I have had this sense for a number of years that linear time as we perceive it has been speeding up. This moment of rising awareness is also called "The Quickening" by some.
Its hard thing to prove being that any physical device (mechanical clock) or energy reference device (atomic clock) one could use is by definition also speeding up as it's all within this illusion of light we call physicality.
Yet we can sense it because our minds are outside of time. We feel it. It's why we do things in advance of something happening/manifesting in the present now. And sometimes when were are really focused on a creation, time doesn't move at all.
I found this short video on how to prove it via a completely analog means and it makes sense. I used this technique as a kid to determine how far away a lightening strike was, which is about a mile per second in the time delay of the thunder from the flash.
I thought I'd drop this short video here if you are interested in how to prove time is speeding up. This is nothing earth changing in itself but it's so simple to do. I don't agree with many things Dick Algire says about the future of money, but this test of his on time speeding up is pure brilliance.
