I think I found a hole in Physics!!??!!
Supposable all things fall at the same speed when acted upon by only gravitational forces, and unless i have been mistaken an objects gravitational pull is directly proportional to its mass. So if you drop two objects simultaneously in a vacuum, one of which has a larger mass, according to current laws the should both hit simultaneously. I believe this statement is incorrect. My reasoning is this. The more massive object has a gravitational of its own the is minuscule but there and its gravitational pull is larger than the less massive object. So now we have this Two objects falling in a vacuum, Object 1
the more massive object and object 2 the less massive object, they are both pulled down equally by the Earth's gravitational pull, but object 1 is pulling on the Earth with it's grav. pull and so is object 2 but object 1 has a stronger pull than object 2 therefore the is more force pulling object toward the Earth than there is pulling object 2, so in theory the should be a difference in the both objects arrival time, so object 1 falls faster than object 2.
I am fairly sure that i must have missed something and would love any input anyone has to offer so please give me your thoughts.

True.
Zitat von Jakeman235
Both will hit at the same time. An object with lower mass will have weaker gravity but based on the ratio of its mass and the amount of pull it will be exerting and receiving it is the same as an object with more mass.
Zitat von Jakeman235
It takes less energy to move an object with lower mass then one with more. The greater mass will have stronger gravity to "pull" with and needs more force to move.[IMG]http://img209.imageshack.us/img209/6671/siggd6.png[/IMG]

Ohh I knew I missed something just couldn't figure out what. **** I thought disproved physics. lol Anyway thank for the input.

This experiment has been performed and the theory proven many times.So if you drop two objects simultaneously in a vacuum, one of which has a larger mass, according to current laws the should both hit simultaneously. I believe this statement is incorrect.
A feather and ball were dropped on the moon where the atmosphere is a vaccum,
and there is also the penny and feather in a glass tube experiment.

Not to mention gravity isn't dictated by the mass of the smaller objects but the mass of the larger object [Earth in this case]
Or at least the distortion of space caused by the Earth.[fieldset=Interesting Links][url=http://qjwiki.net/index.php?title=Special:Random][COLOR="Red"] Random Page from the QJ.NET Wiki![/COLOR][/url]---[url=http://blackanduril.googlepages.com/home][COLOR="RoyalBlue"]Decompressed RCOs[/COLOR][/url]---[url=http://endlessparadigm.com/forum/showthread.php?tid=167&pid=1764#pid1764][COLOR="Orange"]RCO Editor 1.15C PNG SUPPORT![/COLOR][/url]---[url=http://forums.qj.net/showthread.php?t=90916][COLOR="green"]Ultimate Downgrader Guide[/COLOR][/url]---[url=http://forums.qj.net/showthread.php?t=92230][COLOR="SlateGray"]Recovery Menu FAQ[/COLOR][/url]

Well... the smaller object's mass still has an effect, but when put on the same scale as the larger object (e.g. feather vs. planet) it's small enough to be negligible in all but the most sensitive situations, like things occuring on quantum scales.

well, you are "right", but it doesn't disprove physics.
Zitat von Jakeman235
the experiment with the havy ball and the feather falling at the same speed in vacuum, just shows that gravity just causes a certain acceleration, which is independent of mass.
ofcourse you're right when you claim that the heavier object will have a bigger amount of gravity of itself, but with simple experiments like a bowlingball and a feather, the difference with the earth is so huge it doesn't matter. (if we'd compare the moon and a feather, i don't really know what exactly would happen ^^. the earth would also be moved by the moon a bit, the feather has 2 things attracting it, both earth and moon, etc...
)
it's an original thought, but not really disproving anything. all the experiment is supposed to show is that gravitation just causes an acceleration, that is thus independent of mass. all your reasoning says is that the gravitation in both cases isn't completely equal, so they won't fall exactly as fast, which might be true, but doesn't disprove anything, the same speed of the feather and the bowling ball in a vacuum isn't a phyqical law (last time i checked
). it's only true if they both have the same amount of force on them, and when considering their gravity the forces might indeed be slightly different, so it just shows that the experiment isn't 100% accurate (but 99.9999999999 ought to be enough for anyone
)
and besides, would the ball drop faster, or would the earth be dropping a tiny bit towards the ball? gotta love the fact that everything is relative, what is standing still when you take both gravities into account?
