About This Club

The name explains it : This club is meant for discussions of any sort of physics, chemistry, biology, geology, astronomy, whatever science you want you comment about. This might be a good place for sharing hypothesis or complete theories as well, so suit yourself and imagine all the crazy things you can imagine, science knows the way! Anyone may join, however the privacy is set on 'closed' to avoid spam, hopefully this will keep that at bay. Upon entering the club, I strongly encourage you to write a short introduction to tell others about what your interests in science are and what experiments you've made happen (if you have), and of course, if you're working on any project/hypothesis that needs discussion, this will be the place too.

    While I'm excited to see people working on these sorts of things I have to say, ESA, you need to work a bit harder on picking your names.

    Not quite The Expanse but good practice for converting all those other dwarf planets in the outer solar system into habitats. If the field of such bodies extends out into the Oort cloud as well then we have a LOT of habitat-building to do. https://arxiv.org/abs/2011.07487

    This is painful to watch. I just hope this is the catalyst for building a new radio telescope that's even better.

    That's being worked on too. A fully-fueled Starship in orbit is halfway to anywhere in the solar system. Speaking of which, there's currently something of a 24/7 watch on Elon's little Boca Chica project at the moment. They've done a number of engine test-firings with the Starship prototype (serial number 8 ) in the past couple weeks and the FAA has given clearance to 15km altitude for the next "hop", which is expected to happen any day now. Elon has said there's about a 1 in 3 chance of everything going smoothly. We'll see. Should be exciting either way. And after that there's

    I considered that actually when the Pluto flyby happened and we saw that Pluto had an atmosphere. That said, I think we should focus on getting established on Mars first before we dream too far ahead. Right now all eggs are in the Blue Planet's basket and a single planetwide extinction event will end us all. One colony at a time

    "There is a case that habitability on Pluto may be just as good as on the closer icy moons. In fact, if Pluto is the standard for dwarf planets found in the Kuiper Belt generally there may be many more habitable worlds out there." https://youtu.be/GMIbZ2k_OtQ There's a lot of real estate out there in dwarf planets too. Even just in our Solar system there are hundreds of known dwarf planets, and probably hundreds more that we haven't seen yet. (Even Hubble couldn't see much further than the inner bit of the Kuiper Belt.) Yes, I said hundred

    Looks like the cabling situation is more precarious than realized, meaning it is no longer considered safe to repair the antenna as was first hoped.
  14. efaardvark
    Ok, so not a lot of astrophysics or science in this one but I thought it was cool nevertheless...

    “The TAGSAM head performed the sampling event in optimal conditions. Newly available analyses show that the collector head was flush with Bennu’s surface when it made contact and when the nitrogen gas bottle was fired to stir surface material. It also penetrated several centimeters into the asteroid’s surface material. All data so far suggest that the collector head is holding much more than 2 ounces of regolith.” So much in fact that the plastic flap that was supposed to close and seal the sample inside is stuck open, leaking the material that was collected inside the TAGSAM head.

    LIGO and Virgo gravity wave detectors detect biggest wave to date. “The new signal likely represents the instant that the two black holes merged. The merger created an even more massive black hole, of about 142 solar masses, and released an enormous amount of energy, equivalent to around 8 solar masses, spread across the universe in the form of gravitational waves.”

    16 Psyche to be precise... “The Psyche mission will be the first mission to investigate a world of metal rather than of rock and ice. Deep within rocky, terrestrial planets—including Earth—scientists infer the presence of metallic cores, but these lie unreachable below planets' rocky mantles and crusts. Because scientists cannot see or measure Earth's core directly, Psyche offers a unique window into the violent history of collisions and accretion that created terrestrial planets.” This ought to be a cool mission.

    Interesting article in Astrobiology mag... Photobiological Effects at Earth's Surface Following a 50 pc Supernova
  23. efaardvark
    That reminds me of another one... A biologist, an engineer, and a mathematician were observing an empty building. They noted two people entering the building and sometime later observed three coming out. The biologist remarked, “Oh, they must have reproduced.” The engineer said, “Our initial count must have been incorrect.” The mathematician stated, “Now if one more person goes into the building, it will be completely empty.”

    Having studied astronomy this is pretty funny This is not really a joke, but I still think it's pretty funny
  25. The dummy system
    Ah yes I remember seeing this video when it came out. It is pretty neat! Ever since I discovered the nature of chaotic systems I've always been intrigued by them and their connection to seemingly unrelated mathematics.

    TFW you rotate the mandelbrot plot through the third dimension. Kind of like a Flatlander being visited by Mr Sphere.

    Geology is without a doubt one of the fields I find most intriguing, personally. It seems to be very much related to astronomy. I believe I've watched the PBD documentary before, they make up possibly half of the total of documentaries I watch every week, hehe. What inspired you first you study geology in particular?

    Seeing how it was requested you share some history of yourself/any projects you've worked on and what not...well unfortunately I am not really qualified, I suppose, to be here That being said I do have vast interests and enjoy these sorts of discussions, and thus far have really enjoyed reading previous topics in this club. Soo a bit of background - I was basically a third year Geology student (2.5 years in) until oil and gas tanked in Canada and then just quit school. I have the option to go back but haven't decided (long personal excerpt could go here but I won't bore you).

    Oh wow, the animation! How cu...u...ttee? 0_0;;;;;;; Bye bye earth. Hello nuclear winters. This video made me start thinking about if Yellowstone exploded and the ash fall that would basically consume most of America and south Canada. Add in wind. Funtimes. Also, I enjoyed how they pulled a rubber duct from the rock bedding.

    Ah I see, so it is actually freezing yourself. When I heard it I thought like putting yourself in a freezer and thought that this couldn't be it (well the AC is kinda that way) ('freezing' is also used in behavioral science to describe standing still, just fyi). It sucks that you don't get those for free though. I always heard about problematic cases with healthcare in the US but didn't realize it actually comes down to such a concrete level. Back to topic though, a relative of mine says he has seen one years ago but wasn't able capture it on a device. I don't think I'll see one with th

    Well, the application of cold will reduce swelling and that will reduce pain (or flat out numb your nerves). I managed to get myself so cold between the freezing temps and keeping the ac on in my car on top of that to be a block of ice, even after I went to work later. The room I work in, usually cold to me, felt like someone had a furnace in there that day. Numbing by freezing has worked for me many times in the past too. And, healthcare in the US is complicated. If you have insurance, you still have deductibles to meet, copays for the visit, and may have to pay a portion of the
  44. Illusion of Terra
    Holy moley, that is one bright flash. I can definitely say I haven't seen that. This is not on topic, but I don't understand the part with freezing yourself out of pain. By freeze you probably mean the freezing behavior, not getting colder?, but how exactly is that related to pain? Also, aren't those drugs covered by health insurance in the US?
