Gravity and the big bang
I do not know if this is an existing theory, I
only came up with it today, so please bear with my ignorance. Consider the moon (since its diameter is so much smaller than the Earth's and its gravity is so much less). Lets say we were (hypothetically) to send a drilling team up there and drill from surface to the core. What would the gravitational effect 1 inch from the center or even at the center? In essence, what anomoly might we find period? The big bang theory postulates the matter came into being from a single point in space and is forever ex- panding. I am unaware of any measurements to prove that the gaps between stars are increasing. Perhaps someone can help me with that one. Barring that, imagine that a singular event was not the case for matter in the universe, but rather many rips in the time/space continuum, created perhaps by a vorti powered by some unbeknownst celestial event in an alternate dimension. Following this, logic, perhaps many of these events occured and continue to occur (black hole?). It could be postulated that many of the planets surrounding a star were chunks of it flung off during its birth, dragging with it a remanant of that rip in space fabric. Or the planets could be results of their own births, traveling in close enough proximity to a nearby star to get caught in its gavitaitional pull. So, Perhaps what we would find at the center of the moon would be space/time rip, in which case, anything not solid enough to resist destruction might be sucked into an altenate dimension with super-pressure. Thus, what we experience as gravity would be the force of a space time rip trying to close itself. |

An elementary textbook which discusses Newton's law of gravity should show why this happens. The big bang theory postulates the matter came into being from a single point in space and is forever ex- panding. I am unaware of any measurements to prove that the gaps between stars are increasing. The gaps between stars aren't increasing, but the gaps between galaxies are. This has been known since the 1920's. An elementary textbook on astronomy which discusses the cosmological red shift will give the details. Perhaps someone can help me with that one. Barring that, imagine that a singular event was not the case for matter in the universe, but rather many rips in the time/space continuum, created perhaps by a vorti powered by some unbeknownst celestial event in an alternate dimension. Hm. You could be thinking of the brane theories. If so Steven Hawking's Universe in a Nutshell might give you a start. If you aren't, it looks as if you have been watching too many third-class science fiction films. Following this, logic, perhaps many of these events occured and continue to occur (black hole?). It could be postulated that many of the planets surrounding a star were chunks of it flung off during its birth, dragging with it a remanant of that rip in space fabric. Or the planets could be results of their own births, traveling in close enough proximity to a nearby star to get caught in its gavitaitional pull. The first planets weren't formed until long after the first generation of stars died, and that didn't happen until long after the big bang. The earth wasn't formed until about 9,000,000,000 years after the big bang. Gamow wrote a book entitled The First Three Minutes, a popularisation of the big bang theory, published in the late 1940's IIRC. This gives half the story. Fred Hoyle wrote a popularisation in the 1960's that give the other half, but I can't remember what its title was. A textbook on cosmology will give you the details, but it is unlikely to be elementary. So, Perhaps what we would find at the center of the moon would be space/time rip, in which case, anything not solid enough to resist destruction might be sucked into an altenate dimension with super-pressure. Thus, what we experience as gravity would be the force of a space time rip trying to close itself. I don't think you know what a dimension is. I seem to remember something in Twilight Zone like this, but that was 40 years ago and my short term memory isn't what is was. |

At the center, there is no net gravitational attraction from the mass of the Moon. In effect you are within a spherical shell, and inside a spherical shell, it so happens that the mass on one side always cancels out the mass on the other side is far as gravity goes. One inch from the center, it would be similar -- you would experience only the gravity of the 1-inch-radius sphere at the center; everything outside of that counts as a spherical shell you're within. In essence, what anomoly might we find period? None. The big bang theory postulates the matter came into being from a single point in space and is forever ex- panding. I am unaware of any measurements to prove that the gaps between stars are increasing. Really? I thought everyone was aware of those measurements. They're very old, dating back to Hubble (the astronomer, not the telescope).

You can think of gravity as a dent in spacetime, but I don't see how it could be described as a rip. Best, - Joe ,------------------------------------------------------------------. | Joseph J.

