loss in any system.

Doesn't terminal velocity apply to free falling throughout the atmosphere? Down there, it is solid rocks and lava and that giant spinning ball of iron or perhaps it is melted iron.

I take my clues to those gals that wrestle in jello. They can wrestle faster in the air, but the jello slows their actions. So, they would not only be crushed on their way through the planet, but their movement would be slow. if you were on a giant ball of rock with a Jello core and two wrestlers were wrestling throughout their journey through earth, they would be slowed down as they pass throughout the various time zones. So they might never arrive in the first place. Or they would be really late.

I say you cant drill a hole through the earth because the earth is spinning and when you drill and the bit breaks through the other side, the rotation of the earth might mean that the drill stabs you in the behind. Do the math, I must be correct.

LOL . . . one of the last usnet groups I played with ended in a great battle over Cellulose Nitrate and Cellulose Acetate and a few pen makers. Can you believe it? I really cheesed their pizza, so I feel good about that.

Given enough time and every discussion ends with anger and someone will be called Hitler. I never take your tone as anything other than pleasant. OK, you are usually wrong o) p) o) but you make that look good. Santa will not put coal in your stocking, trust me.

Do not fret so, sweet poison. As long as you keep the house clean, remain quiet and walk two steps behind the man of the house, you can be ditty as you like. After all, you are blond. And you know what they say about blonds, right? No, how could you, you are blond.

LOL
