If anyone is wondering why they re-uploaded check 5:05. The last video said the "center of our universe" Now it says the "center of our galaxy". Correcting those small errors. Good Job DNews!
WE FIXED IT!!! There was an error at 5:05 where our VO person misspoke, saying center of the UNIVERSE rather than GALAXY. It's all better now, and thanks for keeping a watchful eye on us, y'all!!
Center of the universe, center of the galaxy...toe-may-toe, toe-mah-toe, what's the big difference? ha ha. But seriously though, could you make a video on why the point in space where the little golf ball sized mass that contained all the condensed matter of the universe and supposedly exploded during the Big Bang, is not a place that we can point to and say that is the point in space where the golf ball sized mass exploded and where the Big Bang started from, and is the center of the universe that all the galaxies are moving away from in a general spherical fireball shape? I heard that that is not the case, and that there is no center to the universe, but I could never understand that and it always makes my mind explode.
@Joey I think the issue isn't so much the mirror's size as it would be getting the *surface* of the mirror to be perfectly level across the entire thing
+Bob actually there is a huge difference between the center of our galaxy and the center of the universe so... There are some good videos on other science channels, PBS scishow I think?, explaining (better than I ever could) why really everywhere is the point where the universe exploded into existence from a single point. But yeaaa glad to see you have an interest in science; keep thinking about it and one day you'll have a lightbulb go off
Hey DNews fans! We had to make a small correction to the video, so yes, this is a re-upload. But our crew went all the way to Chile just to bring you this video and we think it's awesome! So even if you watched it once, maybe show it some love and watch a second time...or a third...fourth... Thanks! :)
Wait what? What is this video at 5:05? I've seen it before that's why I'm asking... Is it a real video? Is it a simulation? Dnews do you have any info on that? Thanks!
Question: How do they know that the telescopes provide an error-free image of whatever they are looking at? I mean, how can they be sure that the information they get from object at massive distance from us is not incorrect because of a telescope failure (maybe when it was built, maybe mechanical failure, maybe software error...)
In the original video, she said "black hole in the center of our universe..." at 5:07. They reuploaded the video after correcting this minor mistake because of so many people pointing it out in the comment section.
The light beams in the VLT interferometer, or any other optical interferometer, are not combined "using a computer". Optical interferometers combine light using mirrors, beam splitters and a high precision mechanical apparatus. It is true that the apparatus is controlled by computers, but the light combining is accomplished using the optical and mechanical components. The story is different for radio telescopes. With radio interferometers, specialized digital computers are fast enough to simulate the interferometric process through computation. Radio telescopes do not need a physical interferometer.
after watching the chapter on discovery's webpage, i must say that the voice in this video is much much more intriguing and inmersive than Trace's voice.
What we should build is a space telescope with a Mylar mirror over a mile in diameter. The mirror could be supported by a simple wire frame, or memory metal.
0:38 You can clearly see saguaro cactuses, which are only native the south western U.S. Did they use pictures taken in the states or does Chile have them as an invasive species?
If they could image the event horizon they should also be able to resolve the accretion disc around the black hole, that would probably be more useful than the event horizon as they could observe material actually being dragged into the black hole, which would tell us lots about the way its gravity distorts stuff.
sagittarius a doesnt have a disc around it. it was estimated that only about 1 solar mass of matter is "eaten" by the black hole per year. astronomers have been observing it for a while now and found out that there isnt really much going on at the center of our galaxy.
I wonder: could they try and image the black hole against the Cosmic Microwave Background? Because the CMB is present in all directions, wouldn't the black hole appear as an actual black spot on the CMB? Maybe the CMB frequencies do not allow for sufficiently detailed imaging?
+Brandon Toft hence why I put "AT THE VERY LEAST" in all caps in the hopes that no one would feel the need to tell me that about something everyone already knows... :)
Christian Rankin Yes but you said with a probe. Probes have mass. Therefore it would not be "AT THE VERY LEAST" because that would not be possible no matter how technologically advanced we become.
