Can it be curvature driven now, can it really reach the speed of light?

Until now, speed is still the unremitting pursuit of human beings, but until now, even the Parker probe who went to the inner planet or even the sun to explore the speed is still hovering around 200km s! And reaching the nearest Proxima Centauri is more than 4 light-years away, and even at this speed, it will take more than 6,000 years to reach Proxima Centauri! Of course, this speed is not the extreme speed of the rocket, after all, the rocket still has a very large potential to be explored, with the advancement of ion propulsion technology, and even the breakthrough of nuclear fusion engines in the future, ours.

The speed can still be improved in a higher direction! But I don't know if you have noticed that no matter how hard we try, there will always be a ceiling blocking our steps, and this is the speed of light! Because under the condition that the speed is close to the speed of light, its qualitative increase effect will make it impossible to make the aircraft faster no matter how much thrust is increased, even if it is 1m s, because the mass increase effect has canceled out the power provided by the rocket's thrust reverser!

1. Warp engine

The principle of this engine uses the elasticity of space to propel the spaceship forward, because space expansion is not limited by the speed of light, but there is also a requirement, that is, the curvature engine in "The Three-Body Problem" and the warp engine in "Star Trek", although the principle is the same, but the effect is completely different, because the upper limit of the curvature engine is the speed of light, but the warp engine has almost no upper limit!

2. Wormholes

The wormhole near Saturn in "Interstellar" is the key to connecting the plot of the whole movie, of course, this is not an engine, but a kind of connection of distant space in the form of an Einstein-Rosen bridge, and the aircraft entering this tunnel can use ordinary engines, but do not need to go through the actual distance in three-dimensional space, but directly through the tunnel to the distant universe!

I think it can reach the speed of light, but it takes a certain amount of time and a certain level of research by relevant scientists.

The speed of light, the current technology is impossible, but it can be infinitely close to the speed of light, that is, to use the power of nuclear bombs ** to propel the spacecraft, the easiest way is to keep throwing nuclear bombs at the back of the spacecraft, the American Orion program is ready to do this, but it is too dangerous, so it is abandoned.

It can't be curvature driven now, but it may be possible in the future, not to reach the speed of light.

It's impossible, but I think the future is achievable.

How terrible is curvature drive? Once humans have mastered curvature drive, they will be able to fly faster than the speed of light.

I guess it's enough to choke, after all, the speed of light can't be captured by us humans, isn't it?

I think it's very difficult, it's impossible to reach the speed of light.

Because under the condition that the speed is close to the speed of light, its qualitative increase effect will make it impossible to make the aircraft faster no matter how much thrust is increased, even if it is 1m s

I think there is still a great possibility, depending on the situation.

The speed of light is really, really fast, and it may take some time to get to that point.

It is possible to create an engine that can shrink the space in front and expand the space behind, and propel the ship forward with the "transformation" of space.

To understand how spatial curvature (or warp speed) drives, imagine a scenario where you and a cat sit at opposite ends of a carpet and the cat runs towards you at velocity c (which is the highest speed it can run on the carpet), and you pull the carpet at speed z and pull the carpet and the cat running on the carpet to you. When pulling the carpet, the cat's speed relative to you is c+z - more than c, but the cat moves with the carpet under the cat's feet, and it does not exceed its speed limit in that area.

In 1994, physicist Miguel Alcubierre proposed that space could be stretched by waves, so that the space in front of the spacecraft would shrink and the space behind it would expand, and the spacecraft would "ride" the "waves" of space in space.

This "wave" interval is called a "warp bubble", and inside it is a flat space-time. The spacecraft is not really moving in the bubble, but is carried away by the bubble, which does not violate the "fastest speed of light" limit in physics. The speed of warp is not faster than light for space, but for us it is faster than light.

How terrible is curvature drive? Once humans have mastered curvature drive, they will be able to fly faster than the speed of light.

Curvature driven:

Refers to changing the characteristics of the spacecraft around the spacecraft to become an inverse force field.

For example, when space near the sun is curved, time passes slower relative to the earth's periphery, and the longer life of particles on the earth is actually the decay of particles.

Then curvature drive is the opposite.

If the spacecraft can reach half the speed of light without curvature drive, then if the curvature drive is turned on, for example, if the speed of time flow is 10 times that of the Earth, then the spacecraft can reach 5 times the speed of light (measured from the Earth) and travel at half the speed of light when measured inside the spacecraft.

However, in the curvature-driven era, the ship's non-curvature ship will be as close to the speed of light as possible to ensure the life of the crew.

How scary is the curvature drive? Once humans have mastered the curvature drive, He Chen will be able to fly faster than the speed of light.
