What’s even more difficult to fathom is that the space inside molecules is nearly completely empty. The reason you can touch things is because of the electron shells of atoms repel each other.

How is it possible for us to not be moving through space but instead set in space while the universe continues to expand AND be on a collision course with the Andromeda Galaxy at the same time? That always baffles me.
What's more important: remembering what you're taught, wasting time on abstract ideas, having a moment of incredible clarity, crunching data getting the right answer... why and how people come up with these answers more so questions, is hard to fathom but love the intake on this stuff
Great Video thank you just want to point out the image of an elliptical Galaxy was actually a spiral Galaxy viewed from the side. An elliptical Galaxy looks more like an egg shaped swarm of stars with no defined structure
While Andromeda is the largest 'close' galaxy, there are several dwarf galaxies that are much closer to the Milky Way. There also is evidence of former galaxies that are now part of the Milky Way.
Man I am so happy to see Mike back!!! The last video I saw of List 25 was when they were saying good bye to everyone. The channel wanted to go in a different direction and they weren't part of it. I wish I could remember the other guys name. But since Mike is back now, I'll subscribe again. Also I wonder how many people unsubcribed like I did and don't know he's back?? I have to go back and see how many videos and how long ago he came back now. Glad to see you Mike.
#23 is a misconception. It's true the universe is expanding, but that refers to the space between the galaxies. The space within galaxies themselves is not expanding. The stars we see when we look at the night sky are all inside the Milky Way. They will always be visible.
Also, the current thought is that the gravity of the Local Group of galaxies will keep them together because it is strong enough to counteract the expansion.
To display the fact that dark energy and matter exists, the BBC television series The Sky At Night showed a bowl of mostly dark jelly beans, with only a tiny amount of light ones in the bowl. That's a good way to demonstrate it. Then add this idea from me, imagine that the the light ones glow in the dark and you're sitting in the bowl, because it's gigantic.
With the ever-expanding universe, I'm still surprised the constellations we have today resemble what they do. Wondering how long until they too change to the point where our Descendants call them by another name.
the rate of change in the aspect of human lifetime is minute, like .000000000000000000000000000000000000000000000000000000000000000000000000000001% & that's generous.
I know this comment has nothing to do with this website, but I am posting it everywhere. I, as a Christian American, stand with Israel!!!!!!!!!!!!!!!!!
Irregular galaxies are galaxies that have collided with each other. Often the tidal forces are what makes them ‘irregular’ as things are whipped around due to gravity. Also, the Milky Way has cannibalized other galaxies, the remnants of the large and small Magellanic Clouds are proof of this. Also, much of the universe has expanded so far beyond the horizon that the space in between us and them is so great and so far that the universe is expanding faster than the speed of light. We will never see them. Eventually, everything will be beyond it (as you touched on). Sun contains 99.5% of the mass in our solar system. We receive radio signals typically due to black holes, pulsars... and anything else that produces em energy, however, pulsars are the most regular.
#17, Milky Way ate up a dwarf elliptical galaxy called Omega Centauri or C80 in the Caldwell catalog. It is the largest by far known Globular Cluster, but it is big, too big at 15 light years across and 10 million stars with a probable black hole at its center. Many astronomers think it is a captured dwarf galaxy and has lost some mass through several orbits through the disk of the Milky Way.
Great stuff. I never understood how people get so worked up (nervous) about not knowing about space. Nor have I understood how, like he said, the greatest minds go mad at….whatever thing they are chasing Just go with the flow baby. We aren’t going to know everything
Me, at the beginning of the video: please mention supermassive black holes. 15: black holes are at the center of every galaxy Me: Be specific! Pauses video, "Play Supermassive Black Hole." Crappy cover version plays. Me: Damn. Guess *I* should have been specific.
A guy I dated in my youth told me that the way to tell the difference between stars and planets in the sky is because planets don't twinkle. He's crazy, of course - they all twinkle, and when I pointed this out he told me I didn't know what I was talking about. I've been into astronomy since I was 10 years old, so I know the difference between a star and a planet because I know where the planets will be visible in the sky. Needless to say, this guy didn't last long after this. The one I eventually married asked me what I was reading about in that month's issue of Astronomy Magazine, and I told him, "gravitational lensing," and he actually knew what I was talking about.
That bit about planets not twinkling is one of those old tropes my dad used to espouse, like using butter to soothe a burn, or that - like Anakin Skywalker - the moon has a dark side. Are you old enough to remember the canals on Mars? I was 15 when Mariner 4 did its flyby, & eagerly stayed up late one night to see the 1st close-up images it sent back. How disappointing it only revealed craters! We've learned so much since, but it hasn't yet trickled down enough to wash away a lot of that folk "wisdom". Gravitational lensing, yes! But I'm still struggling to understand - really grok - Lagrange points. Modular arithmetic, too.
@lesnyk255 But...butter does soothe a burn. And...are you saying the moon _doesn't_ have a dark side? I'm not sure if you're being facetious, but if in the future, anyone reading this burns themselves...butter will absolutely ease the pain.
@@joeroscoe3708 I'm not being facetious, but I assume you are. And in case you're not, I assure you from personal experience that butter does NOTHING to ease the discomfort of a burn. If you don't believe me, ask your doctor. And because the moon always keeps one side facing us as it orbits around us, the far side - the one always facing AWAY from us - gets just as much sunlight as the side we can see. Sure, it's in darkness half the time - but so is half of the Earth. We call it "night".

