Initial thought provoked |
| trillions of atoms create you |
"I" don't really exist.... nor does
"anything" - Everything and anything "I" perceive, is only a perception - made
by an "I" that doesn't exist - therefore the perception doesn't exist. |
| atoms are mindless particles, and
not even alive. |
| A long
human life adds up to about 650,000 hours. |
Just a good figure to "note" |
|
your atoms will close you down, then go off to be other things |
..re-incarnation?? But not as we've been brought
up to believe.... |
| life =
carbon, hydrogen, oxygen and nitrogen, calcium, sulphur, some other very
ordinary elements | I'd always thought
"I" was just a collection of chemicals and electricity... a lucky coincidence -
this tends to confirm that bright idea. |
|
Atoms make everything.....water ...air... rocks.... stars....
planets...... distant gassy clouds... swirling nebulae... |
If atoms make everything.... what makes the bits
in-between atoms...?? Also, what made the atoms? |
| No rule or law requires the universe to fill
itself with small particles of matter or to produce light and gravity and the
other properties on which our existence hinges. There needn't actually be a
universe at all. For a very long time there wasn't. There were no atoms and no
universe for them to float about in. There was nothing - nothing at all
anywhere. | Is there just 1 Universe??
Or, many?? And if there was "nothing" does that mean there was no "time", no
universe (s)?? |
| Of the
billions and billions of species of living things that have existed since the
dawn of time, most - 99.99 per cent are no longer around. Life on earth is.....
not only brief but very tenuous. | So,
it is "natural" for species to come into existence, and go. |
| Protons are so small that a little dib of ink
like the dot on this 'i' can hold something in the region of 500,000,000,000 of
them. | Can I think that small?? |
| shrink a proton down to a billionth of
its normal size...... pack into that tiny, tiny space about an ounce of matter -
to build an inflationary universe.... instead - to build a more old-fashioned,
standard Big Bang universe.......gather up everything there is - every last mote
and particle of matter between here and the edge of creation - and squeeze it
into a spot so infinitesimally compact that it has no dimensions at all. It is
known as a singularity. In either case get ready for a really big bang. |
How to make a (our) Universe |
| Outside the singularity there is no
"where". Time doesn't exist. There is no past for it to emerge from. |
| In three minutes, 98 per cent of all the
matter there is or will ever be has been produced. We have a universe. |
| ago... 13.7 billion years |
the currently calculated age of our universe |
| the inflation theory......gravity
emerged.... joined by electromagnetism and the strong and weak nuclear
forces...later... elementary particles.... our universe... a hundred billion
light years across...created in one million million million million millionths
of a second | size and length of time
needed to create it |
| ..there
may be many universes...each with different attributes......and we simply live
in one that combines things in the way that allows us to exist. |
so other universes may exist - but maybe in
different dimensions - e.g. time or some other unimaginable dimension... |
| ...you can never get to the edge of the
universe...... you would come back to where you began.... the universe
bends,.... space curves, in a way that allows it to be boundless but infinite.
Space cannot properly be said to be expanding.......solar systems and galaxies
are not expanding, and space itself is not expanding. Rather galaxies are
rushing apart | Don't understand the
'bending/curving' bit - but galaxies etc... rushing apart into the void can
understand |
| ..there is no
place where you can find the edge of the universe, so there is no place where
you can stand at the centre of the universe. ... For us, the universe goes only
as far as light has traveled in the billions of years since the universe was
formed. This visible universe.... is a million million million million miles
across. ... the meta-universe is vastly roomier still..... the number of light
years to the edge of this larger, unseen universe would be written not with 10
zeros, not even with 100, but with millions. |
Visible and meta-universes - sizes. |
| About 4.6 billion years ago, a great swirl of gas
and dust some 24 billion kilometres across accumulated in space where we are now
and began to aggregate. Virtually all of it - 99.9 per cent of the mass of the
solar system - went to make the Sun. Out of the floating material that was left
over, two microscopic grains floated close enough together to be joined by
electrostatic forces. This was the moment of conception for our planet. |
Birth of our Sun, planets and Earth |
| In just 200 million years, possibly
less, the Earth was essentially formed. |
Earth forming took... |
|
.. about 4.4 billion years ago, an object the size of Mars
crashed into Earth.... to form a companion sphere, the Moon... within a year it
had formed. Most of the lunar material, it is thought, came from the Earth's
crust... | Birth of the Moon and its
forming.. |
| ...the ....distance
from the Earth to the Sun...is 149.597870691 million kilometres. |
I always remember it as 93 million miles. |
| ...the Earth's weight is 5.9725 billion
trillion tonnes | Earth's weight.. |
| ...chemicals....the number of protons in
their nuclei.. is known as their atomic number.... atomic weight...is the number
of protons plus the number of neutrons in a given element. |
Atomic weight & number |
| ...the rocks were converting mass into
energy..... Marie Curie dubbed the effect 'radioactivity'. |
so that's what it is.... |
| ...energy is not a continuous thing like flowing
water but comes in individualised packets, which are called quanta. |
Energy doesn't "flow" |
| E stands for energy, m for mass and c2
for the speed of light squared. | E = mc2 |
| .. energy is liberated matter; matter is
energy waiting to happen..........if you are an average-sized adult you will
contain no less than 7 * 1018 joules of potential energy - enough to
explode with the force of thirty very large hydrogen bombs,....
