In summary, a scientist has said that time is slowing down. They provide a proof that loss of time has to be smooth (in the sense of a smooth graph) so we would experience it as a slowing down of time rather than just having time stop. They also say that slowing down of time is measurable as an acceleration of expansion.

http://www.opfocus.org/index.php?topic=story&v=8&s=4 - Light slowing down

I read these articles some time ago. I was just wondering if anyone else has put any thought into this. Anyone have any reason why this cannot be true?

Interesting stuff! I'm disappointed that no one has commented...c'mon, people...

To me, the slowing of time seems more sensible than dark energy.

In the first link, not enough information is given. What does it mean for time to "slow down" yet allow us to see the effects of it? In any case, we still have the issue that the universal expansion rate has changed and was not always speeding up.

Second link: see other discussions on this forum. You can't just change the speed of light. If you changed things to make the measured speed of light different, other things would change too. It certainly hasn't changed in the last 30 years!

Even if the speed of light slowed down "c" would still be 186,000miles/second, its just that we would have to separate the universal speed limit from the speed of light.

Interesting. I think I have some sort of idea.

Here's the original paper. I don't understand it, but it seems to be saying that the universe is embedded in hyperspace with coordinate ξ and the proper time of the universe T(ξ) is slowing down with ξ. It gives a proof that loss of time has to be smooth (in the sense of a smooth graph) so we would experience it as a slowing down of time rather than just having time stop. Slowing down of time is measurable as an acceleration of expansion.

If that's a correct reading, it's extremely sloppy to change coordinates without telling anyone. Then again they'd probably slap me for calling their theory hyperspace :-/

FAQ: Is Time Slowing Down? Scientists Weigh In

Is time actually slowing down?

There is currently no scientific evidence to suggest that time is actually slowing down. The concept of time is subjective and can vary depending on factors such as gravity and velocity, but there is no indication that time itself is changing.

What causes the perception of time slowing down?

The perception of time slowing down can be caused by a variety of factors, such as heightened emotions or intense focus on a particular task. It can also be influenced by changes in the brain's processing speed or the amount of information being taken in.

How do scientists study the concept of time?

Scientists study time through various disciplines such as physics, psychology, and neuroscience. They use techniques such as measuring the speed of light, studying brain activity, and conducting experiments to understand the nature of time.

Can time be reversed or manipulated?

There is currently no evidence to suggest that time can be reversed or manipulated. While theories such as time travel exist, they are purely hypothetical and have not been scientifically proven.

Does time slow down in certain situations, such as near a black hole?

According to Einstein's theory of relativity, time can appear to slow down in situations with strong gravitational forces, such as near a black hole. However, this is a relative effect and does not mean that time is actually slowing down for everyone in the universe.
