Future of Controlling Gravity

More than a century ago, humanity learned how to control electromagnetic energy and manipulate it to our liking. This has completely changed human civilization. If you think about it, many of the devices around us. And many of the technologies that we use regularly work using this electromagnetic force. You are able to read this article I am posting because of the internet. Most of the time, you are using mobile internet or Wi-Fi for this. Both of these work using electromagnetic waves.

If you think about it further, many of the wireless and wired communication devices we use today work using these electromagnetic waves. Not only that, you can hear what I'm saying through a speaker or headphones. All of this is possible because humans have been able to control electromagnetic energy. Similarly, if you have any equipment in your home or office that is powered by an electric motor, that equipment also works using electromagnetic force.
We generate electricity in various ways. In many of these ways, a dynamo is used for that. So this dynamo is able to generate electricity because of electromagnetic force. So if you think about it further, we have been able to create many of the electrical devices and technological devices around us because humans have been able to control this electromagnetic force and manipulate it as we need. Because of this, human civilization has completely changed by now, and we all know that there are four fundamental forces in this universe. They are strong nuclear interaction, weak nuclear interaction, electromagnetism, and gravity.

So, just as we were able to control this electromagnetic force as we wanted, if one day we were able to control gravity as well, how would that change our lives? As we currently understand, gravity is caused by mass in space-time. That is, by a curvature in space-time. At first glance, it seems to us that small objects are attracted to large objects. But this gravity is a very mysterious force.
If we go down to the quantum level and look at very small particles, we won't be able to see any gravitational force acting between them. But the larger objects that come together from these small particles do have gravitational force. And as this object gets bigger, its gravitational force also increases. So if you go beyond here and look at galaxies and clusters like that, this gravitational force becomes even stronger. So we have had to use imaginary things like dark matter to explain this.

So from all this, we have been able to understand that our knowledge about this force of gravity is very limited. So scientists are working very hard to understand what this force of gravity is and how it works. So to control this gravitational force, we need objects with negative mass. We know that normal mass causes a curvature in space-time.
If there is an object with this negative mass, then it will also cause a curvature in space-time. But on the contrary, our knowledge of these negative masses is very limited. Scientists are still working hard to figure out whether these negative masses really exist, and if they do, how do we collect them? Or even create them?
Even if we somehow learn to create these negative masses one day, the task won't be that easy, because if we wanted to completely cancel out the gravitational field generated by this Earth, we would need a negative mass that is as big as the Earth, with the same mass as the Earth. So you can imagine how serious this is. But instead, if we could build a gravity field generator, using that device, we would be able to control this gravitational field, and also create new gravitational fields as we want.

If we could somehow control this gravitational field, human civilization and the technologies we use could be completely different. So we could build airplanes that don't use jet engines or propellers. And they will be able to move very quietly, very safely, and carry very high loads of their own. And when we build roads, we won't always have to build them parallel to the ground. We will be able to control this gravitational field and build roads the way we want.

We usually use a staircase to move to an upper floor of a tall building. But if we could control the gravitational field, that is, if we could turn the gravitational field outside that building by 90 degrees, then we could walk along the outside wall of this building and climb it.
We always use rockets for space travel. These rockets are not that good of a technology because they use a controlled explosion. But if we can somehow control the gravitational field, we will be able to travel throughout space with rockets that operate very quietly, efficiently, and safely.
