IS THERE LIFE ELSEWHERE? – THE BIG BANG

For the next few posts I will talk about the big question – Is there life elsewhere? But to do that I need to go back over 13 billion years to the formation of the Universe. We need to understand how and where we came from to be able to speculate about other life forms in the cosmos.

The accepted current basis for the start of our universe is The Big Bang Theory; an event that occurred 13.8 billion years ago. A cataclysmic explosion from a single point that resulted in all the matter [that we know about] that subsequently coalesced into galaxies, stars, solar systems and planets. And of course Earth.

I have a problem with this because the theory says that before the big bang there was nothing – at least I think that what it says. I have never been able to fathom out what the theory actually claims the pre big bang state to be – maybe my readers will have views? 

I am a great believer in the Laws of Thermodynamics and the 1st law at its simplest says to me – “matter can neither be created nor destroyed but can be moved from one form to another.” Thus I am comfortable with the notion that matter is timeless – it has always been there and always will be – in some form or another.

So here’s my theory for the Universe –

Yes, there was a big bang 13.8 billion years ago and all the galaxies are flying apart [some will collide]. The accepted theory says that eventually these galaxies will run out of steam and slow down to a state of maximum entropy – disorder – and the universe will ‘die’. I don’t believe this and consider that as the galaxies start to slow down their incredible gravity will act first as a brake and then as an attractive force which reverses their direction such that they start rushing towards one another again. Ultimately all the galaxies [all matter] will collapse in on itself forming the ultimate Black Hole. BH_LMCHowever the forces inside this black hole will be so incredibly high that they will trigger the mother of all explosions – another Big Bang in say 28 billion years time. I believe that this is what happened just before our Big Bang 13.8 billion years ago. Thus matter rushing towards itself, exploding, rushing away and then rushing towards itself again is a repeat cycle that is timeless. I would love to hear your views on this hypothesis.

The experts say otherwise and I can offer no proof. But they don’t know everything. We have just proved [?] the existence of another particle – the Higgs Boson which helps to account for some of the matter we don’t understand. But we still can’t account for 70% of the matter in the universe. We call this dark matter and dark energy and some believe it to be the ‘glue’ that holds everything together.

Perhaps it is another dimension that something, if it was clever enough, might utilise for galactic and inter-galactic travel. And maybe that something is a Dicepteron! But you will have to wait for Volumes 2 and 3 for the answer to that.

But whatever theory we accept for the beginning, the Universe is immense beyond belief. We can now ‘see’ images from just after the Big Bang. That light has been travelling for over 13 billion years at 300,000 kilometres every second!  Light from our Sun which is approximately 150 million kilometres away takes just over 8 minutes to reach Earth. The nearest stars that we see are 5 – 10 light years away and the Andromeda galaxy is a staggering 2.5 million light years away but that is a short hop compared to the size of the Universe.

Our immense Universe contains billions of galaxies each containing billions of stars with orbiting solar systems. One estimate says there could be 1 billion potentially habitable planets in our galaxy – The Milky Way and we are now discovering new planets around distant stars on a daily basis.

So the first prerequisite for the question – Is their life elsewhere? – is numbers – there are so many potential Earth-like planets that somewhere else conditions would be equitable for life.

But how did life form on planet Earth? This I will discuss in the next post. 

A final thought – there may be more than one Universe!
