Scientists are starting to rethink what
they thought they knew about the
universe. Thanks to the latest
discoveries from the James Webb Space
Telescope in its new images of the
farthest regions of space, web has
revealed things that current theories
simply cannot explain. For the first
time, scientists may have found signs of
an entirely new kind of black hole,
something that challenges the
traditional Big Bang model. Web has also
uncovered record-breaking distant
galaxies that look far stranger than
expected, leaving experts puzzled. On
top of that, the telescope has spotted
many mysterious objects in huge numbers,
but no one really knows what they are.
Even more surprising, some of these
discoveries suggest that our universe
could be part of something much bigger
and stranger than we ever imagined. So,
let's explore what scientists have
actually discovered and how these
findings suggest that something may
exist beyond our universe.
The universe is far stranger than we can
imagine. In fact, most of it is fading
beyond our reach forever. We live inside
what scientists call the observable
universe. Think of it as a cosmic bubble
around us. This bubble isn't the whole
universe. It's just the part we can
actually see. No matter how powerful our
telescopes become, we will never be able
to look beyond this boundary. You may
ask why so? Well, it's because the
universe is expanding. Space itself is
stretching. Almost all galaxies are
moving away from us. And not just that.
The farther away a galaxy is, the faster
it seems to be moving away. And as the
space farther away from us expands
faster, the objects there move away from
us at speeds greater than the speed of
light due to this accelerated expansion.
The most distant regions of space are
receding even faster relative to us.
It's not that galaxies themselves are
breaking the laws of physics. Instead,
it's space that's expanding so quickly
that light from those regions can never
reach us. So we will never know what
lies beyond that horizon. To address
this problem, scientists assume that the
universe is homogeneous and isotropic,
meaning it appears the same in every
direction and at every location, at
least on very large scales. This
assumption makes it easier to picture
the universe stretching infinitely in
all directions, looking the same even
beyond the limits of what we can
observe. But some recent hints from the
James Webb Space Telescope have raised
questions. The data suggests the
universe might not be perfectly uniform
after all. If that's true, then what
exists beyond our observable universe,
could be very different from what we see
around us. And scientists believe that
everything in our universe, both what we
see and what lies beyond, was once
squeezed into an unimaginably tiny,
dense state, often called the Big Bang
singularity. But don't imagine it as a
dot floating in empty space because
space itself didn't exist yet. The term
singularity is simply a label for a
state we cannot yet fully understand or
describe. No one knows where it came
from or what, if anything, existed
before it. The Big Bang model suggests
that about 13.8 billion years ago, the
universe began from this initial
singularity that expanded extremely
rapidly. But unlike an explosion from a
central point, this expansion happened
everywhere at once. There's no center
and no edge to it. To explain how the
universe expanded so quickly and became
smooth and uniform, scientists proposed
something called inflation, a theory
that suggests the universe expanded
extremely fast in its very first
moments. To account for why the
expansion is still accelerating even
today, scientists introduced the idea of
dark energy, a mysterious force that
seems to push space apart. This idea has
been part of the standard cosmological
model for years. The Big Bang theory has
since become the foundation of modern
cosmology, guiding scientists in
unraveling the history of the universe.
But there are many problems with the Big
Bang model and the discoveries from the
James Webb Space Telescope have been
challenging this model in recent years.
But now things have become even more
puzzling. Recently, Webb found a new
kind of black hole in the early universe
that defies explanation. Some scientists
are beginning to suggest that the big
bang might not be the full story. In a
new study, an international team led by
astrophysicist Ignis Jodbalis from the
University of Cambridge measured the
mass of one of the mysterious little red
dots detected by web. They discovered
that this glowing object named QS01
is actually a black hole with a mass
equal to 50 million suns. But they found
something really odd in this black hole.
The material surrounding this black hole
is very small compared to the black
hole's huge mass. This means that it was
not formed in a normal way such as by
the collapse of stars. Instead, it seems
to be a completely different kind of
black hole. Scientists call these
primordial black holes, which are
thought to have formed in the very first
moments after the Big Bang. If that's
true, it could mean black holes existed
first and galaxies later grew around
them. But the big question remains, how
did these primordial black holes form in
the first place? The standard Big Bang
model doesn't provide a clear answer.
