Arguably the most likely way we will first discover alien life on another planet will be using the power of atomic spectroscopy. You can grab the Map of Quantum Physics here store.dftba.com/collections/d...
Aliens will most likely leave a tell tale trace of their life in the atmosphere’s of their planet. But how do we know what chemicals the atmosphere of a distant planet contains? The answer is atomic spectroscopy. If we see a planet passing in front of it’s star, some of that starlight is absorbed in a very specific pattern called an atomic absorption spectrum. Each element has a specific pattern like a barcode, so through careful analysis of the light it can tell us which gasses are in the atmosphere and their proportions. We already use this technique for other space objects like stars and nebulae, measuring properties like temperature, density, ionization and relative velocity. This is a gift that nature and quantum physics has given us and the majority of what we know about the universe is based on this technique.

Quick question from a struggling uni freshman: why did you major in chemistry and what do you hope to do with it in the future?

@maliciousmarka 3 жыл бұрын

TheZarcFiles Hey pal. First and foremost, just know that Uni is a great place to be. You won’t know it at first, but the people you meet and the things you do will be the best things you’ll experience! As for why I took on Chemistry, the short answer is that I love it and it’s the course where pieces fit together perfectly in my head. I only realised this in my last year of College. Finally, I look to get a PhD first, then move onto working at Google. I know it sound weird, but a lot of people don’t understand how Chemistry can branch into Finance, Tech and the rest of the Sciences due to the problem solving skills you gain. (Google because I’m a bit of a tech geek myself😊). Hope that answers your questions, and I wish you luck on your Journey👍

A good way to visualise it imo is to imagine ocean water as a 2d slice of a 3d wave. For light, if there were only one source it would be a perfect sphere in the EM field.in our daily lives, though, with multiple sources of light and matter for it to refract and reflect off of its likely that the entire field is a chaotic mess of peaks and troughs with orderly patterns appearing along straight line paths

For 80 years we have tried unsuccessfully to determine if life ever existed on Mars. If we can't confirm whether or not life exists or ever existed on a planet in our own solar system, don't expect any definitive answers regarding life existing outside of our solar system.

@dread46 3 жыл бұрын

Well, Mars has barely any atmosphere to begin with, also he was talking about having enough bacteria or higher life forms on the planet to actually make a difference in a 'usual' atmospheric composition. So this scientific method not showing any results on mar5s means there is no copious amount of lifeforms, but doesn't mean there isn't any at all. :)

This is by a large margin the best concise video explaining it. I love science so I had those words in my vocabulary, but did not quite understand their relations and origins. Thanks for that! Sad to see it does not have much views, this is a pillar for further understanding of the conclusions we get and, of course, the universe itself.

Why is uranium reactive but gold is not? I understand gold is relatively inert because the nucleus is big enough that the electrons approach light speed. So what about even heavier elements ?

@sergitorres8158 3 жыл бұрын

Why does a solid emit a continuous spectrum and a gas only a discrete one? I mean, if the thermal radiation comes from accelerating and decelerating charges due to thermal motion (right?), and the thermal velocities spectrum in a gas is continuous (maxwell-boltzman distribution), shouldn't the radiation spectrum emited also be continuous?

@domainofscience 3 жыл бұрын

Yeah interesting question. I'm just thinking this through: light (electromagnetic radiation) comes from the oscillation of electrons. Oscillation is the important concept here. So yeah, in a hot solid you have atoms with electrons attached vibrating in a large distribution of vibrational modes leading to the thermal spectrum. In a hot gas, the thermal velocities do follow the Maxwell-Boltzmann distribution, but you don't get the continual oscillations. For a gas particle their interaction times are very short compared to their free flying time. I guess you would get short pulses of EM radiation each time you get a collision of gas particles but the energy of this is so much lower than the source spectral lines (which come from an entirely different process to oscillations) that it probably looks like a noise background. So yeah I think your intuition is right. I wonder if anyone has measured this?

@sergitorres8158 3 жыл бұрын

@@domainofscience Thanks! You are talking about Bremsstrahlung, and yes, is much weaker than the light emitted due to deexcitation of electrons. Let's supose we have a gas at 3700 K. Then, it's black body curve peaks at red, and a red photon has around 2 eV. On the other hand, if you compute kT at that temperature, you get less than 0.5 eV. So even if you stopped the particle completely it wouldn't have enough energy to emit that red photon. Particles accelerating due to collitions don't seem enough to explain a thermal spectrum... so why does the sun exhibit one? It's gas and plasma, it cannon have any colective vibrational modes like in a solid. Where does this "extra energy" come from to explain a thermal spectrum? I haven't found a satisfactory answer to this, and I've been looking for months. I don't really understant where does thermal radiation come from. I would like to discuss with you some topics about thermal radiation and rayleigh scattering (for example, the role that resonant frequencies in the atmospheric molecules play in the fact that blue is more scattered than red, rather than particle size compared to the wavelenght of incident light). If you are interested, we can exchange ideas! email me: sergitorres17@gmail.com And thanks for replying, apreciate it.

@thomasvandijk87 3 жыл бұрын

Oxygen is very reactive, meaning that the supply of O2 molecules will dwindle over time, as the molecules react with other substances such as minerals and metals. Therefore, only a steady supply produced by living things can sustain atmospheric oxygen for extended periods of time.
