It violates the first law of thermodynamics, which says you can’t create or destroy matter or energy. Critics claim that the big bang theory suggests the universe began out of nothing. Proponents of the big bang theory say that such criticism is unwarranted for two reasons.
The first is that the big bang doesn’t address the creation of the universe, but rather the evolution of it. The other reason is that since the laws of science break down as you approach the creation of the universe, there’s no reason to believe the first law of thermodynamics would apply.
Some critics say that the formation of stars and galaxies violates the law of entropy, which suggests systems of change become less organized over time. But if you view the early universe as completely homogeneous and isotropic, then the current universe shows signs of obeying the law of entropy.
Some astrophysicists and cosmologists argue that scientists have misinterpreted evidence like the redshift of celestial bodies and the cosmic microwave background radiation. Some cite the absence of exotic cosmic bodies that should have been the product of the big bang according to the theory.
The early inflationary period of the big bang appears to violate the rule that nothing can travel faster than the speed of light. Proponents have a few different responses to this criticism. One is that at the start of the big bang, the theory of relativity didn’t apply. As a result, there was no issue with traveling faster than the speed of light. Another related response is that space itself can expand faster than the speed of light, as space falls outside the domain of the theory of gravity.
There are several alternative models that attempt to explain the development of the universe, though none of them have as wide an acceptance as the big bang theory:
The steady-state model of the universe suggests the universe always had and will always have the same density. The theory reconciles the apparent evidence that the universe is expanding by suggesting that the universe generates matter at a rate proportionate to the universe’s rate of expansion.
The Ekpyrotic model suggests our universe is the result of a collision of two three-dimensional worlds on a hidden fourth dimension. It doesn’t conflict with the big bang theory completely, as after a certain amount of time it aligns with the events described in the big bang theory.
The big bounce theory suggests our universe is one of a series of universes that first expand, then contract again. The cycle repeats after several billion years.
Plasma cosmology attempts to describe the universe in terms of the electrodynamic properties of the universe. Plasma is an ionized gas, which means it’s a gas with free roaming electrons that can conduct electricity.
There are several other models as well. Could one of these theories (or other ones we haven’t even thought of) one day replace the big bang theory as the accepted model of the universe? It’s quite possible. As time passes and our capability to study the universe increases, we’ll be able to make more accurate models of how the universe developed.

The inflationary epoch lasted from 10−36 seconds after the conjectured Big Bang singularity to sometime between 10−33 and 10−32 seconds after the singularity.
Following the inflationary period, the universe continues to expand, but at a less rapid rate.[1]
Inflation theory was first developed in 1979 by theoretical physicist Alan Guth at Cornell University.
It was developed further in the early 1980s. It 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 (see galaxy formation and evolution and structure formation).[2]
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.
The detailed particle physics mechanism responsible for inflation is unknown.
The basic inflationary paradigm is accepted by most physicists, as a number of inflation model predictions have been confirmed by observation;[3] however, a substantial minority of scientists dissent from this position.[4][5][6]
The hypothetical field thought to be responsible for inflation is called the inflation.[7]
In 2002, three of the original architects of the theory were recognized for their major contributions; physicists Alan Guth of M.I.T., Andrei Linde of Stanford, and Paul Steinhardt of Princeton shared the prestigious Dirac Prize "for development of the concept of inflation in cosmology".[8]
In 2012, Alan Guth and Andrei Linde were awarded the Breakthrough Prize in Fundamental Physics for their invention and development of inflationary cosmology.[9]
The model describes how the universe expanded from a very high-density and high-temperature state,[5][6] and offers a comprehensive explanation for a broad range of phenomena, including the abundance of light elements, the cosmic microwave background (CMB), large scale structure and Hubble's law.[7]
If the known laws of physics are extrapolated to the highest density regime, the result is a singularity which is typically associated with the Big Bang.
Physicists are undecided whether this means the universe began from a singularity, or that current knowledge is insufficient to describe the universe at that time.
Detailed measurements of the expansion rate of the universe place the Big Bang at around 13.8 billion years ago, which is thus considered the age of the universe.[8]
After the initial expansion, the universe cooled sufficiently to allow the formation of subatomic particles, and later simple atoms.
Giant clouds of these primordial elements later coalesced through gravity in halos of dark matter, eventually forming the stars and galaxies visible today.
Since Georges Lemaitre first noted in 1927 that an expanding universe could be traced back in time to an originating single point, scientists have built on his idea of cosmic expansion.
The scientific community was once divided between supporters of two different theories, the Big Bang and the Steady State theory, but a wide range of empirical evidence has strongly favored the Big Bang which is now universally accepted.[9]
In 1929, from analysis of galactic redshifts, Edwin Hubble concluded that galaxies are drifting apart; this is important observational evidence consistent with the hypothesis of an expanding universe.
In 1964, the cosmic microwave background radiation was discovered, which was crucial evidence in favor of the Big Bang model,[10] since that theory predicted the existence of background radiation throughout the universe before it was discovered.
More recently, measurements of the redshifts of supernovae indicate that the expansion of the universe is accelerating, an observation attributed to dark energy's existence.[11]
The known physical laws of nature can be used to calculate the characteristics of the universe in detail back in time to an initial state of extreme density and temperature.[12]"
Scientists have finally discovered why the Universe
is expanding...It’s trying to get away from Chuck Norris.
What is it expanding in to?................
now...tell me another one!

It seems to me that the universe is expanding at the rate of the next waist size in pants every year.
Can you imagine how much cloth you would need to make a pair of pants for the universe?
“Galaxies are a lot like blueberries”
Galaxies need sugar and whipped cream?
“Galaxies are like blueberries”
No they’re not.
They’re like cocktail weenies.
This is old news.
If the universe is indeed expanding, then why aren’t my pants?
(Seen in a cartoon way back when)
According to most 'experts', nothing. The Universe is everything. Others think there may be multiple universes.
Yeah, about 13.7 billion years old.
” the laws of science break down”
NO. The laws of science are inadequate to explain what happens as you approach the creation of the Universe.
Revise the laws of science. Oh, you can’t?
My previous post was a joke :)
Here’s a guy who doesn’t mix the blueberry sauce into the muffin mix telling us about the universe.
Isn’t there some kind of law against explaining the universe until you’ve made a decent batch of blueberry muffins?
If not, there should be.
They can't come close to fully explaining what's going on in the present, neither on the grand scale, or quantum realm. Many major mysterious remain.
Mmmmmmm......
I like my Galaxies with some coffee.
