New analysis shows atoms slow down more within colder blackbody radiation

New analysis shows that atoms will encounter high frictional forces in the presence of blackbody radiation at lower temperatures. Accounting for this effect could help researchers to improve the accuracy of high-precision experiments.

Blackbody radiation (BBR) contains electromagnetic waves with characteristic spectra, which changes shape depending on the temperature of the body. When moving atoms encounter these fields, they experience a repulsive force which slows down their movement towards the source of the radiation.

Through new analysis published in The European Physical Journal D, Vipul Badhan and colleagues at Guru Nanak Dev University, India, show that the influence of this "blackbody friction force" (BBFF) is particularly strong at lower temperatures.

The influence of BBFF could become particularly strong in high-precision experiments involving atoms and nuclei: from atomic clocks and interferometers to quantum sensors and gravitometers. It is also expected to affect the behaviors of atoms in the remnants of supernovae, and could even impact the cutting-edge techniques used to probe some of the most fundamental aspects of the universe: including dark matter and gravitational waves. An improved understanding of BBFF could be crucial to ensuring the best possible accuracy in these important experiments.

This is, by the way, not a measure of how hot the bulb actually gets. It's a measure of how hot you'd need to get to create that color of light from JUST high temperature. We aren't limited to thermal light these days, though, and can approximate the color of "white" light you'd get from higher and lower temperatures using tuned LEDs or various fluorescent stuff.

There are so many different shades of white light bulbs, I am so overwhelmed walking down the light bulb aisle, and then I'm never happy with the one I choose, no matter which one I choose, I get it home and I put it in and I'm like, ugh, I don't like THAT white

Wien's Displacement Law

Introduction Wien’s Displacement Law, formulated by physicist Wilhelm Wien in 1893, explains the distribution of electromagnetic radiation emitted by a black body in thermal equilibrium. The law reveals a fascinating correlation between the peak wavelength of a black body’s spectral radiance and its temperature. Basic Principle of Wien’s Displacement Law The law states that the wavelength at…

Another thing I'm trying to figure out is iterator green lightning

I'm assuming it is due to ionization of some specific gas, but can't really find anything online, other that it naturally occurs in tornado storms irl (but isn't exactly understood why) or info about how do fireworks get their color

Any thoughts on this?

Ionization of a particular gas or mixture of gases was the first thought that came to my mind as well. Low temperature xenon-nitrogen plasma seems to be a vibrant green, for instance. The green sparks are quite strange though, since real sparks are solid material glowing from heat. A compound in the air that heavily absorbs blue light could perhaps turn the blackbody radiation from sparks or high-temperature plasma greenish, and it might even explain the reddish skies beneath Five Pebbles. But the absorption would have to be incredibly strong to have an effect this close to the light source, and the green lightning beneath Looks to the Moon is accompanied by no such reddish hue. Aside from that, the stars in Rain World are green too, which might be related. Maybe our resident astronomer @delta-orionis has a theory for that one?

Burning Bridges

“I am Kalrose, commander of the Second Armada of the Akaviri. We are on our way to a peacekeeping operation in the Pegasus cluster. Humanity is not our enemy, but it will be if you continue to detain us in your piss puddle agrarian star system. Step away from the FTL launcher and no one will die. Remain in front and we will plow through your craft. Either way you will not stop us.”

The human freighter acting as a makeshift gate in front of the launcher did not move. If anything, it centered itself more, in order to better face the Akaviri flagship head on.

Then it broadcasted back.

“Your ‘peacekeeping mission’ in the Pegasus cluster is a genocide. We will not stand back and let you commit this atrocity. We may not have the men or the ships to destroy your fleet, but we don’t need to destroy your fleet in order to keep you from reaching the battlefield. Our piss puddle’s name is ‘Zion.’ In time, you will call it ‘Home.’”

Kalrose barely had time to ponder the nature of that threat when the launcher fired up. The EM readings on his ship went mad, and in that brief fraction of a second, he realized he’d miscalculated. Gravely.

He didn’t know how many thousands of safety protocols had been bypassed, but the amount of power flowing to the gravitational core in the center of the launcher was easily nine times larger than the maximum rating. A micro singularity formed within the space lens, and cladding ripped itself off the hull before spiraling at near light speeds around the artificial black hole.

Kalrose had always imagined such a catastrophe as something like a fireball, reds and oranges, lots of shrapnel and clanging. Upon seeing it in person, he realized how foolish that was.

Red glows were for pokers left in hot coals. This was, for one brief moment, a star fueled on steel. It was never going to be orange.

It could only be white.

The accretion disk condensed further, the energy of the reactions happening near it somehow fueling the gravitational anomaly at the center. His comm system moved into a death scream as the material’s blackbody radiation moved past the x-ray spectrum, pure friction converting the material to energy more efficiently than even a fusion reactor could manage. The heat generated finally caused a full structural collapse, the spine of the station melting enough to wrap the whole barrel of the launcher around the spiraling singularity, twirling it in loops like thread around a spool. The reaction was accelerating now, even without electricity being able to fuel the gravitational collapse, the radiation pressure alone managing to hold the system in a highly fragile state of tensegrity. He recognized the feedback loop that was happening, radiation fueling gravity, gravity fueling radiation, on and on until-

There was no air for noise in space, but he could almost imagine the roar that the expanding cloud of ionized metal should have made as it blew past. There it was. The end of the loop. It had run out of matter to feed on, so without a balance to the compressive force it expanded outwards.

He was fortunate that the explosion was violent enough to atomize the particles. Even a fragment the size of a grain of sand would’ve been enough to take down his flagship. As a lone ion, it could be deflected by the same magnetic field that kept the crew safe during FTL jumps.

He stared numbly at the monitor.

One third of the Akaviri fleet, stranded in a farming system. Not even a shot fired.

He realized that the comm system’s scream had been replaced with the quiet pulse of an incoming broadcast. He accepted it without question, too lost to even be angry.

“Take your time recovering your senses. When you’re ready, just send us a message back. We’re going to need every hand we can on the harvest. There’s no one out there we can reach for help after this. It’s just...Us.”

The surface of the sun is 5,800° Kelvin (9,980° F / 5,500° C) with incredibly high power density.

The thing is while you might not feel thermal effects in a nanosecond, or much visible light, you’ll get a few hundred sieverts of hard ionizing radiation going through you… likely enough to cause acute radiation poisoning which would kill you in about two months.

“What would happen if you spent a nanosecond on the surface of the sun? Would it warm you up, burn you to a cinder, or do nothing at all?”
