Every atom in your body is billions of years old. Hydrogen, the most common element in the universe and a major feature of your body, was produced in the big bang 13.7bn years ago. Heavier atoms such as carbon and oxygen were forged in stars between 7bn and 12bn years ago, and blasted across space when the stars exploded. Some of these explosions were so powerful that they also produced the elements heavier than iron, which stars can't construct. This means that the components of your body are truly ancient: you are stardust.
One of the mysteries of science is how something as apparently solid and straightforward as your body can be made of strangely behaving quantum particles such as atoms and their constituents. If you ask most people to draw a picture of one of the atoms in their bodies, they will produce something like a miniature solar system, with a nucleus as the sun and electrons whizzing round like planets. This was, indeed, an early model of the atom, but it was realised that such atoms would collapse in an instant. This is because electrons have an electrical charge and accelerating a charged particle, which is necessary to keep it in orbit, would make it give off energy in the form of light, leaving the electron spiralling into the nucleus.

The atoms in your seed have been doing the rounds for a long time.

All human cells are less than 15 years old irrespective of the persons age, so your eyes are no older than 15 years old, but the degenerative DNA just makes them worse eachtime

Yes, the cells that we where born with have left our body, we are literally different people from who we where, physically.
Cells are made up of atoms, atoms can not be created without fusion such as the big bang and exploding stars. Our bodies do not generate new atoms,those atoms have been here for billions of years.

''we are literally different people from who we where'', mentally also.
Every atom in your body is Billions of years old.
Did you know that every atom is only made up of electrons protons and sometimes neutrons, therefore everything we know of are only made from these particles.

Did you know that the nucleus of the atom which is the core matter, is so amall that the equivalent is a flee being in the centre of a cathedral.
The rest is basically empty space. So when we touch something we believe to be solid it is really nothing more than empty space
.
It`s all energy.

Did you know that if you hit one cathedral with another - they are sure as hell damn solid enough for empty spaces, and the flee gets an Ed.ache!
If you took out all the space between the elements that make up all the atoms of every human that's ever lived then the total physical matter left wouldn't even be the size of a sugar cube
What I want to know is what happens at the point quantum theory becomes the theory of relativity.
I.e. At what size do the laws of science change that govern the elements that make up large things?
There might be a 'zone' where no rules apply at all.

When one solid object( as we perceive them) collide it is merely a meeting of energies Ivor.
The electrons flying around the outer shell of the atom are sending out a negative charge which is why we feel resistance for example when you press your thumb onto your laptop it is two repelling energy fields and nothing is really solid. It is an illusion.

I agree Dusty, quantum exploration may lean to a holographic reality, well it is already.
I like this thread already. The good Lord works in mysterious ways doesn`t he
I would like to add that everything you see on this planet today and every day is made of stardust.
And just for an added twist, if you could cut a piece out of a black hole, the size of an oxo cube, it would weigh more than the biggest aircraft carrier that the US navy has.

I think I got those two from Stephen Hawking's book "A Brief History of Time". Having said that, it was heavy going, but what I could understand opened my eyes.
Of course the consensus of scientific opinion is that some 95.1% of the universe is made up of a mysterious 'dark matter' & 'dark energy'. Dark matter neither absorbs nor reflects light, has never been isolated, and is purely hypothetical, but is needed to explain the gravitational effects necessary to account for the large scale structure of the universe. Dark matter is not made from baryons as normal matter protons & neutrons.
It helps to demonstrate how little we know about the universe when 95% of it cant yet be explained.
Scientists simply don't know what DM is made of.

One million, million, million, million, millionth of a second after the Big Bang the Universe was the size of a …pea.
There are another three crackers from the book that I remember vaguely, however I don't have the book now so I will post them tomorrow after giving it some thought as to explain them properly.
I will give you a clue however. In theory, it may be able to read this post again in several billion years time!

There are 60,000 miles of blood vessels in the human body.

Speaking about the Big Bang, not one scientific brain has come up with a theory as to what happened before the Big Bang. This is the point where physics breaks down and remains the Holy Grail of all science community.
Of course the big bang theory is just that a theory.
Was the big band supposedly created by chemicals exploding?
when does the implode start???
Nobody knows, but according to Hawking it is possible, known as the Big Crunch.

everything has an equal and opposite reaction....its gonna happen if everything they tell us is true
...perhaps the black hole tears through the fabric of time and space and what passes for a "big bang" is actually all the pent up energy in the black hole being released through into a new bubble of space and time??????
Actually, one of the three things I remember about Hawking's book concerns the Big Crunch. He theorises that if indeed the Big Crunch happens, eventually, we will all live our live again, only back to front. ie.

