It's been a while since I did physics so if anyone who's not Gothboy77 could correct me on anything I'm about to say I'd appreciate it --- Quote from: Goth77 on November 05, 2017, 11:49:39 PM ---It makes sense to me. If your sandwhich was comprised of something like helium then it would float. I guess "gravity" only applies to certain sandwiches. --- End quote --- This is not a complicated concept. The helium balloon rises due to the Archimedes Principle. "Any object, wholly or partially immersed in a stationary fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object." It is the same reason that a balloon filled with a heavier gas will float on water, because it is buoyant, whereas a balloon that is full of lead will sink, because gravity is acting on lead with a greater effect than it is on the balloon of heavier gas. You can very easily test this theory by picking up a balloon full of helium and picking up a balloon full of lead and determining for yourself which one is harder to move. The helium balloon floats because the force of it's buoyancy is greater than the force of Earth's gravity acting on it. This is effective so long as there is a heavier gas (air) for the balloon to rise in. When it reaches higher into the atmosphere, where there is less gas, the balloon will stop rising as the force of it's buoyancy becomes less than the force of gravity. Here's a neat picture that might make this concept easier: Fg is the force of gravity. Fg is calculated as mass x gravity. This is the formula your bathroom scale uses to determine your weight. Fb is the force of buoyancy. Fb is calculated as the mass of the fluid displaced multiplied by the force of Earth's gravity. So, essentially, you would get the volume of the balloon, calculate how much that volume of atmosphere around the balloon would weigh on Earth, and that would give you the buoyant force. Here's a question: What prevents the very non-dense atmosphere of Earth from simply dispersing into space? What holds the sun, a big ball of helium just like in the balloon, together? --- Quote from: Goth77 on November 05, 2017, 11:49:39 PM ---So your telling me that you would believe my words over a perfectly legit scientific article I just linked you to? Your suggestion does not sound like it would work very well --- End quote --- No, I want to respond to your argument, not Dr. Verlinde's argument. I have no problem with Dr. Verlinde's theory. According to this quote: --- Quote from: Goth77 on November 05, 2017, 11:49:39 PM ---It is very much theory, and no --- End quote --- The argument you are making has absolutely nothing to do with Dr. Verlinde's theory. Yes, Dr. Verlinde said "Gravity does not exist". Issac Newton and Einstein both said it exists however. As a matter of fact basically every scientist on the planet says gravity exists. So, according to your stuffty standard of evidence, I don't even need to prove the existence of gravity, because the standing authority already agrees with me. One moron saying it doesn't exist for attention does not equate to scientific proof that gravity does not exist. Here are two experiments that were conducted in the 1800's, a time when we didn't have incredibly accurate measuring technology, that were used to prove the existence of gravity: https://en.wikipedia.org/wiki/Cavendish_experiment https://en.wikipedia.org/wiki/Schiehallion_experiment If you were to conduct both of these experiments yourself correctly you would achieve the same results. With a bit of willpower you can construct the apparatus used in the first experiment in your backyard. Scientific proof that gravity doesn't exist would make you a very rich and famous man, so no excuses, get building! |

Again, things do not sink in liquids unless there's gravity. Bouyancy is only an upward force. Density doesn't make things move unless there's a field that exerts forces on things with masses. Also known as gravity. |

Yes the guy is a "flat earther" but I found the video when I was searching nasa stuff these dudes look similar --- Quote from: HellHound on November 05, 2017, 11:52:42 PM ---helium isn't a solid though. density is relevant for fluids interacting, not a solid and a fluid like air. balloons with helium are lofted because the lower density of helium creates a pressure difference at the top and bottom of the balloon that pushes it upwards. if you actually knew a thing about physics or gas laws, this "discussion" wouldn't be happening. --- End quote --- pretty sure a solid and a fluid "interact" with density. An apple generally floats in the water, but it does not float in air. --- Quote from: Foxscotch on November 06, 2017, 12:20:03 AM ---if u genuinely believe gravity don't work like the Scientists say it work, then ur a fool frankly. stuff you use probably on a practically daily basis relies on that sorta thing. GPS uses satellites, which first of all A: gravity obviously caint work just cus of "density" cus there aint no forgetin air in space and B: all of that general relativity stuff einstein came up with, GPS relies on knowing those facts in order to get you the info you need. if GPS didn't account for time dilation, it'd get 10km off every day. but ok einstein and everybody else is wrong despite knowing loads stuff more about this than you ever will cus you decide you want an explanation that is simpler for you to understand and if you dont believe in satellites or whatever the forget then forget u honestly --- End quote --- GPS = trilateration + triangulation through cell phone towers/wifi forget you too buddy! --- Quote from: Rally on November 06, 2017, 12:32:33 AM ----snip- --- End quote --- should I link you to my go fund me, or do you prefer patreon or kickstarter |

It's not surprising that density is your catchphrase |
