This telescope does detect 750 unexplained galaxies outside our observable universe. It challenges the big bang theory.
The history of our universe is a very interesting tale that has attracted the attention of human beings for years. Beginning from ancient times, humans began to ask questions regarding how and why the cosmos surrounding them came into being. Across ages, scientists have developed different theories and models explaining how the universe came to be, and one of the most known theories is called the Big Bang theory.
However, over the years, with numerous discoveries and
observations, this theory appears to have faced criticism and opened a
floodgate of new concepts surrounding how the universe came to be. In the
following article, we will explore how the James Webb Space Telescope has
changed our view of the universe by discovering 750 galaxies that defy our
previous views of the universe .
The Big Bang theory is one of the first explanations
handed down to humanity regarding the origin of the universe. According to the
theory, all matter in the universe came from some sort of unknown source and
expanded rapidly. It therefore is this explosion of matter that led to the
universe in its current form.
The theory of the Big Bang has been broadly accepted
as the explanation of how the universe began. According to the Big Bang theory,
the universe of today emanated from some cataclysmic phenomenon known as the
Big Bang around 13.7 billion years ago. At that time, everything was contained
in a singularity - a very tiny point of matter and energy and fundamental laws
of the universe. Density and temperature at singularity were so extremely high
that the principle of laws as we know them did not apply.
Expansion of the universe and Dark energy
Since the Big Bang, the universe has been in
expansion. The cause of this expansion is dark energy, a denser energy than the
galactic energy common to view. Dark energy, serving as an antigravity, does
not permit the gravitational force between galaxies to attract them; hence,
expands in all directions. Expanding will take galaxies further apart, so it
might be said that the universe is expanding.
So scientists for decades have been collecting evidence and data to support the Big Bang theory of the universe's expansion. Data for all these years seemed to show that we indeed live in an expanding universe, with galaxies growing away from us as time progresses.
The Criticism of the Big Bang
The recent observation of the universe has raised very important questions regarding whether the Big Bang theory is valid or not. The source of this exciting development is the powerful tool that is James Webb Space Telescope, which offers us the opportunity to explore in detail and clarity the cosmos as has not yet been done before.
The James Webb Telescope has observed 750 new galaxies
that have no resemblance to what was thought. These observations directly
discounted the Big Bang hypothesis, which existed for a long time as
unquestionable fact in cosmology. The captured galaxies from the telescope do
not match the earlier predictions based on the Big Bang theory. They appear to
be much smaller, smoother, and older galaxies than imagined.
The mystery of the observed galaxies
The images captured by the James Webb Telescope are surreal. Hundreds of galaxies are visible in one image, all tied together dancing in cosmic harmony. It was puzzling the scientists as these were not like what was expected. They did not seem chaotic and disjointed because of the multiplicity of mergers and collisions but instead smaller and smoother than anyone could have thought them to be, besides showing a remarkable age with interesting speculations on their evolutionary paths.
These were surprises that raised eyebrows among
scientists and brought about a rethink on previously accepted theories about
galaxy formation and evolution. The observation of galaxies that are two to
three times smaller than expected challenges the expected behavior in an
expanding universe, where objects are supposed to appear larger as distance
increases.
The softness and antiquity of galaxies
Another interesting feature is the smoothness of these galaxies. In fact, The big Bang theory dictates that since the formations and evolutions of galaxies are dynamic in nature, it will be possible to notice irregularities and variation within their structures. However, the images reveal unusually smooth galaxies without at least one degree of complexity and roughness that would normally be expected to be seen in galaxies of their age.
This observation seems to contradict the traditional
time-order of galaxy building within the Big Bang cosmology. According to the
Big Bang theory, at the beginning of the universe, all matter, energy and
building blocks in the universe must have been compressed into an infinitely
dense singularity. However, the observed galaxies appear too old to be
accommodated by this theory and must have existed before the singularity.
Cosmic inflation and its implications
To understand these surprising observations in detail, one should remember something about cosmic inflation. Cosmic inflation refers to the time when the universe started increasing exponentially with an extremely rapid and violent expansion that is much greater than the speed of light. In this process, the stretching of space plus the carried matter and energy were expanded.
Cosmic inflation played the most important role as it smoothed out irregularities in the large scale of structure and distributed matter and energy homogeneously. However, new observations suggested that galaxy mergers are not a usual process in galactic evolution, and newly discovered galaxies seem to have experienced few or no mergers. This subsequently raises questions on how these small galaxies would have grown into the massive galaxies we view in space today.
Implications of New Discoveries
The observations made by the James Webb Telescope have
given deep questions that raise our understanding of previous conceptions of
the universe and its formation time. The galaxies that have been detected
compete with evidence against the Big Bang theory, which sets every scientist
back as they seek to make new conclusions in the comprehension of the origin of
the cosmos.
This new knowledge reminds us that even the previously accepted theories could be questioned depending on new observations and discoveries. Once we continue exploring and studying more about the universe, further possibilities open to understand our cosmic origin to a greater extent.
Conclusion:
Here, the James Webb Space Telescope has discovered
750 galaxies that create fragmentation upon our earlier conceptions. Such
discovery ranges from the concept of Big Bang theory to its evolution in how
the universe should have been evolving, thus raising a question over some of
the prevalent formulas. These galaxies can be seen better as smoother, smaller,
and older than they were expected, thus bringing about a change in the existing
theories on galaxy formation and evolution.
As science grows, so does what a person will learn and has to change about how they thought something was. Take this recent discovery, for instance. It goes to show that the universe is an ever-changing place and that the universe still has much in store for further discoveries and understanding of the cosmos surrounding us.
