Is there a now?

So...with the expected attempted evasion nonsense out of the way...

...DO YOU?

Frank,

You need to recognize that you voluntarily have decided to live in your own world where you have no idea if you yourself are real.

The definition of reality applies to several meanings, and as a general concept you can obtained it from wikipedia:

https://en.wikipedia.org/wiki/Reality

Reality is the conjectured state of things as they actually exist, rather than as they may appear or might be imagined.[1] In a wider definition, reality includes everything that is and has been, whether or not it is observable or comprehensible. A still more broad definition includes everything that has existed, exists, or will exist.

As you noticed it, it is a common understanding that reality in general terms can include even what "it has been", for example, it is a reality that the US Independence day was in July 4, 1776."

I have explained you the specific definition of physical reality.

"Now" is a specific physical reality, because is the current status and location of everything in the universe.

"Now" becomes a fact.

Facts DO need explanation in the sense that an item of experience sometimes needs to be evaluated regarding its alleged facticity. Someone has said that facts are little theories.

You seem to be having a difficult time actually answering this question, Carlos.

I do not know the true nature of the REALITY of existence. Do you?

You might want to re-read that definition up above. It should help you to understand the question...and help you come up with an answer...rather than an attempted evasion.

"Extremely short, sharp flash of radio waves from unknown source in the universe, caught as it was happening
...Over the past few years, astronomers have observed a new phenomenon, a brief burst of radio waves, lasting only a few milliseconds. It was first seen by chance in 2007, when astronomers went through archival data from the Parkes Radio Telescope in Eastern Australia. Since then we have seen six more such bursts in the Parkes telescope's data and a seventh burst was found in the data from the Arecibo telescope in Puerto Rico. They were almost all discovered long after they had occurred, but then astronomers began to look specifically for them right as they happen.

A team of astronomers in Australia developed a technique to search for these 'Fast Radio Bursts', so they could look for the bursts in real time. The technique worked and now a group of astronomers, led by Emily Petroff (Swinburne University of Technology), have succeeded in observing the first 'live' burst with the Parkes telescope. The characteristics of the event indicated that the source of the burst was up to 5.5 billion light years from Earth"

I ASK AGAIN: Do you know the true nature of the REALITY of existence?

And my answer still is the same: I know what reality is.

From here, your question is similar as to say, do you know the true nature of life? or, do you know the true nature of dreams? or, do you know the true nature of jokes?

Pure cheap philosophy, because the answer is just unknown.

And my point is that you don't need to know the nature of the reality of jokes in order to laugh when you hear one.

The same as well, your position is ridiculous when you pretend to have doubts that physical reality does exist, that you yourself probably are not "real" just because you never discovered the true nature of existence.

In order for you to validate your point, you must to show your argument, your evidence, your ideas, explaining why you think that you are not real.

In this case, when is about "now" and "the existing universe", you must explain why you think there is no "now" and why you think that you don't exist physically.

To say that "you don't know", and that "you have doubts", and come with questions to the unknown, your words are just dogs barking to the Moon.
