Can anyone tell me why my feet stay on the ground?
Nice try but that response,(not to be too unkind), seems as something you saw on TV. You cannot talk two dimensionally about a three dimensional space. That's too much of a stretch. Plus, that does not explain why this man/woman is attracted to earth, really.Legion81 said:If you hold a piece of paper so it is stretched out, then place something heavy in the middle you will see it sinks down. Now if you were to place something lighter on the paper it falls to where the heavier object is. That is exactly what happens in space, you are falling toward the heavier object... the earth.
Actually, string theory is not completely accepted yet like let's say Newton's law of Gravity. So to talk about string theory as if it is completely solid intellectually is jumping the gun a little. Furthermore, no graviton has been detected as of yet.scoobydoo said:I understand that concept yet it still puzzles me the fundamental physics of why that happens. Doesnt string theory predict the Graviton particle as some kind of explanation?

scoobydoo said:I was just thinking about how gravity by special relativity is a wave that travels at c, and correct me if I am wrong but theories think that the graviton could possibly be part of this wave. what if mass not only curves space time but also creates ripples in space-time and this is what we see to be gravity? Everymodel i see is a flat space-time curved by a large mass, but in reality wouldn't it make more sense if space-time were to ripple, such as the surface of a pond. The question is which direction would the waves be traveling in, towards the mass or away form the mass. I'm thinking towards the mass and Earth is traveling into this wave like a boat sailing into a wave on the ocean of course though the Earth would simultaneoulsy be traveling perpendicular to the wave otherwise the Earth wouldn't orbit the sun, the only kind of earthly comparison i can think of is that of a whirlpool. Let me know what you guys think!

Acceleration = change in velocity over time
If a lump of matter can alter space, why not time (Spacetime?)
A gradient in the "flow of time" of one thirty millionth per second per second just might yield an acceleration of 10 meters per second per second.(1G.)
This is almost certainly wrong, but I'd really like to know why
Gravity is a natural force that pulls objects towards each other. It is responsible for keeping our feet on the ground and planets orbiting around the sun.
Gravity is the force that pulls us towards the center of the Earth. It is constantly acting on our bodies, which is why our feet stay firmly planted on the ground.
Gravity works by the principle of mass attraction. The more massive an object is, the more gravity it has and the stronger its pull. This is why larger objects, like planets, have a stronger gravitational force than smaller objects, like humans.
Astronauts appear to be floating in space because they are in a state of free fall. They are constantly falling towards the Earth, but their horizontal velocity keeps them moving forward. This creates the illusion of weightlessness.
No, gravity is a natural force that cannot be turned off or stopped. However, its effects can be reduced by traveling to areas with less gravitational pull, such as outer space or the moon.
