[@internetwanderer9053]

@Marco Creen Oh wow, where do I start... 1) "Go whine somewhere else" wow what a stupendous, intellectual response. By the way *you* are the one who started "whining" when someone posted a quote from NGT. So, there. 2) "Neil deGrasse Tyson is an american *astrophisicist* [...] and the *author of many science related books* " (source: Wikipedia) My quote dismantled your claims. An actor wouldn't study astrophysics at a university and certainly wouldn't be a director of Hayden Planeterium. Moreover, someone who "isn't a scientist" couldn't have written so many books related to astrophysics and be able to pass on this knowledge in such a simple language (see "Astrophysics for people in a hurry", which I have read by the way). Finishing, I am surprised that you called NGT and Bill Nye "charlatans" and said that they had sold their souls. Putting away how ridiculous this is, I'm sure you are able to elaborate this matter with logical argumentation. :)

There are so many places we don't know, there are animals and insects we don't know about and you know there are also tribes of people living on the earth we haven't even met and don't know of and we have explored only like 5% of the oceans and don't even know how deep it really can be because we have explored only so little of it. Even if we know where all the countries are, we still don't know all the nature in every place on the earth. There are plenty of places that are hard to get to and have not been explored for that reason. Even if we like to think we know almost everything, that's not true at all. But if you want to just conquer new continents then that you unfortunately can't do anymore.

[@NostalgicMem0ries]

@@annbellgrau Yeah im aware of that fact about only 5% explored ocean, but tbh apart some similar species that we dont know, mostly its same water all over. I dont see exploring some slightly different animal species more important or exciting than exploring planets, solar systems or entire galaxies... one planet might have more stuff that whole earth combined, for me that is true exploration, that might be compared to age of exploration in 12th-15th centuries when entire countries and continents were explored. And by exploring i mean beying first to find it, even be named by your name or smth like that. Maybe you meant personal exploration around world and knowing world by yourself, then yes its exploration too, but different from what i envision in my dream. For example movies like star wars, star trek, alien and others inspire me to think about massive exploration, harvesting some rare minerals from unknown planets, that only you know about, selling, trading it, travelling across cosmos etc. I was born way too early for that for sure :)

remember if you are looking at a star in the night sky that is 100 million lights years away, you are looking into the past as the star was 100 years ago,the star might not actually be there any more. light from the sun takes about 9 minutes to reach the Earth, so if our sun exploded, you wouldn't see the explosion for 9 minutes

[@Effect-Without-Cause]

Fun fact; you can see about 1500 light years away with the naked eye in a non light polluted night sky, and you can only see "big" stars. About 90% of all stars are red dwarves and you can't see those with the naked eye. Also; red dwarf lifespan is about 10 trillion years, and considering that the universe is about 14 billion years old; not a single red dwarf has "died" yet.

If you are correcting the "Andromeda is on a collision course with the Milky Way in 2 billion years part," those aren't directly related. Andromeda and the Milky Way aren't going towards each other at the speed of light. And they're actually not going to collide for 4 billion years.

[@rishithapremachandra9911]

Finding the size of the observable universe is basically done by knowing the age of the universe. Then you know how long that light have been traveling for from that point to reach earth. Then using that you can get the distance of the observable universe. If only it was so easy. This distance is also not correct because the universe is also expanding. That is the edge of the observable universe is moving away from us at a certain rate. This rate is found out by looking at the colour of the light wave, to put in simple terms. This "colour" is called the red shift. Basically think about a light spectrum. We can find the rate of expanding of space by looking at the red shift of light. (There's more to it but yea...) After considering the rate of expanding of space along with the age of the universe we find the size of the observable universe. (With math.) The reason we can't see the rest of the universe, is because the other light rays haven't reached us yet. Therefore it's the unobservable universe.

[@barbe00brune]

at some point its indeed impossible to "see" whats outside there. Astrophysicist are using tools that allowed them to measure things. By observing those measurement they can know whats happenning. Stars are the easiest to see since they produce so much light. So they could calculate the possible gravity attraction that star has. If that gravity shift at some point they would know something is there and depending on how strong the shift in gravity was they can know approximatly how big that unknown objet is (ex: a planet). Its more complicated than that but that can give you a good idea of how we know of the observable usiverse.

Short version. You measure the distance to each galaxy by the degree of red shift of elemental signatures known as Fraunhofer lines in the visible light spectrum coming from each of the galaxies. You then take into consideration the direction and you map everything. Nuts is if you do this to enough galaxies you end up with an overall map.

We cant actually see other planets or galaxy's unless they pass in front of another light source and them with high tech light detection we can detect planets and other galaxies but even then with the distance separating us from everything else maybe the planets we detect are already dead or destroyed. Same for the other stars we see.

