What was the BIG BANG? 6KU (Int 2 / Higher RMPS)

The Big Bang: What was it? When was it? Why do so many of us believe in it?

You need to answer this as if it was an 6 mark question and be confident that you are going to get full marks. Expect to talk about Hydrogen atoms, gravity, cooling and gases. Obviously you need to give more information than this poster.

  1. Big Bang

    -Happened 13.7 billion years ago
    -From a tiny volume of space (singularity) which rapidly expanded
    -Explosion caused waves of energy which are still expanding today
    -Scientists think this started the universe
    -Nothing existed before the Big Bang supposedly
    – Galaxies are still being formed by the expanding universe

  2. The Big Bang was an explosion that happened 13.7 million years ago that created all of space and time, when the explosion happened the universe was extremely hot and very dense, and it expanded rapidly. After the initial explosion the universe cooled alot and energy was converted into particles, then converted into protons neutrons electrons. It kept expanding (even today) and is also cooling (even today).

  3. Big Bang

    The universe is 13.7 billion years old

    All the matter in the universe used to be condensed into a singularity, a point infinitely small and dense

    The universe used to be a cloud of energy/mass despite it being very clumpy today (galaxies being those clumps)

    Space began to expand and pushed matter apart

    The expansion of space is accelerating

    In the beginning the universe was so hot all the universal forces (gravitation, electromagnetism, etc.) were one force

    -The accelerating expansion of the universe will one day spread galaxies so far apart we will not be able to see them because the light leaving them will constantly have new space created in front of it

  4. The Big Bang is a theory that the world began with a big explosion 12-15 billion years ago. The bang created particles, which later on cooled to become atoms. These atoms joined to create elements and other materials. The elements and material joined, creating compounds which eventually became stars, planets, galaxies and eventually the universe. The explosion has caused our universe to move apart and this is proof that the Big Bang happened, an effective argument for the cosmological argument: the Universe has a cause.

  5. The Big Bang Theory
    The Big Bang theory can be used to both support and challenge the existence of God. Scientists say that the Big Bang was a big explosion that caused the universe to start existing and it seemed to have happened form nothing at all. Many theists believe that God caused the Big Bang. The schoolboy objection could still prove that God exists as it could be changed to, if everything has a cause, what caused the Big Bang? It is, however, a viable alternative to the to the universe being created by God. Also, the Big Bang theory is based on science and evidence so it could be said that it is more reliable than religious belief which we cannot prove.

  6. How was the universe created? Many once believed that the universe had no beginning or end and was truly infinite. Through the introduction of the Big Bang theory, however, the universe could no longer be considered infinite. The universe was forced to take on the properties of a finite phenomenon, possessing a history and a beginning. 
    The cosmos inflates, expanding from the size of an atom to the size of a grapefruit in a fraction of a second.
    After inflation the universe is a super-hot mess of electrons, quarks and other particles.
    The Universe is continuously cooling at a rapid pace allowing the quarks to form protons and neutrons.
    3 minutes after the Big Bang protons prevent light from shining so the universe is a super-hot fog.
    After 300,000 years electrons combine with protons to form atoms. Light can finally shine.
    Gravity causes the atoms to form giant gas clouds, some smaller one collapse and form the first stars.
    As galaxies cluster, the first stars die and send heavy elements into space.
    About 15 billion years ago a tiny but powerful explosion started the expansion of the universe, this explosion is known as the Big Bang. At the point of this event all of the matter and energy of space was contained at one point. What existed prior to this event is completely unknown and is a matter of pure speculation. This leaves room for many theories as to the cause of the Big Bang including: God (theists), and a Singularity (naturalists, atheists etc.)


    The big bang is one theory for the development of the universe.

    The big bang theory is that once the universe was very hot and it expanded extremely fast.

    This caused the universe to cool and that is why it’s still expanding.

    The big bang originated from nothing.

    The big bang originated roughly 13.7 billion years ago.

    The big bang explains and describes the general evolution of the universe.

  8. What was The Big Bang?

    According to what people call the big band theory, the universe began growing and expanding from a small volume with extreme temperature and high density. The big bang wasn’t necessary an explosion of matter but it carried matter with it as it expanded. Physicists even think that time began with the big bang. Today just about every scientist believes in the big bang theory. Most people had assumed the universe was fixed in size but new possibilities opened up when Einstein formulated his general relativity theory. The theory allows for expansion of the fabric of space. One of the main observational results that astronomers found out was that the universe was expanding, in other words gaps between galaxies were getting bigger and bigger, this led them to be able to come to the conclusion that everything used to be extremely close together before this so called ‘Big Bang.’

  9. The big bang

    The cosmos goes through a rapid inflation expanding from the size of an atom to the size of a grapefruit in 10¬¬-43 seconds. After the inflation the universe is a soup of electrons, quarks and other particles at 10-32 seconds and at 1027˚C. A rapidly cooling cosmos permits quarks to clump into protons and neutrons. At 3 minutes it is still too hot to form into atoms, charged electrons and protons prevent light from shining: the universe is a super hot fog. Electrons combine with protons to form atoms, mostly hydrogen and helium. Light can finally shine. Gravity makes hydrogen and helium gas join to form giant clouds that will form galaxies. Smaller clumps of gas collapse to form the first stars at 1 billion years. 15 billion years after the initial expansion, galaxies cluster together under gravity. The first stars die and spew heavy elements into space; these will eventually form into new stars and planets. S

  10. The Big Bag theory is the theory that the universe was caused by an explosion, that happened 12-15 billion years ago, which began the universe. According to the theory, the Universe was once in a hot and very dense state that was rapidly expanding After its initial expansion, the universe cooled down, and subatomic particles were made. The gasses Hydrogen and Helium were formed. As time passed, planets were formed. This is how scientists explain the origins of the universe.

  11. According to the Big Bang theory, the Universe was once in an extremely hot and dense state which expanded rapidly. It was a huge explosion that created all the matter that we know today, the matter from the explosion clumped together to form galaxies and planets. The big bang says that the universe came from a singularity and began to expand this rate of expansion is accelerating. This says that the universe originated from one single point and began to expand. It took place 15-20 billion years ago. The universe used to be a cloud of gas.

  12. The universe began with an explosion about 15 billion years ago. There was no obvious cause for the explosion. It generated particles and these slowly turned into atoms and molecules. Gases were then formed from these and over time planets developed. This is the science explanation for the start of the universe through the Big Bang.
