How Did The Universe Begin?

13.8 billion years ago the universe

began in one moment there was nothing

and the

next everything just how this is

possible is perhaps the biggest question

in all of science crossing the

boundaries between Theory and experiment

physics and philosophy everything we

know about our universe hinges on

mechanism process and causality we

strive to understand understand the

reasons things are the way they are and

yet at the most fundamental level we do

not know how or why the entire universe

came to

be but this lack of explanation is not

for want of

searching perhaps as famed cosmologist

Steven Hawking once supposed there

really was nothing before considering

space and time as inherent conjoined

properties of the universe we inhabit

the beginning of that Universe marked

the beginning of time before time there

could be no space and therefore no

Universe considering the geometry of

SpaceTime back through the ages he saw

it contract curve around and eventually

round off searching for something beyond

that would be as meaningless as

searching for something that was north

of the North Pole or perhaps there was

no actual beginning but rather a limit

to our powers of observation scientists

believe that it was a split second

period of exponential expansion known as

inflation that put the bang in the Big

Bang and which set the stage for

everything that was to follow our

inflation stopped after a tiny fraction

of a second but some physicists have

argued that this is not the only period

of inflation in the cosmos as a whole

rather inflation would continue

elsewhere eternally producing bubble

universes distributed through a potent

Everlasting Multiverse or perhaps our

current universe is merely the latest in

a long and potentially infinite series

of expanding and Contracting Cosmos a

theory known as the big bounce in this

instead of starting from nothing and

inflating exponentially to reduce the

structure we see today contemporary

physicists like Paul steinhardt suggest

a cyclical growth and contraction of

everything within the universe or

perhaps our understanding of scale is

fundamentally incomplete physicist Roger

Penrose considered the properties of

shapes regardless of their size and

believes we can do the same with the

cosmos in this idea the universe loses a

sense of time and scale at the

infinitely small and the infinitely big

and becomes to all intents and purposes

equivalent the game of chess played the

same whether on a board that fits in

your pocket or spans an entire Courtyard

or perhaps our Cosmos came about as a

transient Collision of dimension

String Theory attempts to explain the

fundamentals of reality as Tiny

vibrating strings within an

11-dimensional reality of hyperspace the

three dimensions of space and one

dimension of time that we experience

within our Cosmos are merely a single

brain in the overall bulk with the

beginning and growth of our universe

coming about as higher order brains

Collide or perhaps there is something

else some corner of mathematics or

physics that we have yet to shine a

light into and which for the time being

eludes our

understanding for now our universe's

origin story remains a mystery a

years ago the universe did begin and

this is the story of what happen

next thank you to better help for

sponsoring this video this is Proxima

centuri even if we traveled at more than

50,000 km an hour it would still take us

more than 80,000 years to arrive there

and it is our closest star it's

estimated there are 100,000 million more

distant stars in the Milky Way and so

sometimes it can be overwhelming to

square our own lives with the vastness

of everything else and to work these

things through it's nice to have some

help better help is the world's largest

therapy service and it's 100% online

with better help you can tap into a

network of over 30,000 licensed and

hotu and I've also linked them Below in

the description thanks to betterhelp for

supporting educational content on

YouTube where is the hottest place in

the

universe you might expect to find it in

the natural Fusion reactor at the center

of a star but even as you incinerate in

the the plunge through its fiery depths

your journey would be in vain

temperatures at the core reach a mere 15

million de Celsius you may look to even

more violent phenomena in the cosmos

like explosive supern noi here during

the dramatic death of a star superheated

shells of gas are rejected many light

years in every direction leaving a

gravitationally compactified neutron

star at their Center temperatures here

far exceed normal Stellar furnaces

reaching 100 billion de C but this still

isn't the hottest temperature to be

found in fact the highest temperature

that has ever been recorded anywhere in

our vast Cosmos was 100 m beneath the

snow covered ground near the shores of

Lake Lal in

Switzerland and it didn't come about

from a natural process but rather the

concerted efforts of hundreds of

scientists and billions of euros worth

of research and development in cern's

Large Hadron Collider where individual

particles are routinely smashed into one

another at velocities approaching the

speed of light the Collision of two lead

atoms in 2012 briefly produced a

temperature of around

5.5 trillion de C 50 times hotter than a

supernova but this still isn't even

close to the highest possible

temperature temperature is little more

than a manifestation of a particle's

energy its motion or how fast it's

vibrating absolute zero marking 0 Kelvin

is the lowermost limit where particles

hypothetically would come to a complete

shuddering stop were it possible to

reach but there is also an upper limit

too an absolute hot that marks the

highest temperature before the particles

themselves are torn apart by their own

energy it it's known as the plank

temperature and it is around 1.4 * 10 to

the 32 kelv Max plank who gave his name

to this impossibly blistering

temperature was a German theoretical

physicist who found his academic stride

around the beginning of the 20th century

his ideas are seen as the founding

blocks of quantum physics and led to the

quantization of light into discrete

chunks of energy called photons but they

also led him to consider the fundamental

Quant of other natural

phoma using such Universal qualities as

the speed of light and the force of

gravity in combination with his aonomus

plank constant he defined the plank

length the smallest Quantum of distance

as around 1.6 * 10- 35 M about 100

quintilian times smaller than a proton

the time it takes for light to travel
