I Mature women Gravity to my car in the parking lot and told myself to turn around, go back in and ask you for your number but couldn't muster up the courage to do so. I just got my haircut today so I am feeling all sexy and groomed haha.

Qomen my fantasy universe, there is a disc-shaped world that has a flat surface that has roughly the same atmosphere as Earth see this ; Mature women Gravity atmosphere moves along with the world.Seeking Milf S For Single Mom Fuck Fun
My question is, would the force produced by this acceleration be effectively indistinguishable from the force produced by gravity on Earth? Would this affect the behavior of airplanes in any obvious way? Your world will experience constant, uniform gravity. Everything is accelerating upward Mature women Gravity the same rate - but this isn't the case in our universe, as Mature women Gravity follows approximately an inverse-square law, and more specifically the framework of general relativity. On Earth, this isn't the case, and there are a number of different effects.
Some are obvious and some aren't:.
Gravity isn't quite uniform on Earth's surface. Earth rotates, and so the equatorial radius is larger than the polar radius by about 22 km, meaning that gravity is stronger at the pole than at the equator. This could have Mature women Gravity Gravltybut nothing immediately visible to the human eye; it's only 0. Local changes in Adult seeking hot sex KY Flat 41301 from surface topology also affect gravitykeep in mind that even Mount Everest is only about 9 km above sea level.
Mascons - local gravitational anomalies - are present on the Moon, but aren't important on Earth, although such deviations Gavity be mapped:. Map of gravity variations on the seafloor. In short, if you travel, a long distance on Earth, you might be able Mature women Gravity see Mature women Gravity difference in surface gravity, but only with fairly good measuring equipment.
If you travel anywhere on this world, you shouldn't see any variations. Gravity also gets weaker if you rise through the atmosphere of Earth, thanks to the inverse-square law.Housewives Want Casual Sex Mc Calla Alabama
Therefore, that change would be hard to measure. The same goes for tunnels under Earth's surface, but even the deepest man-made hole on Earth is only km deep.Adult Seeking Real Sex NJ Lakewood 8701
There have been experiments that have shown that Mature women Gravity relativistic effects indeed change as predicted at different heights above Earth's surface - the Pound-Rebka experiment was a famous one, as was the Hafele-Keating experiment. The former tested changes in gravitational redshift; Mature women Gravity latter tested changes time dilation from special and general relativity. These changes wouldn't be present in your flat, accelerating world. Again, though, this requires sensitive measuring equipment.
Credit goes to Nat for reminding me of this one.
Tides Mature women Gravity Earth arise from the positions of the Moon and Sun in relation to one another. With no gravity, you'd see no tides - even if a moon Horny girls in Guarapuava co star appear in the sky.
Not also that "tidal forces"in a different sense of the word, arise from a gravitational gradient - a difference in the force of gravity between two points. In a case of Mature women Gravity acceleration, you won't see that sort of thing.
Einstein later refined his thought Mature women Gravity to consider a man inside a large enclosed chest or elevator falling freely in space. While in free fall, the man would consider himself weightless, and any loose objects that he emptied from his pockets would float alongside him.
Then Einstein imagined a rope attached to the roof of the chamber. A powerful "being" of some sort begins pulling on the rope with constant force. The chamber begins to move "upwards" with a uniformly accelerated motion. Within the Mature women Gravity, all of the man's perceptions are consistent with his being Mature women Gravity a uniform gravitational field.
Einstein asked, "Ought we to smile at the man and say that he errs in his conclusion? Rather, the thought experiment provided "good grounds for extending the principle of relativity to include bodies of reference which are accelerated with respect to each other, and as a result we have gained a powerful argument Mature women Gravity a generalised postulate of relativity.
If the disc world is perfectly flat, and there are no edges, then the atmosphere will quickly slide off the edge of the disk. If the world has a mile wall around it, then the air will Mature women Gravity in.Fuck Buddies Ananindeua Ierapetra Horney Chat
What accelerates the world discs? Is Mature women Gravity some universal force which propels rock or dirt rGavity So, the obvious way to build a spaceship would be to cut some "world material" out of the disc planet. It would we some sort of anti-gravity transportation medium. The "constant acceleration" premise sound implausible?
No, not at all - it is Mature women Gravity a requirement! The acceleration needs to be independent of the amount of "non-world material" piled onto it.
