If the Sun is moving around the center of milky way, then we must know accident spots along it's way based upon time last known accident happened. I belive the path the Sun traces is not at all safe and In addition to it Sun has no brakes.
But if we passed throughout 4 spiral arms, does that mean we might of been exposed to other life bearing comets from those regions. Hence allowing for the possibility of many alien lifeforms to have come into contact with earth and added to our already rich flora and fauna. For instance how bizarre is the sea horse. It is one of the very few species where the male gives birth to its young. Is is plausible to think we may be a mix of several exo ecologies all existing on the one planet?
Free energy has been here for a while ,But a few ppl make too many billions from our energy needs to let this technology be known,Find the real deal, a free energy device at LT-MAGNET-MOTORdotCOM ,Let the revolution begin!
@breeannaqktjbl I have experimented in free energy (electronics tech) It's real the manetic motor is real and we live in a corporate matrix fraud. Just imagine with that free energy we could grow food 24hrs a day indoors with grow lights, that'd cut my food bill and of course I would share.. etc etc good would become the norm in this world. WE LIVE IN A CORPORATE MATRIX FRAUD
@SiriusMined Wait, what do u mean by the magnetic motor has nothing to do with free energy? Let me fill you in on something / I'm one of those people who actually tested this device many many years ago. We do not need to pay for electricity at the rate we pay for it .. Energy, we never needed to since the 1970's at least there. What are you talking about?
We cannot chart Milky way Galaxy visually using electromagnetic waves. It is close to impossible to chart visually and accurately.
Just look up the Milky way you will see the closes star at 4 light years and the star next to it might be 10,000 light years away. Keep in mind that every solar system in the galaxy is in motion around its center. That start may not be anywhere next to the first star now since we are looking at it as it was 10,000 years ago.
@Ripley747 possible. Do you have a better name to describe the process of a star's "life cycle"? Is there an "official" one? and what's wrong with that one?
@Seefood73 My vote is for "life cycles of stars." What's wrong with "stellar evolution?" Every uneducated, idiotic creationist out there is going to use the phrase stellar evolution to try to expand biological evolution to cosmology. In other words, they will use things like this to say, "Evolution doesn't explain how nothing became the universe." If it isn't biological evolution, then it isn't evolution since stars don't reproduce.
@Ripley747 Lemme guess - you're an American, right? :-) You guys invest so much emotion in wording and naming it's absolutely amazing. even Skeptics in the US can sit around for hours arguing how not to name things lest they evoke this association or that one. No wonder you guys invented PC speech, formerly known as newspeak :-)
ok, ok, sorry. I know what you mean, and I promise never to tell an American that the sun evolves from a yellow dwarf into a red giant. It matures into one.
@Ripley747 it's not, but the sensitivity to "the wrong word in the wrong context" is several notches higher than anywhere else I'm afraid. Like I mentioned, things like Political correctness, the "seven dirty words", these are all speech freedom stifling inventions that started in the US culture and nowhere else.

