1. • • As gravity tries to pull you down, the atoms in the chair push back upward—you can't squash atoms that easily—and counteract with what is essentially an electromagnetic force. When someone stands on the floor and goes nowhere, the ground is effectively pushing back up again and saying "I will not be squashed."

   Why do scientists want to remove the effects of gravity?

   • That’s what NASA researchers aim to find out. Removing the effects of gravity can enable researchers to answer important scientific questions and study how humans can safely stay longer in space. For example, the shape of flames on Earth is formed by heated, less dense air rising, which is due to gravity. In space, flames burn as spheres.

   Can a 'impossible drive' counteract Earth's gravity?

   • While the company behind the drive, Exodus Propulsion Technologies, says that the drive can achieve a thrust to counteract Earth’s gravity, such a claim still needs independent verification and a healthy dose of skepticism. In 2001, British Electrical Engineer Roger Shawyer first introduced the “impossible drive,” known as the EmDrive.

   How does gravity affect our lives?

   • All aspects of our lives are affected by gravity. Muscles develop to push against the force of gravity. Sports rely on balls being pulled back to Earth. Cyclists fight against it to climb mountains. What if we didn’t have to contend with gravity? And what can we learn by studying phenomena unencumbered by it?

   Why is gravitational force important?

   • Gravity is the force that causes attraction between masses. It’s why when you drop a pen, it falls to the ground. But because gravitational force is proportional to the mass of the object, only large objects like planets create tangible attractions. This is why the study of gravity traditionally focused on massive objects like planets.

   How can astronauts overcome the absence of gravity?

   • The current best method to overcome the absence of gravity is to increase load on the cells in another way – via exercise. Astronauts typically spend at least to maintain healthy blood volume and reduce bone and muscle loss. Unfortunately, rigorous exercises can only slow down the deterioration of the astronauts’ health, not prevent it completely.

   What if gravity wasn't in space?

   • Gravity is a force that exudes from mass, which, I’m sure, can be found everywhere in the Universe. Its pull might approach zero, but never reach it. It cannot be escaped. If gravity was nonexistent in space, the moon, some 4,00,000 km away, wouldn’t revolve around us constantly. (Photo Credit: NASA)

   May 15, 2023 · Weighing machines determine an object’s mass by calculating this normal force and dividing it by Earth’s acceleration due to gravity. This is achieved by a nimble calibration. However, if the ISS is falling towards the Earth, why doesn’t it crash into it? What causes it to orbit the planet instead?
