What is a simple explanation for the Big Bang Theory?

User Avatar

Asked by Wiki User

The Big Bang Theory is the scientific explanation for how the universe began about 13.8 billion years ago. It suggests that the universe was initially in a hot, dense state and has been expanding ever since. This theory is supported by evidence such as the cosmic microwave background radiation and the observed redshift of distant galaxies.

Was the word created by a big bang?

User Avatar

Asked by Wiki User

Yes and no. According to current theory ALL matter has its origins in the big bang some 13.7 billion years ago. The solar system we live in (Earth included) is thought to have accreted from a nebula bout about 4.5 billion years ago.

The matter which makes up our solar system was then created in the big bang, but the solar system itself (our sun and earth included) wasn't formed from that matter until 9 billion years later.

Were stars and galaxies created during the big bang?

User Avatar

Asked by Wiki User

Yes, stars and galaxies were not created during the Big Bang itself. The Big Bang theory describes the rapid expansion of the universe from a hot, dense state about 13.8 billion years ago. Stars and galaxies formed later as the universe cooled and matter began to clump together due to gravity.

Why is the big bang theory not an accurate name for what happened?

User Avatar

Asked by Wiki User

The term "Big Bang" can be misleading as it gives the impression of an explosion. In reality, it was a rapid expansion of space-time that started the universe and not an explosion from a single point. The theory also doesn't address what happened before the initial expansion.

What century did the big bang take place?

User Avatar

Asked by Wiki User

The Big Bang is estimated to have occurred around 13.8 billion years ago, at the beginning of the universe's expansion. It is not directly associated with any specific century, as it took place long before the concept of centuries existed.

Does spin have anything to do with gravitational attraction?

User Avatar

Asked by Wiki User

Spin does not have a direct impact on gravitational attraction. Gravitational attraction is primarily determined by mass and distance, as described by Newton's law of universal gravitation. Spin is a property of a particle related to its angular momentum and does not affect its gravitational interaction.

Why a new theory is often greeted with scepticism and takes time to become accepted?

User Avatar

Asked by Wiki User

New theories often challenge established beliefs and require substantial evidence to support their validity. Therefore, they are initially met with skepticism as scientists and experts scrutinize their methods and results. It takes time for a new theory to become accepted as more studies confirm its findings and it is replicated by other researchers.

How did Fred hoyle regard the big bang theory?

User Avatar

Asked by Wiki User

Fred Hoyle was a proponent of the steady-state theory of the universe and was critical of the Big Bang theory. He famously likened the Big Bang theory to a "Big Bang" creation event and continued to advocate for his steady-state theory even after evidence supporting the Big Bang theory emerged.

Did the big bang theory create the volcanoes?

User Avatar

Asked by Wiki User

No, the Big Bang theory explains the origin of the universe and does not directly relate to the creation of volcanoes. Volcanoes are formed by the movement of tectonic plates on Earth's surface, which cause magma to rise and erupt through the Earth's crust.

How long does a flash bang last?

User Avatar

Asked by Wiki User

A flash bang typically lasts for about 1-2 seconds, during which it emits a bright flash of light and a loud bang to disorient individuals nearby. The effects can vary depending on the type and strength of the device used.

Who is first credited for the Big Bang Theory?

User Avatar

Asked by Wiki User

Georges Lemaître, a Belgian physicist and Roman Catholic priest, who, in 1927, independently used Friedmann's equations to propose that the inferred recession of the spiral nebulae (per Edwin Hubble's discovery of 1924) was due to the expansion of the Universe, is called the pioneer or father of the Big Bang Theory. As such, the Jesuit priest Georges LeMaitre was credited with being the first to mathematically detail a cosmological study now known as the Big Bang.

However the consensus for modeling cosmology was agreed upon based on the work of four scientists: Alexander Friedmann, Georges Lemaître, Howard Percy Robertson, and Arthur Geoffrey Walker. Occasionally referred to as the FLRW, FRW, FL, or RW (e.g., a complete or partial combination of their last initials) Universe, it presents a metric used to explain Einstein's field equation of general relativity and thus became the foundation for the currently understood version of the standard 'Big Bang Theory'.

