# Speed of Sound, Light, and Time?

• soryy708
In summary, the speed of sound and the speed of light are both relative to each-other, and time has no speed.

Hi.

I apologize if this thread is in the wrong location, as you see: My knowladge of Physics is (probably) at the level of a 10th grader... or maybe less... which is what I am.

I won't bore you with how I got into such a theory, but before I start I'd like to state that I start this topic for the sake of looking at the subject from diffrent, more proffesional angles, and perhapes proove it wrong.

The theory of relativity states that everything is relative to each-other (or atleast that's how I was told). So, diffrent speeds are relative to each-other.
Quite a long time ago, there was a theory that there is no way to cross the Speed of Sound. But it was done, and infact now it's an every-day deal.
Now it's said that there is no way to cross the speed of light - but how is that diffrent from the speed of sound?
Also, what about Time? Does it have speed? Is it possible to go faster than time itself?
And if it is, what happens? Something in me tells me either Teleportation, either travel backwards in time.
Speaking of which, I've read that gravity distorts time passage - Is it possible to create a massive object, which will distort time so much that it stops? Or, even go backwards?
Is it possible to move time? What if time is not a line, but has actually two dimensions? Maybe it has three? Is time is actually a circle?

So many questions, so little knowladge. I'll cut this short here.

-- Thanks in advance, I'm looking forward for either having myself shouted at with useless, shallow skeptism and having that topic moved / deleted. Either developing a healthy conversation, resulting in perhapes a new scientific discovery (I'm an optimist, I'll go with the second).

Edit: Seems like "Cosmology" fits it better.

Hi soryy, welcome to the forum.

Before I made my first post here, I read every thread and post I could for a year in order to learn as much as I could about relativity. I really think that is what you should do. You can find lots of answers to your questions and even some answers to questions you never thought to ask. The purpose of this forum is to help people like you understand relativity.

I notice that you have a tendency to provide hopeful answers to some of your questions. If we just went through your questions and answered them yes or no with no explanation, would that satisfy you? I doubt it. You're hoping that a new scientific discovery will happen as a result of your conversations. Trust me, that's not going to happen. If you really want to understand these things, you can spend a lot of your time learning just by diving into the various threads and read what they have to say.

## What is the speed of sound?

The speed of sound is the distance that sound waves travel in a given amount of time. In dry air at 20 degrees Celsius, the speed of sound is approximately 343 meters per second. This can vary depending on factors such as temperature, humidity, and altitude.

## How does the speed of sound compare to the speed of light?

The speed of sound is significantly slower than the speed of light. While sound travels at around 343 meters per second, light travels at approximately 299,792,458 meters per second in a vacuum. This means light travels about 874,030 times faster than sound.

## What factors affect the speed of sound?

The speed of sound can be affected by factors such as temperature, humidity, altitude, and the medium through which it is traveling. Sound waves travel faster in warmer temperatures, higher humidity, and denser mediums, such as water or solids.

## What is the relationship between speed of sound and time?

The speed of sound and time are directly related. As the speed of sound increases, the time it takes for sound waves to travel a certain distance decreases. This means that the faster the speed of sound, the shorter the time it takes for sound to travel.

## How is the speed of light measured?

The speed of light is measured using a variety of techniques, including using lasers, satellites, and the properties of certain materials. One common method is using the time it takes for light to travel a known distance, such as the distance between two mirrors, and using the equation speed = distance/time to calculate the speed of light.
