Faster than the speed of light

In summary: The conversation discusses the concept of time dilation due to speed and the effects on aging. The example given is of a spaceship traveling faster than the speed of light from Earth to another planet and back in 1 year, with the trip to the other planet taking 3 months and the return also taking 3 months. The question is posed if the spaceship's crew would have aged 1 year and 6 months, the same as those on Earth. In summary, the concept of time dilation due to speed is explained and it is stated that the crew would only age 1 year due to the trip being just shy of the speed of light. The conversation also addresses the need for further study in physics and the importance of specifying the mass of the other

Time passes faster further from the center of gravity of a large mass (like the Earth). For example, if a spaceship travels faster than the speed of light from Earth to another planet and after 1 year returns to Earth. From Earth to the other planet takes 3 months and return 3 months.

Would the spaceships crew have also aged 1 year 6 months, same as we on Earth?

This phrase alone tells me you don't know what you're talking about.

Aside from the impossibility of traveling at the speed of light, let alone faster, if the spaceship traveled at just a hair under the speed of light, the spaceship's crew will have aged just 1 year, the year they spent on the other planet. They will not age hardly at all during their high-speed trip going to or coming back from the planet.

By the way, this has nothing to do with gravity, but only with relative speed.

Astrid,

In this, as in the other posts you have made so far on this site, you are showing clearly that you have no concept of actual physics. Why do you think it will be helpful to you to ask questions about ridiculous things that make no sense? Don't you think it would be more helpful to you to study some ACTUAL physics and then ask questions about that if there are part you don't understand?

As others mentioned, "if a spaceship travels faster than the speed of light" is nonsense. (How far did you get with your physics study? Are you studying something on this topic?)

There is also a logical failure in your question: as you indicate that the answer depends on it, you forgot to specify the mass of the other planet compared to that of the Earth.

Okay, I am not even familiar with any forums. I am not surprised if I post this to myself. To be honest, I don't know whether one of you can read this. Let's see what happens.

OK, enough piling on. Thread locked. In the future, it's better to report threads than to pile on the OP. And OP, please reread the PF Rules, which you agreed to when you joined.
 

What is the concept of "Faster than the speed of light"?

The concept of "Faster than the speed of light" refers to the idea of an object or information traveling at a speed faster than the speed of light, which is approximately 299,792,458 meters per second.

Is anything actually faster than the speed of light?

According to the current laws of physics, nothing can travel faster than the speed of light. The speed of light is considered to be the cosmic speed limit and has been confirmed by numerous experiments and observations.

What happens if something were to travel faster than the speed of light?

If something were to travel faster than the speed of light, it would violate the laws of physics as we know them. It would also have infinite mass and require infinite energy, making it impossible to achieve such speeds.

Are there any exceptions to the speed of light barrier?

There are certain phenomena, such as the expansion of the universe, where objects seem to be moving away from each other at speeds faster than the speed of light. However, this is not due to the actual movement of the objects, but rather the expansion of space itself.

What are the implications of faster than light travel for space exploration?

If faster than light travel were possible, it would revolutionize space exploration and allow us to reach distant galaxies and planets in a much shorter amount of time. However, until this is proven to be possible, we must continue to rely on the speed of light as our limit for traveling through space.
