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

The James Webb telescope is sending back a series of never-before-seen images of the early Universe. This arsenal of new Knowledge could ( eventually ) shake the current theory of Bing Bang, totally or partially and, of course, the origin of the Universe by a singularity from a point of infinite den...

Re: Origin of the Universe

Thanks, Orca, your explanation is very interesting Well, let is leave infinite density and teology aside. By a space-time singularity suddenly a point appears containing matter, energy, space and time. This is what I call " cosmic magic" There must be some better scientific explanation for...

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...

Re: Origin of the Universe

( Second school of thought) In this school there are very bold theories- One of them support que in the Big Bang arose the Universe with positive time and at the same time an anti-universe with negative time, back wards. It support that when a particle arises, it is anti-particle is created. Anti-un...

Re: Participate in Citizen Science or Smartphone Science

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.
This device is very interesting and useful

About this topic, two great school of thought are opened. The first school of thought support that the Universe arose with the Big Bang, from a point of infinite density. Before the Big Bang there was nothing. This theory is "armored" and somewhat dogmatic. The second school of thought sup...

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
the Big Bang
