There's a lot of ongoing research trying to answer that question, but right now our best model is that after the Big Bang, matter wasn't distributed evenly. The very slightly denser areas attracted other matter to them, and after a while most matter was clumped up into what later became young galaxies.
If we have a couple of other smaller galaxies colliding with our own is this the reason we have more then one black hole in our galaxy. Does anyone know how many black holes our galaxy has?
Well there's a difference between blackholes and super massive black holes that aren in the center of galaxies. The only difference really being size. The blackholes in the center of most "active" galaxies are massive. When galaxies collide the black hole will orbit eachother and the galaxies will sort of spin through each other. On each orbit they will get closer and closer till they collide and become even bigger and the galaxy get bigger and becomes one galaxy with 1 massive black hole.
i don't know, a black hole may exist then it will be back to normal again. it is as far as i know. And i haven't heard that a galaxy will collide with the other because galaxies are so far apart from the Milky way. Andromeda is Lightyears away from us. It may be impossible that a galaxy will move closer from ours. I'm only thirteen and that's what i think.:D
It's a competitive field, but if you love it, then there's a place for you in it. Best place to start is by taking astronomy and physics classes, and seeing where your interests lead you.
Surprisingly it probably wouldn't even be noticed. Reason is that it would happen so gradually that it would take many lifetimes for us "laypersons" to even notice. Only problem would be if a particular star were on course to collide with our particular star (the sun) which is highly improbable anyways. If collision were imminent then we would gradually realize that we were going to be "screwed" in the next million years or so. So; Don't worry, be happy!!
Actually, some of our Spitzer scientists recently discovered that we've been underestimating the size of the Milky Way for decades. We now know that the Milky Way is, in fact, a little bit larger than the Andromeda Galaxy. That's part of what I love about astronomy. We're always having to rewrite the textbooks. :)
Milky way is bigger??? Then that means that we have more than 200.000.000 stars (the number of stars in the Andromeda), and the diameter of the Milky way would be bigger then 100.000 light years (as we thought before)
By one of the U.K.'s scientists (i cant remember his name :D) there are 361 more civilizations in our galaxy counting with us there are 362 Civs. But so there are millions of stars and the distances are too big we can't reach each other.
by the latest calculation, there is a chance for developing a life like ours (being able to communicate trough universe) in this time only 2 in whole universe. That explains why all our searches in space came back empty. ;)
It can't really be calculated with any accuracy because even though we can estimate how many earth-like planets exist, we don't know the likelihood of life forming, nor do we know the likelihood of munticellular animals evolving, nor do we know the likelihood of intelligent life developing, nor do we know how long intelligent life exists before going extinct. However, to me those estimates seem too conservative. The universe is rich with organic molecules, and evolution is a powerful tool.
I new discovery from the Hubble shows that they found a life form planet in a solar system in our galaxy that is found in the same arm that our solar system is in. I watched a program on it on the discovery planet a few days ago.
love it.....peep my video ''to the stars'' its a journey from the earth to the universe.. im sure you'll enjoy the song i created for the video.... Ty Statz
We use artist concepts when we need to show the whole Milky Way Galaxy. Obviously, the only real pictures we can get of it are from the inside looking out.
Some interesting facts I looked up are: 1. Light takes 8 minutes to get to earth so what you see is the sun 8 minutes ago, it could've blown up for all we know! 2. We are 2.3 million light years away from Anromeda galaxy so it takes 2.3 million years for light to reach us, meaning were seeing andromeda galaxy as it was 2.3 million years ago!
It won't. On the documentry "Death of the Sun" they say it's not big enough to. only very big stars bigger then our sun explode. What will really happen is that it will expand a lot and edventurly shrink into a white dawrf.
For perspective. The Sun's light takes roughly 8 minutes to get to earth. Moonlight takes about 1.5 seconds. At the speed of light it would take 4 hrs to get to Neptunes orbit (current last planet in the solar system).
So a light year is 131,400 times the distance to the edge of the solar system (based on Neptunes orbit)
Well, that depends on your speed. Going 1 mile at 1 mile per per hour takes an hour, but going 60 miles per hour it takes a minute.
Doing some quick math, it looks like Voyager 2 would need about 15,000 years to go one light-year, and that's one of the fastest-moving spaceships we've got.
Why do people watch these videos and then comment as though they are the specialist on the universe. I though this was a cool video and actually had no idea about the colliding small galaxies. I'm going outside right now to see if I can spot Andromeda before our galaxies get married.
i think you do have a point. i love science, and i think it's extremely important. but there are some serious problems here on the surface of our planet. we have the resources, skill, money, compassion, drive to create an absolute paradise for every single person on earth. but we don't. because we're lead around by the nose by people who don't see the big picture. because no one taught them science. taught them how every human is connected to the entirety of existence.
oh, wow, I didn't konw Canis Majoris was so close! o.o mind bottleing... I'm so looking for it now lol, and the andromeda galaxy (which will eat the milky way in about 3 billion years... O.O)
the video says a dwarf galaxy is colliding with ours not Andromada. That is 3 billion years away from happening. Also I know it is not a dwarf galaxy.
To EraofAwakening your wrong. We currently believe that andromeda is on a merging course with us, that will happen in approx 2-3 billion years. We currently have 2 dwarf galaxies merging with our own galaxy the milkyway that is stated in this video
2 million light years away, holy cow!!...5.8 trillion miles is one light year! so, 5.8 trillion X 2 million to get your distance away in miles...WOW!!
Wait... if every galaxy is composed of a Blackhole in its center... Doesn't that means that the Canis Majoris dwarf galaxy has a blackhole the nearest blackhole to Earth?? or is there a definition for a dwarf galaxy I'm missing? Anyways this information about the dwarf galaxies that are colliding with ours was unknown to me. Thanks!
Well yeah but still there COULD be life on one of those and remember " We are not alone. To think that we are the only lifeforms in this galaxy is just ignorance. " Totally agree with that in all meaning.
