Why the speed increases,speed of time decreases?

In summary, the conversation discusses the observation of time slowing down when an object is moving at the speed of light. The reason for this phenomenon is not fully understood, but it is believed that it is due to the maximum possible speed limit not being violated. The concept is compared to a coordinate plane, where traveling along multiple dimensions at once requires a slower speed in each individual dimension. It is also linked to Einstein's theory of relativity, where time appears to flow at different rates depending on an object's speed through spacetime.

why the speed increases,speed of time decreases??

yesterday i was watching a video in which a train was moving with almost speed of light but during that time the passenger in the train where moving very slow or in other words i can say the speed of time decreased...so i am not getting why the speed of time decreased?please help me by solving this doubt...

It's an observation. I don't think anyone would be able to say WHY it happens, just that it does so that the maximum possible speed allowed isn't violated.

Although this may not answer WHY, a visual I like to use is that of coordinate planes.

Time is a dimension for a reason, it is not a spatial dimension but it still follows the attributes of a dimension.

Lets say you have a simple cartesian plane on your paper. Draw straight across the X-axis at our pretend speed of light, say, 5 mm per second. Going strait across the X axis at 5 mm per second is the fastest possible way to traverse the X coordinate. While doing this, you are not traversing the Y coordinate at all.

If you draw a diagonal line, going up and to the right at 5 mm per second, you traverse both the X and Y coordinates, but it requires you to travel across X more slowly than you were you were not traveling along the Y coordinate. You also in turn travel Y more slowly than you would had you been traveling along Y alone.

Make it three-dimensional with a Z axis and you can still visualize that it is the same. You can traverse all 3 dimensions at once equally at 5mm / second, but this is the slowest possible way to travel among each dimension. You could travel among just X and Y, or Y and Z, or Z and X, without traveling along the missing dimension at all, etc. You are traveling the same speed always, 5mm/second but among each individual dimension the speed changes based on how your speed is "divided" among dimensions.

You can designate a time dimension as well in addition to these spatial dimensions. Look at it this way, if you are traveling ONLY along our time dimension (W) and not moving AT ALL (motionless relative to whatever is measuring your relative time/motion) along our X/Y/Z coordinates then this represents a "normal" flow of time. Start moving in any spatial dimension and it requires that you will be moving at less than 5 mm / second along our W time dimension.

Among our every day speeds relative to what is making measurement we are still moving almost completely along the "time" dimension and almost not at all among the spatial dimension, but rest assured ANY relative motion has an effect on the relative time flow that is measured.

This is also linked to why einstein had the idea that at relative motionless, we are moving through time at the speed of light (from our own inertial frame of reference, we are ALWAYS motionless and that's why we ALWAYS experience time flowing normally according to our own experiences). Move spacially and you are moving slower than the speed of light through time relative to what's measuring you. Move spacially at the speed of light and you cease to move through time relative to what is measuring you. The idea is that our speed through spacetime is ALWAYS at C, but what varies is what dimension we are traveling along.



That's just my way of thinking!
 

1. Why does the speed of time seem to slow down as we get older?

The perception that time is moving faster as we age is due to the way our brains process information. As we get older, our brains have already accumulated a large amount of knowledge and experiences, making it easier for them to process and recall information. This results in the feeling that time is passing by quickly because we are not forming as many new memories and experiences as we did when we were younger.

2. Why does time seem to pass by faster when we are having fun?

When we are engaged in activities that we enjoy, our brains are more focused and stimulated, making us more aware of the passing of time. This heightened state of attention can make time seem to pass by more quickly because our brains are processing more information and forming more memories than when we are engaged in mundane tasks.

3. How does the speed of an object affect the perception of time?

According to Einstein's theory of relativity, the speed of an object can affect the perception of time. This is because as an object's speed increases, its energy also increases, causing time to move slower for that object. As a result, time may appear to be moving at a different rate for someone observing the object's movement compared to someone who is traveling at the same speed as the object.

4. Can the speed of time be measured?

While we can measure the passage of time using clocks and other timekeeping devices, the concept of the "speed of time" is more subjective and cannot be directly measured. Our perception of time can vary based on factors such as our age, emotions, and level of engagement, making it difficult to quantify the speed of time.

5. How does the theory of time dilation explain changes in the perception of time?

The theory of time dilation, part of Einstein's theory of relativity, states that time can move at different speeds for different observers depending on their relative speeds and gravitational forces. This means that someone traveling at high speeds or in a strong gravitational field will experience time differently compared to someone at rest. This theory helps to explain why time can seem to speed up or slow down depending on our circumstances.
