which AI automated machines technology can be used on big ships in ocean to let them travel at a speed of light like supersonic speed , no matter how much mass it have alternatives to/including supercavitation and laser propulsion

Traveling at the speed of light, or even at supersonic speeds, is currently beyond the realm of possibility for large ships on Earth's oceans due to the limitations of physics. The speed of light is approximately 299,792,458 meters per second, which is significantly faster than any technology we currently possess.

Supercavitation: Supercavitation is a technology that allows objects to travel through water inside a cavitation bubble, reducing hydrodynamic drag and increasing speed. However, it has its limitations and is mainly used in torpedo and military applications.

Laser Propulsion: Laser propulsion systems use directed energy from lasers to propel spacecraft. These systems can provide high speeds in the vacuum of space, but they are not suitable for underwater propulsion due to the absorption and scattering of laser light in water.

For large ships on Earth's oceans, other forms of propulsion are used, such as:

1. Conventional Propellers: Most large ships rely on conventional propellers that are driven by engines, either diesel or gas turbine, and they move through water by generating thrust.

2. Water Jets: Some high-speed vessels, such as ferries and patrol boats, use water jet propulsion, which expels water at high velocity to generate forward thrust.

3. Nuclear Propulsion: Nuclear-powered ships, like aircraft carriers and submarines, use nuclear reactors to heat water and produce steam for propulsion.

4. Wind Propulsion: Sailing ships use wind energy to move. Modern sail-assist technologies and computer systems can optimize the use of wind power.

While traveling at the speed of light or at supersonic speeds underwater is currently impossible due to the limitations of physics and the properties of water, advancements in propulsion technologies are being made for various purposes, including improving fuel efficiency and speed. However, these technologies are still constrained by the principles of fluid dynamics and the resistance of water.

For ultra-fast travel, such as supersonic and hypersonic speeds, it is more practical to consider aerospace technologies designed for flight in the atmosphere and space, where the limitations of water and the underwater environment do not apply. These technologies include scramjet engines and reusable spacecraft designed for rapid travel in air and space.

 There is no known AI automated machines technology that can be used on big ships in ocean to let them travel at a speed of light like supersonic speed, no matter how much mass it have.

The speed of light is the fastest speed at which anything can travel in the universe. It is equal to 299,792,458 meters per second. Supersonic speed is any speed greater than the speed of sound in air, which is about 343 meters per second.

The speed of a ship is limited by a number of factors, including the resistance of the water, the power of the engines, and the mass of the ship. The resistance of the water increases with speed, so it takes more and more power to propel a ship faster. The mass of the ship also affects its speed, as more mass requires more power to accelerate.

Even if we could overcome all of these challenges, there is still no known way to travel at the speed of light. The laws of physics prevent us from traveling faster than the speed of light.

However, there are a number of emerging technologies that could potentially help to increase the speed of ships. For example, one technology that is being developed is called supercavitation. Supercavitation is a phenomenon in which a fluid forms a bubble around an object, reducing the drag on the object. This could potentially allow ships to travel much faster than they currently can.

Another technology that could potentially help to increase the speed of ships is called laser propulsion. Laser propulsion uses lasers to heat and propel a plasma, which can be used to generate thrust. This technology is still in its early stages of development, but it has the potential to revolutionize ship travel.

While it is not currently possible to travel at the speed of light, emerging technologies such as supercavitation and laser propulsion could potentially allow ships to travel much faster than they currently can.