No, the Milky Way is actually a barred spiral. The Canis Majoris dwarf galaxy doesn't have a defined shape any more -- it's been stretched out and twisted up too much by its interaction with the Milky Way.
at every thing you look it makes you wonder, human beings are made from a tinny sperm compare that to the size of the unverse, we forget this and yet we think we are at the centre of the universe but take your time you will find there is no God But Allah and Mohammed is his messanger read the quran the answers are there. the big bang is mentioned in the Quran 1400 years ago. miracle search for self the truth
logic is predictable, but strings theory, nano technologies aren't in your book. We also demonstrated that we are not the center of the universe in the multiverse. Some religions doesn't think that there is only one centered thing. But definitively we are not thinking we are the center of the universe, that's wrong.
Until the mid-20th century, the prevalent view across the world was that the universe was infinite, had existed forever and that it will continue to do so for all time. According to this view, known as the "static universe model," the universe had no end or beginning.
He (Allah) is the Originator of the heavens and the earth. (Qur'an, 6:101)
It's amazing (I knew it, and I think no one should deny this) but there are several new ideas about it. The universe could be not infinite because nothing is immortal (only Allah) So the galaxies can flyes at any speed, there atoms aren't eternal. One day it will just stop to grew. The fact that nothing is static doesn't mean things are infinite. So to me there's kind of contradiction.
Allah invites people to consider this truth in the following verse:
Are you stronger in structure or is heaven? He built it. He raised its vault high and made it level. He darkened its night and brought forth its morning light. After that He smoothed out the earth... (Surat an Naziat: 27-30)
Elsewhere it is declared in the Qur'an that a person should see and consider all the systems and balances in the universe that have been created for him by Allah and derive a lesson from his observations:
He has made night and day subservient to you, and the sun and moon and stars, all subject to His command. There is certainly Signs in that for people who pay heed. (Surat an-Nahl: 12)
We haven't found evidence for life anywhere but the Earth yet (though there's some hope for finding bacterial life on Mars). There are several programs that are looking, though!
Thanks man , this stuff is so interesting. And you dont have to answer this , but do YOU believe that there is a chance of a massive meteor hitting Earth anytime during the next 100 years or its just a silly made-up idea ?
That depends on what you consider "big." Something the size of a bus won't do much damage on a global scale, but wouldn't be much fun to have hit your house. Once a century is pretty average for that size rock. The odds go down as the size of the rock increases, but I think it's worthwhile to locate and characterize them even if the risk is low, because we don't want to be caught unaware the way the dinosaurs were...
they wrote that eventually everything will pull it all in. i've heard of this. will this mean that the whol universe will become a black hole or will everything just be gone?
There's actually a whole *field* of cosmology dedicated to trying to determine what the end of the Universe will look like. It probably won't be a giant black hole, though, because even black holes slowly evaporate.
in the beginning there was an infitely small point of matter surrounded by absolutely nothing forever. the thing exploded and evrything we call our universe came out of it matter and antimatter and gamma rays... this stuff was thrown out from the centre due to the explosion and is expanding out into emptyness ever since. even interstellar space contains some energy and matter, beyond the edge there is nothing thats all. gravity holds the universe together and eventually will pull it all back in!
if our galaxy is a spiral galaxy and our sun is out on one of the arms... the centre of the milky way seems to be a huge bulge much brighter and super massive compared to our sun... why cant we see it ??
The center of our galaxy is shrouded behind a cloud of dust. Google the Spitzer Space Telescope or the 2MASS project for good images through the dust.
wow thats so amazing i dont know if this has to do anything with astronamy but is time real or is it just something used by humans to understand stuff plz answer
According to the Special Theory of Relativity, time is a physical dimension just like length, width, and height. How it relates to what we perceive as "time passing" is the subject of a lot of ongoing research and debate...
The way we measure time is man-made. There's no universal time scale. It's are all relative to our position , gravity, and speed relative to other objects.
Time is a 'real' thing. If you could step out of the third dimension and look down on it from the fourth, you would look like a long snake with your embrionic self at one end, and your deceased self at the other. Like taking a photograph of something moving. It will smudge. Make the exposure long enough, thats seeing in 4D!
I am amazed that light from a galaxy 2 million light years away is still visable. Considering the emittion occurred 2 million years ago, I just cam't imagine that the light would still exist over this long period of time. If this is true, a super telescope from another galaxy can look towards earth and be looking at dinosaurs right now even though they are extinct?
That's right. If some alien civilization had a telescope that could resolve the surface of the earth, they'd see it as it looked in our past, not as it looks in our present.
Space is empty. Light can travel for billions of years, uninturrupted. Unless of course it hits some gas from a nebula or something, but remember light travels in a sphere, so even though it may not reach earth, it will still be seen from other points in the universe.
Space is not empty. There is space gas everywhere. And lights travel according to physical and gravitational laws. And if it doesn't reach you, you don't see it.
Absolutely incorrect. This is what we used to call 'ether'. Space does not have 'gas everywhere' as you describe. If it did, we would not be able to see the light from Galaxies that are millions (Let alone 28 Billion) light years away, because the light would be diffused by the gas. But keep on truckin'!
no i mean think about it pluto is no longer a planet becuase its dwarf planet so those galaxys of which u mentioned are too tiny its justl ike vidoe game before u fight thel ast boss u sometimes fight a mini-boss
I agree with what seabrain said. There is so much knowledge out there about the universe. For parents to not teach their kids or to not let them read about the universe rather than the holy texts is a great injustice to learning.
I wish children would be sitting in awe of this and learning about science, like I did, instead of sitting in a church being guilt-ridden and indoctrinated by ignorant religious lunatics.
so how do you think would large galaxies like the milky way created ? :)

