    I read almost the exact same story, but what he sees in the box seems to be the whole Earth, spinning rather rapidly, then the Earth shoots something at him and hurts his eye, in a fit of anger he picks up a red hot poker from the fireplace and jams it into the box. The next week a giant eye appears over the entire sky.

    32 ft per second wouldn't be enough, would it? The actual speed of a falling object is 32 ft per second, per second That is, it's not constant. its 32 ft in the first second and 64 feet in the second second and then 96 feet per second in the third second, yes? But if what you say is the way things really work then nothing would ever fall faster than 32 feet per second, ever.

    I'd like to propose a counter theory which this inspired, however. Mine is that the reason gravity is so weak is that the gravity of dark matter, which, according to physicists composes around 94% of the Universe, is negative, and so cancels most of regular gravity out.

    If I work out the math, I'll share the Nobel Prize with you.

    Everyone knows,

    Gravity Sucks !

    I've never heard the earth's radius is expanding by 32 ft./sec./sec. Which makes the thread's premise questionable. What we do know is that the remnants of the Big Bang will continue moving away from one another rather than eventually collapsing back together, as might have been supposed. The expansion rate is far greater than 32 ft./sec./sec.

    We're talking about 2 different things, I think. The rate of expansion very close is only 32ft/sec/sec. very far away from the "bang point" it must be much faster relative to where we are but very far away is still 32ft/sec/sec but 32' is a WHOLE lot bigger (far away) since it expanded for a long long time. And since we're seeing light from a long long time ago, maybe it's the same size of 32' relative to where we are. And this number alone can reach a very fast speed over billions of years since it's always accelerating.

    And I know I don't explain it very well.

    Is this your personal science (Gravitational Mysticism), or are you citing reputable sources? I'd like to read any sources.

    Look at the link... about halfway through the wiki link above is Einstein's ideas on fictitious gravity. The "dummies" link just explains that you can't tell the difference between gravity and acceleration so IMHO there is no difference.

    The Earth is not expanding. If it were, GPS wouldn't work, ships and planes couldn't navigate correctly, and all our records would show a difference.

    This is a nonsense hypothesis that could very easily be detected and measured - it hasn't been.

    You sound pretty confident in your opinion. But how do you really know or not if it's completely undetectable, meaning space compensates for all the expansion by gettin' the hell outa' the way.
    Did I forget to mention that EVERYTHING expands, especially your tape measure.

    Material attraction (gravity) is the consequence of mass moving through time not space.

    I'm pretty sure that Einstein proved that time and space are inseperable. That's why it's called time-space. Did you just make that up?

    My statement is not at odds with your observation. Even as aerodynamics are primarily resultant of matter moving through space, gavity is resultant of matter moving thorugh time. Of course, one cannot move thorough one without going through the other; however, time and space have different affects of matter.

    Does that mean that you agree that when you let go of a suspended ball, the earth comes up to meet it rather than the other way around?

    How ridiculous. This conflicts with your other assumptions. If everything is expanding, including my tape measure, as you put it, then releasing a suspending ball should do nothing. It would just seem to hover in mid-air, since the Earth, ball, and all space in between would be expanding.

    Your ideas fly in face of all physics. You need to think things through much more thoroughly.

    No. More mass = more gravity. Spinning does not generate that much mass, and the earth is not expanding at 32ft. a sec. Think of spinning pizza dough, does the pizze dough really have more mass when spinning in the air? No, it doesn't.

    The only time that objects gain substantial mass, related to velocity, it as relativistic speeds near that of light.

    How ridiculous! If everything is expanding by the same percentage (mass being the key factor here) then it can't be proven or disproven by any method I know of.

    Space is expanding, as in space between space is expending.

    Objects are not expanding.

    Unfortunately this thing is more complex than you think. Nothing is really “blowing”. Einstein’s gravity is a property of curvature of a spacetime. And nothing really expands but Universe, meaning distance between galactic clusters is growing, but it is completely different story. Please, do not play in physicist, at least when people are watching.

    Who said spinning generated mass? Not me. All I'm claiming is that the entire universe is expanding, and not just because of some red shift... that's something altogether different. This is RELATIVE expansion. And it has nothing to do with food. There is no mass that is expanding (that we can tell) in percentage more than any other mass (relative to each other). If two object expand by the same percentage then you can't prove or disprove that either has expanded... except by gravity.

    I think, by the links provided that Einstein clearly stated that you cannot tell the difference between acceleration and gravity. Sounds like he was saying that there is no argument that the earth (and everything else) could be expanding at the same percentage... at least no argument you can PROVE.

    Which is moot because the earth is not gaining 32ft. worth of mass every year.

    This sounds oddly familiar, like a video on YouTube that argued the break up of Pangaea was due to the physical expansion of earth, opposed to plate tectonics.

    You are confusing different concepts. Cosmic inflation and the introduction of dark energy does not mean two objects are getting bigger.

    Space itself is getting bigger.

    OK, OK, it's expanding...

    Space is nothing more than position relative to matter.

    And I'm not claiming anything different. And just because space is getting (slightly bigger) has nothing do with what I'm talking about. What I'm talking about is accelarating expansion of ALL things... and it can't be detected in any way I or Enstein could imagine.