Note: While the Friedmann Theory preceded the Big Bang Theory, the developed equations were fundamental to establishing a foundation for the Big Bang Theory. Alexander Alexandrovich Friedmann is best known for his pioneering theory that the universe was expanding, governed by a set of equations he developed from Albert Einstein's equations of general relativity, showing that the Universe might be expanding in contrast to the static Universe model advocated by Einstein at that time. From these equations he postulated three Friedmann models describing positive, zero and negative curvature respectively. This dynamic cosmological model of general relativity would come to form the standard for both the Big Bang and Steady State theories.

The name "Big Bang" was coined by Sir Fred Hoyle, who was a life-long proponent of the alternative "steady-state" theory of the universe. He used the phrase "big bang" in a sarcastic way.

Why is the big bang theory compared to a firework?

User Avatar

Asked by Wiki User

The comparison between the Big Bang theory and a firework is made because both involve a sudden and rapid expansion of energy and matter from a single point of origin. In a firework, the explosion releases colorful sparks and light in all directions, similar to how the universe expanded from a hot, dense state in the Big Bang theory. Both events result in a dynamic and visually captivating display.

What does background theory mean?

User Avatar

Asked by Wiki User

Background theory refers to the existing body of knowledge, principles, or hypotheses that provide context and support for the topic or research at hand. It helps establish a foundation for understanding the subject matter and may include established concepts, historical context, and relevant research findings.

What would've happened if the big bang never took place?

User Avatar

Asked by Wiki User

If the Big Bang never took place, the universe as we know it would not exist. The universe began as a singularity and expanded rapidly from that point. Without this event, there would be no galaxies, stars, planets, or life as we know it.

Has the big bang theory become an argument of semantics?

User Avatar

Asked by IAM

The Big Bang theory can be debated by some based on semantics, as understanding and interpreting the terminology and concepts involved can vary between individuals. However, the overall theory itself, which describes the expansion of the universe from a singularity, is supported by extensive observational evidence.

Which theory suggests that for every big bang there is a crunch?

User Avatar

Asked by Wiki User

The theory that suggests for every big bang there is a crunch is known as the "Big Crunch" theory. It proposes that the expansion of the universe will eventually stop and reverse, leading to a contraction of the universe back to a singular point, followed by another big bang.

Why does string theory imply that 11 dimensions exist?

User Avatar

Asked by Wiki User

If one does the mathematics (which are *WAY* beyond the math level of even most scientists), one finds that string theory works only if one assumes the vibrations are aking place in eleven dimensions. Choose another assumption and the mathematics falls apart. Or, more exactly, the mathe eventually leads to falsehoods.

It is SOMETHING like this: if one assumes that there are ten dimensions in string theory, you end up with 1 = 0

Only if you assume that there are eleven dimensions does one get 1 = 1

What is the friction in a quasar created by?

User Avatar

Asked by Wiki User

The friction in a quasar is created by the immense gravitational forces acting on the material falling into the supermassive black hole at the center of the quasar. As material spirals inward, it heats up and generates intense radiation and energy, leading to the bright and energetic nature of quasars.

Is Fred Hoyle irony behind how the big bang theory was named?

User Avatar

Asked by Wiki User

Yes, Fred Hoyle's use of the term "big bang" to describe the theory of the universe's origin was meant to be dismissive and to mock the idea. He believed in a steady-state theory instead. Despite his intentions, the term stuck and is now commonly used to describe the moment of the universe's creation.

Who is scientist that made the big bang theory?

Asked by Wiki User

The big bang theory was developed by Belgian priest and physicist Georges Lemaître in the 1920s. He proposed that the universe began as a primeval atom, which expanded to form the galaxies we see today.

What is the irony how this was named the big-bang theory?

User Avatar

Asked by Wiki User

The term "big bang" was actually coined by astronomer Fred Hoyle as a way to criticize the theory, since he believed the universe had no true beginning. However, the term stuck and is now used to describe the prevailing scientific explanation for the origin of the universe. So, the irony lies in the fact that a term originally intended as a criticism is now widely accepted and used to describe the theory itself.

What was the irony behind how this theory was named the big-band theory?

User Avatar

Asked by Wiki User

The term "big bang" was actually coined by physicist Fred Hoyle, who did not believe in the theory. He used the term sarcastically during a radio broadcast in 1949. However, the name stuck and is now commonly used to describe the accepted scientific explanation for the origin of the universe.
