Whats the point of anti-gravity

[Denton]

I don't understand the reasoning behind trying to discover anti-gravity. Attach a rocket to a load and make it accelerate at 9.8 m/s^2 and youve got an "anti-gravity" vehicle. It defies gravity as if it didn't exist.

So reasoning says, what would be the use of anti-gravity if it did exist and or what properties would even make it remotely useful? It would have to still use the same amount of energy to make an object escape a gravitational well as conventional methods do otherwise it would be against conservation of energy.

EDIT: Sorry I thought this was General Physics, not General Math, someone please move the thread.

This is not a math question. I am going to move it to the general physics section.

It is a question of "force". You have to apply a lot of force to overcome the weight of an object- especially a very heavy object- and that is expensive. An "anti-gravity device" or even a "gravity shield", if such a thing were possible, would eliminate the weight immediately, supposedly without the application of enormous forces. Without gravity there would be NO "gravitational well" and so it would NOT take "the same amount of energy to make an object escape a gravitational well". Yes, that would violate "conservation of energy". That's the point!

The concept of anti-gravity is still largely theoretical and has not been proven to exist. However, scientists and researchers continue to explore the idea because it could potentially have many practical applications. For example, if anti-gravity were to exist, it could revolutionize transportation by allowing objects to levitate and move without the need for traditional methods such as rockets or wheels. This could greatly reduce energy consumption and make space travel more feasible.

Additionally, anti-gravity could have implications for space exploration and research. It could potentially make it easier to launch and maneuver spacecraft, as well as allow for the creation of artificial gravity in space habitats. It could also have uses in various industries, such as manufacturing and construction, where the ability to manipulate gravity could greatly enhance efficiency and productivity.

While it is true that anti-gravity would still require energy to overcome the effects of gravity, the potential benefits and applications of this technology make it a worthwhile area of study. It is important for us to continue to push the boundaries of science and explore new possibilities, even if they may seem far-fetched at first. Who knows what advancements and innovations we may discover along the way.
