That is the idea that at some very early stage of its development (a fraction of a second after the Big Bang), the Universe expanded extremely fast.

What else can I help you with?
How many concepts are there for the universe?
There are various concepts and theories about the universe, including the Big Bang theory, multiverse theory, inflation theory, and the cosmic microwave background radiation. These concepts seek to explain the origins, expansion, and composition of the universe.
What can the expansion of the universe can be compared to?
The expansion of the universe can be compared to the inflation of a balloon being blown up. Just like how the distances between points on the balloon's surface increase as it inflates, the universe's expansion causes galaxies to move away from each other as space-time itself expands.
Which theory of universe formation was proposed in 1980?
The inflationary hypothesis was developed in the 1980s by physicists Alan Guth and Andrei Linde. Inflation explains the origin of the large-scale structure of the cosmos. Quantum fluctuations in the microscopic inflationary region, magnified to cosmic size, become the seeds for the growth of structure in the universe. Many physicists also believe that inflation explains why the Universe appears to be the same in all directions (isotropic), why the cosmic microwave background radiation is distributed evenly, why the universe is flat, and why no magnetic monopoles have been observed.
What is the correct sequence of events that occurred during the evolution of the Universe?
The correct sequence of events in the evolution of the Universe is: the Big Bang, cosmic inflation, formation of protons and neutrons, formation of light elements, formation of galaxies and stars, formation of planets, and the evolution of life on Earth.
What is cosmic inflation and how does it solve the horizon and flatness problems?
First, let's define terms. The "horizon problem" is the fact that the observable Universe is too uniform. If one does calculations based on simple Big Bang Cosmology -- ie, that the present rate of expansion ("Hubble Expansion") is the rate that has existed since the start of time -- then our Universe did not have enough time to reach the mass density uniformity we see today. It's as if we, while planning to make some iced tea, placed a pan of boiling water a meter away from a pitcher of ice, turned away for one second, and then found the water in both containers was now at room temperature. You'd have every right to ask, "How did they reach equilibrium that quickly?" The "flatness problem" is the fact that the mass density of our Universe is SO CLOSE to the amount that permits stars to form. A Universe more dense than ours would have collapsed in on itself in less than a billion years, and a Universe less dense would have resulted in matter so thin that galaxies would have never formed. In both cases, no heavy elements would have formed in rings around stars, meaning no life could exist. The ratio of the actual mass density and the density that would permit life in our Universe is called Ω. Again, if one does calculations based on simple Big Bang Cosmology, Ω can differ from one by less than 10^-16 (yes, that's a decimal point followed by FIFTEEN ZEROES!), or no life should exist in our Universe. Inflation simply states that, prior to the Hubble Expansion we now see, our Universe was sufficiently dense for a long enough time that it could reach mass equilibrium, which was then followed by a rapid expansion ("Inflation"), which was then followed by Hubble Expansion. If one does the calculations based on an inflationary model, one finds that Ω can differ from one by almost any amount, but will eventually reach near unity when inflation ceases. From then on, Hubble Expansion can continue with Ω being the number we see. Inflation solves other problems as well; but it also makes predictions about what we would see in our present Universe. Specifically, we would see anisotropies in the Cosmic Microwave Background Radiation of a certain size, but no larger. So far, all observations of the CMBR fail to rule out the Inflation Model.
What are the two problems in cosmology that are solved by inflation, and how does inflation help to identify and address these issues?
Inflation in cosmology helps to solve the horizon problem and the flatness problem. The horizon problem is the issue of why the universe appears to be uniform on large scales despite regions being too far apart to have interacted. Inflation rapidly expanded the universe, allowing distant regions to come into contact and reach thermal equilibrium. The flatness problem is the mystery of why the universe is so close to flat, rather than curved. Inflation smoothed out any curvature, making the universe appear flat on large scales.
How is the flatness problem resolved in cosmology?
The flatness problem in cosmology is resolved through the concept of inflation. Inflation is a period of rapid expansion in the early universe that smooths out any curvature, making the universe appear flat. This helps explain why the universe appears flat today despite starting with different curvatures.
How did cosmic inflation resolve the flatness problem?
The cosmic inflation did resolve the flatness problem by the theory which states that the universe appears to have a flat geometry.
What belief is at the core of chaotic inflation theory?
that the early universe underwent a period of unusually rapid expansion
What was a problem with the Big Bang theory?
Several problems that were found with the Big Bang theory were solved by cosmic inflation. I suggest you read about cosmic inflation. One of these problems was the fact that the Universe is fairly homogeneous. Without inflation, it wouldn't have had time to "spread out" any irregularities.
How many concepts are there for the universe?
There are various concepts and theories about the universe, including the Big Bang theory, multiverse theory, inflation theory, and the cosmic microwave background radiation. These concepts seek to explain the origins, expansion, and composition of the universe.
HOW WAS THE UNIVERSE CREATED?
God made it.
How did the size of the universe change?
In the immediate aftermath of the "Big Bang" there was rapid inflation of the universe. That slowed and the universe is now believed to be still, slowly, expanding.
What can the expansion of the universe can be compared to?
The expansion of the universe can be compared to the inflation of a balloon being blown up. Just like how the distances between points on the balloon's surface increase as it inflates, the universe's expansion causes galaxies to move away from each other as space-time itself expands.
The universe how big is it?
This is an area of active research... meaning, nobody really knows. The visible Universe has a radius of about 46 billion light-years. According to the "inflation" theory (basically, the modern version of the Big Bang theory), the total size of the Universe MIGHT be millions or billions of times bigger.

Were there any modifications to the big bang theory?
Yes, the Big Bang theory has gradually evolved. I will not talk here about wild speculations that are not generally accepted by the scientific community. However, one important additional to the theory, that is now generally accepted, is the cosmic inflation. There are strong reasons to believe that - for reasons not yet entirely understood - during a very short time, the Universe increased tremendously in size - "exponentially", they say. Eventually this stopped - the Universe is still expanding, but not at such a fast rate.While it is not known what caused this inflation (a hypothetical particle called "inflaton", it is said), the inflation does explain some things about the Universe that are otherwise quite problematic.