As you descend through a homogenous spherical body, the gravitation is equivalent to that of a body the size of the distance you are from its center. snip So, Perhaps what we would find at the center of the moon would be space/time rip, in which case, anything not solid enough to resist destruction might be sucked into an altenate dimension with super-pressure.

How do you account for the fact that the center of the earth is liquid. Any "rip" would over the many billions of years since the earth coallesced have eaten it. |

So when the space time rip finally closes gravity goes away?
Anything that gravity doesn't affect must have drifted away long ago. If we can go find some of that stuff and build a space ship out of it it would save a lot of trouble. It's my theory that the stuff exists. "Phych" wrote in message ... I do not know if this is an existing theory, I only came up with it today, so please bear with my ignorance.

It is, of course, the field of the body to which you refer; the total field at the centre of a tennis ball is one gee. In that case, symmetry alone is sufficient; any symmetrical law of gravity would give the same result. The interesting result, requiring the inverse square law and otherwise only elementary arguments, is that the field *anywhere* within a homogeneous spherical shell due to the shell is zero. I lack an equally elementary argument for the field outside a spherical shell; but I have Ramsey's version of Newton's. ISTM that the self-field at the centre of gravity of an unsymmetrical body is not in general zero. Consider the Earth and Moon to be a single non-rotating body joined by a massless stick. It is well-known that the centre of gravity is within the Earth; and the zero-field point must be near L1, some 300,000 km or so away. The first planets weren't formed until long after the first generation of stars died, and that didn't happen until long after the big bang. The earth wasn't formed until about 9,000,000,000 years after the big bang. Gamow wrote a book entitled The First Three Minutes, a popularisation of the big bang theory, published in the late 1940's IIRC. Steven Weinberg wrote a book of that name and topic, in the mid- seventies. Gamow had no such book in print in the UK in 1987. This gives half the story. -- © John Stockton, Surrey, UK.

Everyone else has pointed out problems with your idea, which I cannot add to,
but I will point out a fallacy in your thinking not mentioned. To whit: Phych wrote: [stuff deleted] The big bang theory postulates the matter came into being from a single point in space and is forever ex- panding. I am unaware of any measurements to prove that the gaps between stars are increasing. Perhaps someone can help me with that one. Barring that, imagine that a singular event was not the case for matter in the universe, but rather many rips in the time/space continuum, created perhaps by a vorti powered by some unbeknownst celestial event in an alternate dimension.

Or the planets could be results of their own births, traveling in close enough proximity to a nearby star to get caught in its gavitaitional pull. [rest deleted for brevity] No, the big bang theory does not postulate that matter came into being from a single point in space and is forever expanding. The big bang is the creation of space and time. There was no preexisting void to fill as you imply. That effectively negates the rest of your speculation, scientifically. As to planet formation, look at the protoplanetary disks found in the Orion Nebula to see that process (there are nice images of it at the Hubble Space Telescope site). Planet formation seems to be the result of the collapse under gravity of fragments of gas and dust within an even larger cloud, with disk formation due to the spin of these fragments during collapse flattening the fragments out. If you really are interested in what the big bang theory does (and does not) say, I recommend the following site: http://www.astro.ucla.edu/~wright/cosmolog.htm |

Are you saying that all spherical bodies have their own gravitational field, simply based on their spherical shape, and perhaps density and size? |

Any "rip" would over the many billions of years since the earth coallesced have eaten it. Thanks to all for your well crafted responses. My thinking is a laymans mix of reading discover mag & a little sci-fi. Such things inspire the imagination in well admimistered doses. As for liquids, remember that a liquid is still a liquid despite it viscosity, and a liquid of dense enough viscosity will not pass through a small enough opening, where pressure is not sufficient to force it. In my scenario, the viscosity of the liquid core of the earth would exceed the force to eat it. As for the tennis ball, (I wrote also in another response) does a tennis ball have gravity simply based on its spherical shape, mass, and density? If true, I suspect measurements have been taken on such isolated bodies. I would like to read further on that subject. Any references? |
