The changes of pressure are a result of gravity. Air and water have substance (matter). That matter is affected by gravity just as a large rock is. When there is air or water above you it is pressing down on you creating pressure. The more air or water the greater the pressure. because water is denser than air we feel the pressure changes more as we move up and down a water column. A sealed container is equalized to the pressure that it was sealed in. If it experiences more pressure by going under water or to a lower elevation it has a tendency to collapse inward as a result of the pressure. On the other hand if it was sealed under high pressure and moved to an area of lower pressure it has a tendency to expand or explode. What causes gravity? |

I think if we knew that we could control it
anti gravity inertialess drive the holy grail of space travel |

Gravitation: Objects with mass attract one another. It is a natural phenomenon.

Gravitation: Objects with mass attract one another. It is a natural phenomenon. What causes it? Labeling it "a natural phenomenon" does not tell me much. I really would like to know. |

I did not label it a natural phenomenon that is just what it is. All matter is attracted to other matter.

I did not label it a natural phenomenon that is just what it is. All matter is attracted to other matter. It's a label, its not an explanation. If you don't know the answer just say so. Your statement does not answer the question. HOW AND WHY IS all matter attracted to other matter? |

I did not come up with it. I looked it up and that is what it is called. A natural phenomenon.
It is good that you are curious but there is no answer. |

Well I can't have a lot of faith in science and scientists if they haven't even figured out what causes gravity. I think when they do, they are going to be very surprised. |

Space is infinite but the universe is finite. Because the universe encompasses everything that exists (all matter) and beyond that is just space. we don't know that. when astrophysicists refer to the universe they are speaking of the "visible universe" or "observable universe". we only have evidence that suggests what has happened since a few milliseconds after the event we call the big bang. we have no evidence to suggest what happened precisely at the time of the big bang or before. nor do we have evidence that might suggest that there was only one big bang. could many have happened simultaneously or are several, even an infinate number, be happening concurrently? we simply don't know. |

You got that right!

mass more mass equals more gravity But how does mass cause gravity? we could spend quite a bit of time and i'd be happy to describe to you how i understand that mass causes gravity. i've many books and references on the physical sciences that has diagrams and grafts that can help you understand. then we could go into how an airplane defies gravity if you wish. but there is no simple answer to the question "what is gravity and what makes it happen" and most on the forums get bored easily with anything other than simple answers. but you know how to reach me if you really want to understand the physical sciences. as i understand them at any rate. if i'm no help to you, i can refer you to a friend who's working on his phd in theoretical physics. you might be interested in his doctor's dessertation on quantum mechanics. won't help you understand gravity though. |

I'm afraid if I spent all that time learning about what they think makes gravity work, then they will discover they were wrong and have to rewrite the book on it. I'm looking for a more simple explanation. I think if it is all that complicated its because they really don't know for sure. |

I'm looking for a more simple explanation. I think if it is all that complicated its because they really don't know for sure. bingo bean. they don't know for sure. you just described science in a nutshell when you said those five words. and a vast majority of folks on this forum don't get it. scientists don't know for sure. and they never will but i thought your question was along the lines of how does physics explain why a mass exerts gravitational pull. as i said, there is no easy explanation and yes the way it is explained today is in question as to it's accuracy. scientists do keep changing their minds don't they? just look at caffene. a few decades ago some scientists were convinced it caused heart disease. no those same researchers are finding it to be a wonder drug not only working to reduce the risk of heart disease but ward off such things as alzheimers. gravity went through the same thing. for more than three centuries newtons laws of gravity, momentum and motion were the gold standard in science. then a few decades ago einstein found newtons conclusions to be mainly bull crap and general and special relativity was the result. now einsteins postulates are being questioned by hawkings and others. it never ends. therein lies the real beauty of science. there is no end to the learning. only when you believe something to be true or fact have you ceased learnng about that particular something. that's why a good scientest realizes that nothing can ever be proven as fact and will experiment tirelessly to create that one unpredicted result that disproves a theory. |
