On March 5, 2025, the weather in early spring was unpredictable, and there was light snow in Xiong'an New Area today.

Zhou Yu stood in front of the office window, looking at the snow outside.

He heard footsteps outside the office, retracted his thoughts, and looked at the office door.

Li Qihua, the director of the Gravity Lab, walked into the office with an intelligent robot.

The intelligent robot behind Li Qihua is holding a round ball the size of a football with a very smooth surface with both arms.

The robotic arm of the intelligent robot is slightly bent downward, and the robotic arm appears stiff, and the weight of this ball should not be light.

When Li Qihua came to the office, he couldn't hide the excited look on his face, and immediately reported to Zhou Yu: "Mr. Zhou, we summarized the gravitational data detected by the space physics laboratory equipment and discovered the characteristics of the planet's gravity.

According to the situation of the earth's gravity, a gravitational force with the same properties as the earth's gravity has been created in the opposite direction.

Using this force generated by the device, we can achieve anti-gravity technology that levitates objects on the surface of the earth. ”

Zhou Yu immediately walked quickly in front of Li Qihua, holding the table with his hand, and observed the ball carried by the intelligent robot.

He asked in surprise: "The anti-gravity device has been manufactured, how effective is it, and how many tons of objects can this anti-gravity technology carry."

Li Qihua knew that Zhou Yu was really concerned, so he showed such an anxious look, and he didn't make a fool of himself, and immediately introduced Zhou Yu to the situation of the anti-gravity equipment.

He pointed to the ball in the hand of the intelligent robot and said, "Mr. Zhou, this is the core component of the anti-gravity equipment, which can generate forces with the same gravitational properties as the earth and in the opposite direction.

This force has the same properties as the Earth's gravitational pull, which means that these two forces can interact with each other to produce action and reaction forces.

According to Newton's third law, the action force is equal to the reaction force.

As long as the limit of the equipment is not reached, the anti-gravity technology can be realized within its weight limit. ”

While Li Qihua spoke, his right hand was a little on the ball dragged by the intelligent robot.

The ball began to spin, and the robot removed his arms from the ball, which remained spinning in place.

Li Qihua began to move the ball with his hand, pushing it as if pushing a very light object.

After a slight movement, it moves forward due to inertia and quickly stops due to air resistance.

Zhou Yu looked at the performance of this round ball, and he said the question in his heart: "Director Li, can't the anti-gravity device act with the help of gravity?" What is its load limit? ”

Li Qihua immediately replied: "Mr. Zhou, anti-gravity only relies on the relationship between action and reaction force, and the equipment only maintains anti-gravity, making it look like a weightless object in space."

In order to make this object move, a certain external force must be applied.

Without the interference of the Earth's gravity, after the anti-gravity technology is activated, a child can lift tens of thousands of tons of things.

There is no change in the mass and corresponding physical properties of this object, it only cancels out the gravitational pull of the Earth on it.

If you do not take into account the energy supply, the state that the anti-gravity device can now carry the limit mass is 600,000 tons.

This data is precisely calculated, and the mass of the earth is 5.965×10^24kg, which is 60 trillion tons.

The difference between the mass of the object and the Earth must be large to ensure that the object has no effect on the Earth after the anti-gravity force is activated.

Once an object exceeds 600,000 tons, it has an impact on the Earth's rotation, and for every 600,000 tons of an object, the effect of the impact increases exponentially.

There will definitely be more than one anti-gravity device on Earth in the future, and we want to ensure that anti-gravity technology will not affect the Earth.

It can only be limited to 500,000 tons, which is actually an idealized calculation, and in reality it is impossible to achieve this goal.

Of course, the greater the mass of the object, the more energy is required to activate the anti-gravity device, and the energy increases exponentially as the mass increases.

This technology still pursues the law of conservation of mass and energy, and if you want to suspend 500,000 tons of objects in the air, the current nuclear power energy is simply not feasible.

Even powering 10,000 large nuclear power plants will not be able to provide huge consumption, unless we find more efficient energy sources later. ”

"The theoretical load is 600,000 tons, and the actual load is 60,000 tons. That's a huge amount of data, and you're not satisfied.

Our mass projectors, now only capable of launching objects of 100 tons into space.

Even if anti-gravity technology can send 1,000 tons of objects into space, it is extremely advanced technology. Zhou Yu said excitedly.

He was so happy to hear the load capacity of this technology, and his two front teeth were exposed.

Zhou Yu was puzzled, scientists are not satisfied with the load capacity of anti-gravity technology, do they want to send 600,000 tons of objects into space.

It's impossible to think about it, the energy is growing exponentially, this energy consumption is too terrible, it is better to transport it in batches.

Zhou Yu praised: "The ultimate load of anti-gravity technology is already a very good mode of transportation for space exploration.

With the successful development of anti-gravity equipment, we can all build space cities in the future, rather than just building a space station.

The space cities that appear in science fiction movies will appear in reality. ”

Li Qihua shook his head slightly and denied: "Mr. Zhou, what you think is too good, the limit of anti-gravity technology can carry a mass of 500,000 tons."

As I said earlier, it takes a lot of energy and is not worth it.

The energy consumption of anti-gravity equipment to carry items shows an exponential growth relationship with the quality of goods.

Now we weigh the weight and power storage capacity of the particle battery, and the ultimate load of anti-gravity technology is 500 tons, and the low-energy load is 2 tons.

Anti-gravity equipment can be loaded from 2 tons to 500 tons.

Below 2 tons, the anti-gravity equipment cannot ensure a stable balance, and above 500 tons, the energy consumption of the anti-gravity equipment cannot be satisfied with particle batteries.

Anti-gravity equipment has a lot of potential, but our current technology can't give full play to its powerful capabilities. ”

"The load capacity of 500 tons is also very good, it can completely replace the mass projector. The company's technology is developing so fast that the quality projector that cost a lot of money to build is now a chicken rib. Zhou Yu said with emotion.

"Mr. Zhou, the mass projector has not become a chicken rib, it can still play a powerful effect.

We have just developed an anti-gravity device and it has a lot of potential, but we are limited by our technology and cannot realize its full potential.

In order to maintain the balance of gravity, the anti-gravity device has a maximum speed of only 10 meters per second.

It climbs into space, and it's an extremely slow process.

It is okay to use anti-gravity equipment to transport people, animals and some special items, it is convenient and fast to transport a large number of items, or it is more convenient to use mass projectors. ”

Li Qihua immediately explained to Zhou Yu the advantages and disadvantages of anti-gravity technology and mass projectors.

"It's great that they can do their job. Keep up your efforts to get anti-gravity equipment into service as soon as possible. Zhou Yu said with satisfaction.

He was surprised a lot by the anti-gravity device, which was a device with a high upper and lower limits.
