Anthropologically speaking this is the best answer. Our brain needs a certain span of time to establish perceived reality.

No physical mechanisms predefines future events (or is there one ?).

So, I could state that the future does not exist yet and the past as ceased to exist.

in that statement I have a problem with the definition of existence. Does the definition of existence exist itself ? This is (is it ?) more a problem of terminology than philosophy or physics.

Bonne fête Camus !

Votre imagination est juste car je n'étais pas au courant.

Thanks for your time and attention.

We have never observed anything in the universe just popping into existence from nothing (...)

if we did, that would be a major shift in physics. in this regards I heard of (or read of) two candidates :
.1 if universe's expansion continues to accelerate, (it would mean) dark energy is increassing.
.2 an excess of hydrogen (clouds) outside of galaxies was observed that is difficult to explain with current cosmology.

I know these are not direct observation of something popping up, ...but still.

I think there must be a mechanism behind the (stated) laws. This is what interest my reflection.

On a side note :
is there something in nature that prescribes the conservation of energy ?

(please, if you answer this, do so under my other comment (big bang...) ...I don't want to lose track of the main topic).

I am trying to find a loophole for the origin of the big Bang or whatever created the universe.

P.S. What I'm saying could be something like : "if a system is empty it doesn't contain the first law".

My misquotation was on purpose.
in the same thread of thoughts : if there was a system without the first law, anything could appear as if by magic !
...that is, until the 1st law appears.

Last i bought was $1.71 CAD / kg
(made in Canada www.italpasta.com )

@anotherlemmyuser 's is $1.06 us$ / 750g so ... $1.41 us$ / kg ... , so ... $1.90 CAD / kg

The price has I've got in Canada, is about 10% lower than that one in Malaysia.

Humanity is so stupid when it comes to "territory" and we are not the only species that acts like beasts about it.

I read through these and try to understand them but mostly I don't like those theories, because (in part) more and more there are disparities between them and observations.

So I came up with some ideas myself, one of which I wrote in here :
"New physical cosmological model : is it coherent ?"

But it may take a few years or a few thousand before we have a good cosmology.

At sea level air is about 1.25 kg/m³, so for one cubic kilometer cloud that is :
1 250 000 tons.

I put your result into table ~~to show a problem at 51 km and above... since density decreases monotically with altitude.~~

Clouds can be easily 10 cubic km.
