13.7 Billion Years Ago....... In a millionth of a millionth of a millionth of a millionth of a millionth of a millionth of a second the universe was formed. A small piece of energy, smaller than an atom grew to the size bigger than a galaxy.. Everything that will ever exist and everything that will ever happen was formed in that fraction of a second. http://en.wikipedia.org/wiki/Big_Bang 4.5 Billion Years Ago...... An object the size of Mars smashes into the Earth at 25,000 miles per hour and was mostly swallowed up by the Earth. Within a year, gravity gathers the molten debris to form the Moon, critical to provide us with seasons. History Of The Earth http://en.wikipedia.org/wiki/History_of_the_Earth 2.5 Billion Years Ago....... Each one of us has more living bacteria inside than there are people on the Earth. Bacteria was here long before humans, animals.. Bacteria learnt how to consume the energy from the sun producing the most important waste product - Oxygen As they say....... The rest is history.
Not sure there is a better idea about. Look how late man appears on the scene (hominids). http://en.m.wikipedia.org/wiki/Hist...le:Geologic_Clock_with_events_and_periods.svg But....who set it all up? That is the question.
For accuracy it is important to note that the initial vasttly faster than light expansion resulted in the cosmic particle expanding from a point of zero length, width and height and zero time to something the size of a football, not a galaxy, it was at that point that the initial field fractured into the more commonly known fields we see today, i.e. the Strong, Weak, Electromagnetic and Gravitational fields. So where did it come from? There is a concept known as the virtual field, we know it exists we can see particles popping out of nowhere and vanishing back to nowhere in experiment, all you need is a strong electromagnet and you can separate a virtual photon into and electron and positron, a particle of light into particles of matter, this is something that happens all the time and is measurable. Probability shows us that via the quantum view of reality that there is a finite probability that very very very unlikely events will occur, for example the creation of a VAST amount of energy at a single point, we call these singularities, yes the same as black holes, but in this context it is a white hole and we live inside it. This experience of 'being' that hopefully we all agree we have, is the result of an incredibly rare event that allowed an enormous amount of energy to appear from nowhere in a kind of crystallised form, like a perfect crystal (I am being metaphoric here) that perfection fractured into the fields we know today via expansion, that is why there is the search for a Unified field theory, a point where everything in our observable universe is crushed back into something the size of a Planck length, a special length which is the smallest quantum measure of dimension that is possible, 1.61619926 × 10-35 metres. TIME, what is it, who knows, but it did not exist at the point that VAST energy point came into existence, as the point expanded, and after it reached the football size, and had cooled a bit, gravity, electromagnetism and the forces that keep the nucleus of atoms together (the strong force) and that also provide a way for nuclei to decay (the weak force) came into effect. Ok TIME and SPACE did not exist for the point, but when it was a point and as it fractured time and space came into being that was the beginning of TIME, that was about 13.7 billion years ago. That point contained everything and I mean every single bit of energy that we see here and now today, really, absolutely all the energy we can see. Please understand we are trapped in the concept of time, because time came into existence with the birth of our universe, we cannot perceive our world without the notion of time, but at a point, that singularity, did not exist, it appeared due to a quantum fluctuation, or maybe in human terms..... luck. There is much much more to be discussed on this subject, the above is a tiny tiny tiny little bit of modern thought, when you get into information theory and number theory then you start to get close to reality, and at that level modern ideas will blow all the tiny ideas we all have to dust. Look up Graham's number
Yeah........... Didn't you..?? http://www.british-filipino.com/index.php?threads/live-long-and-prosper.10182/
Thank you Jim (oss) for your reply. Interesting to read that after the "Big Bang", Supernovas (exploding stars) created uranium, gold, copper, tin, zinc and others. Over 8 Billion years, exploding stars and other stars are formed making the elements until the third rock from the Sun was made.
Yes Fred Hoyle a British theorist worked out the process of nucleosynthesis by which stars burn (fuse) heavier and heavier elements until it hits Iron, Cobalt and Nickel, Iron is poison to a star, it can fuse, but the fusion requires energy it does not release surplus energy, at a certain point in the lifetime of very very large stars when enough Iron has been produced, stars lose the ability to support their own mass and a catastrophic collapse occurs in the core of the star, it is in those moments that all the elements heavier than Nickel are made, the collapse of the core results in a shockwave and explosive bounce which blows the star apart and releases some that material. There are still some modelling issues with this idea but there are several other candidate events that should produce the kind of relative proportions of neutron rich matter that we see in the universe, such as two neutron stars colliding and decompressing some of their Neutronium.
The molten earth starts cooling and for millions of years it rained, rained and rained........ Billions of years dwarf millions of years but millions of years is a looooong time. ---------- Just lost some text..... It was a question for oss. If oxygen released by bacteria reacted with iron to form rust that fell onto the sea bed (that later gave us our land mass), how did the iron form our core? Was it gravity that pulled it to the centre?
I was hoping that this thread did not degenerate into one that was recently closed. There are no unproven theories on here.....at the moment. Perhaps this thread can be a science-based one; things that very intelligent people have worked on to indicate how evolution has led us here to where we are now.
The solar system was formed from a cloud of gas and dust, that dust contained Iron and all the other materials that we see around us, those materials elements were manufactured in stars long before the dust and gas cloud formed, the death of the supernovas created the cloud of stuff that condensed to form our solar system and the earth condensed out of the same mix of materials. So when the earth was molten like any liquid the heavy stuff sank to the middle so the centre of the earth contains a lot of Iron Nickel and a fair bit of the much heavier elements like Uranium, the iron in the crust comes from the mantle and volcanic activity, the process of accretion that built up the earth was not a perfect one not all the iron sank to the core and you have to remember that there is a lot of convection in the interior of the earth stuff gets churned around and brought to the surface on a regular basis. So yes on the surface there was plenty of iron and cyanobacteria did create the oxygen that weathered iron deposits during the great oxygenation event and created the iron ore deposits that we mine today, but this is totally separate from the events that led to the creation of the iron in the first place.
But then some people belive in science and some people belive in religion. And most of the filipinos are catholics so they will belive in what their catholic holy bible says.
