thirdly jwst remarkable infrared

capabilities allow us to examine the

universe's Origins it revealed an

abundance of galaxies that formed a few

hundred million years after the big bang

it provided the opportunity to examine

galaxies in their formative phases it

contradicted our previous hypothesis

regarding the sequence of early Galaxy

formation the observable universe and

its boundaries have you ever thought of

the vastness of our universe consider

the universe to be a vast theater here

dazzling stars shine galaxies revolve

and Mysteries hide this vast expanse is

known as the observable universe it's a

realm that surpasses human comprehension

while adhering to the laws of nature the

observable universe is comparable to a

cosmic window through it we can observe

the cosmos as a whole this is possible

because instruments like telescopes

enable us to analyze the universe the

cosmic speed limit is known as the speed

of light it travels at an astounding

299,792,458

m/s so our perspective is restricted to

information conveyed by light over the

years to comprehend its operation

Envision the universe is a large dark

chamber here your telescope acts as a

flashlight the flashlights beam will

only reveal a small portion of the area

it illuminates through the telescope

this portion of the universe can be

observed the darkness is widespread we

cannot see what lies beyond the

boundaries of our perception according

to researchers the observable universe

spans approximately 93 billion light

years it is comparable to gazing into a

vast extent of reality it's a place

where Gala

stars and Celestial marbles unfold

however if the universe is only 13.8

billion years old how could something be

extended to 93 billion like years it is

a Divine mystery the expansion of the

universe resembles raisin bread baking

in an oven in this analogy consider

galaxies as raisins as the dough expands

the raisins become further and further

apart since the Big Bang this process

has remained constant galaxies continue

to drift further and further apart as a

result some galaxies are so distant that

the light they radiate hasn't even had a

chance to reach us it is comparable to

pursuing a train that had already left

this limit known as the particle Horizon

indicates the end of the universe that

can be observed and what do you know

instead of winding down the expanse of

the universe is accelerating dark energy

is a mysterious force that propels

galaxies apart it works to increase

their momentum in other words words some

galaxies will ultimately be driven

further apart they might move beyond the

observable universe's Edge what is

beyond this boundary the reality is that

we are clueless it is unknown territory

a realm concealed from our view it is

comparable to staring into the murky

distance without seeing what lies Beyond

according to many researchers Galaxy

clusters have yet to be discovered

unveiling ancient galaxies using data

gathered by jwst scientists have made a

new discovery it says that these

galaxies formed within 500 to 700

million years of the Big Bang it signals

the beginning of the universe for this

to make sense we need to consider that

the universe is

approximately 13.8 billion years old the

light emitted by these galaxies has been

traveling through space for billions of

years it is a conduit of information

from the past they were among the first

to illuminate the void following the Big

Bang it explains their importance this

period known as the Dark Ages is a key

period in Cosmic history by observing

these galaxies researchers hope to

comprehend the Dark Ages better these

galaxies are the universe's grandparents

they provide details on how the universe

began their light reveals much about the

early processes that formed modern

galaxies stars and systems comparison to

other cosmological observations the

findings of jwst reveal astounding

contrasts and comp comparisons with

other cosmological

observations the universe is a puzzle

with distinct components and each of

these observations serves as a clue we

can connect these Clues to understand

the cosmos better the Hubble Space
