DARK ENERGY ?????
Dark Energy and Dark Matter are the biggest challenge to physics and cosmologists today.
95% of the energy of the universe is a complete mystery.
A BIT ABOUT ME
A wanna be scientist. Always wanted to be a scientist from 7 years old. In fact I did get a BsC hons degree in Chemistry from Glasgow University in 1972. I went to uni to do maths as that was my best subject at school, but gave up after 2 years when we got to ‘imaginary numbers’. I like things to be real. Gave up physics too after 2 years. It was boring then. If we had been studying black holes it might have been different. So I did chemistry, but physical chemistry, my paper on the photo-degradation of poly methyl methacrylate is gathering dust somewhere but I like to think that the world sees more clearly as a result.
I never intended to write this stuff on cosmology although I did write to Brian Cox and Steven Hawking years ago about the cyclical nature of the universe. I hadn’t heard about Dark Energy then. It was only when I got a proper smart phone a couple of years ago that I got plugged into YouTube with the help of Google’s algorithms.
One day I saw a video on Dark Energy produced by PBS Spacetime. There was Matt O'Dowd talking about a mysterious influence that physicists have come to call Dark Energy.
I didn’t even know that the universe was expanding.
What really caught my attention was that pie chart. 95% of the energy of the universe was a complete mystery. Surely not. I must have misunderstood. Soon it was clear - they all said -
"We have no idea what Dark Energy is. Your guess is as good as mine".
But to me it was obvious. Every day I expected to find a simple reason why I was wrong. Instead I kept finding stuff that supported my idea and even some ways in which it could be tested. The more I researched, the simpler it became, and even more things fell into place.
In a BIG UNIVERSE, which is much bigger and older than we think it's all much simpler.
The expansion of the universe
Where did all this stuff come from?
The matter/antimatter problem.
And without the need to devise new particles, mysterious new forces or creative mathematics.
I don’t expect anyone to agree with me. What I do want is that the people who do the hard graft with telescopes and computer analysis are at least aware of the possibility that there could be a big cosmos out there beyond our observable universe. We need to start looking for it.
It is possible that we already have the data to confirm it. Somebody may have looked at their data and said ‘that’s funny’ but ignored it as equipment error. There may be a ‘petri dish full of green stuff’ in a drawer which needs a second look.
Who would not want to be the first person to observe an event from beyond our universe and before time began.
I need a cosmological Magellan to probe beyond our understanding of the universe and confirm my belief that the universe has always been much bigger than we thought.
Lambda Cold Dark Matter (LCDM) explains a great deal about the structure of the universe. But how much does it tell us about the big questions of cosmology?
It tells us nothing about where all the stuff of the universe came from.
It tells us little about how the universe will end.
Even worse, it leaves 95% of our universe unexplained. Even the placeholders for this 95%, Dark Matter and Dark Energy, are being questioned more and more.
How did it all start? Where did all this stuff come from? The matter/antimatter problem? To quote Dan Hooper “it's the most perplexing problem for more than 50 years”
Dark Matter? Not only can we not detect it, we have no idea what it is.
Dark Energy? “An unknown form of energy that affects the universe on the largest scales. ... Without introducing a new form of energy, there was no way to explain how an accelerating universe could be measured”. Wikipedia.
The usual explanations of Dark Energy are totally unsatisfactory - “the energy of the vacuum which doesn’t dilute as space expands”.
The field of cosmology is a natural for the amateur scientist; a pastime which was once honourable, but is too often today scorned by the professionals. Any enquiring mind wants to know how it all started and how it will end.
When those answers are not forthcoming, one is obliged to search for an explanation.
Cosmology has some serious problems.
To those trying to defend LCDM I turn to Stacy McGaugh’s blog January 29 2019:-
“we should remember that we once endowed SCDM with the same absolute certainty we now attribute to LCDM. I was there, 3,000 internet years ago, when SCDM failed. There is nothing so sacred in LCDM that it can’t suffer the same fate, as has every single cosmology ever devised by humanity.”
THE UNIVERSE HAS ALWAYS BEEN BIGGER AND OLDER THAN WE THOUGHT.
