The Steady State Theory of The Universe
Summary
TLDRThis script explores the steady state theory, which posits the continuous creation of matter in an ever-expanding universe without a beginning or end, proposed by Bondi, Gold, and Hoyle in 1948. However, the Big Bang theory, suggesting a singular explosive origin, is now more widely accepted due to evidence like redshift and cosmic background radiation. Despite this, the Big Bang faces criticism for its implications on the first law of thermodynamics. Scientists use advanced simulations and telescopes to refine our understanding of the universe's origins, with ongoing research aiming to develop more accurate cosmological models.

Q & A
What is the Steady State Theory of the universe?
-The Steady State Theory posits that the universe continuously creates matter as it expands, maintaining a constant average density. It suggests the universe has no beginning or end and remains structurally the same over time.
Who initially proposed the Steady State Theory?
-The Steady State Theory was initially proposed by British cosmologist and mathematician Sir Hermann Bondi, along with Thomas Gold and Sir Fred Hoyle in 1948.
What evidence supports the Steady State Theory?

🌌 Steady State Theory Overview
The Steady State Theory posits that the universe continuously creates matter as it expands, maintaining a constant average density over time. This theory suggests the universe has no beginning or end and was proposed by Hermann Bondi, Thomas Gold, and Fred Hoyle in 1948. It implies a universe where the structure remains unchanged over time, supported by redshift evidence. However, it is not the most accepted theory today.
💥 Introduction to the Big Bang Theory
The Big Bang Theory is currently the most widely accepted model for the origin of the universe. It suggests the universe began as an extremely dense, hot point from which all matter expanded. This theory, proposed in the 1920s and 1930s, was initially met with skepticism but gained support as evidence emerged. The theory is distinct from the Steady State Theory in that it suggests a single creation event of matter rather than continuous creation.
🔍 Evidence for the Big Bang Theory
Key evidence supporting the Big Bang Theory includes the redshift observed in light from distant galaxies, indicating their movement away from us, and the discovery of cosmic background radiation. In 1989, NASA's Cosmic Background Explorer mission provided precise measurements of the oldest light in the universe, further substantiating the Big Bang Theory by showing a uniform temperature variation of 0.005 percent, indicative of the universe's expansion.
🤖 Technological Advancements in Cosmology
The development of high-powered computers and simulations has allowed scientists to model and understand the cosmos more accurately. The US Department of Energy runs the Q Continuum Simulation, one of the largest high-resolution portrayals of the expanding universe, showing the distribution and evolution of dark matter influenced by dark energy. Additionally, telescopes and satellite data, such as from the Hubble Space Telescope, are used to refine our understanding of the Big Bang Theory.
🔬 Ongoing Research and Criticisms of the Big Bang Theory
Despite being the prevailing theory, the Big Bang Theory faces criticism, particularly regarding its violation of the first law of thermodynamics, which states that matter cannot be created or destroyed. This contradiction suggests the universe began from nothing. Ongoing research by cosmologists aims to develop more accurate models of the universe's creation, using technological advancements and observational data to deepen our understanding.

the steady state theory of the universe
is the understanding that the universe
creates matter
constantly as it expands over a period
of time
while still maintaining a constant
average density
[Music]
the theory also suggests that the
continuous creation of matter
ensures that the structure of the
universe remain the same
over time and that the universe itself
has no beginning
nor an end in the cause of time and for
the entirety of its existence
this idea was initially proposed by
british cosmologist
and mathematician sir hermann bondi
along with thomas gold
and sir fred will in the year 1948
they were the people who came up with
the concept that the entirety of the
galaxies
are intermingled this idea
is supported by the redshift evidence
however today the most accepted theory
is not the steady state theory but the
theory
of the big bang
the big bang theory suggests that the
entirety of the universe
started out as a super force that is
dense
very hot and small where stars
atoms form or structure did not cease to
exist
it stated that it was all started by an
enormous explosion
that had created the world in the
universe as we know
today
the difference between the two is that
the steady state theory says
that the universe is expanding and
constantly creating matter
as the universe expands the big bang
however
suggests that the matter was created at
once
and therefore does not expand along with
the universe
the idea of the big bang was proposed in
the 1920s and 1930s
it was rejected by many cosmologists
however
throughout those years there were some
scientists who found evidence to prove
the theory
in 1940 a scientist named george
gamma realized that if the universe is
still expanding today
the wavelength of the light is still
increasing today and concluded
that the universe expanded in cool years
later
after the steady-state theory was
rejected a new evidence was found to
prove
the theory of the big bang the cosmic
background radiation
in 1989 nasa launched a mission called
the cosmic background explorer
the mission precisely measured and
mapped the oldest light
in the universe to the position of 0.005
percent
this as a result helped prove the origin
of the big back theory
as it showed and proved that the
universe expanded
and called however the big bang theory
is still criticized today as it violates
the first law of thermodynamics
which states that mata cannot be created
and nor destroyed
as big back theory suggests that the
universe began
out of nothing to understand one of the
most
puzzling phenomena in science scientists
developed many technological
advancements
including the high-powered computer
simulations
through the application of computer
technology and codes
that stimulate the cosmos scientists
have been able to compare
such simulations with telescopic
observations
the high-powered cosmological computer
simulation
is run by the us department of energy
researchers
and provides one of the largest
high-resolution portrayals
of the expanding universe called the q
continuum simulation
the simulations shows the distribution
and evolution of dark matter
under the influence of dark energy which
helps the scientists build new
understandings
of the big bang theory
additionally scientists also use
telescopes and large amounts of
satellite data such as the hubble space
telescope
to make advancements and build new
understanding upon the big bang theory
although the big bang theory is the most
believed theory of how the universe
began
research is still in place by many
cosmologists
to study the universe to create more
accurate models
of how the universe was actually created
