It does! I started writing this over 12 hours ago but then the battery on my tablet went flat so I had to wait until now .
Anyway, time does tick by, sometimes I know exactly when the alarm is going to go off, and it does. I can wake up a second before the alarm clock goes off….nothing is clicking or whirring or spinning to give me a cue or a clue. Same with the alarm on our oven, last night I got up from my chair to check it just before it went off.
One explanation is the brain has tiny cells beating regularly giving us a sense of time. There are also electric nodes in your heart that regulate your heartbeat, and your breathing is a regular rhythm allowing you to get just the right amount of air.
But what is time, why do we feel times arrow? Why does a cup fall and then break as it hits the floor? Why isn’t it on the floor then bouncing back up onto the table, reforming from smashed to solid in a second? There is something called entropy, everything breaks down over time. Everything tends towards chaos. The Universe is cooling, as space expands. Astrophysicists speak of the heat death of the universe as everything spreads out and cools towards absolute zero. Galaxies are flying away from each other. If things continue, in many billions or trillions of years, we would have completely black skies, no stars in sight. Our Sun will have cooled to a husk of burnt matter and all the other Stars will fly off away for us. There is something called red shift, as galaxies move away their light shifts towards the red end of the spectrum, the larger the red shift the faster they are moving. There are theories about things called dark energy and dark matter that try to explain this, but I wouldn’t know where to start with that aspect of space time.
Time ticks for everything, although time may not actually exist, it might just be our way of measuring the passing of things happening, but not understanding the universe. But if it is real there may be an advantage of time. The end of the universe or more likely its continuous, infinite existence, will not happen in our time. But a long long long time in the future.
