It seems to have happened at the end of January 2016, when an Italian mathematician named Gianluca Pisanelli had been analysing the structure of the solar system in his home town of Cuneo, in the province of Pisa.
Pisanelli had observed that, over the course of 4,500 years, the Sun, Moon and planets had changed their positions.
His data was a useful window into the nature of our universe, but it didn’t tell the whole story.
In fact, the data had provided the first indication of a potential gravitational effect that had been lurking in the universe for many billions of years.
What could it be?
Could it be that we have entered a new epoch of life?
It was the question that came to mind when I started reading about the possibility of life on Earth.
How could we be so close to the Sun and have so little life on other planets?
And what could we do to prevent extinction from the most extreme climate changes?
It had to be life, after all, and the odds were that if we could find life elsewhere, it was going to be very special.
We had to find it somewhere in the cosmos.
As I read about Pisanella’s work, I realised that, if life was out there, we’d have to find the first life on our planet, which meant that it had to exist on other worlds too.
If life was everywhere, there must be other life out there somewhere.
It was all very exciting, and all very very speculative, but if life were on other Earths, it would mean that we would also have to discover life elsewhere.
And so I began to wonder if there was a way to go to the other side of the universe and discover life there.
Could there be other universes that we’d never discovered?
Could we just make a few trips to a distant star and find life?
I started thinking about it again.
Could life be living in a universe with an immense number of planets?
Or could life be more like the star we inhabit on Earth?
As I continued to research, I came across several articles on the subject.
One of them, written by a professor at the University of New South Wales, looked at a scenario in which there was an alien civilisation on a distant planet that had built a civilisation on the planet’s surface, in what we would now call the “near future”.
As the aliens had built what they called “an artificial gravity well” for themselves, they could then have built a huge civilisation on another planet, and sent it on a journey through space.
What if there were life on another Earth, in an “alien” planet?
I began wondering whether or not there was some kind of civilisation out there in the far future, that we were just not yet discovering.
A new way of thinking The next few years were a whirlwind.
As it turns out, there was indeed a very simple answer to my question.
As the universe aged, the number of worlds that were inhabited by aliens grew exponentially.
A planet in the distant future, such as an Earth-like planet, would have had to have a population of one billion people, compared to about three billion on Earth today.
This was why the universe was so vast.
There were so many planets out there.
The size of the Milky Way galaxy would have to be far bigger than what we can see today to make up for the difference in our universe’s age, which is about ten billion years.
In the far distant future that is, when we have reached the end-of-the-line and the beginning of the next big bang, the Universe will have gone through another big expansion, which would have stretched out the number and range of worlds even further.
We would then be looking at the beginning stages of an expanding universe, a time in the history of the Universe when all the matter that is in the Universe was still very small.
The expansion of the cosmos was like a flood, and as the Universe cooled and grew denser, it began to compress the space around us, leaving behind a vast “ring of stars” that stretched for billions of light-years across the cosmos and beyond.
This ring of stars was what we see today as the Milkyway galaxy.
But this was also what the aliens would have been doing when they built the gravity well.
They would have built an artificial gravity field on the surface of their home planet, using massive telescopes that could zoom in on the far side of our Galaxy to capture the distant stars that are no longer in our line of sight.
This would then have been the point where the aliens could have built their “cosmic society”.
If this is correct, then life could have been living on other, less dense planets too.
In a way, life could be on a different planet from us, but not on another one, and so we wouldn’t know what the other life on that planet looked like.
In other words, the
