Present moment, does it exist?
Yes, present moment exists, but it's not fix instead it's fluid.
For example, if we set the boundary of the present moment precise to 1 second:
If present moment is 1:00:00 pm.
1 second later, the present moment is or move to 1:00:01 pm.
1 second later, the present moment is or move to 1:00:02 pm.
1 second later, the present moment is or move to 1:00:03 pm.
1 second later, the present moment is or move to 1:00:04 pm.
1 second later, the present moment is or move to 1:00:05 pm.
1 second later, the present moment is or move to 1:00:06 pm.
As show, present moment is moving as seconds gone by, it doesn't stay at a fix time.
Is it possible that the present moment does not exist?
For example, at 1:00:00 pm we can say that present moment has not yet exist at 2:00:00 pm. But when time arrive to 2:00:00 pm, present moment will exist at 2:00:00 pm.
When time arrive to 3:00:00 pm, we can say that present moment used to be EXISTED at 2:00:00 pm, CURRENT present moment CURRENTLY does not EXIST at 2:00:00 pm, CURRENT present moment EXIST at 3:00:00 pm.
In the moment you start to think, "this is the present moment" it is no longer the moment you started to think it was
Okay, for example if at 1:00:00 pm, you look at a clock and confirm 1:00:00 pm is the present moment.
1 second later at 1:00:01 pm, 1:00:00 pm is no longer the present moment.
At 1:00:01 pm, the present moment is 1:00:01 pm.
What's the problem?
Is "present moment" an illusion?
No.