Everything has this kind of energy trapped within it. We're just
not very good at getting it out. Even a uranium bomb - the most energetic thing
we have produced yet - releases less than 1 per cent of the energy it could
release...
Einstein's theory explained how radiation worked... by
converting mass to energy extremely efficiently.... |
Energy...... |
|
...the speed of light was constant and supreme. Nothing could overtake it. |
But surely that's not right....?? |
| Relativity says that space and time are
not absolute, but relative both to the observer and to the thing being observed,
and the faster one moves the more pronounced these effects become. e.g. annoying
music elsewhere - if we move it appears quieter (it's not - but that's how it
appears to us). | So when we say
"relatively speaking" or "he's my relative" - everything is relative - so we're
speaking correctly!! |
| Gravity
is a product of the bending of spacetime |
and gravity does not really exist - rather, what moves planets
etc.. is the distortion of space and time. |
|
There may be 140 billion galaxies in the visible universe |
In 1919 only one was known of... the Milky Way. |
| The universe is expanding in all
directions - at an unexpectedly increasing speed |
but objects within the galaxies are not - what's causing the
speed-up?? |
| An atom can
survive possibly 1035 years |
And its size is one ten-millionth of a millimetre |
| An atom is - protons (positive charge),
electrons (negative), neutrons (no charge) |
Protons and neutrons are inside the nucleus, whilst electrons
spin around it like the blades of a fan. |
|
The nucleus is one-millionth of a billionth of the volume of the
atom | Atoms are mostly empty space |
| Electrons don't fall into the nucleus
because they occupy only certain well-defined orbits |
They can move from one orbit to another, but they just disappear
from one and instantly appear in the other - without visiting the space in
between.- - the quantum leap!! |
|
Fission is the firing of neutrons into the nucleus |
|
| Quantum
mechanics states... | The electron is a
particle which can be described in terms of waves. We can know its path through
space or where it is - but never both |
|
Things on a small scale behave nothing like things on a large
scale | matter can pop into existence
from nothing at all - provided - it disappears again equally quickly |
| Certain pairs of sub-atomic particles
(even separated by big distances) each can instantly "know" what the other is
doing. | e.g. the theory said... spin a
particle in one direction - and immediately its pair will spin in the opposite
direction at the same rate! |
|
This was proven in 1997.... | when
photons were sent 7 miles in opposite directions and each instantly reacted
oppositely to what happened to the other. This is a
violation of the Special Theory of Relativity - nothing can outrace the speed of
light - but at the sub-atomic level... information could!! |
| The strong nuclear force binds atoms together.
