"Imagine that you want to buy a ticket to see a show. As long as you have a small amount of money in your pocket, you will not get in, but once you have more than some minimum, you will be able to see the show. The more money you have the better your seating might be, but getting into the theater requires you to cross a minimum payment. This is the threshold effect they are referring to."
"The ATLAS team interprets this anomalous evolution as a shift from scattering of sunlight by dust lifted from a reddened surface to the production of small, politically bright icy grains, which changed the opacity of the plume of materials shed off 3I/ATLAS."
"instead likely be temperature-activated and/or threshold process that is being switched on."
Interstellar object 3I/ATLAS changed color from red to green over weeks. Observations from the Very Large Telescope detected increased cyanide and nickel in the object's outgassing. The color shift occurred rapidly and appeared super-linear, inconsistent with simple photon availability or linear temperature response. Researchers interpret the rise as the activation of a temperature-dependent or threshold process that began producing small, optically bright icy grains, altering plume opacity. Avi Loeb described the activation as a minimum-temperature threshold analogous to purchasing a ticket where a minimum condition must be met. The object travels at roughly 130,000 mph and has prompted speculation about artificial origin.
