Why Neil deGrasse Tyson and Emily Rice Think You Should Pay Attention to Low-Mass Stars

[@StarTalk]

What other questions do you have for Emily?

[@Pennsylvania2A]

We need to look at the true danger out there. What's being done towards comet & asteroid deflection planetary defense? Thanks guys

[@byenzer5101]

So, if BIG stars have short lives, and NEIL is a BIG star, then??????

[@michaelccopelandsr7120]

Yes, can you get Neil to help with IAU in changing the stars? Let's change the stars. What I mean is, get the IAU to, OFFICIALLY, make a new constellation. My idea for changing the stars includes Orion, Taurus and Pleiades (Subaru). Figure it's time to put something up there that's relevant to us, don't you think? Take Orion's belt and "Betelgeuse" becomes the head with a baseball hat. The 3 stars of Orion's belt make up the 3 fat belt loops on a baseball uniform. Below the belt are two legs bending at the knee. "Saiph" is the back foot and "Rigel" is the front foot. The spear pointing at Subaru/Pleiades is the bat and Subaru/Pleiades is the baseball flying away after being hit. "Bellatrix" is the hand that let go and "Aldebaran" of Taurus is the bat's tip. Put it all together and you get, "THE ALL-STAR." In my case, I see a left-handed batter with a, "7," on the jersey. Which makes him, "Mickey." (As it should be) But you can put any number you want, making, "THE ALL-STAR," any player you want. Pass it on, please and thank you. Don't worry, where I come from, crazy is a compliment. ;-P

Anyone know if laminar flow in plasma can compress specific gravity of its container? My idea is to streamline the flow of plasma to the point of increasing specific gravity in a similar way to wrapping the object in question within a "subsoace bubble" or more functionality making the object more easily slip through any ambient fluid, be it water or air in the atmosphere or interplanetary space. The idea is to get twice the speed for half the energy input so a pseudo-gravity drive of sorts.

[@plutogd2006]

Me and my friend, Michael, were bored in our class, so he had the absolute genius question of "I wonder how many bananas it would take to cover the largest star." So, we got to work. We found that most sources said that UY Scuti was the largest known star, with a radius of 1.118 billion kilometers. So, we had to convert the kilometers to meters, multiplying by 1000. But, a banana is a meter long, so we had to multiply by 100 to get the radius in centimeters. After this, we looked up the average size for a banana (15-20cm) and used the number in the middle (17.5). So, we divided the radius of the star by the average banana and, before plugging the numbers into the formula for surface area (4πr^2) and we ended up getting 157.6 nonillion bananas. After this, since we decided we could take this further, we found the amount of bananas it would take to equate the mass of UY Scuti. We found the mass of UY Scuti by looking up the mass of the sun (1.989x10^30) and multiplying it by 30 since the source said it was roughly 30 times more massive and then multiplied it by 1000 to get it from kilograms to grams (which we calculated it as 596.7 undecillion). Then we divided by the mass of a banana (we found it to be 180.56 grams) to give us our final answer of about 3.3 undecillion bananas. These are probably wrong, but we had a lot of fun doing it. Though, we now wanted to find how much you'd have to crush all those bananas until they became a black hole. I'd assume it'd be about the same size as UY Scuti's schwarzschild radius, but I don't know for sure. Could you help us understand how you'd calculate that because to find the gravitational constant, you need the gravitational force, and for the gravitational force, you'd need 2 objects according to what we were seeing. Also, thanks for inspiring my love for space and I'd love to watch some more awesome videos about black holes. :)

[@augustwest9727]

Wouldn't you find the mass of the smallest black hole and then the mass of your average banana...

[@plutogd2006]

@@augustwest9727 I don't think I'm understanding what you're saying, could you elaborate?

[@vincenthopkins6345]

​@@augustwest9727 How would you be able to find the mass of the black hole?

[@augustwest9727]

We already know what the smallest black hole we've found is. So that would be a reasonable basis to start collecting bananas...

[@plutogd2006]

@@augustwest9727 I think I might understand what you're saying. If you're talking about shrinking the bananas individually down into Blackholes, that wouldn't be efficient because you lose mass between Blackhole combinations so you'd need more to make up for the mass lost. I'm not sure what the rate of mass lost it exactly, but I can give an example. If one Blackhole with a mass of 80 kg eats another blackhole with 80 kg, you'd have one Blackhole that has a mass of like 156 kg or something like that.

[@brian1204]

Can we really know how old the far galaxies and the stars within actually are? Yes we have models that estimate them based on the estimated elapsed time the alleged “big bang” (and yes I do understand that we have lots of evidence supporting the idea) but it seems to me that we are still missing something essential. I look forward to us learning more about those things we don’t fully understand, although I honestly don’t think it will be in my lifetime (I’m 67 at the moment) to the extent that we know what it is that we currently call “dark energy” and “dark mass”.

[@moonshoes11]

I’m fine with having a tentative position based on the best available information, knowing it can change. ✌️🍎

[@brian1204]

@@moonshoes11 sure, it is the best available fit for what data we can confirm. I’m sure our models will change as we learn more. I am very interested in learning what precisely “dark matter” and “dark energy” are. Right now they just seem like a “placeholder” for what we don’t yet fully understand.

Can a hot jupiter produce fusion if its internal temperature is increased by its close proximity to its host star?

[@lethargogpeterson4083]

I doubt it. I don't know details, but I know that the fusion even in stars is in the cores. By the time you get to the Sun's surface, for instance, that is not where the fusion in the sun is happening because it is not hot and dense enough. Therefore, I doubt that even a really close planet, which is still farther than the surface of the star, would get hot enough.

[@concord5859]

Is there really such a thing as rotation? By "really" I mean when you take it down to fundamental principles?

[@lethargogpeterson4083]

As opposed to just an expression of more general physical laws, but in a rotating frame of reference? Is that what you are saying? I wondered the same thing a long time ago when I took college physics classes. I didn't get an answer but I think I understand the question. I still am not positive, but you might find some interesting stuff if you look up spin, as in quantum spin. Good luck.

When they explained"Degeneracy" it reminded me of someone trying to explain the Postulated state of Quantum Superposition."we can't say it is this or that because it can actually be something which is both this and that, at the same time". Odd that is, but whereas Quantum Superposition may actually just be a "Mathematical Artifact" arising from our lack of knowledge, "Degeneracy" is a description of a "Real" observable Phenomena.

If there is no difference, then why lump them in a category with rocky/terrestrial planets and not make them a sub category of star? Perhaps it’s best I put my $5 where my mouth is in Patreon.
