How An Extreme New Star Could Change All Cosmology

A new white dwarf has been discovered (poetically named: ZTF J1901+1458) that’s doing some stuff that no white dwarf should ever be able to do. In fact, it has multiple properties that are so extreme that it almost certainly did NOT form in the way that we thought all white dwarfs formed. This one peculiar point of faint light may change our understanding of not just white dwarfs, but of all cosmology.

I did my (theoretical) graduate work on white dwarf equilibrium, so this video was particularly exciting for me. White dwarf collisions?! That's so cool! The weirdest thing I learned about them during my grad work was that the vast majority of the electrons are moving relativistically, yet the derivation of the Chandrasekhar limit involves a mix of relativistic and non-relativistic equations. I was never able to figure out how we can get away with that (because I ran out of time and my advisor told me to just suggest it for future research).

Can electromagnetism ever be decoupled? It would appear to me that this would be a logical next step in the decoupling of the fundamental forces; perhaps there is a way of interpreting superconductivity as this?

I think this is something a lot of people don't really appreciate about the internet. I'm 38 so I grew up at first without the internet but it came around relatively early in my life. Before the internet, if you wanted to know something, you literally had to go find an encyclopedia or a book on that subject to learn about it. Now that we have the internet, literally anything you could want to know is somewhere out there and most of it is incredibly easily accessible. This is something that humans wouldn't have even dreamt of for nearly the entire existence of our species but now we have it, and most people don't care, they'd rather spend their time watching stupid tiktok videos or some other nonsense. I find it kind of sad, but that's the majority of humans for you, I guess.

Brilliant video as always! I have a question about the distance measurement though: since we try to measure its luminosity, this is probably done in a specific band/wavelength range. As certain wavelengths will get absorbed and re-emitted in the IR due to gas clouds along our line of sight towards Zee. This is often modelled as optical depth telling us how deep we can look into this cloud. So, which bands are used for such a measurement? PS: did you misspoke when you said the white dwarf becomes bigger after merging, because its mass actually increased.

Another great video. Many years ago when I read about those two different techniques measuring dark energy, coming up with slightly different results, it struck me as an arrogant view point to think such a small difference shouldn't exist. Arrogant to think that the work of both of those teams had such a high degree of certainty, that now we are going to start thinking the universe is inconsistent, instead of question the measurement accuracy of one or both of those teams. On top of that, to this day no one has any clue what dark energy is. Best guess from my point of view is that whatever created this universe has an expansion parameter that gets tweaked. We know that the rate of expansion has varied enormously starting with inflation, then moving forward billions of years, slowing down and speeding up, and no one has any guess why, at least I have not heard any guesses other than my gas pedal guess. Which will always be just a guess, because it it will never be possible to send a probe outside this universe. Even so, I'd bet on that gas pedal parameter still being the best explanation for dark energy 1,000 years from now. It is good to know people are now questioning one of those measurement techniques. Personally, I knew the moment I read that article a decade ago that there was nothing mysterious about that small difference. The only remarkable thing was that using two completely different techniques, trying to measure something that no one knows anything about, that the numbers where still only single digit percent apart. Why even assume that it is possible to nail down the exact rate of dark energy expansion at a particular moment in time? There is an uncertaintly principle that exists in this universe. It is a good assumption to consider the nature of dark energy to be consistent, like gravity is consistent, but I would not bet on it being possible for two different techniques of measurement to give the exact same result looking over distances close to the scale of the observable universe. More likely, one technique is slightly better than the other, and I would go with the CMB number. Love this channel. It is like having an agent with deep subject matter expertise sorting through things in the physics space, so I don't have to, and reporting the most relevant happenings. I plan on doing some of my own interesting projects in the future, leveraging some practical fallout from this whole purposefully designed universe notion. An idea that I realize is probably impossible to prove, but I am not trying to prove anything. Might try to build some things though, starting around 2040 when access to space is cheaper, and asteroid mining gets closer to break even cost wise.

I mean the ramp down in brightness after the initial explosion is what is used to determine the luminosity and this is still extremely uniform throughout all type 1a supernovae. I still think that with this possible implication of an alternate route towards supernova, they will still be used as standard candles, as irrespective of how it collapsed, they all collapse at the chandrasakhar limit.

Hmm, interesting. You hinted If enough Type 1A supernovae turn out to be caused by white dwarf mergers rather than accretion of matter that would effect the result of the 'supernovae' method for measuring dark energy. Might that be in theory enough to make the 'supernovae' and the CMB measurements agree... or would that make the disagreement worse..? Thanks.
@MindForgedManacle 2 жыл бұрын
Seemed to be implied that would bring them closer to agreement. Since the Supernovae measurement would suggest more dark energy that seems to be allowed the the CMB, them being white dwarf collisions would imply less dark energy is needed to explain the current data (him saying "there's too much independent evidence to rule our Dark energy [entirely]" makes me think this is what he means).

I recently watched your videos about how gravity slows time, or rather how slowed time increases gravity, and a question popped in my mind when you mentioned its speed of rotation (1 rotation every 7 minutes) - are these 7 minutes as we experience on Earth and do they match for Zee? Or does the star experience its speed of rotation differently?
@Real_MisterSir 2 жыл бұрын
I believe the rotational speed is relative to our observation - so for our equations then yes it happens ever 7 minute relative to us. But it's one of those weird things we can't fully prove, such as whether light actually has travel time/speed, or if it's merely just what we are able to observe (aka speed of light being a relative term, not a constant).

Question about determining the size of a star: We supposedly can determine this if we know "how much light the star is putting out"/luminosity. But, don't we need accurate distance in order to determine that? And.. aren't our distance determinations a bit...well....possibly flawed? Why does it seem to me like we base luminosity on distance and distance on luminosity when we really aren't positive about either? Is there a way to use red/blue shift of Spectral lines to double check distance?

Isn't the whole point, pun intended, of renormalization to get rid of infinities at particle scales, the electron being but one? Dirac and Pauli were there before the post-war particle crowd? That's a good point though, pun again intended. Black holes are "infinitely dense" singularities that swallow light at their event horizons, so are they a superluminal inflation apparatus too, that inflate into bounded spheres, like the unproven universal inflation theory? They have non-infinite spherical sizes in our 4D universe, though they apparently contain an infinity? That's a bit of a stretch, pun intended, and they, like everything else in our universe, just look like revolving specks of dust in the larger cosmic filaments, that apparently flow like currents, and that we are just resolving now with our newer telescopes including Ligo? The universe apparently, isn't just a homogeneous pool of Brownian motion unstructured entropy? It exhibits twisting swarming behaviours of it's constituents too, seeking a lowest energy ground state while they go with the flow?
