Galaxies Don't Rotate The Way You Think | 4K 

I heard that the late US Senator John McCain's mother died this October at 108. She was alive during the Spanish flu pandemic! Is that nuts or what? A remarkable family, she had an identical twin sister who lived to 99. father to 97, and mother to 87! Maybe not so nuts??? I'm only 4 years behind you and I can't keep up with everything I want to know. Plus, I grow more fascinated with science history year by year. It's a losing battle!

@@FlyingSavannahs So true- it seems our scientific knowledge is increasing exponentially every year! Although the internet has a lot of drawbacks, (as I'm sure you agree) it has the benefit of making access to this knowledge much easier. It's also great for keeping the mind healthy!

Get Elite:Dangerous and fly a ship to the center of the galaxy and land on a planet. You will see how epic it looks.

Isaac Asimov’s Nightfall.👍

It would look generally the same, a bit more stars but thats it. The number of stars we can see in the night sky is a INCREDIBLY small fraction of the stars around us (relatively) in the galaxy. The sphere of stars that we can see in the night sky would be a minuscule dot on essentially any rendering of our galaxy. This region is about 20 light years in radius... but our galaxy is roughly 100,000 light years in radius. So the region is relatively incredibly small. So in the inner galaxy, there would be more stars in this small region but thats about it. Although there are vastly more stars in the inner galaxy, the increase in the amount within a 20 light year sphere would be more, but not so much more that it would look different. And you also might think well these stars are going so much faster, thus the stars positions wouldbe changing as well. This too, would not happen. Yes the stars are orbiting much faster in the inner galaxy, but the reason the stars in our sky stay fixed is because all those stars we see are local (within the 20 ly radius) and thus are moving WITH US around the galaxy at generally the same speed and direction. So just as the cars in a formation lap around a racetrack dont move relative to each other because they are all going the same speed, the same is true of our sky and the stars positions in it remain constant, at least over thousands of years. This would be true of the inner galaxy too, although faster, the relative speeds are still similar and thus the apparent positions of those stars would remain seemingly fixed.

@@Ddub1083 One small change. The stars even in our local area are still moving relative to us. People just don't realize how long 250 million years really is. Try drawing a really big circle on a large A1 paper. Now divide it into 250 million sections. Yea, not going to happen. A single dot of a very fine pen would already be more than 1 or even 100 sections. So the stars are still moving, it just takes far longer than our lifetimes for it to be noticeable with direct observation.

Or imagine being in a rouge solar system (if there is such a thing) that has been ejected from its galaxy, and having the galaxy fill your night sky.

I still think "dark matter" and "dark energy" it's just a crude explanation for their (human race's) complete lack of understanding. They can't find any of these particles that somehow make up 97% of the universe.

@@bwxmoto That's pretty much how it is at present. How would you characterize your knowledge about an animal you've never seen directly but have found the nests that it makes, the food it eats, the traces of where it travels, and what sounds it makes. Now draw a picture of what it is! Tricky, that.

@@FlyingSavannahs In that analogy they would be talking about ghosts and how the ghosts move things around your kitchen at night. They don't even know if it's an animal in that analogy, and the nests it makes might be things the earth or wind is doing and not an animal making the nests at all. But then they proclaim boldly it is an animal. LOL. I'm not buying it.

Dark Matter exists. That's just what we call it. They just don't really know how it works. They know it's there, but not much about how it functions or what it actually is.

@@w0y4k15 They don't know jack about it. They say they know it exists. That's what I am calling into question. I know all the studies and explanations. I have seen the evidence. I have even seen how it affects light as gravitational lensing appears to go through clouds of dark matter where there is very little actually matter inside the clump of dark matter as it travelled through another galaxy. I still think they do not have a clue about what it is or even if it exists at all.

wow has that "yooooo" mirror guy on tik tok heard this one ?

That's fascinating. For the binaries, are they so close that both stars would be considered in the same solar system (like within a hundred AU of each other or so) or much more distant, so that each has its own distinct solar system?

But they become single

@@rustyshackleford9475 well, they're not young anymore

Negative mass .

Yeah, lets hope the breakthrough happens in our lifetime. What a great time to be alive, when science discovers new knowledge everyday and we could follow the development with a touch of our finger.

This and interstellar travel. Man, I really wish to see images from other solar systems in my life time.

I think Alex will figure it out and explain it in an upcoming feature video in 2021!

