Metropolis:Technology Maniacs

Although it is impossible to accelerate faster than the speed of light directly, some ingenious means can be used to bypass the limitation of relativity, so as to achieve the purpose of exceeding the speed of light.

That's how the curvature engine was created, and it's also a device to fly faster than light.

A spaceship with a curvature engine can travel faster than light in space.

Although this seems to violate relativity, it is a technology that can be implemented.

In fact, the curvature engine does not violate the theory of relativity, because it is achieved by means of side effect.

Curvature engine may sound very tall, but the truth is very simple.

The space of the whole universe is not flat, but full of all kinds of folds. The size of these folds is curvature.

When the curvature is zero, the space is completely flat, and the greater the curvature, the bigger the wrinkles.

Curvature engine is a kind of technology that uses space folds to drive spacecraft.

If we can change the curvature of space, we can increase the wrinkles in the space, which is equivalent to shortening the distance between two points.

Draw two points on a piece of white paper. The nearest distance is not a straight line between the two points. Instead, fold the white paper directly and let the two points touch each other directly.

Although curvature engine can not make two points coincide, it can greatly shorten the distance between two points.

So the curvature engine is not really beyond the speed of light, but it folds up the space and shortens the distance in the middle.

To put it bluntly, the curvature engine does not increase the speed of the spacecraft, but shortens the space in which the spacecraft is located.

If a spaceship needs to reach a light-year away, but its speed is only half the speed of light, it will take two years to reach its destination.

But when the spacecraft started its curvature engine, the wrinkles in space quadrupled.

Originally, a light-year journey for a spaceship has become a quarter of a light-year distance.

In this way, it only takes half a year for the spacecraft to reach its destination a light year away.

All in all, the spacecraft's speed exceeds the speed of light, reaching twice the speed of light.

In fact, it's not that the speed of the spaceship is getting faster, it's still half the speed of light, but the distance is shortened to one fourth of the original, which makes the overall speed four times faster.

The curvature engine actually shortens the distance in space so that the spacecraft can travel faster than light.

The curvature engine is a device that increases the space wrinkle by changing the curvature, and finally increases the speed of the spacecraft.

So the curvature engine doesn't violate relativity, it just bypasses the limitations of relativity.

Of course, curvature engines can do more than that. Quadrupling the speed is not the limit of curvature engines.

The better the curvature of the engine, the bigger the space wrinkles will be, and the more speed the spacecraft will eventually increase.

Super civilizations that can span the entire universe have very advanced curvature engines.

Their curvature engines can increase the speed of tens of thousands of times, making it easy for spaceships to reach the speed of light thousands of times.

However, Yesu can't make such an advanced curvature engine. It's something that the most top-level cosmic civilization can play with. The curvature engine Yesu wants to build is not so advanced.

The curvature engine that Ye Su plans to study this time can shorten the space by 20 times, that is to say, it can increase the speed of spacecraft by 20 times.

In the design, Yeosu's spaceship is half the speed of light.

So with this curvature engine installed, the speed can reach ten times the speed of light.

Ten times the speed of light is enough for the time being, at least in the solar system.

By then, it will take only a few minutes for Mars to reach the earth, which is almost as fast as eating at a snack stand at the gate.

Ten times the speed of light is enough for the galaxies near yessou, such as the nearest neighbor star in the solar system, which is only about five light-years away.

The distance is ten times the speed of light and can be reached in half a year.

That is to say, Yesu sent a spaceship to be near star, and it will arrive in half a year.

However, a spaceship with the speed of 10 times the speed of light will take a long time to go to places thousands of light years away.

But by the time it takes to go that far away, Yesu may have a better curvature engine.

We just need to develop a better curvature engine behind Yeosu to increase the speed of the spacecraft once again.

So curvature engine is the most important technology of interstellar civilization, which is related to the problem of flight speed.If you want to increase the speed of the spaceship, only the curvature engine is the way. There is no room for the speed of the spacecraft itself to improve.

Basically, the speed of spaceships of all civilizations is about half the speed of light.

It's not that the speed can't be increased, it's just that when the speed exceeds half of the speed of light, it takes too much energy to accelerate.

The faster the speed, the more energy it takes to accelerate, which is a fundamental law of the universe that cannot be bypassed.

Accelerating to half the speed of light is the most energy efficient option, and spaceships are basically designed like this.

So what limits the speed of a civilized spaceship is the curvature engine technology.

When ye Su decided to develop the curvature engine first, she immediately went to work.

However, between the development of curvature engine, Ye Su still needs a lot of manufacturing materials.

Curvature engine needs a lot of materials, many of which are rare materials.

One of the rarest materials is platinum, which requires a lot of platinum to make curvature engines.

This is the real purpose of Yesu's exploration of platinum on Mars, and it is also the material Yesu needs most now.

The biggest use of platinum is to make curvature engines, which are in great demand even for high-end cosmic civilization.

That's why Yeosu will lay out on Mars ahead of time, mining platinum on a large scale.
