What ingredients do you put in your galaxy clusters? 🤔⁣
⁣
Galaxy clusters, like the one in this image, have three main ingredients: individual galaxies, multimillion-degree gas that fills the space between the galaxies, and dark matter. ⁣
⁣
A team of astronomers used a set of @nasachandraxray observations of this Coma galaxy cluster to probe gas properties and learn about the viscosity of the hot gas in Coma.⁣ ⁣

incolius @astronom_guy I see what you are getting at but you seem to have made an error and I'm wondering if you actually understand it yourself. In your room example; if you measure the temperature of the room the room (if in space with no other heat source) will be 2.7 Kelvin (-270 Celsius). While the single particle in the room will measure as being whatever the temperature it is. Might still be 2.7K as moving through space even really quickly doesn't actually generate heat nor energy as there is no resistance in space. Heat is not actually energy, it is the resistance or friction of two molecules with each other that generates energy which in many cases is output as heat. This heat can then be measured as a temperature. The reason for my question which it you understood space thermodynamics better is that heat doesn't transfer well in space due to the absolute 0 temperature of space (2.7 Kelvin) and because of the lack of atmosphere. It is a vacuum afterall. Thus the influence of the temperature of one thing in space won't always influence the temperature of another. It all depends on how dense it is and how long you come into contact with it. Thus my question about this kind of hot gas cloud in space. It is hot due to the chemical reaction in the cloud being very active and thus creating a lot of friction, thus high energy output thus high heat generation. But if it is not dense a spacecraft can fly through it without melting. But if it, it could absolutely melt the spacecraft. Thus my question. Was just hoping for an answer from someone with more knowledge ?

astronom_guy @incolius I repeat. Temperature and heat are not the same, but of course they are binded. Temperature is linked to the speed of the particles, molecules..., Heat is an energy. Take a room without air unless one molecule traveling at very high speed. The temperature of this room will be very high, but the heat of this room will be very low. You will freeze there. Same in space... And I repeat again : see Internet for more informations...

mustafakemal.ayan Aşığı, aşk sürecinde en çok zorlayan, katlanması en güç durumlardan biri kıskançlık ateşidir. Sevgilinin ilgisinin kendisine yönelmesini isteyen âşık, bu gerçekleşmediği ve bununla birlikte sevgilinin ilgisinin başkasına yönelmesi karşısında bu duyguya kapılır....Buda sende bir sevgili değişten için ondan sonra kıskanclık başlar ben rahatım.Kıskanç olma. ne için kıskanç oldugunu biliyorum. o kıskançlıgın içine beni sokma ayrı tut.

incolius @astronom_guy I'm not sure the point you are trying to make. The way we express heat is through temperature. Your answer has 0 bearing on my question. In the way I worded my question I could have used heat or temperature and the question would be unchanged. Heat is the state of the molecules while temperature is how we measure/express that state.

astronom_guy @incolius Sorry for you, but what you say is false. I invite you to read some physic books if you don't want to look in Internet...