Brandon Toft you knew what I meant and you knew that I am aware of all those things, but by all means, continue explaining as if this is my first episode of D-News :)
I've already seen footage of this in a way. While not actually "seeing" the black hole, they showed you all these suns flying around this invisible mark in the centre of the picture, they were even excited about a gas cloud they saw was going to get sucked in and hoped to see expulsions, so what's this video all about?
I would argue that LIGO directly observed the collision of two black holes, and thus directly observed black-holes unlike what the video said near the beginning. I will admit that we have never seen one using light but then again it is a BLACK hole.
I like this video format and I hope they will go this way with all their videos rather than having that "punch me in the face" Trace all over the screen :)
If anyone wants to imitate a German accent listen to this guy. That's like the most neutral german accent there is, not those over the top ones I hear on American Tv. Very interesting video, too!
a small comment although a great video the discovery of the gravitational waves few months ago was from a binary black hole system so this means that apart from the gravitation waves we detected directly black holes!!
"Just like all blackholes, astronomers have yet to view one directly to confirm its existense".. My question is, if we can view into the far reaches of universe and take amazing photos of galaxies and other formations... Why cant we view a black hole that is in our own galaxy? What evidence shows that they actually exist?
I realize the sentimental significance of viewing the black hole at the center of our galaxy, however wouldn't it be easier to try and view the black hole at the center of other galaxies? That way we don't have to try and look through the billions of stars that are between us and the center of the Milky Way, and instead look through empty space at a galaxy whose plane of rotation is perpendicular to us? I would suggest andromeda but i have no clue of its orientation relative to us.
no other supermassive black hole is as close as sagitarius a. its only about 30k-50k lightyears away. andromedas black hole is already 4million lightyears away and thats the next closest.
Saying we have not detected a black hole before is incredibly misleading. We know from the orbit of objects around black holes that something emitting no light and with incredible mass must exist there. We have also detected waves propagating out from the black holes. If you don't count gravitational waves, fine, but in that case why would you settle for light emitted from the outside of the event horizon? Nothing against this observatory or what they are trying to accomplish, we can still learn a lot about black holes. I just don't like when people try to hype new by discrediting the old.
I don't understand this? Haven't they all ready confirmed the existence of black holes by looking at its effects on nearby stars. I understand seeing one for the first time with the naked eye is cool but to actually confirm that it exist one must see visually?
The gravitational effects on neighboring objects to the black hole have ben observed, but neither the event horizon itself nor the closer regions to it.
Reupload because they made a mistake, the woman in the original said "the black hole in the center of out universe" where as obviously it is in the center of out galaxy, now they uploaded it with the correct voice-over.
Just imagine what would happen if it looked a lot like Gargantua from Interstellar... The movie would get all the Oscars and awards despite that chance having passed xD
then next time we should make orbital telescopes around the sun and that means the resolution is crazy then after faster than light is possible we should analyze all new data with interferometry like from sun and proxima century
"a golf ball 9 miles away". Relative to humans and their ears, sure. But relative to the size of the universe? Might as well take them down and go feed some kids.
What is included in them. Possibilities include an alternate universe when you travel inside a black hole, transporting to the other side of our universe from a black hole, or even shirking until your are nothing inside a black hole. We will never know until we explore them.
If anyone is wondering why they re-uploaded check 5:05.
The last video said the "center of our universe" Now it says the "center of our galaxy".
Correcting those small errors. Good Job DNews!
Thanks @Lgm15D - there's no way we could live with ourselves if we didn't correct it!
+Aneeta Akhurst Lol!
+Aneeta Akhurst 😂
"small" error. Good job DNews :)
Sounds like some writer for the channel has been thinking about no man's sky lately :)
I really like this bite-sized documentary format! Way to go, DNews!
Thanks +Sean Lumly we're hoping to do a few more of these in the future, so stay tuned!
***** You can count on it! :)
I really like the documentary style and the production value. More of this please!

