Cosmic Microwave Background Radiation (CMB) and its Anisotropies. …
Dark Matter.
A significant criticism of the Big Bang theory is that it appears to violate the first law of thermodynamics by suggesting the universe originated from “nothing,” essentially creating matter and energy where there was none before, which is considered impossible according to the law stating that energy cannot be created or destroyed; other criticisms include the “horizon problem” and the “flatness problem” related to the uniformity of the universe and its geometry, and the lack of a complete understanding of what caused the Big“
Evidence for anomalous redshift: Redshift observations don’t match predictions from the Big Bang theory.
Large-scale structures: Some structures have been too large to have been formed since the Big Bang.
Light elements: The abundance of helium and lithium doesn’t match predictions.
Cosmic microwave background: The cosmic microwave background radiation doesn’t match predictions.
Inflationary period: The early inflationary period of the Big Bang may violate the rule that nothing can travel faster than light.
Entropy: The development of celestial bodies may defy the rule of entropy, which states that systems grow less ordered over time.
Absence of exotic cosmic bodies: exotic cosmic bodies that the Big Bang should have produced are missing.
One alternative to the Big Bang is the steady state theory, which posits that matter is continuously created throughout the universe. Another alternative is the Big Crunch theory, which describes a closed universe that recollapses back on itself.
The show is criticized for its misogyny, casual racism, and homophobia, particularly towards female characters and characters of color. Sheldon’s representation of neurodivergent people is problematic, as he is often made the butt of jokes and infantilized, perpetuating harmful stereotypes.
key points about criticisms of the Big Bang theory:
Violation of conservation laws:
The most common criticism is that the Big Bang theory contradicts the first law of thermodynamics by implying the creation of matter and energy from nothing.
The horizon problem:
This issue arises from the observation that distant parts of the universe appear to have very similar properties, which would be difficult to explain if they were not causally connected in the early universe.
The flatness problem:
The universe is observed to be remarkably flat, which is considered unlikely if it expanded from a very dense, minor point.
Singularity issue:
The Big Bang theory predicts a singularity, a point of infinite density and temperature, where the laws of physics as we know them break down. This makes it difficult to understand what occurred at the very beginning.
Despite these criticisms, the Big Bang theory remains the most robust framework for understanding the universe’s evolution. It is supported by substantial observational evidence, including the redshift of galaxies and the cosmic microwave background radiation. Ongoing research in cosmology continues to refine our understanding of the universe’s origins and structure.
The Big Bang theory is the prevailing cosmological model explaining the universe’s early development. While it is widely accepted, several scientific criticisms and alternative hypotheses have been proposed. Here are some of the main criticisms:
Singularity and Initial Conditions: The Big Bang theory suggests that the universe began from a singularity, a point of infinite density and temperature. Critics argue that this concept is not well understood and may not be physically meaningful. The laws of physics as we know them break down under such extreme conditions.
Flatness Problem: The universe appears to be very close to geometrically flat. The Big Bang theory does not inherently explain why the universe is so flat. This issue is often addressed by the inflationary model, which proposes a rapid expansion in the early universe, but not all scientists agree on the validity of inflation.
Horizon Problem: The uniformity of cosmic microwave background radiation (CMB) across vast distances poses a challenge for the Big Bang model. Regions of the universe that are far apart have not had enough time to exchange information or energy to reach thermal equilibrium, leading to questions about how they could have the same temperature.
Dark Matter and Dark Energy: The Big Bang model relies on the existence of dark matter and dark energy to explain observations related to the universe’s expansion and structure formation. The nature of these components is still poorly understood, and some critics argue that this reliance indicates gaps in the theory.
Alternative Models: There are alternative theories, such as the steady state theory, which posits that the universe is eternal and unchanging on a large scale. Other models, like cyclic cosmology, suggest that the universe undergoes infinite cycles of expansion and contraction. These alternatives challenge the uniqueness of the Big Bang explanation.
Quantum Gravity: The reconciliation of general relativity and quantum mechanics remains an open problem in physics. Some critics suggest that the Big Bang model may be incomplete without a complete theory of quantum gravity.
Observational Anomalies: Certain observations, such as the distribution of galaxies and the universe’s large-scale structure, sometimes appear inconsistent with predictions made by the Big Bang theory. While these anomalies are often addressed through modifications or extensions of the model, they still raise questions.
Despite these criticisms, the Big Bang theory remains the most robust framework for understanding the universe’s evolution. It is supported by substantial observational evidence, including the redshift of galaxies and the cosmic microwave background radiation.

The JWST did nothing of the sort. And you don’t know what a theory is in science. It doesn’t mean guessing. It doesn’t mean, “I think this happened.” It doesn’t mean many guys got together and decided this was the answer. No. A theory, in science, is an explanation of an aspect of the natural world and universe that can be repeatedly tested and corroborated by the scientific method using accepted protocols of observation, measurement, and evaluation of results.
Besides, the term “Big Bang” was never the name of the theory. Its actual name is the “Lambda-CDM Model.” The term “Big Bang” was created by Fred Hoyle, who mocked it. “So what happened? It was a big bang or something? Hur, hur, hur.”. He favored the steady state model, which stated that the universe had always existed and that matter and energy were continually created through something like a white hole. This, of course, violates the 2nd Law of Thermodynamics, making the universe an open system.
Do you know who first came up with the idea? This man:
G noticed that things were moving away from us, and the farther away they were, the faster they moved away. And that meant that, at some point, everything was closer together. Go back far enough, and it’s all in one space.
The scientific minds at that time dismissed this idea as being, and you’ll love this, too close to creationism. That’s right; a priest is credited with introducing the Big Bang, but scientists dismissed it as not scientific. But like all good scientists, they looked at the evidence, did their research, and admitted he was right.
It wasn’t an explosion but a rapid expansion of spacetime. What caused it? We don’t know, and that’s fine. That means we have something more to learn.
As for the JWST “disproving” the Big Bang? No, it hasn’t. All it’s done is show that part of our understanding is wrong. That doesn’t invalidate it. It just means we need to reevaluate it. Unlike religion, which is dogmatic and static, science changes when new information comes to the fore. Tim Minchin said it best in his beat poem “Storm”:
Science adjusts its views based on what’s observed.
Faith is the denial of observation so that belief can be preserved.
If you show me that
Say homeopathy works, then I will change my mind.
I’ll spin on a fucking dime.
I’ll be embarrassed, but I will run through the streets yelling.
It’s a miracle! Take physics and bin it!
Water has memory!
And whilst its memory of a long-lost drop of onion juice seems infinite
It somehow forgets all the poo it’s had in it!
You show me that it works and how it works.
And when I’ve recovered from the shock
I will take a compass and carve ‘Fancy That’ on the side of my cock.
The JWST did not disprove the Big Bang. You just misunderstood what it did discover.
What are some examples of new information that has changed scientific theories in the past?
