What is Anti Gravity?
From the word "Anti" it literally means the act of creating a place or field that neutralizes the effect of gravity. This implies that anti gravity is non gravitational force or field. They don't allow gravity to occur because they oppose gravity.
From the studies of science and physics, the existence of gravity was experimented by various physicist such as Galeleo who stated that if a stone and a feather were dropped at the same time with the absent of air resistance and Friction, both of them will surely fall at the same time. The main reason this is possible is due to the existence of gravity.
Another great physicist who added more to the existence of gravity is Isaac Newton. It was said that Isaac Newton sat under a tree when an orange or apple (can't remember which) fell on him which made him more curious about how such thing could occur. He was able to predict that there was a force pulling the mass of the orange with the help of gravity which we all know as weight. This made him went through series of research and he did a lot of work on the effect of gravity in space and this brought about "Newton's Law Of Universal Gravitation".
I am sure we've all heard that anything that goes up must surely come down. They main reason why any substance comes down when we throw them up is due to the effect of gravity. Modern Technology and some researchers were able to come up with the concept of "Anti gravity" by creating some opposing gravitational field in some system which makes it anti gravitational.
I am still astonished about Nikola Tesla statement about his view towards gravity as he claims that "gravity is dead but ether lives". I don't really know how true this is but I can make more research about this.
A good example of anti gravity can be felt or observed in space. We all have seen some space researchers like NASA in different pictures or videos about how they float, fly and even walk in space despite there is no gravity in space. The main reason for this is that the space costume used by astronauts usually provides gravity for them in space. This means that without that space costume, they won't be able to walk freely in space. If you jump in space, you are already gone because you will be flying like superman 😁😁😂😀.
In conclusion, Anti gravity is mostly created to remove the effects of gravity. It makes such field or space to be non gravitational. A good effect of non gravitational field can be observed in space. Modern technology is also working on developing anti gravitational systems which can make life more easier for man. Example is that car will be able to float on water with the help of anti gravity system.
Thanks for reading and I hope this helps.
