Re: Origin of the Universe
The oldest galaxy candidate ever seen is CEERS-93316 whose image ( JWST ) correspond to 235 million years after the Big Bang, In a astronomy article I read: " They will have to spend about 250 million years from the Big Bang, wich gave rise to the Cosmos, to see the birth of the first stars in ...

Re: Origin of the Universe
New JWST images show the oldest galaxies
ever discovered.
These galaxies are well formed and relatively
close to the start of the Big Bang.
This contradicts the predictions of Big Bang
theory, since, at these distance galaxies in the
process of formation should be seen. and not
well-formed galaxies.

Re: Voyager I and II
It seems that the technicians responsible for
Voyager 1 have already corrected the failure of
the probe-
Some time ago Voyager 1 began to send to Earth
various data not compatible with reality.
The problem: the ship was processing data
on a computer out of use.

Re: Flowers Around The House
Some time ago I was given a small cactus about 7 cm high, it had a red hat. A kitten voted him to the floor several times. I put him outside my window in a porcelain cup as a planter. Well, there he became thin and grew a lot. Today he is 50 cm. tall ( he no longer has the red hat.) I do not know wh...

Re: Origin of the Universe
I do not want to annoy the readers. Nothing of that. But, what is the idea? I think that the point of infinite density, where the Universe originated, according to the current Big Bang theory, is the " Aquiles heel " of this theory. Indeed. I believe that no one has empirically demostrated...

I met a smart watch, which works as a satellite
of a smartphone.
This watch records calls, measures blood pressure,
heart rate, even counts the daily steps of a person.

Re: What caused the big bang
I think that the Big Bang did not start from a point
of infinite density, but it arose from a large amount
of cold, compact and high density matter.
Before the Big Bang there was matter.
But, what caused this explosion?
Possibly a series nuclear fission reaction, generated
