What percentage of the speed of light does time dilation become noticeable?

That depends on how long the moving clock keeps moving before you take it into
the lab and measure its error, and it also depends on how small an error you can
measure.
A clock flown around the world on an airplane arrives with measurable error that
corresponds to the error expected due to relativistic time dilation. Also, corrections
are routinely included in decoding the signals from GPS satellites to account for the
relativistic error in their on-board clocks due to their speed in orbit. If corrections are
not made, the error in GPS positioning is definitely noticeable.

Is time dilation is apparent or actual change?
actual, time really does slow down close to the speed of light
What occurs when energy is tranferred from light waves to matter?
If the matter absorbs light, then its internal energy increases, and it becomes warmer. But it takes a truly huge amount of light to produce a noticeable effect ... which just goes to show how sensitive our eyes are to tiny amounts of light energy.
Do dark colors attract more light than light colors?
The don't exactly "attract" the light; rather, if light falls on them, a larger percentage of the light will be absorbed.
Why is it that a sheet of white paper is a good reflector of light?
That's the definition of "white" - that it reflects a large percentage of the incoming light (all colors get reflected by more or less the same percentage).
How does light rays behave to produce different colors using different objects?
White light is a mixture of different colors. A red object (for example) would reflect a greater percentage of red light, and a lesser percentage of other colors, thus making the light that you see redder.
Does time dilation occur near the speed of light?
Time dilation always occurs, at ANY speed. The reason it was unknown for solong is that it doesn't become noticeable to us at any speed where we have anydaily experience. But as soon as we had atomic clocks capable of measuringinsanely tiny time differences, and began using them to look for time dilation,there it was, right in front of us, all over the place, in just the predicted amounts.
What are the examples of dilation in real life?
The iris in the eye dilating in low light.
Why don't we experience time dilation in everyday life?
We do experience a form of time dilation in everyday life, but the effects are extremely small. Time dilation occurs due to differences in gravitational potential and velocities. In our daily lives, these differences are relatively insignificant compared to extreme situations, such as near a black hole or moving at speeds close to the speed of light, where the effects of time dilation become much more pronounced.
Does time dilation have any effect on explosions?
In principle, yes. But just like everything else in our daily experience of life on Earth, the effect is so small that it's completely undetectable and un-noticeable. Even the particles involved in an explosion never reach a significant fraction of the speed of light.
Which process allows more light to reach the periphery of the retina?
Dilation of the pupil
What happened When a person absorb light?
-- His skin or his clothing appear dark. -- Technically, his skin and his clothing become slightly warmer, but the quantity of energy involved is normally so slight that the effect is not noticeable.
Are black light tattoos noticeable during the day?
They are only noticeable under black lights, unless you are looking for it and look really closely, then you can see light ink. The tattoo only last for about 6 months.
How can anyone know the effects of time dilation when you have no means of reaching any speed near the speed of light?
While it is true that reaching speeds close to the speed of light is currently not within our technological capabilities, the effects of time dilation have been experimentally verified. Particle accelerators, such as the Large Hadron Collider, accelerate particles to speeds close to the speed of light, allowing scientists to observe and measure time dilation. Additionally, the Global Positioning System (GPS) relies on correcting for the effects of time dilation due to the different speeds of satellites in orbit.
Is time dilation is apparent or actual change?
actual, time really does slow down close to the speed of light
How does light affect the pupil of the eye?
With high intensity light your pupil constricts. This happens to protect your retina from damage by light of high intensity.

What percentage of the sun is heat and what percentage is light?