@@eddiebrown192 Actually negative mass would defy the laws of conservation of energy because of the way it would interact with gravity. Negative mass would be propelled by positive mass, as it has reverse gravity, but positive mass would still be attracted to it, so the two would essentially chase eachother down at an infinitely accelerating rate, creating infinite energy, which obviously isn't possible. This is how its known for a fact that negative mass can not exist is any way. Unless the laws of thermodynamics are completely wrong.

It's easier to squeeze something into an existing model as an "anomaly" than it is to rework our model to perfectly describe our universe. Baby steps

System of nature is vast for us, otherwise tiny. So life form may complete its era without noticing these changes. But life form is human perspective. Everything is alive or dead. If you want to notice these changes, you can do so as a star, planet, etc.

"Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space." ― Douglas Adams, _The Hitchhiker's Guide to the Galaxy_

Broaden your perspective. System of nature is vast for us, tiny otherwise. So that life form may complete its era without noticing any changes in cosmic system. But life form is human perspective. Everything is alive or say dead. If you want to notice these changes, you should be as huge as a star, planet, etc. For us, their movement is seemless, dead slow and even still. But this is not important. In ancient era, our philosophers & priests were true that the system of nature is Infinite (limitless) and Eternal (timeless). Anything you see or feel is the perceptive of biological life. You can't go beyond this perspective because you are locked into life and death is the key. Things beyond human perspective might be different. The name Universe limits your infinite (limitless) and eternal (timeless) perspective or the actual perspective. Time doesn't exist in the Infinity (of nothingness), as infinity is eternal (always there). Infinity is a logical fact, because something has to be there everlastingly, after everything else, even it is nothingness or vacuum. Mass resides inside vacuum. Mass needs vacuum to reside inside it or exist, but vacuum doesn't need mass for its existence. Vacuum or nothingness is the actual realm and constitutes infinity. The virtual mass is actually the displaced vacuum, which is like an adhesive bond that forms systems. This is how mass & vacuum are interrelated at the smallest virtual particle level. This relationship forms vacuum-mass bonded systems in this infinite and internal system of nature. Vacuum or nothingness is the actual realm and constitutes infinity. Things beyond human perspective might be different. The Creator or Deity may be something other than mass-vacuum infinity or something beyond mass-vacuum infinity. There is no scientific proof of this concept, but the Infinity is a logical fact, as there has to be something beyond everything else everlastingly, even it is vacuum or nothingness. If you want to travel into the infinity (of nothingness) to resolve it, before you start journey, you can imagine that this everlasting infinity is already laid out somehow out there everlastingly, which is a mind blowing logical fact, as there has to be something beyond everything else everlastingly, even it is vacuum or nothingness. In our infinite and enteral perspective, all intermediate entities are the various phases of mass-vacuum relationship, for instance rock, planet, star, universe, multiverse and so on in the system of nature...

Hundreds of millions of years. Not even joking

@@nikkibelair8899 In my opinion there is life everywhere, even sentient one. But, everything is so far away that as we look at stars and planets, we see their past and therefor we cannot see life activity.

Hey don’t worry. The photos you see are the result of multiple exposures, creating a composite image. The images are enhanced to create this beauty. They are far more beautiful in these photos than they are in reality. As for going to see one for yourself, they are so huge that if you every get a chance to go into interstellar space and visit one of these galaxies in person you would not be able to witness them as spiralling colourful entities. The gasses are invisible in our visual colour range and the stars of the galaxy are many light years apart from each other. So what you would see is just another starry night sky- much like we do from down here on earth. We are already at the edge of one of these beautiful galaxies the Milky Way! Step out side at night if you want the shortest trip to see a galaxy How it truly is. Beautiful enough I’m sure you’d agree

If I understand your question correctly. Just my opinion based on what I understand - Gravity. It's is not really spinning, it is more orbiting. Spinning is when an object rotates around its own axis. Orbiting is when one (usually smaller) object moves in an orbit around another (larger) body. Basically they orbit around each other. This is due to the gravitational forces between them which is generally initiated by moving towards each other, but not in a straight line. This orbital motion is what keeps celestial bodies from just plain crashing into each other, which also happens quite often, hence the craters on our moon, for instance. If the gravitational force between bodies are too weak, they might just pass each other. There are basically the three main events which could take place with celestial bodies in relatively close proximity of each other: 1. Just plain crash into each other. 2. Orbit each other. 3. Pass each other. I hope this helps and that your question was not merely rhetorical.