SpitzerJim 3 years ago
First , you must know that all light travel at speed of 3 x 10^8m/s
Then use 3 x 10^8m/s X 60(minutes) X 60(hour) X 24(days) X 365(Year) = 9,460,800,000,000 KM = 1 light year
Light year is the calculation of distance and time taken for light to reach.

at every thing you look it makes you wonder, human beings are made from a tinny sperm compare that to the size of the unverse, we forget this and yet we think we are at the centre of the universe but take your time you will find there is no God But Allah and Mohammed is his messanger read the quran the answers are there. the big bang is mentioned in the Quran 1400 years ago. miracle search for self the truth

logic is predictable, but strings theory, nano technologies aren't in your book. We also demonstrated that we are not the center of the universe in the multiverse. Some religions doesn't think that there is only one centered thing. But definitively we are not thinking we are the center of the universe, that's wrong.

Part1
Until the mid-20th century, the prevalent view across the world was that the universe was infinite, had existed forever and that it will continue to do so for all time. According to this view, known as the "static universe model," the universe had no end or beginning.
He (Allah) is the Originator of the heavens and the earth. (Qur'an, 6:101)
wallidjan 3 years ago
(Part 1)
It's amazing (I knew it, and I think no one should deny this) but there are several new ideas about it. The universe could be not infinite because nothing is immortal (only Allah) So the galaxies can flyes at any speed, there atoms aren't eternal. One day it will just stop to grew. The fact that nothing is static doesn't mean things are infinite. So to me there's kind of contradiction.

Part2
Allah invites people to consider this truth in the following verse:
Are you stronger in structure or is heaven? He built it. He raised its vault high and made it level. He darkened its night and brought forth its morning light. After that He smoothed out the earth... (Surat an Naziat: 27-30)
wallidjan 3 years ago
Part3
Elsewhere it is declared in the Qur'an that a person should see and consider all the systems and balances in the universe that have been created for him by Allah and derive a lesson from his observations:
He has made night and day subservient to you, and the sun and moon and stars, all subject to His command. There is certainly Signs in that for people who pay heed. (Surat an-Nahl: 12)

We haven't found evidence for life anywhere but the Earth yet (though there's some hope for finding bacterial life on Mars). There are several programs that are looking, though!

