Round earth Gravity vs. Flat earth "Gravity"

LOL @ 6String

Torque develops around your hip retard. And you're making fun of other people's understanding of physics...

Idiots, you couldn't tell whether gravity is pulling you down at 9.8m/s^2 or the ground rushing you at 9/8m/s^2. NO EXPERIMENT AT ALL WILL LET YOU KNOW WHICH YOU ARE ENCOUNTERING.

Except for the little "locality" caveat....

Question: Is the Earth travelling at 9.8m/s-1 or accelerating at 9.8m/s-2?

Question: Is the Earth travelling at 9.8m/s-1 or accelerating at 9.8m/s-2?

The short answer is that (in the flat-Earth model) it is accelerating at 1g.

The long answer is that since there is no absolute frame of reference, it's not meaningful to talk about the speed the Earth is travelling.  If you pick a frame of reference, then you can discuss Earth's speed with respect to that frame.  Thus, if you want to say that the Earth is moving at 9.8 m/s, you can do that; you just have to pick the right frame.  However, since the Earth is constantly accelerating, it will only have that velocity for a single instant.  This is true in both the flat-Earth model and the round-Earth model (in which the Earth is in orbit around the sun and thus subject to a more-or-less constant acceleration).

This website describes IN DETAIL an experiment that will allow you to see the effects of gravity between two rocks, you retard.

If gravity was caused by the Earth moving upwards, and there was no other gravity, then the rocks in the above-linked experiment would not be attracted to each other in a sideways direction.

However, if two rocks can gravitate towards one another, then why do we need this secondary theory to explain Earth's gravity?

LOL, people are so fucking stupid. That experiment has NOTHING to do with what I said.

But doesn't that mean the theory is fundamentally flawed? Since on a round Earth, an object dropped starts with a speed of 0 and falls at a rate of 1g.

But on the flat earth, the earth already has a speed? So if I drop an object now, it will take say 10 seconds to fall. But one day later, the speed of the Earth has increased therefore the object will take less time to fall?

No... as the speed of the Earth increases, the speed of everything on it also increases, since they're all being pushed by the Earth.  The situation is the same all the time.

This exact question was posed in another thread:

http://theflatearthsociety.org/forums/viewtopic.php?t=1102

and an example scenario is given there as well showing that the exact same thing happens due to either round Earth or flat Earth gravity.
