The article is half a page long, but if you don’t feel like reading, at the bottom of the page you can watch it on video.
Had there been a previous Universe, Universes that one after the other had been heading towards their evolution, explosion after explosion? Is the Universe cyclic? I didn’t know. What is certain is that it is the present Universe that I was seeing, but not with the knowledge that I would like. It’s possible that this was the last one, but will there be others? Have there been previous ones?
There is no simple explanation to be sought. It cannot be said that cosmic inflation shapes the ‘dark matter or dark energies’, it is something else. The astronomer Hubble showed us with his Constant that the Universe is moving away from itself. But there have been so many events in it that there are an infinite number of directions in which it is heading. What he is perhaps saying is that it is possible that everything known and unknown will eventually lose force and begin the process of contracting in on itself. In the end, as this constant lost strength, the other force appeared: gravity (which was there, but Hubble’s constant had beaten it). And what we call the Cyclic Universe began to contract (it was the Big Crunch).
Everything was supposed to be there: matter, antimatter, dark energy, dark matter… stars, planets, galaxies, black holes… All the astrophysics! We cannot know exactly what that previous Universe was made of or what its characteristics were; it is impossible to know what it had to evolve into. That was the birth of a new Universe, ours. Energy, time, space; the visible and the invisible… And more things appeared and were ready to start a new process of transformation. That which had not been achieved with the previous ones, and a new cycle began; but in the new one its fundamental forces also appeared, but perhaps somewhat different from the previous Universe.
In the previous nucleus of which it is impossible to know either the size or its internal movements, something appeared which we might call instability pushed to the limit of what that nucleus could withstand, and being unable to maintain itself in that situation… it exploded. It may be that one day all these cycles will have achieved their intended realisation; but this would also be something else unimaginable.
Everything else we are only beginning to know, but we have it here to observe. Although we have used all our technology including the exploration of the Solar System, as well as space telescopes to go beyond, to those origins we would like to know, and we have seen the visible matter (that which emits its own light), although we also sense that there is the invisible, infrared, microwave, radio waves, gamma rays, X-rays, ultraviolet light…. The dark ones. All this has led us to realise that we still know very little about this phenomenon that surrounds us and in which we are, and which we call the amazing Universe.
