Most scientists today would say there are four main, everyday states of matter (solid, liquid, gas, plasma), plus several more exotic ones that appear only in extreme conditions like ultra‑cold labs or inside stars and particle colliders.

Quick Scoop: So…how many are there?

The twist is that there isn’t a single “official” number; it depends on how strict you are with the definition of a “state.”

  • Textbook view (classic school answer) : 3
    • Solid, liquid, gas.
  • Modern everyday-physics view : 4
    • Solid, liquid, gas, plasma (the ionized gas that makes up stars, lightning, neon signs).
  • Extended physics view (common in popular science) : around 6–7
    • Add plasma, Bose–Einstein condensates, and various ultra‑cold “condensate” phases like fermionic condensates or related exotic forms.
  • Ultra‑nerdy / frontier view : you can list many more exotic phases (quark–gluon plasma, time crystals, topological phases, etc.), so the count can easily go well beyond 10 if you name them individually.

A good, honest short answer for “how many states of matter are there?” in 2026 is:

There are four fundamental everyday states (solid, liquid, gas, plasma), and several exotic states like Bose–Einstein condensates and quark–gluon plasma, so at least 6–7 well‑established ones , plus many more specialized phases proposed and studied in modern physics.

Classic vs modern: why the numbers differ

In school, you’re usually told “three states of matter”: solid, liquid, and gas. That’s still fine for basic life-on-Earth explanations, because that covers ice, water, steam, air, rocks, and so on.

But scientists quickly realized that plasma —gas so hot that electrons are stripped off atoms, turning it into a soup of charged particles—is not just “hot gas,” it behaves differently enough to count as a separate state. Since stars are mostly plasma, many sources now say four fundamental states : solid, liquid, gas, plasma.

Once you go into quantum and high‑energy physics , things explode into many more “phases” of matter, each with unique rules and symmetries.

A quick tour of the main states

Think of the states in layers: everyday, extreme‑hot, and extreme‑cold.

Everyday states (what most people mean)

  • Solid : Particles are packed closely, mostly vibrating in place; matter has a fixed shape and volume (like ice or metal).
  • Liquid : Particles are close but can move around each other; fixed volume but no fixed shape (like water).
  • Gas : Particles are far apart and move freely; no fixed shape or volume, filling any container (like steam or air).

High‑energy states

  • Plasma (4th state) : Gas heated so much that electrons are stripped from atoms, leaving ions and free electrons.
* Found in stars, lightning, fluorescent lamps, and many fusion experiments.
  • Quark–gluon plasma (often called a 5th state) : Matter so hot and dense that protons and neutrons “melt” into their components—quarks and gluons.
* Created for tiny moments in high‑energy colliders like the Large Hadron Collider and thought to have filled the early Universe microseconds after the Big Bang.

Ultra‑cold quantum states

Cool atoms close to absolute zero and bizarre new behaviors show up.

  • Bose–Einstein condensate (BEC) : A cloud of bosonic atoms cooled until they all collapse into the same lowest‑energy quantum state and act like one “super‑atom.”
* First realized in the lab in 1995 with rubidium atoms.
  • Fermionic condensate / related condensates : With fermions (like certain atoms or electrons), you can pair them up so they behave collectively like bosons and condense into a similar ultra‑cold quantum state.

Some authors bundle these last two together as “condensate states,” giving you 7 total : solid, liquid, gas, plasma, quark–gluon plasma, Bose–Einstein condensate, fermionic condensate.

Exotic and “weird” phases: how far can we go?

Beyond those headline states, modern condensed‑matter and high‑energy physics classify a huge variety of exotic or topological phases.

Examples include:

  • Topological states of matter (such as the fractional quantum Hall state) with properties defined by deep mathematical structures rather than simple order like “solid” vs “liquid.”
  • Time crystals , which show a kind of periodic motion in time even in their lowest energy state, breaking time‑translation symmetry.
  • Various superfluids and superconductors , which allow frictionless flow of liquid or resistance‑free electric current under special conditions.

Some popular videos or articles will say “22 states of matter” or throw around big numbers by counting many of these specialized phases separately. That’s not wrong as long as you treat them as different phases , but it’s not a fixed, universally agreed list.

What do forums and recent discussions say?

Modern forum and article discussions often go like this:

“School says 3, but science YouTube says 7, a TikTok claims 22… what’s real?”

The current expert trend in 2020s popular science is to be transparent:

  • Teach 3 or 4 as the basic set for general audiences.
  • Acknowledge at least 6–7 well‑studied states when including quark–gluon plasma and quantum condensates.
  • Emphasize that “state of matter” is a concept from physics, and as we discover more complex phases, the list can grow —so it’s better to think in terms of “many possible phases” rather than a single final number.

So if you’re answering a homework‑style question, “3 or 4 ” is usually what the teacher expects, depending on whether they count plasma. If you’re in a science‑forum or deep‑dive discussion, saying “at least 6–7, plus many exotic phases” is closer to today’s physics.
