Big Bang Theory

I believe in the big bang theory, the earth, planets etc, came about from that moment in time. I have read a few articles and watched a few programs about it over the years, and have found nothing to change my mind.
I also believe in a greater being(s), who were responsible for life on earth, meaning that we are not alone.
How could we be, with an untold numbers of planets in the universe why would there only be one very small planet with life.

I have cut down the information because there was too much and lots the average person would know nothing about, i hope you enjoy it and enjoy the read.


First, of all the experts are reasonably certain that the universe had a beginning

Second, galaxies are moving away from us at speeds equal to their distance.

The Big Bang was at the very beginning of our universe. Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning.

Before that moment there was nothing, after it there was our universe. The big bang theory is an effort to explain what happened during and after that moment.

Our universe sprang into existence around 13.7 billion years ago. Where did it come from? no-one knows for sure.

It is thought to started at the core of “black holes.” Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that finite matter is actually squashed into infinite density.

These zones of infinite density are called “singularities.” Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something – a singularity.

According to the Big Bang model, the universe expanded from an extremely dense and hot state and continues to expand today. A common analogy explains that space itself is expanding, carrying galaxies with it. The graphic scheme above is an artist’s concept illustrating the expansion of a portion of a flat universe

After its initial appearance, it apparently inflated (the “Big Bang”), expanded and cooled, going from very, very small and very, very hot, to the size and temperature of our current universe.

It continues to expand and cool to this day and we are inside of it, creatures living on a unique planet, with several hundred billion other stars in a galaxy soaring through the cosmos, all of which is inside of an expanding universe that began as an infinitesimal singularity which appeared out for reasons unknown. According to the experts space itself is expanding, carrying galaxies with it.

Big Bang spacetime is the presence of horizons. Since the Universe has a finite age, and light travels at a finite speed, there may be events in the past whose light has not had time to reach us. This places a limit or a past horizon on the most distant objects that can be observed. Because space is expanding, and more distant objects are receding ever more quickly, light emitted by us today may never “catch up” to very distant objects.

Only gravitationally bound systems, such as galaxies, would remain together, and they too would be subject to heat death, as the Universe expands and cools. Other explanations of dark energy—so-called phantom energy theories—suggest that ultimately galaxy clusters, stars, planets, atoms, nuclei and matter itself will be torn apart by the ever-increasing expansion in a so-called Big Rip.

If the mass density of the Universe were greater than the critical density, then the Universe would reach a maximum size and then begin to collapse. It would become denser and hotter again, ending with a state that was similar to that in which it started—a Big Crunch.

If the universe was very, very hot as the Big Bang suggests, there should be some remnant of this heat. and proof was found In 1965, Radioastronomers Arno Penzias and Robert Wilson discovered it and they shared in the 1978 Nobel Prize for Physics for their discovery. This is thought to be the remnant which scientists were looking for.

The abundance of the “light elements” Hydrogen and Helium found in the observable universe are thought to support the Big Bang model of origins.

  1. Good read. I tried reading “A Brief History of Time” but had trouble really focusing as it was written so scientifically, for me at least. I think you saved me a lot of reading!

    Also, have you ever seen the televison show Ancient Aliens? Some of the things on the show are really far-fetched, but it’s still interesting to think about. Your first paragraph or two made me think that show might be of interest to you.

  2. I try to watch any programme on that line, i have an open mind about things.

    I think my post is fine to read, i cut all the baffling stuff out, i’ll keep an eye out for the show.

  3. This post was a great read. Thanks for publishing it.

  4. Harry, I am also fascinated by Big Bang theory and all the rest. I love a series called “Through the Wormhole” hosted by Morgan Freeman. It’s on one of the cable scientific channels, can’t recall which one. I think you would enjoy it. Many discoveries and theories are discussed — in a lucid, understandable way.

  5. Love astronomy! Great job summarizing a massively confusing topic! I look forward to your next one!

  6. Heavy stuff for a Sunday. 🙂

  7. Thank you for this post, Harry. It’s very interesting and I could understand it. 🙂

  8. I’m already working on a follow up post.

  9. sbmartin, thanks for that, i forgot to put two links in but the material in them is baffling.

  10. Maybe it’s me. Okay, it’s definitely me. I got lost (but “Lorna” means lost, so I get a free pass every time on that one). Here’s what happened:
    1. I thought this post was about the nerd-guys sit com
    2. Getting over that dashed expectation, I read on accepting that I may have to learn something of actual value, then that cute little typing smiley guy grabbed my attention.
    3. I really tried to focus, but when I read “black hole,” my mind seemed to get sucked into one.

    I feel like the dogs in the movie “Up!” My attention span is great until a squirrel passes. Oh well, I’ll try harder next time. I just take it on faith that the Big Bang theory is correct and the sit com is funny… 😉

  11. Doesn’t this stuff fascinate you every time! Gotta love it.
    What intrigues me the most is the theory that, if it began with the black hole, then there must have been matter even before that, for the black hole to exist (black holes are made of exploding star matters). So in that way, we are living in the recycled universe…

  12. Great post! Have you been keeping up to date on the supposed discovery of neutrinos at a speed greater than that of light?

  13. Great post Harry !!!

  14. I did – read it all that is 🙂

  15. You know I did very poorly in astronomy, but had the books been written in the way you wrote this post, I might have done much better. I really enjoyed reading this. 🙂

  16. Great post.
    YOu should do a sequel to this where you define how the humans will get crippled and destroyed with the passage of time 😉

  17. Brilliant post Harry love it and agree with the start of our universe and how it came about x Both my thoughts on this post were expressed by Lorna’s Voice, “Sheldon is my hero” and sayali611 x thanks guys for saving my fingers lol.
    I’m of the opinion, as the ant and probably every other inhabitant of this planet are, “the numbers being infinite so I wont list them all” is petri dish x

  18. I suppose its because most of my mind is in the clouds, why i find your post on the big bang very facinating. I’m hungry for more fulfilment in the sciences and the big bang marked the beginning as we know it. Why dont you come check me out and tell me what you think on my theories. Find me at

  19. Excellent post in simple terms for a complex subject. I have always been facinated by the beauty, complexiity, and wonder of the universe. I also believe that we are not alone. P.S. I haven’t gotten around to my versatile blogger award yet, but I did feature it at the top of my page. I left a link back to your blog. I want other bloggers to find and enjoy your wonderful blog.

  20. Thanks Sara, i thought it might be to heavy for you 🙂 green yes, but i don’t like so its being changed.

  21. I don’t know what you mean by this Sara, experiment where.

    You might try experimenting with colors which can be found within your avatars picture. Just a thought. I think you like to keep us all on our toes.

  22. Hey, you know what? I believe in “the big bang theory” of creation too. In the beginning, God spoke, and BANG! All the rest is history.

  23. It is something i do believe in and they are finding out new things about the universe all the time.
