Did we just observe potential alien megastructures?
🚨 We found 7 potential Dyson sphere candidates right in our cosmic backyard... Does this end our search here? Or is this the beginning?
In this video, as an astronomer, I will give you a more practical insight into recent breakthroughs, including the discovery of seven potential Dyson sphere candidates and innovative techniques for detecting galaxy-scale technosignatures.
Join me as we unravel the mysteries of the cosmos and push the boundaries of our understanding of extraterrestrial intelligence.

    its already exploded we just need to wait for the light to reach us buddy.......... 7 seconds is enough of a video for me. as i 100% know i will learn NOTHING from this but hearing someone repeat themselves for 8 mins due to ai scripts or bad writing. Edit: I am certain that this video's important info can be summed in 1 min or less

    • @mayukh_bagchi
      @mayukh_bagchi 11 วันที่ผ่านมา

      While I appreciate your perspective, but it clearly shows you are definitely not from a critical thinking and analysis mindset. Yes the video does start with laying the implications and giving background, but even then it certainly will never be less than a minute. As a presenter I have to simplify the concepts as much as possible to incorporate a broader audience. Hence, there are chapter titles for more advanced viewers to skip to relevant chapters. The goal of this video is not to state “the star has already exploded” as there is no conclusive evidence pointing towards that, but rather to break down what the MHD simulations of these giant stars which have branched of their main sequence is actually telling us about their evolution and fate. You are more than welcome to find plenty of 1 minute videos elsewhere.

      ** Correction: The angular resolution needed to spot a 1 cm firefly on the Moon is about 0.000005 arcseconds or in other words 0.000000001388889 degrees. The LSST camera has a pixel scale of 0.2 arcseconds. So no it wont be that precise, but it could spot a golf ball from 15 miles away! My apologies for not spotting this! Cheers!

    According to the known laws of physics there are no black holes. In the 1939 journal "Annals of Mathematics" Einstein wrote - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of General Relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star clusters) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light." He was referring to the phenomenon of dilation. Mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. A time dilation graph illustrates the same phenomenon, it's not just time that gets dilated. Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. This includes the centers of very high mass stars and the overwhelming majority of galaxy centers. The mass at the center of our own galaxy is dilated. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. In other words that mass is all around us. This is the explanation for dark matter, the "missing mass" needed to explain galaxy rotation curves is dilated mass.

    Three comments: don't caption your videos. If I need captioning, I can turn it on in the viewer. Generic music is loud and annoying. Be careful with terminology: typically we don't say frequencies get longer; they get higher or lower, while wavelengths get longer and shorter. That said, I found what you said about surface smoothness to be interesting and informative. OK, fourth comment: too much hype, got annoyed, stopped watching.

    very well explained... I have one question, You cited the references as the name but what if we want to cite the references by number e.g. cite in text as [1-3] and in the bib file we add the references 1 to 3 then how we will do it?

    • @mayukh_bagchi
      @mayukh_bagchi 3 หลายเดือนก่อน

      To cite references by number in LaTeX using Overleaf, create a `.bib` file with your references in BibTeX format. In your LaTeX document, add the `natbib` package and use `\citep` for citations. Include the bibliography with `\bibliographystyle{plainnat}` and `\bibliography{yourfile}`. Compile your document, run BibTeX, then compile twice more to update the references. This setup will produce numbered citations like `[1-3]` and a corresponding bibliography section.