Moreover, the discovery of primordial
black holes could be a gamecher for
cosmology. Scientists believe these
black holes might help answer some of
the biggest questions about the origin
of the universe. Questions that the big
bang model failed to explain. Scientists
say that our universe existed before the
big bang and this could explain how dark
matter came into existence. A recent
study published in the journal of
cosmology and astroparticle physics
proposed that the universe may have had
a secret life prior to the big bang. The
research suggests that before the big
bang, the universe went through a phase
where it first contracted and then
expanded. Imagine it like the universe
shrinking down to an incredibly small,
dense state, almost like compressing a
spring. Then just like a spring bouncing
back, the universe bounced from this
dense state and began expanding again,
leading to the big bang and the universe
we know today. During this phase of
contraction, small differences in the
density of space could have created tiny
black holes. These early black holes,
known as primordial black holes, may
have survived the bounce and continued
to exist as the universe expanded. Some
scientists now think that these ancient
black holes could be what we call dark
matter. This theory tells us that our
universe has a secret past before the
Big Bang. But wait, recently the web
telescope discovered something else that
surprised everyone. Web has also
discovered galaxies at record-breaking
distances. And these galaxies are so
unusual that existing theories are
having a hard time explaining how they
formed. On top of that, many strange and
unknown objects have been spotted in the
early universe, leaving scientists
wondering what they really are. A few
days ago, the James Webb Space Telescope
made its deepest look yet into the early
universe and discovered something no one
expected. In the past, Web has already
spotted some of the most distant
galaxies ever seen. But this time, it
went even further. Scientists found six
galaxies at a red shift of 17 and three
more at a red shift of 25, pushing the
limits of what we thought was possible.
Well, amid the discovery of ancient
galaxies and massive black holes,
astronomers have stumbled upon something
even stranger. A mysterious type of
bright object from the early universe.
You are already familiar with these.
They are nicknamed little red dots. At
first, scientists assumed they were
simply small, compact galaxies, but
follow-up observations shattered that
idea. These are not galaxies at all.
They're something entirely different,
something we've never seen before. A
bold new theory suggests these inigmatic
objects could be black hole stars. And
no, they're not ordinary stars, nor are
they black holes. Instead, they are a
bizarre hybrid, a short-lived cosmic
phenomenon theorized to exist only in
the earliest ages of the universe. A
black hole star forms when an enormous
star collapses under its own gravity.
But instead of immediately becoming a
black hole, the black hole forms at its
core while the rest of the star remains
intact around it. If these little red
dots are truly black hole stars, it
would mean we are looking at an
incredibly rare stage of cosmic
evolution. In addition to this, a few
days ago, the web telescope made a
surprising discovery. It observed the
rotation of galaxies from the very early
universe and found that most of them
were spinning in the same direction.
Scientists still don't have a clear
answer for why this is happening. Some
suggest that these galaxies must have
had an initial rotation right from the
time they were formed. But if that's
true, it points to something even
bigger. The entire universe itself might
have had a rotation from the very
beginning. Interestingly, few years ago,
some scientists have suggested that the
cold spot seen in the cosmic microwave
background might be linked to a possible
rotation of the universe. And now, new
hints from the web telescope also
suggest that the universe could be
spinning. However, scientists point out
that if the universe does have a
rotation, it may not be as simple as a
planet or a star spinning around a
single axis. Instead, the rotation could
be more complex with multiple directions
or a multi-pole structure rather than
just one clear axis. On the other hand,
some scientists believe that our
universe is actually inside a rotating
black hole. Well, all these discoveries,
the evidence of primordial black holes,
massive early galaxies, strange new
objects in the young universe, and even
hints that our universe might be
spinning strongly suggests that the big
bang may not have been the absolute
beginning of everything. It raises the
possibility that the universe has a
hidden past before the big bang or that
another universe existed before ours
with our universe being just one part of
a larger structure. Even Nobel Prize
winner professor Roger Penrose believes
the big bang was not the true beginning.
He has offered a brilliant explanation
of how the universe could exist beyond
the big bang. To explain what he meant,
he gave an interesting example in which
he mentioned a famous painting of angels
and devils created by Dutch artist MC
Cher.
>> So what you can do is you can represent
infinity in this picture. That's a very
nice re representation.
>> You're representing infinity but at a
finite distance.
>> Yes, that's right. So you can make it in
the picture as a finite distance. But as
far as the devils and the angels
themselves are concerned, they keep on
going forever.
And this is a a geometry known as
hyperbolic geometry. It's a very nice
representation of infinity. I'm taking
that picture
as important in thinking about space
time is that the big bang was like one
of those cher boundaries, but it's nice
and smooth. And you can imagine that you
could continue this universe to outside
that region. So even though the Eschher
picture ends with this circular
boundary, you could still imagine that
the spaceime continues out beyond that.
So you could step outside it.
>> He suggests that our universe is just
one in a series of cosmic cycles where
each cycle or aon ends in a kind of
stretched out emptiness and gives birth
to the next. In this view, other
universes existed before ours and more
could follow after. All these
discoveries and new theories are
incredibly exciting, and they might just
be the beginning. Hopefully, in the
future, the James Web Space Telescope
will continue to reveal even more clues
about the true nature of the universe
and how it all began. That's it for this
video. We hope you enjoyed the journey.
