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.

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.

 

1^st^ law of thermodynamics :
There is something that will always be the same.
2^nd^ law of thermodynamics :
Everything else always changes and never will be what it was before.

i made this post (one month ago) :
How to browse ipfs:// ?
Bottom line : it went nowhere.

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

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.~~

mass (tons) altitude (km)
1 250 000 0
364 000 11
88 000 20
860 51
64 71

Clouds can be easily 10 cubic km.

~~I did make~~ I have made many mistakes, much worse than this one and on many occasions. I would say : don't be so hard on yourself since it's important to forgive ourselves.

I do believe the following correction should be made again to your text though :

Gravity is an [edit: inverse squared] function, so it gets weaker at ~~an exponential~~ a squared rate as you move away from the source.

I believe in this community you have to write the word "rule" in the title, like so :
Banana? Banana rules !
(you can edit the title even after posting, that is, if you want so)

 

The following mechanism, by continually creating matter in the universe, if self coherent, would solve many unsolved physical problems : this cosmology would do without a big bang.

3d interference pattern of gravitational waves would create rogue waves at specific points in SpaceTime that would create matter and the CMB.

Creation of matter and gravity fields, at net zero energy would increase the expansion of the universe.

The perfect black body curve of the CMB would result from the exponential expansion of the universe.

Just wanted to browse ipfs. So I went here :
https://en.m.wikipedia.org/wiki/InterPlanetary_File_System

it says... :Opera (browser) for Android has default support for IPFS, allowing mobile users to browse ipfs:// links to access data on the IPFS network.

So I just need one "ipfs:// links" right ?
... let's find one !

So I navigate through these... :https://en.m.wikipedia.org/wiki/Filecoin https://filecoin.io/ https://filscan.io/tipset/chain/ https://filscan.io/miner/f01043193/
There, I finally get a link which I try and... it crashes the browser !

Do you know an easy way to get to one of those links (ipfs://) from a browser ?
