2022-08-24: What Makes The Strong Force Strong?

  • 17:31: We don’t see these plasmas actually freeze - just that their spectrum is changed a bit from the typical thermal spectrum of hot matter.

2021-12-29: How to Find ALIEN Dyson Spheres

  • 03:05: ... the Sun produces a thermal spectrum - light generated by its 6000K surface is distributed at all ...
  • 03:24: ... in the process they warm up, shedding all of that energy as a new thermal spectrum, now at 300 or so Kelvin, with its peak at infrared ...
  • 07:20: Each would produce its own thermal spectrum at different temperatures.
  • 08:17: For something with a pure thermal spectrum, we can exactly identify its temperature from, say, the ratio of red light to blue light.

2021-05-25: What If (Tiny) Black Holes Are Everywhere?

  • 09:14: ... on this also, but long story short: if black holes radiate a perfect thermal spectrum then, by definition, that radiation has maximum entropy and contains no ...

2018-04-18: Using Stars to See Gravitational Waves

  • 11:14: Without life, Earth would reflect a higher intensity spectrum closer to the 6,000 Kelvin thermal spectrum it receives from the sun.
  • 11:23: ... a lot of that light and radiates something closer to a 300 Kelvin thermal spectrum. ...

2018-04-04: The Unruh Effect

  • 06:31: Those particles should have the same type of spectrum as Hawking radiation, a thermal spectrum.

2018-03-15: Hawking Radiation

  • 10:17: ... example, in 2001, Parikh and Wilczek got the same thermal spectrum for Hawking radiation by thinking about particles escaping from beneath ...

2015-03-25: Cosmic Microwave Background Explained

  • 01:56: ... emission pattern represented by the graph is called the toaster's thermal spectrum or really an idealization of a thermal spectrum called a black body ...
  • 02:04: Now, everything has a temperature, so everything has a thermal spectrum, and it emits all electromagnetic wavelengths.
  • 02:12: In fact, it's called a thermal spectrum because the light is generated by the random motions of particles in the material.
  • 02:32: The CNB is one of the closest things to a mathematically perfect thermal spectrum that has ever been observed.
  • 02:47: So why does the CNB look like a thermal spectrum at all?
  • 04:37: ... over the course of a few million years, that orangey thermal spectrum of light was redshifted to longer and longer wavelengths, becoming ...
  • 05:10: ... the CNB, or more specifically, the shape of its thermal spectrum, is pretty compelling evidence that when it comes to the color of space, ...
