Horizon: Is everything we know about the universe wrong? (March 2010)

Even though, I am not a scientist, I found this programme particularly exciting because you look at it from a theistic perspective then the fact that we can’t answer many of these questions is because there is a God out there!

I thought I would share some points I put down;

The first problem with the Big Bang theory…

Is that in any normal explosion, we do not see a uniform temperature forming and all the aspects of the end product look different. However, on Earth we have a relatively uniform temperature range and all aspects look fairly similar.

How was this problem resolved?

The theory of inflation was created. In the theory of inflation the world slowly expands and once a uniform temperature is created, a quick bang occurs and the universe is created.

But what caused the inflation?

Nobody knows.

What is dark matter?

When rotational speeds of galaxies were measured, scientists saw that they were moving way faster than what they expected. This also contradicted Newton’s laws. There simply is not enough gravity for galaxies to be moving at this speed.Therefore, there must be another force like gravity which is causing this.

In particle physics, there are 24 types of particles but according to the concept of super symmetry there are another 24. These other 24 spin in different ways and are invisible (in the sense that they do not emit or reflect light).

Dark matter is almost like an invisible gravity and these invisible particles are claimed to be dark matter. However, the problem is these particles are said to pass normal matter like us all the time so how can they be measured.

Well currently research is being done half a mile underground and last December two unusual incidents might be indicating there is dark matter, However, two incidents is too few to prove anything.

If you are wondering how all of these theories has come about and how scientists know all this – it relates  to maths. Dark matter is the missing piece to what maths predicts and it puts the standard model back on the scene.

However there is another fundamental problem.

Rather than slowing down, as the standard model suggests, there is now evidence that the universe is accelerating in expansion.

The big bang is still banging. And yes you’ve got it there is another dark element to be added. Dark energy. This is the new force powering the universe.

With this as well they do not now what it is. All they know it is dark and expanding. One suggestion is that is could be a type of odd gravity that is making two distant thing repel. And yet this was something that was created to make sense of the mathematical modelling of the Big Bang theory in real terms.

There must be something in nothing. Vacuums and the mere emptiness between galaxies is now said to contain dark energy. It has a weird property too. As it causes the universe to expand, all the gaps are being filled with more dark energy. It is actually increasing.

Sounding simple, here is the creation story so far;

1) Universe starts with a bang

2) Then it suddenly inflates

3)Dark matter forms

4)This helps galaxies emerge

5) Then the universe starts to expand slowly

6) Dark energy takes over – stretching the universe further

Yet, there is another challenge…

There appears to be a distortion in the light coming from energy backgrounds, it seems to be coming from a kind of movement. This does not fit the standard model in the mathematical model and in reality.

All the galaxies appear to be moving in an inexplicable way towards one another on a particular point. It is caused by a mysterious and unseen force. Cosmologists call this the Dark Flow.

It suggest that the universe is part of a multiverse. It also supports the theory of inflation because inflation never completely ends. So what it is trying to say is that in some areas inflation has finished but in others it is still happening.

Could this be evidence that we are not alone?

Is the cosmology changing?

Is the standard model correct?

The programme discusses all of these points in further detail. (Please note I am not a science student and my knowledge of science is limited so some of my information may be wrong. USE THIS INFORMATION AT YOUR OWN RISK!)
