In 1973, Edward
Tyron proposed
that the
Universe is a
result of a
vacuum
fluctuation. The
main difficulty
of this proposal
is that the
probability that
a 13.7 billion
year old
Universe could
arise from this
mechanism is
extremely small.
In addition,
physicists would
question Tyron's
starting point:
if the Universe
was born from
empty space,
then where did
the empty space
come from? (Note
that from the
point of view of
general
relativity,
empty space is
unambiguously
something, since
space is not a
passive
background, but
instead a
flexible medium
that can bend,
twist and flex.)
In 1982,
Alexander
Vilenkin
proposed an
extension of
Tyron's idea and
suggested that
the Universe was
created by
quantum
processes
starting from
"literally
nothing",
meaning not only
the absence of
matter, but the
absence of space
and time as
well. Vilenkin
took the idea of
quantum
tunneling and
proposed that
the Universe
started in the
totally empty
geometry and
then made a
quantum
tunneling
transition to a
non-empty state
(subatomic in
size), which
through
inflation (the
Universe expands
exponentially
fast for a brief
period of time
which causes its
size to increase
dramatically)
came to its
current size.
Another idea
is from Stephen
Hawking and
James Hartle.
Hawking proposed
a description of
the Universe in
its entirety,
viewed as a
self-contained
entity, with no
reference to
anything that
might have come
before it. The
description is
timeless, in the
sense that one
set of equations
delineates the
Universe for all
time. As one
looks to earlier
and earlier
times, one finds
that the model
Universe is not
eternal, but
there is no
creation event
either. Instead,
at times of the
order of 10-43
seconds, the
approximation of
a classical
description of
space and time
breaks down
completely, with
the whole
picture
dissolving into
quantum
ambiguity. In
Hawking's words,
the Universe
"would neither
be created nor
destroyed. It
would just BE."
The "It's
a meaningless
questions
explanation" --
If the universe
is everything,
then there could
not have been
anything that
caused it;
"Look, while it
may make sense
to ask what
caused this
chair, it surely
does not make
sense to ask
what caused the
universe as a
whole to exist.
It seems to me
that to ask for
the cause of
something is to
ask what other
thing within
the universe
brought it
about. That is
how the game of
asking for and
giving causes is
played out. When
I ask, for
example, what
caused that tree
outside the
window to exist,
I am asking for
you to identify
some other thing
or event
within the
universe that
brought that
tree into
existence. But
if to ask for
the cause of
something is to
ask what other
thing within
the universe
brought it
about, then
it cannot make
sense to ask
what is the
cause of the
universe as a
whole. That
would be to
pursue the
question of
causes outside
the context in
which such
questions can
meaningfully be
raised. For
example, it
makes sense to
ask what is
north of
Scotland:
Iceland. What is
north of
Iceland? The
Arctic Circle.
What is north of
the Arctic
Circle? The
North Pole. And
what is north of
the North Pole?
The question
simply does not
make sense."
What did the

man who ever

life?

Question
Given the First
Law of
Thermodynamics:
that you can't
get something
from nothing.
Where did all
the stuff in the
universe come
from and how is
it still a law
if it was once
broken?
Asked by: Rob
Answer
The law you
cite, applies
only to 'closed
systems', i.e.
where nothing
can be added or
subtracted from
the 'specimen'.
Obviously if you
apply the law to
an empty box,
then open the
box and dump in
a handful of
sand, or quarks,
or energy, you
don't expect the
law to apply,
because the
system is not
'closed'.
It is not known
whether the
universe as a
whole is a
closed system
now at present.
As far as
conditions
preceding and at
the very moment
of the 'big
bang', we can
only speculate
whether the
universe was
closed, or open
(to another,
larger system),
or whether the
First Law (or
lots of other
laws) even
applies under
those extreme
conditions.

