The statement that there is no gravity in space is not true. Gravity exists everywhere in space, although its strength decreases with distance from massive objects. For example, astronauts aboard the International Space Station experience microgravity because they are in a state of free fall, orbiting Earth, rather than being completely devoid of gravitational influence. Thus, while gravity is weaker in far-off regions of space, it is always present.

The most difficult part of the space cushion to control is often the rear space, as it involves managing the distance between your vehicle and the vehicles behind you. This area can be unpredictable due to the actions of following drivers, such as sudden acceleration or braking. Additionally, maintaining a safe distance can be challenging in heavy traffic or when being tailgated. It's essential to remain vigilant and adjust your speed or position as needed to ensure safety.

A space entirely devoid of matter is known as a vacuum. In such a vacuum, there are no particles, atoms, or molecules, meaning it lacks any physical substance. While perfect vacuums are theoretical and hard to achieve, even the best approximations still contain some residual particles and energy fluctuations. This concept is crucial in fields like physics and astronomy, as it helps scientists understand the behavior of light, radiation, and fundamental forces in the absence of matter.