Mishap there. ie. we will be old first then go back inside the womb, etc. etc. (hard to imagine, I know)

Interesting point come to think about it. Hawking also theorises that if you fell in to a black hole, (you would be dead btw) and survived to come out the other end, you would end up in another universe.
Many scientists believe there are multiple universes.

If you thought about it long enough egner, you could end up being sectioned! As a wise man once said...."Life's meant to be lived, not understood".

you may be right stewartyb....
but if we never tried to understand our surroundings we may still think thunder and lightening was a sign from the gods!!!

A point of singularity egner.
However we are only trying to conceive these possibilities with slightly sophisticated monkey brains, what chance do we have. Einstein was a freak.

why is it not a sign from the gods...just because we have a perception of the physical reasons for the happening???
Einstein said that if he could have one wish granted it would be to ride on a beam of light. Can you imagine the fun he would have had proving that there are more stars in the universe than grains of sand on the earth.
a man has been hit 7 times by lightening....what does he think of god?????
Not sure what he thought of God, shuck..
But he ended up shooting his brains out over the love of a woman when he was 71. Roy Sullivan was his name.
Now his atoms which gave him animation are now on another journey.

If Einstein were to have ridden at the speed of light he wouldn't have seen anything since we only see things when light is reflected, it would never arrive would it?
Albert too busy thinking about the colour of Marylyn's knickers imo

What I want to know is what happens at the point quantum theory becomes the theory of relativity.
I.e. At what size do the laws of science change that govern the elements that make up large things?
There might be a 'zone' where no rules apply at all.
I like that question.
There seems to be no point at which quantum effects stop and classical ones take over, not like the shifting of gears anyway.
The strange things you hear about (multiple positions, spins, polarities etc) for single particles occur when they do not encounter other particles and fields. When they do encounter them, the interaction very quickly collapses those multiple states into a single state – a single dot of an electron on a screen in one place for example.
In the real world there are particles and fields everywhere, so these interactions are the norm and so strange quantum states do not persist beyond the unimaginably smallest fraction of a second. If they did everything would be a blur, as all matter would exist in a perceptible and confusing soup of alternatives positions.
But these alternate states do not entirely disappear. They are still here in the ‘real’ world, but on a scale that is again imperceptibly small. They lose coherence.
So, in short:
Quantum effects are easier to maintain in isolated small amounts of particles.
But they quickly lose their strange properties if they encounter other particles.
Large complicated objects (compared to a simple molecule) like a grain of sand, are in a single state because there are billions of particle interactions going on.
So the world of familiar large things takes no real time at all to emerge out of the quantum world of multiple states. Blink of an eye.
Yet, the other quantum states don’t just vanish, they persist but in aWhat I want to know is what happens at the point quantum theory becomes the theory of relativity.

You almost pulled that off as your own work flowermyth.
You are forgiven, interesting post.

Another interesting fact (not a theory) is that you can look deep into the universe and see a star with a telescope that doesn't exist anymore. The star exploded millions, if not billions of years ago. What you are seeing is the light from the now defuct star still visible as it takes so long to reach us.
Light travels at approximately 670 million miles an hour
Or exactly 299,792,458 metres per second.
The furthest star is named Deneb which we can see with the naked eye is around 1550 light years away from Earth. It is also in the top 20 brightest stars in the sky which makes it easy to see.

I don't personally believe in the start of time (big bang etc). I think people need one to help them comprehend how everything came together, but, as has been mentioned earlier on the thread...where did the energy come from that created the big bang?
I think in all probability, history has an infinite time, and so will the future. I;d be surprised if planets haven't existed an infinite number of years. IE they have always been around, and little has changed in the history of time.

Latest estimates are that there are 400 billion stars in every one of over 400 billion galaxy's in the universe.
If 1000 grains of sand can fit into 1 cubic cm then 1cubic m=10 million grains of sand.
If the average visible beach is 20m wide and 10m deep then 1 km of beach =2000billion grains of sand.
If there is 1million km of coastline on earth then there are 2 billion billion grains of sand.
Therefore 1 grain of sand represents 80,000 stars.More than you can see in the visible sky on a clear night.
I Think I got the maths right.

Light?
I prefer to use miles per second, easier to work with 186,282 mps in a vacuum.
Of course light doesn't actually exist until hit hits something, the retina in your eye, the moon, the atmosphere. You can't see it passing through space.
We should not assume that other life in the universe would see light in the same way as we do. The life forms on Earth see light relative to us.
Other beings elsewhere may see it at a different speed, at a different frequency in the electromagnetic radiation spectrum & in a different way.

Very true NLad, it`s not a given that other biological creatures beyond earth would pick information up on the same frequency as us. The way we see colours for example is only our minds interpretation of that particular vibration. In fact it`s quite easy for surgery to re-wire the parts of the brain for someone to see the colour green as blue or the colour red as a a vibrating yellow for example.