In the
macroscopic
world, the
domain of
‘classical’
physics, the
laws of
thermodynamics
are, and have
always been,
true.
However, on the
quantum scale,
it is a very
different
matter.
Hiesenberg’s
uncertainty
states that
there will
always be a
level of
uncertainty when
you try to make
measurements of
particles and
other quantum
scale
occurrences. You
can never know
everything about
a particle’s
position and
motion at any
one time. This
is an intrinsic
uncertainty, it
is not due to
limitations on
our measuring
devices. This
uncertainty of
the energy of
anything of the
Planck scale is
size allows some
very bizarre
phenomena to
occur.
To us, vacuums
appear to
contain nothing
at all. But, it
you were to look
closely, very,
very closely (to
the order of
10^-35m), space
is actually a
foaming mass of
quantum
activity. This
quantum foam is
made of
particles and
micro-black
holes popping in
and out of
existence,
apparently in
contravention of
the second law
of
thermodynamics,
they appear out
of nothing with
energy, then
disappear again
just as quickly.
The key to this
is the
uncertainty
principle. The
disturbance is
permitted to
‘borrow’ a tiny
amount of energy
and exist for a
very short
length of time,
and then it must
return the
energy and
disappear again.
But, the more
energy it
borrows, the
less time it is
allowed to
exist. These
‘temporary’
particles,
called virtual
particles, are
not just
theoretical,
they have been
proven to have
real effects on
scientific
experiment.
The only thing
that prevents
these virtual
particles from
coming into
permanent
existence is a
lack of energy.
However, it is
possible to
artificially
supply energy to
the particles
therefore
promoting them
into reality.
This could be
done in a lab by
creating very
strong electric
fields, but
these fields are
very difficult
to create. On
the other hand,
intense
gravitational
fields could
also do the job.
It is possible
that during the
big bang, black
holes the size
of a nucleus
popped into
existence due to
the quantum
foam. The
interesting
thing is that
the smaller a
black hole is,
the more
strongly
space-time is
distorted around
it and
distortions in
space-time imply
the existence of
very strong
gravitational
fields. Stephen
Hawking has
shown that the
gravitational
field around
such a hole
would give
enough energy to
the quantum foam
to promote the
particles into
real existence.
Calculations
show that in the
big bang the
initial extreme
conditions would
also have been
enough to create
real particles
out of the
gravitational
energy of the
rapidly
expanding
universe.
And as for how
the universe
actually came
into being
itself, it is
believed that
also in the
quantum foam,
virtual
space-time
bubbles also
continually pop
in and out of
existence, like
virtual
particles, only
to disappear
again. However,
it is possible
that one of
these space-time
bubbles, which
is actually an
unimaginably
small universe,
could avoid
rapidly
disappearing
again and be
promoted to a
full size
universe, such
as ours.
However, for
this to work
some sort of
repulsive force
is needed, a
sort of
anti-gravity.
Many scientists
believe in the
existence of
such a force at
the time of the
creation of the
universe, but as
I’ve answered
your question
and that’s a
whole other
topic, I think
I’ll stop before
I go off on too
much of a
tangent.
To summarize,
due to the
uncertainty
principle,
particles and
space-time
bubbles
continually pop
in and out of
existence for
short times
depending on
their energy,
without breaking
the law of
conservation of
energy as they
disappear again.
Think of it like
an accountant
(the universe)
who balances the
books at the end
of every month.
If someone (a
virtual
particle) was to
borrow some
money on the 4th
day of the month
(pop into
existence) then
put it back on
the 8th day,
(disappear
again) then as
far as the
bookkeeper would
know, nothing
had gone amiss
and no rules (or
laws) had been
broken. If a
particle is to
come into
complete and
real existence,
it must take its
energy from
somewhere, such
as a
gravitational
field.

Where did the
Universe come
from?
Assuming the Big
Bang is a valid
theory of the
creation of
Earth and the
Universe, then
where did the
original mass
come from, that
formed
everything that
we see today?
First of all,
note that mass
and energy are
equivalent. So,
the total mass
of the Universe
need not be
conserved even
though the total
energy (taking
into account the
energy that is
equivalent of
the mass in the
Universe) is
conserved. Mass
and energy are
related by the
famous equation
E=mc2.
Hence if there
is enough
energy, photons
can create
matter-antimatter
pairs. This is
called pair
production and
is responsible
for the mass in
the Universe.
As to where
everything came
from, there is
no conclusive
opinion. One
idea was that
the Universe was
created from
vacuum. This is
because
according to
quantum theory,
the apparently
quiescent vacuum
is not really
empty at all.
For example, it
is possible for
an electron and
a positron (a
matter
antimatter pair)
to materialize
from the vacuum,
exist for a
brief flash of
time and then
disappear into
nothingness.
Such vacuum
fluctuations
cannot be
observed
directly as they
typically last
for only about
10-21
seconds and the
separation
between the
electron and
positron is
typically no
longer than 10-10
cm. However,
through indirect
measurements,
physicists are
convinced that
these
fluctuations are
real.
Hence, any
object in
principle might
materialize
briefly in the
vacuum. The
probability for
an object to
materialize
decreases
dramatically
with the mass
and complexity
of the object.
In 1973, Edward
Tyron proposed
that the
Universe is a
result of a
vacuum
fluctuation. The

