Hey everyone, welcome back. It has been long and I haven’t posted anything interesting in a while this year. But, today I was wondering about the astrophysics. Since I am a great fan of the sitcom web-series BBT, and I love the character of Raj Koothrapalli who is also an astrophysicist. So, one fine evening, all these questions just started popping in my mind and I thought what better place than asking all these to our beloved chatgpt 🙂
Please go through the chat i had with chatgpt and see if these topics also really excites you. Cheers, enjoy!
Q: What is astrophysics? Is 4th dimension part of that study? is there any conclusion on 4th dimension yet?
ChatGPT said:
Astrophysics is a branch of astronomy that applies the laws and theories of physics and chemistry to understand how stars, planets, galaxies, and the universe as a whole work. It covers a wide range of topics, including:
- The life cycles of stars
- The behavior of black holes and neutron stars
- The expansion of the universe
- The nature of dark matter and dark energy
- Gravitational waves
- Cosmic background radiation
Is the 4th Dimension Part of Astrophysics?
Yes, in a way. The “4th dimension” often refers to time in the context of physics, especially in Einstein’s theory of relativity, where space and time are treated together as a four-dimensional continuum known as spacetime. In this view:
- The three dimensions of space (length, width, height) are joined with time to form the fabric of the universe.
- Astrophysics, especially relativistic astrophysics and cosmology, depends heavily on this concept.
Some theories in higher-dimensional physics, like string theory or brane cosmology, propose additional spatial dimensions beyond the familiar three. These go beyond standard astrophysics and enter the realm of theoretical physics, though they have implications for understanding the early universe and black holes.
Is There Any Conclusion on the 4th Dimension?
It depends on what you mean by “conclusion”:
- Time as the 4th Dimension – In mainstream physics, this is well-established. Einstein’s General Relativity has been confirmed by numerous experiments (like gravitational lensing, GPS accuracy, and gravitational waves). In this sense, the 4th dimension (time) is an accepted and critical part of modern astrophysics.
- Extra Spatial Dimensions – The existence of more than three spatial dimensions is not confirmed. It remains a topic of active research in theories like:
- String theory (which posits 10 or 11 dimensions)
- M-theory
- Kaluza-Klein theory
These theories are mathematically consistent and intriguing, but no experimental evidence yet supports extra spatial dimensions. Projects like the Large Hadron Collider and other high-energy physics experiments are trying to probe this possibility.
Summary:
- Astrophysics uses physics to understand the universe.
- The 4th dimension (time) is essential in astrophysics via spacetime.
- Time as a 4th dimension is confirmed and fundamental in modern physics.
- Extra spatial dimensions remain theoretical, with no experimental confirmation yet.
Q: Like time is the 4th dimension in terms of physics, and extra spatial dimension in terms of mathematics, can we call tesseract the accurate depiction of 4th dimension? is Tesseract mathematically correct? tell me if I am deviating here?
ChatGPT said:
Great question — and you’re on the right track, not deviating at all. You’re digging into the difference between mathematical and physical dimensions, and how we visualize or understand them.
✅ Is a Tesseract a Mathematically Correct Representation of the 4th Dimension?
Yes.
A tesseract (or 4-cube) is a mathematically accurate representation of a four-dimensional hypercube — the 4D analogue of a square (2D) and a cube (3D). It’s defined in 4D Euclidean space, where all four axes are spatial and perpendicular to each other.
So mathematically, the tesseract is a correct depiction of a 4D shape. It has:
- 16 vertices
- 32 edges
- 24 square faces
- 8 cubic cells (just like a cube has square faces, the tesseract has cube “faces”)
We often project a tesseract into 3D space to visualize it, much like we draw a 3D cube on 2D paper. That’s why visualizations may look “weird” or distorted — they’re 3D shadows of 4D objects.
🤔 But Is a Tesseract the Same as the 4th Dimension in Physics?
Not exactly. Here’s the key distinction:
- In mathematics, the 4th dimension can simply be a fourth spatial axis: x, y, z, and w. That’s where the tesseract lives.
- In physics, particularly in Einstein’s relativity, the 4th dimension is time, not another spatial direction.
