Will we be able to defy gravity sometime in the future? Like, 1000 years from now?
olivermsun said:We sure can, but I'm not sure gravity cares.

Gravity is defined as the force that pulls objects towards each other. It is a fundamental force of nature and is responsible for keeping planets in orbit and objects on Earth from floating away.
Technically, no, we cannot defy gravity. It is a natural force that cannot be turned off or defied. However, we can overcome its effects by using other forces, such as lift or propulsion, to counteract the pull of gravity.
No, it is not possible for humans to fly without the use of technology or external forces. While some animals, such as birds and insects, are able to fly due to their physical characteristics and abilities, humans do not possess the natural ability to fly.
In space, astronauts appear to be floating because they are in a state of freefall. This means that they are constantly falling towards Earth, but their horizontal velocity keeps them moving forward, creating the illusion of weightlessness.
Currently, our understanding of gravity is limited and there is still much to learn about this force. While we have been able to manipulate and harness its effects, completely understanding and controlling gravity may not be possible for humans in the near future.