I heard that that is not the case, and that there is no center to the universe, but I could never understand that and it always makes my mind explode.
Hey Trace can you explain why it would be impossible to build a 100m mirror?
@Joey I think the issue isn't so much the mirror's size as it would be getting the *surface* of the mirror to be perfectly level across the entire thing
Thanks for acknowledging the error and then going to the trouble of fixing it.
+Bob actually there is a huge difference between the center of our galaxy and the center of the universe so...

Her voice is perfect for this kind of video. The video quality was amazing. Good job!
I think this is my favorite DNews video. More in this style please.
Yes! I really enjoyed this!
+Arthur78 Thanks!! We're hoping to bring a few more web doc style eps your way in the near future...so stay tuned.
Wow, this was a lot like what discovery used to be like. Nice.
Excellent, excellent video.. Expertly produced.. Love it... More like this please...
Damn solid video. It's TV quality
Thanks +MultiSaffran, glad you liked it!
My dosis of curiosity for astronomy has been satisfied for the day. Thank you Dnews.
Now this was a great video ! Keep up the good work guys
The reupload seems to be because in the original video they accidentaly said, at one point, "center of our universe" instead of galaxy.
this video really made me realize why I love science so much. top notch production quality, Seeker!
Hey DNews fans! We had to make a small correction to the video, so yes, this is a re-upload. But our crew went all the way to Chile just to bring you this video and we think it's awesome!

🇨🇱
The repload is because they changed "centre of our universe" to "centre of our galaxy" at 5:07
This new format is awesome!!
Such a soothing voice... Perfect to talk about the universe.
Great work guys and keep this level of content coming. I will watch and like ALL of them :)
Around 2:29 if you look in the center of the picture you can see some distortion in the middle. It COULD be the black hole we are looking for.
Wait what? What is this video at 5:05? I've seen it before that's why I'm asking...
Is it a real video? Is it a simulation? Dnews do you have any info on that?

This was a wonderful documentary-like video.
Wow, like this format way wayyyyy better that the "The Soup" format of the guy talking in front of the camera. More of these please.
The advent of flight and later space exploration has driven the very essence of technology for the past 100 years.
how reflective is ice? Would it be possible to shape massive ice burgs in the north or south poles to act as mirrors for even more massive telescopes?
What we should build is a space telescope with a Mylar mirror over a mile in diameter. The mirror could be supported by a simple wire frame, or memory metal.
I love the new format! Almost Discovery tv quality!
Her voice is so soothing!
with this telescope setup, do you need to calculate the earth curvitair?
High quality video! Loving it!
yet they are using dell computers from the 2000's
Levitin M. Those are monitors, the PC is what actually generates power

Says this isn't a race to see who can find out more about black holes. Names video "The Race to find out more about black holes"
the featured astronomer is really handsome!
Were those saguaros at 0:36, or just a remarkably similar cactus that grows outside of the Sonora Desert?
It's 2018 now, any news?
I wonder: could they try and image the black hole against the Cosmic Microwave Background?
Because the CMB is present in all directions, wouldn't the black hole appear as an actual black spot on the CMB?
Maybe the CMB frequencies do not allow for sufficiently detailed imaging?
Damn, it's crazy to think that it would take 30,000 years , AT THE VERY LEAST, to reach that thing with a probe, assuming everything goes well lol
It would take longer than that since anything that has mass cannot travel at the speed of light. You are looking at many times that amount of time.
+Brandon Toft hence why I put "AT THE VERY LEAST" in all caps in the hopes that no one would feel the need to tell me that about something everyone already knows...
:)
Christian Rankin
Yes but you said with a probe. Probes have mass. Therefore it would not be "AT THE VERY LEAST" because that would not be possible no matter how technologically advanced we become.
true. mass=no ftl travel
Brandon Toft you knew what I meant and you knew that I am aware of all those things, but by all means, continue explaining as if this is my first episode of D-News :)