Otherwise, the world disc would tip as soon as the non-accelerated mass was unevenly distributed across the world. One the disc Mature women Gravity, water and air would Mature women Gravity downwards, causing the disc Girls looking girls looking sex continue to tip even faster. Water and air are other stuff would fall off the disc, with predictable results.
Your "airplanes" would be floating rocks, like air ships zeppelinsbut without the hassle.
They would also be spaceships, but once you leave the atmosphere that would Mature women Gravity easyregular control surfaces do not work any more. Once you leave the wold disc area floating sidewaysyou Gravty reaction drives.
Now, that sucks hard They can just launch material into the opposite direction to generate thrust into the desired direction.
Not an issue Mayure long as Casual Dating Nelliston use "floating rock" material Chances are good that, eventually, some other world will get hit by a turd Mature women Gravity at hyper-relativistic speed. So only the "top" worlds in the infinite universe would be inhabitable at all. Mature women Gravity there are no other cosmic bodys in your universe, you also have no Sun.Chicks In Reading For Sex
Mature women Gravity Sun means no sunlight and no sunlight means your world will have a temperature as close to absolute zero as Heisenberg permits. Apart from geological activity [which shouldn't exist Grravity Mature women Gravity, in my opinion] and radioactivity, if it should exist.
Matture Home Questions Tags Users Unanswered. Simulating gravity in a gravity-less universe Ask Question.
Giter Since this universe doesn't have gravity, they're probably tossing relativity, too. TrevorD You'd never reach the Mature women Gravity of light - consider the relativistic rocket.
That's the funny Mature women Gravity with relativity, you can accelerate forever and yet you will never reach the speed of light. In fact, you will always see light go at the same speed in Mature women Gravity direction. And as the universe is empty anyway, there won't be any other meaningful referential where the world is going at ridiculous hyperrelativistic speed.
Which Mature women Gravity good, because at some point any particle would punch a hole through the world at some point otherwise. TL;DR Your world will experience constant, uniform gravity.
Some are obvious and some aren't: Gravity varies across Earth's surface. Gravity varies at different elevations. Gravity varies over short changes in height - measurable with sophisticated Mature women Gravity. Tidal forces arise from differences in gravity between multiple points. Changes in surface gravity Gravity isn't quite uniform on Earth's surface.
Mascons - local gravitational anomalies - are present on the Moon, but aren't important on Earth, although such deviations can be mapped: Changes in Maturr atmosphere Gravity also gets weaker if you rise through the atmosphere of Earth, thanks to the inverse-square law. Small-scale changes There have been experiments that Chat line Model md fuck shown that general relativistic effects indeed change as Mature women Gravity at different heights above Earth's surface - the Pound-Rebka experiment was a famous one, as was the Grqvity experiment.
Tides and tidal forces Credit goes to Nat for reminding me of this one. Unless the flat world is engaged in a cosmically huge banking manoeuvre of some kind JoeBloggs That would explain Mature women Gravity some scifi spacecraft move. While Earth's gravitational Mature women Gravity may vary by 0. I used some of those numbers in my answer to A moon that is hard to orbit. And I coincidentally just mentioned mascons in my edit.
Tides could be simulated if the flat world was slightly tilted and that tilt kept rotating around it's vertical axis.
Would this effect the behavior of planes in any obvious way? I upvoted, but Mature women Gravity like to note that this only holds in a uniform gravitational field - true locally on Earth, but not globally.
HDE given Mature women Gravity it's Maturs gravity-free universe, and the disc is accelerating at 9. I mean that the Earth's gravitational field isn't uniform, whereas this world's is. In other words, at any given point, Einstein's thought experiment holds, but Mature women Gravity you travel across Earth, you'll see different effects due to different strengths of gravity. That won't be the case on this disk.
HDE also, yes, it's uniform gravity, but You got me there. Klaws 2 6. Thus, your planes couldn't take off, since there wouldn't be a gaseous atmosphere available. It seems to me the sun isn't the only thing that warms us on this planet; there's also heat coming up from below. Still not Mature women Gravity you Mature women Gravity conclude it's so cold.
This is a different shaped world, with other forces besides gravity at play; who knows what led to the world's formation and what temperature it Mature women Gravity.
In fact I'm not even sure it makes sense to say there isn't gravity, since there is a force that walks and quacks like a gravity.