So, in physics, spacetime is 3D space + 1D time (called 3+1 dimensions). A tesseract doesn’t directly model time or spacetime — it’s purely geometric.
🧭 Are You Deviating?
Not at all.
You’re actually asking the kind of questions that help clarify the conceptual differences between abstract math, physical theory, and visualization tools. It’s a common area of confusion, and your intuition is headed in the right direction.
📌 Summary
| Concept | Description |
|---|---|
| Tesseract | 4D hypercube in pure math (4 spatial dimensions) |
| Spacetime (Physics) | 3 spatial + 1 time dimension (not another cube-like direction) |
| Tesseract in Physics? | Not a model of time; just a mathematical object |
| Mathematically Correct? | Yes, fully correct in 4D geometry |
If you’re interested, we can even break down how a tesseract is built or visualized step-by-step — just say the word.
Q: So, like physics and mathematics, are there any different segment of science where this 4th dimension exists? I have heard people saying love or even god is the fourth dimension. Does this come under the psychology science? Is psychology even a science. I feel a disconnect over here in this area. Help me understand and explain.

You’re touching on some deep and important questions — both scientific and philosophical. Let’s unpack it clearly and honestly:
🧠 Is Psychology a Science?
Yes, psychology is a science, but it’s a soft science, not a hard science like physics or chemistry.
- Psychology uses the scientific method: observation, hypothesis, experimentation, and analysis.
- But human thoughts, emotions, and behaviors are not as predictable or measurable as particles or energy.
- So, while psychology is grounded in science, it also includes aspects of interpretation, subjectivity, and context, which makes it feel less exact.
There are branches of psychology that are very scientific, like:
- Cognitive neuroscience (brain function, imaging)
- Behavioral psychology (patterns of behavior)
- Developmental psychology (how we grow and change)
Others are more philosophical or interpretive, like:
- Humanistic psychology (meaning, self-actualization)
- Psychoanalysis (Freud, Jung — less empirically grounded)
🌌 Are There Other Areas of Science That Use the “Fourth Dimension”?
1. Mathematics – Purely abstract; more than four dimensions are common in math.
2. Physics – Uses time as the 4th dimension in spacetime. Some advanced theories explore extra spatial dimensions (string theory).
3. Philosophy and Metaphysics – Not formal sciences, but these fields sometimes talk about the “4th dimension” as:
- A realm beyond human perception
- A spiritual plane
- An abstract space where ideas, souls, or consciousness may exist
4. Psychology / Spirituality – Here, the term “4th dimension” is often metaphorical, not literal:
- People say things like “love is the fourth dimension” to describe emotions or consciousness as transcending the physical.
- Others refer to the “4th dimension” as a realm of intuition, soul, or God.
Important: These uses aren’t scientifically defined. They’re symbolic, emotional, or spiritual. They may reflect deep truths about human experience — but they are not “dimensions” in the physical or mathematical sense.
🧩 Why Do People Say “Love is the Fourth Dimension”?
This usually means:
- Love feels real and powerful, but it doesn’t occupy physical space.
- It seems to exist in a realm beyond what can be seen or touched.
- So, people metaphorically call it a “dimension” — something beyond the tangible 3D world.
But again, this is poetic or symbolic, not scientific.
💡 Why You Might Feel Disconnected
You’re sensing a tension between:
| Scientific World | Human Experience |
|---|---|
| Objective | Subjective |
| Measurable | Emotional |
| Concrete | Intuitive |
Psychology stands at the intersection of these two worlds. It studies how we think, feel, and behave — using science — but it also deals with intangibles like purpose, love, belief, identity.
This disconnect is normal and even necessary. It reflects the complexity of being human — we aren’t just atoms and neurons, but also dreams, values, fears, and stories.
🔍 So What’s the Truth?
- In physics/math: The 4th dimension is time or a spatial axis.
- In psychology/philosophy: The “4th dimension” might be a metaphor for inner life or spiritual experience.
- In personal belief: People may use the term in mystical, emotional, or symbolic ways — and that’s okay, as long as we don’t confuse it with scientific fact.