of this proposal
is that the

Did the
Universe make
itself?
January 1998
How did the
Universe get
going? The usual
tricky question.
All the answers
are a bit messy
(see The History
of the
Universe!).
Now two
scientists have
suggested that
the Universe did
spring from
something,
rather than from
nothing - and
that something
was itself.
Come again?
Well, the
Universe was
it's on mother.
Inflation theory
predicts that
rapidly
expanding parts
of the Universe
- very early on
- could have
spawned others
of their kind:
baby universes,
'budding off
from the
Universe like
branches from a
tree.'
Well it's
possible that a
branch of
spacetime could
look back to
rejoin the main
trunk. This is
possible because
Einstein's
general theory
of relativity
permits closed
loops of time
(!). Scientists
Richard Gott III
and Li-Xin Li of
Princeton
University have
found that a
time loop could
have existed
before the Big
Bang, without
violating any
laws of physics.
Space would have
been in a loop
of time,
perpetually
recreating
itself! So every
event in the
Universe would
have an event
preceding it.
Gott and Li
also say that
this helps to
explain the
phenomenon of
'the arrow of
time'.

What is
most Philosophically
viable view?
1) The universe
is simply
infinite and
needs no
explanation of
its origin.
False: This
can't be true
because if there
had been an
infinite amount
of time to
traverse then it
would have been
impossible to
ever have gotten
to now.
In other terms:
Nothing can
actually
"realize"
infinity because
infinity is
boundless and
time itself plus
all matter and
energy would
have had to have
actually
realized
infinity
backwards in
time to have
gotten to the
present.
2) The universe
had a specific
beginning and is
finite in time.
False: This
would mean that
something came
from nothing and
that,
philosophically
speaking, is
impossible:
"If there was
ever a time
there was
absolutely
nothing there
would be nothing
now."
3) The universe
is perennial or
cyclic.
Possible: This is a
possibility
because physics
shows us that
time itself can
have a
beginning, thus
a cyclic
universe would
not need to
experience
infinity, since
time would cycle
too.
However, the
implication here
is that
everything would
happen over and
over just as
before, which
would seem
pointless and
even unfair to
those how are
handicapped, die
young, etc.
A cycling
identical
universe is
conceivable, but
would just seem
to render the
whole affair
utterly
pointless.
4) The
universe cycles
but does so in
an ever evolving
manner.
Possible, but
with problems to
consider: Since in our
experience
things evolves,
then it would be
likely that the
universe would
evolve as well
through its
successive
cycles.
Problem: If the cycling
evolutionary
process has gone
on for an
infinite amount
of times then
the evolutionary
process would
already be at
its most
possible evolved
state. The
cycle previous
to the one we
are in would
also have been
preceded by an
infinite number
of cycles, so it
too would have
been at maximum
evolution.
Paradox: if the
previous cycle
and this cycle
both represent
maximum
evolution, then
there could have
been no
evolution from
the previous to
the current
cycle. A
paradox cannot
occur, so this
scenario must be
false, unless
there is no
highest or
perfect state.
5) The universe
has not cycled
either
identically, or
evolutionary for
an infinite
number of times.
There was a
first cycle.
False: This only
leads us back to
the problem
encountered in
#2 where
something would
have had to have come
from nothing.
If the universe
exists now, it
must have always
existed in some
form.
6) The
universe cycles,
but does so in
an ever changing
fashion.
Probable: As
before, since in our
experience
things change,
then it would be
likely that the
universe would
continually
change
through its
successive
cycles.
There could be
no ultimate
state of
perfection,
since that state
would have been
already reached
through an
infinite number
of previous
cycles, as in item 4.
However, if the cycling
process simply
results in an
infinite amount
of permutations,
then
it would not
matter how many
cycle have
previously
transpired;
every cycle
would just be
different.
The general
tendency is to
go from
simplicity to
complexity, but
if such changes
had been going
on infinity, we
would already be in a
state of
infinite
complexity,
which would not
seem to be the
case.
Consequently,
the variations
would need to be
directionless,
with any type of
change possible.
7) There is an
infinite
multiplicity of
universes.
Most Likely:
This is really
not different
from the above
scenario, but
the infinite
permutations of universes would
just co-exist,
rather than be
linear. An infinite
amount of
something is not
like an infinite
amount of time,
which can't
occur.
There,
philosophically
speaking, could
be an infinite
number of things
coexisting.
This model helps
in the
understanding of
how the right
conditions could
exist to produce
us or anything
imaginable.
All of the
various
universes would
have to cycle
just as one
would, probably
each creating
various
permutation,
while
co-existing with
other
permutations.
The
universes could
be viewed
something akin
to bubbles in a
percolator - all
going round and
round, changing
into steam and
returning again
in an endless
variety of forms.
The only problem
here is that a
multiple
universe theory
means that
the other
universes
actually do
exist, so
there in fact
would be an infinite
number of
variations of us
and what we are
doing.
Though
mechanistically
and
philosophically
possible this
seems too
incredulous to
be true, but
then again could
offer an
explanation for
the phenomenon
of deja vu
which virtually
everyone
experiences..