No mention of the James Webb Telescope? Much looking forward to seeing what it reveals about our universe. #JWST2018
I would argue that LIGO directly observed the collision of two black holes, and thus directly observed black-holes unlike what the video said near the beginning. I will admit that we have never seen one using light but then again it is a BLACK hole.
Am I the only one who still thinks of BFBC2 every time the Atacama desert is mentioned?
that was outstanding! Thanks!
This is trippy. I was just researching Sagittarius A two days ago...
It's good to see humans put their differences aside to come together to do something for the greater
why is it impossible to build a 100m mirror? please elaborate cause that seems like somethig we can accomplish
This is some TV-quality stuff right here. Take my likes!
I really loved this episode.
I like this video format and I hope they will go this way with all their videos rather than having that "punch me in the face" Trace all over the screen :)
If anyone wants to imitate a German accent listen to this guy. That's like the most neutral german accent there is, not those over the top ones I hear on American Tv.

maybe its because hes german but i could be wrong.

does anyone know when they expect to see the first pic of the black hole?
3:40/3:44 so obvious that the night sky is revolving around us not the over way around
Finally an innovative video~
The kind of super expensive projects I'm actually happy to back with my taxpayer money, haha.
You go guys!! We wanna see that thing!!
I realize the sentimental significance of viewing the black hole at the center of our galaxy, however wouldn't it be easier to try and view the black hole at the center of other galaxies?

Don't come there, The Grox is rulling there lol
(You'll only understand if you played Spore)
I'm afraid of finding out that we only have a few weeks before the black hole just eats our shit up after learning about it.
Damn, they're starting to get very creative with telescope names
i love how they call it the "VERY LARGE telescope....just great
I don't understand this? Haven't they all ready confirmed the existence of black holes by looking at its effects on nearby stars. I understand seeing one for the first time with the naked eye is cool but to actually confirm that it exist one must see visually?

It'd be cool if we could send radio telescopes into space and place them really far away to make a massive telescope.

out galaxy, now they uploaded it with the correct voice-over.

stop what?

check out Greg Jay Electric Universe
Astrophysics is funnnnnN!
4 MILLION times the mass of our fucking sun? God dam
space is really creepy when you think
about it...
Fascinating.
This may be a dumb question but why don't they use the Hubble?
hubble isnt doesnt have the right equipment to do that.
Some black holes are cannabinoid receptors. If you ever send a probe don't forget the weed.
then next time we should make orbital telescopes around the sun and that means the resolution is crazy then after faster than light is possible we should analyze all new data with interferometry like from sun and proxima century
"a golf ball 9 miles away".
Relative to humans and their ears, sure. But relative to the size of the universe?
Might as well take them down and go feed some kids.
great video. more reasons to subscribe to DNews for once!
can someone tell me 3:35 is that a daily night view there?
Why the reupload?
they mis said something
Oh it exists. GR has been confirmed too many times to be pretty sure of that.
why'd you reupload
got taken down?
why??
Re-uploaded to fix a mistake in the video (in case you didn't figure it out)
Star Dreamers oh ok
Wouldn't it be cool if after the superscope boots up and peers into the event horizion the event center shows an eye looking back at us....ohhh
We know more about space than our own damn ocean. 90% of the ocean remains unexplored.
is this a reupload?
yes
Why?
+Matthew Medina idk
I love her voice
5:12 "This isn't about who can do this first" Title say "The RACE To See The Black Hole At The Center Of Our Galaxy"
Maybe they should race to see who can make up better names for their telescopes. Very Large Telescope Array, just fuck my shit up.
I'm sure they could build a 100m mirror. You just have to section it off like the James Webb mirror
Is it DNews or Seeker Daily?
Why is it impossible to make a mirror more than 100m wide?
What if the black hole at the center of our galaxy went poof would we still rotate around it for 30,000 years
Cumbustion LOL your profile pic
What do we gain from learning about black wholes ?
What is included in them. Possibilities include an alternate universe when you travel inside a black hole, transporting to the other side of our universe from a black hole, or even shirking until your are nothing inside a black hole. We will never know until we explore them.
We're only alive for a short time. Isn't it worth usng the time we have to learn about the Universe we live in?
+George I agree ,along with getting to heaven
Let's put more connected telescopes on Mars and the Moon!
i want a BLT!
this is how real life No Man's Sky starts