What is that huge ball of light in the middle of spiral galaxies ?

That's the central core. Lots of stars very close together.

Also , Ive heard of white holes and worm holes , have scientists ever seen one before ?
MichaelSwg 3 years ago
Right now both are purely theoretical, but so were black holes when I was a kid.
SpitzerJim 3 years ago
Thanks man , this stuff is so interesting. And you dont have to answer this , but do YOU believe that there is a chance of a massive meteor hitting Earth anytime during the next 100 years or its just a silly made-up idea ?
MichaelSwg 3 years ago
That depends on what you consider "big." Something the size of a bus won't do much damage on a global scale, but wouldn't be much fun to have hit your house. Once a century is pretty average for that size rock. The odds go down as the size of the rock increases, but I think it's worthwhile to locate and characterize them even if the risk is low, because we don't want to be caught unaware the way the dinosaurs were...

Nibiru is mythical. Numerous surveys have failed to find any observational evidence to support its existence.

This has to do with what lucasleivia siad:
they wrote that eventually everything will pull it all in. i've heard of this. will this mean that the whol universe will become a black hole or will everything just be gone?
PenguinCharmi 3 years ago
There's actually a whole *field* of cosmology dedicated to trying to determine what the end of the Universe will look like. It probably won't be a giant black hole, though, because even black holes slowly evaporate.

can you answer my previous question about the "bulge"
jamfen 3 years ago
in the beginning there was an infitely small point of matter surrounded by absolutely nothing forever. the thing exploded and evrything we call our universe came out of it matter and antimatter and gamma rays... this stuff was thrown out from the centre due to the explosion and is expanding out into emptyness ever since. even interstellar space contains some energy and matter, beyond the edge there is nothing thats all. gravity holds the universe together and eventually will pull it all back in!
lucasleivia 3 years ago
if our galaxy is a spiral galaxy and our sun is out on one of the arms... the centre of the milky way seems to be a huge bulge much brighter and super massive compared to our sun... why cant we see it ??
jamfen 3 years ago
The center of our galaxy is shrouded behind a cloud of dust. Google the Spitzer Space Telescope or the 2MASS project for good images through the dust.
SpitzerJim 3 years ago
wow thats so amazing i dont know if this has to do anything with astronamy but is time real or is it just something used by humans to understand stuff plz answer

According to the Special Theory of Relativity, time is a physical dimension just like length, width, and height. How it relates to what we perceive as "time passing" is the subject of a lot of ongoing research and debate...
SpitzerJim 3 years ago
The way we measure time is man-made. There's no universal time scale. It's are all relative to our position , gravity, and speed relative to other objects.
Time is a 'real' thing. If you could step out of the third dimension and look down on it from the fourth, you would look like a long snake with your embrionic self at one end, and your deceased self at the other. Like taking a photograph of something moving. It will smudge. Make the exposure long enough, thats seeing in 4D!

I am amazed that light from a galaxy 2 million light years away is still visable. Considering the emittion occurred 2 million years ago, I just cam't imagine that the light would still exist over this long period of time. If this is true, a super telescope from another galaxy can look towards earth and be looking at dinosaurs right now even though they are extinct?
pcwhizmail 4 years ago 2
That's right. If some alien civilization had a telescope that could resolve the surface of the earth, they'd see it as it looked in our past, not as it looks in our present.

Space is empty. Light can travel for billions of years, uninturrupted. Unless of course it hits some gas from a nebula or something, but remember light travels in a sphere, so even though it may not reach earth, it will still be seen from other points in the universe.
jians5 3 years ago
Space is not empty. There is space gas everywhere. And lights travel according to physical and gravitational laws. And if it doesn't reach you, you don't see it.
Few ideas, and very confused :-)
markoer 3 years ago
Absolutely incorrect. This is what we used to call 'ether'. Space does not have 'gas everywhere' as you describe. If it did, we would not be able to see the light from Galaxies that are millions (Let alone 28 Billion) light years away, because the light would be diffused by the gas. But keep on truckin'!

In the nam of allah
[37] When the sky is rent asunder, and it becomes red like ointment:
[38] Then which of the favours of your Lord will ye deny?
[39] On that Day no question will be asked of man or Jinn as to his sin,
[40] Then which of the favours of your Lord will ye deny?
[41] (For) the sinners will be known by their Marks: and they will be seized by their forelocks and their feet.

I agree with what seabrain said. There is so much knowledge out there about the universe. For parents to not teach their kids or to not let them read about the universe rather than the holy texts is a great injustice to learning.