Stupid question #2. If we don't know where the end of the universe is (because we don't have powerful enough telescopes) then how do we know there aren't older stars out there older than what we believe the universe to be?
they are saying now the universe is much older than the 13.8 billion years mentioned here which only adds to the mystery of how it all started ,,,very good video and very well done .seems no point in trying to understand it all as we will never know.Just make the best of our short time here.
Hey Mike, just wondering will there be any appearances by Tristan, Hope or huan at all in the near future. If not, do you still keep in contact with them and know ehat they are up to these days?
As far as Tristan goes I'm not sure. Hope moved out to California and Juan moved closer to Tampa, so I doubt it. I do speak to Tristan and Juan every so often but, Hope if I'm being honest was more of Tristan's friend so I actually haven't heard from her personally in a while.
#16 misconception. On a 2015 study our galaxy is 150K light years and on a 2019 study the Andromeda is only half the mass of ours. And on a study of that same year, our disk is approximately 200,000-265,000 light years using the Chandra, Gaia and Hubble telescopes. The 100,000 LY is that old estimate by Shapley due to our telescopes not as powerful at that time. Even wikipedia underrated our galaxy at 87,400 LY. And the universe fast expansion speed might be an illusion due to our location in the cosmos and our universe is indeed expanding at a much slower pace.
Please dont confuse people that sound waves and radio waves are the samething. Sound waves are compression of air. Radio waves are electromagnetic radiation.
In the future you will still be able to see all the stars. This is because the only stars we see at night are in our own galaxy. Infact when Andromeda merged with the Milky Way we will be able to see even more stars
If we can only see 5% how do we know the age of the universe if we get the number by measuring observable galaxies? And we can't extrapolate if the universe is expanding.
Yeah makes no sense, the universe could be trillions of years old but we can only see 13.8 billion light years because of the limitation of the speed of light.
The universe has to be far older, after all, the heavy elements wouldn't have existed right away, they would need to be made in supernovas and scattered across the universe for us to have any.
[Last one promise] My answer to #11? "We [the collective, we] screwed up "Something" with the planet [something being whatever you think this, means], past the point. Like Prince said, "OOPs, game over".
The no star thing. We're in a galaxy that's held in place like our planet to the sun. Wouldn't it be other galaxies not visible but our own still will? Something isn't adding up

Because we are both in a localised group and Are relatively unaffected by this expansion, which is universe wide.
