The Secret World Of Black Holes - Dr Becky Smethurst
5:25when stars die and we find them across our entire galaxy you know there's probably Millions to billions of black5:31holes in our entire galaxy right now that are somewhere around like 10 times the mass of the Sun something like that5:50center of every single Galaxy every island of stars in the universe of a trillion Stars there's this super
Joe Rogan Experience #2506 - Michelle Thaller
1:42That the Milky Way galaxy would be as large as the Earth itself.2:00thing. So if that's the size of a dot of an eye on text, then the galaxy would be the size of the earth. That's when people's eyes get big and people respond to it.2:19that dot of an eye, then the Milky Way galaxy would be bigger than the Earth.
The 3 Body Problem, Aliens & How The World Ends - Dr David Kipping
16:45an a multitude of things that we can discover out there the Galaxy alone has a hundred billion stars in it and33:30part of the Galaxy maybe even our galaxy itself like where which aspects of this are special and which AR um for example35:53say therefore the probability of Life somewhere in the galaxy is very high because if the probability is say

The Biggest Sneakers Releasing in 2025 | The Complex Sneakers Show
Jool Luma and Brendan Schlub discuss the most anticipated sneakers of 2025, highlighting a trend of Nike and Jordan Brand re-releasing iconic 'vault' shoes like the Undefeated Jordan 4s, Galaxy Foam Posites, and Air JordsummaryThe 2025 sneaker landscape is heavily defined by retro releases of 2010s grails (Undefeated Jordan 4s, Galaxy Foam Posites), raising questions about whether this strategy will resonate with a new generation of sneakerheatakeaway“If the Galaxy Foam Posite sits, it's going to be a tough pill to swallow... If they come out and they're like the LeBron South Beach Eights, well, I feel like South Beach Eights... was one of the few ones that was able quote
Do we need a new theory of Gravity?
The video analyzes the scientific debate between Dark Matter and Modified Gravity theories, concluding that while Modified Newtonian Dynamics (MOND) and Emergent Gravity explain galaxy rotation curves well, they fail to summaryMOND (Modified Newtonian Dynamics) accurately predicts galaxy rotation curves by modifying gravity at low accelerations, but fails at galaxy cluster scales and cannot reproduce cosmological data like the Cosmic Microwavetakeaway“Gravity-based ideas tend to do really well on that first part [galaxy scale regularities]... they run into a lot of difficulty when you move into that second part [the grander cosmological scale].”quote
All About The New Telescope NASA Just Launched, with Jason Rhodes
NASA scientist Jason Rhodes details the Nancy Grace Roman Space Telescope's mission to investigate dark energy through three primary methods: supernova surveys, galaxy clustering, and weak gravitational lensing.summaryThree Measurement Techniques: Roman measures dark energy via (1) supernova standard candles to track expansion over time, (2) galaxy clustering to see how gravity and dark energy compete, and (3) weak gravitational lensitakeawayMicrolensing for Rogue Planets: Unlike transit methods that find planets near stars, microlensing allows Roman to detect free-floating 'rogue planets' by observing light blips when stars pass in front of background starstakeaway
The origin of galaxies – Malcolm Longair 1990 Christmas Lectures 4/5
The lecture explains that galaxy formation is driven by dark matter, which allows structures to form before the universe cooled enough for ordinary matter to clump, resolving the discrepancy between the smooth cosmic micsummaryDark Matter Necessity: Observations of galaxy rotation and cluster dynamics show 10-20 times more mass than visible matter, proving the universe is dominated by invisible dark matter.takeawayGalaxy Formation via Collapse: Galaxies form through a 'cosmic cycle' where massive stars (60 solar masses, 1 million year life) die quickly to recycle elements, while low-mass stars (<0.1 solar masses) cannot ignite fustakeaway
The Secret World Of Black Holes - Dr Becky Smethurst
Supermassive black holes do not hold galaxies together; galaxies are held together by self-gravity, and removing a central black hole would not cause the galaxy to disperse.takeaway“If you remove the Sun from the center of the solar system... all the planets would just fly off... In a galaxy the black hole is not even 1% of the entire mass of the Galaxy... if you removed it nothing would actually hquote
