You are thinking of the Big Bang Theory, where the universe has been expanding for about 14 Billion years. Some scientists think that the universe will continue to expand indefinitely. Others think that the universe will reach a point where the expansion will reverse to a contraction, which would ultimately result into a reversal of the whole Big Bang process. Here is a link that will explain more details:

What else can I help you with?
Which theory suggests that for every big bang there is a crunch?
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.
What is big bounce theorybig bang and big crunch?
The Big Bounce theory posits that the universe undergoes a cyclical process of expansion and contraction, suggesting that the universe expands from a previous collapse, rather than starting from a singular Big Bang. In contrast, the Big Bang theory describes the origin of the universe from an extremely hot and dense state roughly 13.8 billion years ago, leading to its ongoing expansion. The Big Crunch is a hypothetical scenario where the universe's expansion eventually halts and reverses, causing it to collapse back into a singularity, potentially leading to another Big Bang. These concepts explore different aspects of the universe's lifecycle and its ultimate fate.
How old is the big bang theory?
Georges Lemaître proposed the universe's expansion from a single point in 1927. His calculations were supported by Edwin Hubble's observations in 1929. Fred Hoyle (an opponent) coined the term "Big Bang" in 1949. The event itself is estimated to have occurred 13.73 billion years ago.
What states that all matter and energy in the universe exploded ten to twenty billion years ago and began expanding in all directions.?
The theory that describes the origin of the universe as an explosion of all matter and energy is known as the Big Bang Theory. According to this theory, the universe began as a singularity and has been expanding ever since, roughly 13.8 billion years ago. This expansion continues today, leading to the vast and dynamic universe we observe.
What evidence supports the pulsating universe theory?
the pulsating universe theory is when the universe expands (the big bang) then contracts (the big crunch) and so on (it's pulsating). according to this theory right now the universe is expanding, but then it will contract
What are the three main points of the particle theory of expansion and contraction?
The particle theory of expansion and contraction states that matter is composed of tiny particles that are constantly in motion. When a substance is heated, the particles gain energy and move faster, causing them to spread apart and the substance to expand. Conversely, when a substance is cooled, the particles lose energy, move slower, and come closer together, leading to contraction. This behavior is consistent across solids, liquids, and gases, though the extent of expansion and contraction varies by state and material.
What is the theory of the beginning of the universe called the?
The big bang theory which is a theory of cosmology holding that the expansion of the universe began with a gigantic explosion between 12 and 20 billion years ago
The big bang theory states that the galaxies in the universe are?
The big bang theory states that the galaxies in the universe are continuously moving away from each other due to the expansion of space. This expansion suggests that the universe began from a hot, dense state approximately 13.8 billion years ago.
The most recent theory that upholds the big bang theory but suggests a sudden expansion after the bang is called the?
Inflation theory. This theory suggests that in the first moments after the Big Bang, the universe underwent a rapid and exponential expansion, causing it to grow exponentially in size. This concept helps explain certain observations of the universe, such as its large-scale structure and uniformity.
Which theory suggests that for every big bang there is a crunch?
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.
What is a universe that expands and comes back together repeatedly?
A cyclic universe is one that expands and contracts in a never-ending cycle, repeating the process of expansion and contraction indefinitely. This theory suggests that the universe goes through phases of expansion, followed by contraction, ultimately leading to a big crunch, and then starting the cycle again with a new big bang.
Use the particle theory to explain the expansion and contraction of a solid when temperature is changed?
The expansion and contraction using particles is when a liquid melts because the particles get more energy and move around so making the substance appear less then there is and when the particles cool down they loose energy and move around slower so making them appear bigger than when they were warmer.
What is 'Pulsating theory' and 'Steady state theory'?
Pulsating Theory According to this theory, the universe is supposed to be expanding and contracting alternately i.e. pulsating. At present, the universe is expanding. According to pulsating theory, it is possible that at a certain time, the expansion of the universe may be stopped by the gravitational pull and the may contract again. After it has been contracted to a certain size, explosion again occurs and the universe will start expanding. The alternate expansion and contraction of the universe give rise to pulsating universe.
What can a hypothesis become if its supported by repeated experimentation?
Answer this question… What can a hypothesis become if it is supported by repeated experimentation?
What would you say if you believed in oscillating universe theory?
If you believe in the oscillating universe theory, you would argue that the universe goes through a cycle of expansion and contraction, repeating infinitely. This theory posits that the Big Bang was not a one-time event but one of many, with each cycle erasing the previous universe and starting anew.
What is an explanation based on a observations from repeated experiments?
It is a theory.
Which theory is also known as expansion theory?
The expanding universe model
