Hi there! I'm Dr. Smith, a physicist specializing in extreme states of matter. I've spent my career exploring the boundaries of temperature and pressure, from the depths of space to the heart of exploding stars. Your question about the hottest known substance is right up my alley, so let's dive into the fiery world of extreme temperatures!
You might be surprised to learn that pinning down the absolute "hottest" substance is a bit tricky. It's not like measuring the temperature of your morning coffee! The concept of "hottest" depends on what we mean by temperature and how we measure it. But don't worry, I'll guide you through it.
First, let's establish what we mean by temperature. In simple terms, temperature is a measure of the average kinetic energy of particles within a substance. The faster these particles move, the hotter the substance.
Now, when we talk about extremely high temperatures, we often enter the realm of plasma, which is often called the fourth state of matter. Plasma forms when atoms are stripped of some or all of their electrons due to intense heat, resulting in a mix of ions and electrons. Stars, lightning, and the aurora borealis are all examples of plasmas.
Here's where things get really interesting and a bit complex. In typical plasmas, even at incredibly high temperatures, the particles might not be moving that fast individually. Instead, the energy is distributed among a large number of particles. Think of it like a crowded room at a party – the room might be buzzing with energy, but individual conversations might be relatively calm.
However, in some extreme environments, like within powerful particle accelerators or in the immediate aftermath of the Big Bang, individual particles can reach truly mind-boggling energies. In these cases, temperature becomes a less well-defined concept because the energy distribution among particles can be quite uneven.
So, with that in mind, let's explore some of the candidates for the "hottest" substance:
1. Quark-Gluon Plasma: This exotic state of matter is thought to have existed in the first microseconds after the Big Bang. In this plasma, temperatures reach trillions of degrees Celsius, hot enough to melt protons and neutrons into their constituent quarks and gluons. Scientists have recreated quark-gluon plasma in particle accelerators like the Large Hadron Collider (LHC), briefly reaching temperatures of 5.5 trillion degrees Celsius (9.9 trillion degrees Fahrenheit).
2. Supernova Explosions: The explosive death throes of massive stars create some of the most energetic events in the universe. At the heart of these cataclysms, temperatures can soar to billions of degrees Celsius. These extreme conditions forge heavy elements, seeding the universe with the building blocks of planets and life.
3. Particle Accelerator Beams: As I mentioned earlier, particle accelerators like the LHC can accelerate individual particles to nearly the speed of light. While not technically a "substance" in the traditional sense, these beams carry immense energy. For example, the proton beams at the LHC have an energy equivalent to a temperature of quadrillions of degrees Celsius if that energy were to be converted into heat in a macroscopic object. However, it's important to remember that this is not the same as a bulk substance being at that temperature.
So, which one takes the crown for "hottest"? It's difficult to say definitively. If we're talking about the highest temperature ever achieved in a controlled laboratory setting, then the quark-gluon plasma wins with its staggering 5.5 trillion degrees Celsius. However, if we consider the highest temperatures ever reached in the universe, then the extreme conditions within supernova explosions likely take the lead, although precise measurements remain challenging.
The quest to understand and create ever-higher temperatures continues to push the boundaries of science. As we delve deeper into the fundamental nature of matter and the universe's earliest moments, we are sure to encounter even more extreme conditions that challenge our understanding of temperature itself.

The hottest thing that we know of (and have seen) is actually a lot closer than you might think. It's right here on Earth at the Large Hadron Collider (LHC). When they smash gold particles together, for a split second, the temperature reaches 7.2 trillion degrees Fahrenheit. That's hotter than a supernova explosion.
