If time slows down near a massive body like the Earth, is that actually the slowing down of time our is it just the slowing down of light?
LJFurniss said:"Light moves at the exact same speed in all reference frames."
"The Slowing of Time: Exploring Light Near Mass" is a scientific concept that explains how time appears to slow down as an object approaches the speed of light. This phenomenon was first described by Albert Einstein in his theory of relativity.
In Einstein's theory of relativity, mass and energy are equivalent and can curve the fabric of space-time. As an object with mass moves through this curved space-time, it experiences a slowing of time due to the increased gravitational pull.
One of the most well-known pieces of evidence is the famous "twin paradox" where one twin travels in space at near the speed of light and returns to Earth to find that time has passed much slower for them than their twin who remained on Earth. Additionally, precise atomic clocks have been used to measure the effects of gravity on time, confirming the theory.
The slowing of time near mass is a crucial aspect of Einstein's theory of relativity, which is the foundation for our current understanding of the universe. It helps explain many phenomena, such as the behavior of objects in space and the bending of light near massive objects like black holes.
Yes, we can observe the slowing of time near mass in everyday life. For example, GPS satellites, which are moving at high speeds and are affected by Earth's gravitational pull, have to account for the slowing of time in order to provide accurate navigation. This effect is also seen in the redshift of light from distant galaxies due to the expansion of the universe.
