Can we travel over light speed?

In summary, the conversation discusses the concept of particles traveling at speeds faster than light, including tachyons and luxons. The conversation also mentions the possibility of using wormholes for travel, but notes that there is no evidence for their existence. In addition, it is mentioned that traveling at the speed of light is impossible due to the requirement of infinite energy. The conversation also references a post for definitions of terms. However, the conversation is from an old thread and it is noted that wormholes may not actually exist.

Okay, here's an old answer: NO.

You may need some brief background: Einstein says nothing with rest mass can travel to a speed of ≥c. There are tachyons, with an imaginary rest mass, and travel natually faster than light, and particles with no rest mass travel at exactly the speed of light. Tachyons have not been observed, only thought of. Luxons are what we know and love, they travel at less than the speed of light

ooops, I'm really sorry, I mixed some things up. Photons are luxons and tardyons are particles that travel slower than light, tachyons travel faster, In short

Luxons have zero proper/rest mass, tardyons have positive, and tachyons have an imaginary number as proper/rest mass

its impossible to travel at the speed of c because of something about requiring infinite energy.(i remember from the science channal) But we could use wormholes, if we learn how

This is a four-and-a-half year old thread.

Furthermore, wormholes may not exist. There is certainly no evidence for them.

1. Can we really travel faster than the speed of light?

Based on our current understanding of physics, it is not possible for any object with mass to travel at the speed of light, let alone faster. This is due to the laws of relativity, which state that as an object approaches the speed of light, its mass approaches infinity and would require an infinite amount of energy to continue accelerating.

2. What is the speed of light and why is it considered the fastest speed possible?

The speed of light is approximately 299,792,458 meters per second, or 670,616,629 miles per hour. It is considered the fastest speed possible because it is the speed at which all electromagnetic radiation (including light) travels in a vacuum. According to Einstein's theory of relativity, nothing can travel faster than the speed of light.

3. Is there any way to bypass the speed of light limit?

As of now, there is no known way to bypass the speed of light limit. Some theories suggest that it may be possible through methods such as wormholes or warping space-time, but these are purely theoretical and have not been proven to be possible.

4. Why is traveling faster than the speed of light considered impossible?

As mentioned earlier, it is considered impossible due to the laws of relativity. The closer an object gets to the speed of light, the higher its mass becomes and the more energy is required to continue accelerating. Ultimately, it would require an infinite amount of energy to reach the speed of light, making it impossible.

5. What are the potential consequences of traveling faster than the speed of light?

The potential consequences are not fully understood, as we do not have the technology or means to achieve such speeds. However, some theories suggest that it could result in time dilation, where time passes differently for the traveler compared to those who are not traveling at such high speeds. It could also have a significant impact on the laws of physics as we know them.