We see more red shift with distance, so this would mean after 14 billion years, the universe is expanding at a faster rate: Or the red shift is deu to interaction by the antimatter held beyond teh heliopase by a radiant star. Then we get X-ray star, as antimatter and matter aniahlate
This comment has received too many negative votesshow
The red shift is proportional t othe distance an object isd from us, so it is not logicla to blame it on universal expansion! That is lazy thinknig. Antimatter is drivenback from the heliopause so we know it interac ts with light - adn spoa red shift is what we would expect from antimatter. Think about it!
THe galaxy is ever expanding. Wonder what the purpose in that is. Wonder how that will end. Wonder what the stuff is that "non-expanded galaxy" since the galaxy has to expend in something.... so many secrets and yet arrogant scientists behave to know evrything..
@MasterofPainfulDeath Arrogant scientists? If you ever encounter a scientist that claims to know everything, I owe you 100 bucks. Because you won't. Science too is ever expanding. There will never come a point at which we know everything, that's our limitation. Like you say, what's the galaxy part of? How many more small particles do we have to discover to find the smallest? All is endless, at least that what I believe. Scientists just push the edge as far as we can.
I know enough to know that I'll never know it all... That's what I heard some drunk guy say once, and I will never forget it. I think that's the definitive proof that we'll never be able to disprove God, which is why agnosticism makes more sense to me now than than atheism ever did.
@captainquirk24 True. I don't know wether fairies exist or not, but it doesn't bother me not to believe in them. a lot of people hope for a god because they are afraid for their ego
A lot of people believe in god because they are afraid for their ego???? Well I don't and I know that's a total lie. You made that up yourself! How old are you?? NO, how informed are you??? LOL, show me some evidence of this claim if you want me to ever take you serious hahaha.
@captainquirk24 Atheism and agnosticism are not mutually exclusive positions. One deals with belief, the other with knowledge. You can simultaneously not know something, and not believe it. Do you believe in Big Foot? Do you know that Big Foot is not real? These are 2 very different questions.
Do you know there's no god? No? - You're agnostic.
Do you believe there is a god? No? - You're an atheist too!
Actually, I heard on a history channel special that the universe WILL stop expanding someday, and shrink and eventually kill us all. :) Or at least it was similar to that.
@captainquirk24 Actually since the discovery of Dark Energy it appear the universe may expand indefinitely into a 'Heat Death' scenario, but we need to understand what Dark Energy is before we can say for sure.
@TheFifthApes Yes, heat death... It becomes cold. The fuel burns out, a great expansion or ripping of atoms and cold. Just photons bouncing around for another almost seemingly infinite amount of time and then eventually, that burns out as well. That's one theory.
@JonThm - If you truly believe that this is the case and can provide evidence for it, then you should not waste another minute on YouTube and run to the nearest astronomy lab to present your findings....... or, you're a troll.
@JonThm While it's true that redshift is proportional to the distance travelled, it does not support your interstellar antimatter idea, so no QED. Antimatter would not cause an increase in wavelength just by being there. Argument fail.
500 million years how big is our galaxy and wow is our system relly traveling that fast thourgh it's orbit around the milky way galaxy i suprize we have not crash with outher stars so much gravty going so fast arounf eachother.hmm if one were to have a space ship and travel the oppisite away form our system they be screw and might never find hter way home :( space travel will be hard
The Milky Way is about 100,000 light years diameter. We are about 25,000 ly out from the center, and go around in about 250,000,000 years. That comes to a speed .0006283 ly per year (1592 years per ly), or 39.74 AU/year (about the average distance from Sun to Pluto).
It's not really that fast, and most nearby stars are moving at similar speeds, and there is vast space between stars. That's why we don't collide.
@Krumbz2003 Only 1% of the viewers. And I have to say that I agree with you: a thumb down is not understandable for such a nicely done educational video. If I would, I would give 4 thumbs up :-)
Wait, so why is our sun traveling faster than other stars that it can pass through multiple arms in the galaxy and overtake other stars? I thought that the discovery that all stars travel around the galaxy at relatively the same speed is what triggered the investigation into looking for dark matter.
I was always under the impression that stars rotated with the arms of a galaxy and not through them.... You would assume the dense arm would trap a small-average star like ours.
The arms of a spiral galaxy are 'pressure waves' moving through the stars around the galactic core. So yes, the stars do travel through them.
To my knowlege it's all about the relative velocities of the waves and the stars, so I don't think stars get 'trapped' - though for a brighter, shorter-lived star it could take longer than its entire lifespan to cross an arm!
@SireStefan Yeah but you have to take into consideration the relative emptiness of our galaxy. Are galaxy is probably some where on the order of being 98% empty space and only made up of 2% actual, concrete objects (kind of like an atom).
@TheSpankymonkey oh dude man, sorry. Butthead asked beavis if you could spank a seamonkey while they were watching a video. wasn't callin ya a butthead
That was one of the most informative and facinating casts I have seen in a while. I LOVED IT! Something about mapping out astronomical bodies and tracing back stellar history is just so cool. It's amazing to know that some cold climate periods in Earth's history correlate with moments when the Sun past through the Milky Way's nebular arms! That's astonishing!
@mycatisamoron You just answered your own question, gravity. All mass has gravity including the Sun and other stars. There is a higher density of stars in the center of the Milky Way galaxy which exerts a higher gravitational pull on the stars around it. Just like how the more massive Sun pulls the less massive Earth and other planets around it, the stars end up orbiting the center of the very massive Milky Way galaxy (which also has a super massive black hole inside.
@mycatisamoron: From outside the galaxy it is all the stars in the Milky Way; however, their mass cannot be high enough, and so there is a bunch more "dark mass" thrown in to make it work the way it is observed. As you get closer to the center (closer than we are), the massive black hole becomes dominant.
@sillygames Stellar evolution is wrong! It makes you kill people! You retarted atheist scientists are the spawn of satan. Believe in God, and worship him, instead of this vast universe that... wait, what? Hey, what am I doing here? 0_0
@Koujinkamu I was sort of joking... if someone had come along actually saying those things I probably wouldn't have replied... lol... I'm in the middle of a pointless PM exchange with a die hard "NWO" guy... I just gave him the biznus end of my less rational side.
@teemuruskeepaa Have you seen the Hipparcos dataset with the error bars added? It's ridiculous - half of the stars are like +/- 75% accuracy. IIRC there's going to be some new mission at some point to do a more comprehensive mapping I guess.
@puncheex More distant stars can be measured if they happen to be variable stars by looking at their apparent magnitude. Very distant things like galaxies you can infer distance from red-shift. Parallax only works for stars near enough that the position difference can be resolved. The Gaia mission as I mentioned should get more accurate data on more stars.
@Ormaaj: You are correct, but if you are wondering about that +/- 75%, the inaccuracies in judging distance is the culprit. Cepheid variables are useful for deriving intergalactic distances and those of clusters, but don't help a whole lot inside the galaxy. We don't have an accurate distance for Betelgeuse within a 40% band, even when its only about 700 light years away.

