Time after the big bang


The Big Bang
10-35 seconds
The universe begins with a cataclysm that generates space and time, as well as all the matter and energy the universe will ever hold. For an incomprehensibly small fraction of a second, the universe is an infinitely dense, hot fireball. The prevailing theory describes a peculiar form of energy that can suddenly push out the fabric of space. On a rare occasion, a runaway process called "Inflation" can cause a vast expansion of space filled with this energy. The inflationary expansion is stopped only when this energy is transformed into matter and energy as we know it.

Years before the Present

Birth of the Sun
5 Bllion Years Before the Present (BP)
The sun forms within a cloud of gas in a spiral arm of the Milky Way Galaxy. A vast disk of gas and debris that swirls around this new star gives birth to planets, moons, and asteroids . Earth is the third planet out

AD

Homo Sapiens Evolve
600,000 Years BP
Our earliest ancestors evolve in Africa from a line of creatures that descended from apes.

Crab Supernova Appears
1054 A.D.
A new star in the constellation Taurus outshines Venus. Chinese, Japanese, and Native American observers record the appearance of a supernova (image at left). It is not, however, recorded in Europe, most likely as a consequence of lack of study of nature during the Dark Ages. The remnants of this explosion are visible today as the Crab Nebula. Within the nebula, astronomers have found a pulsar, the ultra-dense remains of a star that blew up.

Big Bang Confirmed
1990 A.D.
Astronomers use the new Cosmic Background Explorer satellite (COBE) to take a detailed spectrum of the microwave background radiation. These studies showed that the radiation is in nearly perfect agreement with the Big Bang theory. Two years later, scientists used the same instrument to discover minute variations in the background radiation: the earliest known evidence of structure in the universe.

The Future

The Stellar Era Ends
100 Trillion Years in the Future
Astronomers assume that the universe will gradually wither away, provided it keeps on expanding and does not recollapse under the pull of its own gravity. During the Stelliferous Era, from 10,000 years to 100 trillion years after the Big Bang, most of the energy generated by the universe is in the form of stars burning hydrogen and other elements in their cores.

The Dark Era
Times Later than 10100 Years in the Future
At this late time, protons have decayed and black holes have evaporated.Only the waste products from these processes remain: mostly photons of colossal wavelength, neutrinos, electrons, and positrons. For all intents and purposes, the universe as we know it has dissipated.

I believe that most of this is correct, except I am not too sure we evolved from apes, considering there are still apes around. You would think that if apes evolved into something better, that all of them would. They also don't know what 'Cataylst' started the big bang theory, which would be interesting to know. There are some holes in this theory, much like newtons law of gravity, so who knows maybe there is more to it than what we think? I Also think the world will end a lot sooner than what predicted because of all the polution and what we are doing to the environment. Any opinions?

whoa

whoa

I'll second that.

Not sure I can wait around that long for the dark era (whatver 10 trillion x 100 is)

I Also think the world will end a lot sooner than what predicted because of all the polution and what we are doing to the environment. Any opinions?

I also wonder why there are still apes around. Maybe it has something to do with the areas where the apes of thousands of years ago lived. Some stayed in the forests and jungles, while others moved away, or had to move away because natural disasters. Also why are the crocs and alligators still the same as they were. They are the oldest creatures on the planet aren't they?

I'm no expert so I'll let someone else figure that out.

As for the global warming, I read years ago that the world heats up prior to an ice age, and the planet is actually overdue an ice age. Now, I was a bit younger at the time, so may have misinterpreted it. I'm not disputing global warming in any way, but if what I read is true, then maybe pollution is just adding to the inevitable?
Can anyone confirm or correct me on this?

Very good diagrams and explantion. I didn't realise that scientists could actually pinpoint the events of the big bang in terms of the first few seconds, although i suppose that derives from experiments and witnessing other events in space. The power of the big bang must have been immense, as the heat and microwaves from it can still be detected today, can they not?

one question i have about the BB and evolution, is that why did an advanced race such as humans not build up certain immunities?

cancer and various other diseases kill countless humans each year, so why did humans not grow immune to them?

you would think that over hundreds of thousands of years we would be immune from certain diseases, considering humans radically evolved into what they are today.

humans are also much weaker than primates. it seems the only major change from human to primate was brain capacity. why would we lose favorable traits? such as strengh?

if we evolved from an ocean, then to land, and to what we are today, why wouldn't be able to have the favorable traits that other animals have?

is the theory of evolution a conscious being that picks and choses what we keep, and what we don't keep?

[Zaus]

Its an abstract form of the second law of thermodynamics that comes into play during evolution. If we were big,strong, and had the brain capacity that we do it would require the body to use a hell of alot more energy. Which means we would have to eat alot more, and possibly disrupt the harmony of nature. Brain capacity was more than enough to screw up the planet, what do you think would happen if we were as big as elephants?!? We dont have immunities to cancer because cancer is just a lack of certain vitamins and minerals, when you go for sixty years with only a fraction of the minerals you need to balance out your system deficiencies develop in the form of disease.

Ahh, time for a cigarette.

[seeking]

the reason we still have apes around is because we developed from a now extinct species of ape, we are but one species gone astray

[convert-proof]

i am urious about the black hole era. also the dark era. though, that will be in a looooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooong time!

we have built up immunities to hundreds if not thousands of diseases, viruses and bacteria. Its just that we have only recently (relatively speaking) extended the life expectancy of 'man' so we deal with new problems/diseases that we did not live long enough to experience before. Over time (long time) our bodies would build up the right defences but we are an impatient race Also, the industrial revolution brought with it a whole new can of worms - smog, pollution etc etc new diseases

Also viruses (due to their fast reproduction and lifetimes) mutate and change often - unlike our defences.

We will build up defences over time but the problems we're dealing with (and new ones pop up every day) are relatively new (in relation to the entire evolution of man).

[Undefined_innocence]

our bodies would build up the right defences but we are an impatient race <<<<<<<<

Not impatient. Just head strong on survival.

[ai_guardian]

Perhaps not impatient. Nevertheless, we (as a race) have taken it upon ourselves to 'play' god in many respects (justice, survival etc.) when NATURE would have done so EVEN BETTER through 'survival of the fittest'.

I do not mean to offend anyone, this is not directed @ anyone, so please do not get offended. Since we clearly promote survival of the weakest (those that would not be fit to survive without our intervention ie. medicine, protection, safety, aged care) our race is built like a house-of-cards so to speak. Many weaknesses and many diseases will come back to haunt us. We are very good at masking our weaknesses though

Am I the only one that still believes in God? I mean its obvious... the fact you are reading what I am typing shows something CREATED us and we werent just a bang~~ what caused the bang if so, there is still always a stronger power even star wars nerds believe in the force.... Do not be ignorant in these last days...

Have you ever thought there is evidence supporting the fact it has happened? much more credulous facts and solid evidence, whereas religion cannot be proved either way. Maybe you should further your research in religion (not just one but all of them) and science, then see who's ignorant here.

I believe in God.

However, this theory is compatible with the creation. (at least in my opinion.)

Have you asked yourself what created this huge mass to begin with?

Yes I have, lol. Of course the answer to that is still a mystery.
But with how elegant the universe really is, there would be no
need for a God, because most things created could be explained
without the use of God.