The weak nuclear force controls rates of decay etc.. |
The weak force is ten billion billion billion times stronger than
gravity, and the strong force is stronger still - but their grip reaches only
one hundred thousandth the diameter of an atom. |
| Igneous rocks are created through heating |
Sedimentary rocks through laying down of
sediments. |
| Earth's
age....4,550 million years | plus or
minus 70 million. |
| Particles
can come into being and are gone again in 0.000000000000000000000001 of a second |
10 thousand trillion trillion neutrinos hit (and
pass straight through) the Earth every second |
| There are (today) 150 known particles |
With another 100 suspected. |
| 90 to 99 percent of the known universe is
composed of "dark matter" | |
| Asteroids orbit between Mars and Jupiter |
Each will be about half a million kilometres from
its neighbour. |
| Each year the
Earth grows by... | 30,000 tonnes of
space-dust |
| From the surface
of the Earth to the middle..... | is
6,370 kilometres. |
| At the
centre - everything is weightless |
Because all the gravity is above and around - not "below" it. |
| The Moon and Mars (bodies that don't have a
liquid core) do not have magnetism |
Remember that... |
| The Earth's magnetic field reverses itself
every 500,000 years or so | and there's
no real understanding.. why?? |
|
Magnetism is vital in keeping us alive |
Protecting us from harmful cosmic rays |
| The Mount St Helens eruption was
equivalent to 500 Hiroshima sized bombs.. |
and the hot cloud raced out at 1,050 kilometres per hour. |
| Yellowstone National Park is the largest
active volcano in the world.. | If Mount
St Helens was a pea, then Krakatoa was a golf ball and Yellowstone will be a
sphere 6 feet in diameter!! |
|
400 million years ago.... | We crawled
out of the sea... |
| We (humans)
can live on only 12 per cent of the total land mass |
And only 4 per cent of the whole surface |
| If the Earth were perfectly smooth... |
it would be covered by water - everywhere - to a
depth of 4 kilometres!! |
| If
the Moon were not there...... | The
Earth would wobble |
| The Moon
is receding from us (Earth) | At 4
centimetres per year - in 2 billion years - Earth will start to wobble! |
| There are 92 naturally occuring element
on the Earth. | Of every 200 atoms in
our bodies - 126 are hydrogen, 51 oxygen, 19 are carbon |
| The Earth appears accommodating.... |
Because we evolved to suit it |
| The atmosphere... |
Without it - the Earth would be a ball of ice with an average
temperature of -50C. It extends upwards for 190 Kilometres. |
| At any one time... |
1,800 thunderstorms are in progress - 40,000 per day. |
| Air flows from... |
high to low pressure areas |
| The Earth revolves at.... |
1,675 kilometres per hour at the Equator - less
elsewhere.. |
| Clouds.... |
Stratus (layered), Cumulus (fluffy), Cirrus (high
- thin), Nimbus (rain) |
| 0.035
of the Earth's fresh water... | Is
floating around in clouds. |
|
Water molecules.... | If they land:
 | in fertile soil, will be re-evapourated within hours or days |
 | into groundwater - maybe thousands of years |
A lake consists of water molecules that have been there around
10 years.
Ocean water - 100 years. |
|
The Atlantic is saltier than the Pacific |
|
| It takes
1,500 years for water to travel from the North Atlantic to the Mid-Pacific |
|
| A potato is
80 per cent water.. | A cow is 74%,
bacterium is 75%, tomato is 95%, human is 65%. |
| Without water - a human... |
in a couple of days - the lips vanish, gums
blacken, the nose withers to half its length, skin around the eyes shrinks and
prevents blinking. |
| Sea water
contains.. | 70 times more salt than we
can metabolise... we sweat and cry sea-water. |
| There are 1.3 billion cubic kilometres of water
on the Earth... | Its been there for 3.8
billion years. |
| 97% of all
water is in the seas | Pacific 52%,
Atlantic 24%, Indian 21% |
|
Fresh Water (3% of total)... | most of
it is in ice-sheets - 90% of ice is in Antarctica (2 miles deep) - at the North
Pole its only 15 feet deep. |
|
Mariana Trench... | Is 10,918 metres
deep. |
| Organisms living in and
around deep-sea vents.... | A type of
worm - where the water temp was 78C warmer at their heads than their tails |
| Ocean waters don't get more salty with
time because.... | The vents act like
filetrs. |
| 55 gallon drums
filled with radio-active material have been dumped (since 1946) off the
Fallarone Islands (near San Francisco)... |
When they failed to sink - navy gunners fired at them to let
water in....... etc.... |
| There
may be 1,000,000 types of protein in the human body |
Proteins shouldn't exist..... they cannot exist
without DNA and DNA has no purpose without proteins... which came first?? DNA or
Proteins?? |
| We shed 10 billion
flakes of skin every day | Eeeeeehh... |
| Most of what has lived on Earth has left behind
no record.. | Will we...?? |
| Life on Earth goes extinct - quite
regularly | Oh no!! |
| Plants started land-colonisation about 450
million years ago | Remember that
date..... |
| An isotope is an atom with an abnormal number of
neutrons | Worth remembering!! |
| There isn't any bit of us - that was
part of us 9 years ago | What?? Not even
my old.... |
| Humans have 46
chromosomes - potatoes have 48!! |
Surely it goes up if you eat chips..?? |
|
Most of the people you see are relatives |
I hope not!! |
|
There is as much as 20 million Kms of DNA inside each of us |
More if you're fat?? |
| DNA is not alive |
And was discovered in 1869 |
| 97% of our DNA is "junk" |
And Genes are only instructions to make proteins |
| The purpose of life is.... |
To perpetuate DNA |
| Humans have 35,000 to 40,000 genes |
Same as is found in grass |
| All finished... but aren't we "thinking"
now......?? | |
