Is comunication faster that light possible: yes( maybe )

In summary, the conversation discusses the possibility of communication faster than the speed of light by using a big stick between Earth and the sun. It is argued that this is not possible due to the electromagnetic forces holding the stick together. A source is provided for further reading on the topic.

i think it is possible but its too complicated to write down in english so i think comunication faster than light is possible without anything acctualy moving faster than light. If you had a big stick between Earth and the sun and you push the stick towards the sun for 1 inch it will instantly move at the other side too. for light to come from sun it takes 7 min and for this to move at the other side after you push it on your side nothing.look at the image so you can get a better understanding.

No. You're not taking into account the electromagnetic forces that hold the stick together. The other end won't move faster than the speed of light.

What is faster than light communication?

Faster than light communication refers to the transmission of information or signals at a speed greater than the speed of light in a vacuum, which is approximately 299,792,458 meters per second.

Is faster than light communication possible?

Currently, there is no scientific evidence to support the possibility of faster than light communication. According to Einstein's theory of relativity, the speed of light is the maximum speed at which any object or information can travel in the universe.

What is quantum entanglement?

Quantum entanglement is a phenomenon in quantum mechanics where two particles become connected in such a way that any change in one particle will affect the other, regardless of the distance between them. This has been proposed as a potential way for faster than light communication, but it has not been proven to be possible.

What are the limitations of faster than light communication?

Aside from the lack of scientific evidence, there are several theoretical limitations to faster than light communication. These include the energy required to achieve such speeds, the distortion of time and space, and potential violations of causality, which is the principle that an effect cannot occur before its cause.

Are there any proposed methods for faster than light communication?

Some scientists have proposed theoretical methods for faster than light communication, such as using wormholes or manipulating space-time. However, these ideas are still purely theoretical and have not been proven to be feasible. The current understanding of physics suggests that faster than light communication is not possible.