a lot of science in one video! i think i have to see this again. Thanks for posting/ making these great videos!

That was one of the most informative and facinating casts I have seen in a while. I LOVED IT! Something about mapping out astronomical bodies and tracing back stellar history is just so cool. It's amazing to know that some cold climate periods in Earth's history correlate with moments when the Sun past through the Milky Way's nebular arms! That's astonishing!

I don't get it. What is pulling gravity toward the centre of the milky way, to cause the sun to orbit it?

@mycatisamoron supermassive black hole
Rajkozuluf 1 year ago
@mycatisamoron You just answered your own question, gravity. All mass has gravity including the Sun and other stars. There is a higher density of stars in the center of the Milky Way galaxy which exerts a higher gravitational pull on the stars around it. Just like how the more massive Sun pulls the less massive Earth and other planets around it, the stars end up orbiting the center of the very massive Milky Way galaxy (which also has a super massive black hole inside.
DamienZshadow 1 year ago
@mycatisamoron: From outside the galaxy it is all the stars in the Milky Way; however, their mass cannot be high enough, and so there is a bunch more "dark mass" thrown in to make it work the way it is observed. As you get closer to the center (closer than we are), the massive black hole becomes dominant.

@Koujinkamu I was sort of joking... if someone had come along actually saying those things I probably wouldn't have replied... lol... I'm in the middle of a pointless PM exchange with a die hard "NWO" guy... I just gave him the biznus end of my less rational side.

Celestia is a great popularized set of the 3d-mapping archive. Other planetariums don't come even close to its usefulness.

@teemuruskeepaa Have you seen the Hipparcos dataset with the error bars added? It's ridiculous - half of the stars are like +/- 75% accuracy. IIRC there's going to be some new mission at some point to do a more comprehensive mapping I guess.

@Ormaaj: Well, if you have some super-accurate approach to finding star distances, I'm sure the world would beat a path to your doorstep.
puncheex 1 year ago
@puncheex More distant stars can be measured if they happen to be variable stars by looking at their apparent magnitude. Very distant things like galaxies you can infer distance from red-shift. Parallax only works for stars near enough that the position difference can be resolved. The Gaia mission as I mentioned should get more accurate data on more stars.
Ormaaj 1 year ago
@Ormaaj: You are correct, but if you are wondering about that +/- 75%, the inaccuracies in judging distance is the culprit. Cepheid variables are useful for deriving intergalactic distances and those of clusters, but don't help a whole lot inside the galaxy. We don't have an accurate distance for Betelgeuse within a 40% band, even when its only about 700 light years away.