Think of it like this. Imagine points in space moving apart by 1 meter per second (m/s) the first points are 1 m/s, the next points are 2 m/s, the next by 3 m/s, etc. so, points that are 300 million points apart are moving away from each other by 300,000,000 meters per second. This is faster than the speed of light, so light from those points will never reach you.

[@ehhidontknow]

“Observable universe” means that this is what we are capable of EQUATING with our current knowledge of astrophysics. Distances, masses, the elements surrounding a galaxy/planet/cluster are all in mathematical form. They’re equations that determine whether hydrogen, gas, etc exist within that area. We can’t quite literally see (in HD) farther galaxies but we are able to calculate it to determine what it is comprised off. Einstein’s e=mc^2 made this all possible for modern physics

Mazza what?

[@timelinescandals]

To answer: we can't properly "see" the observable universe, but we can measure light and sound and forces that emanate from those places. So even we can't see that there's a planet, a star or a galaxy there we are still able to guess (mostly by the size / amount of interference / light emitted / time it took to get here) what is it, how far away is it and how big is it.

[@7quantumphysics]

Trying to find galaxies with high powered telescopes (like the Hubble) is like looking for a light bulb among millions of other lightbulbs. Doing the same thing for planets is like trying to look for a dim speck of dust, hoping that enough light reflects off the surface for you to visibly see it. Finding galaxy clusters and finding planets require different techniques.

[@jarsky]

We don't observe exo-planets with visible light telescopes. We use a technique to monitor the stars, and measure the dip of light when the planet passes in front of the star which tells us its mass. Then by the spectrum of the light we get back, they can observe what the planet is made of which is how they work out if its an earth-like planet, or a gas giant, etc... The furthest we've ever observed visibly is about 15 billion light years. Most stuff extremely far away we use giant sensor arrays to do parallax measurements and then for even further away we do main sequence analysis with a lot of tricky math. We dont visually observe them.

[@cloverhal2284]

By using parallax (if the apparent movement of an object relative to you is faster than another object the second one is the farthest / or is going away from you or closing in. Objects going away are emitting more red light toward us that’s how we decipher the data) and interferometry which are methods allowing us to mesure the distance and the size of objects such as stars and galaxies we mapped what is currently around us. The Gaia European space telescope mapped several hundreds of millions of stars in our galaxy. Plus the universe’s structures (galaxies/clusters) are so gigantic that even at dozens of millions of light years away we can still observe them.

6:44 "Maffei 1 and 2 were discovered by Paolo Maffei in the 1960s, using infrared light. The optical light in these galaxies is heavily obscured by gas and dust. They belong to galaxy groups within our larger Local Supercluster." That's how i guess.

[@sonnieandjacob]

[@thephaneron3676]

You're right, these are simply extrapolations of the current data we can observe and quantify. Take the *Hubble Deep Field* image for example: _"The Hubble Deep Field (HDF) is an image of a small region in the constellation Ursa Major, constructed from a series of observations by the Hubble Space Telescope. It covers an area about 2.6 arcminutes on a side, about one 24-millionth of the whole sky, which is equivalent in angular size to a tennis ball at a distance of 100 metres. The image was assembled from 342 separate exposures taken with the Space Telescope's Wide Field and Planetary Camera 2 over ten consecutive days between December 18 and 28, 1995."_ _"The field is so small that only a few foreground stars in the Milky Way lie within it; thus, almost all of the 3,000 objects in the image are galaxies, some of which are among the youngest and most distant known. By revealing such large numbers of very young galaxies, the HDF has become a landmark image in the study of the early universe."_ If 3,000 countable Galaxies exist within a single photograph spanning 2.4 arc minutes, how many more could be extrapolated on average for the entire sky? It's just an estimation. To put the size of this image and the amount of Galaxies crammed into it into perspective, *the sun is 32 arc minutes in angular diameter (0.53°) and is this 13 times larger than the Hubble Deep Field!* Hope this helps guys 👍

[@DaimonAnimations]

What they mean that we can currently see is not just with telescopes but also radiation measurements, mathematics, physics and quantum measurements and a lot of science and tech that has been built to measure distance and to study out the universe. It takes so many brilliant minds every day from NASA and other scientific communities that work together to map out our world and universe.

[@SpazzyTaco-mz5cy]

so the way scientists figure out the rough number of galaxies is through a process called fermi estimation. the idea is to guess a number that is within an order of magnitude of the correct answer. this ensures a roughly correct answer while still being useful

[@ncc5]

Thing is, we see most of the stuff far away the way it was millions of years ago, and have no idea how it looks like now. A star far away could explode, and we would find out it did 100 million years later because it would take that long for the light to travel here.

[@hermeticallysealed1]

We can view the universe via telescopes, hence "observable universe". Our ability to observe the universe will slightly expand with better technology. For example, there are parts of the sky we assumed were empty, but when the Hubble was focused on the empty parts we saw thousands of more galaxies that were very faint. We can determine positions and distances through various methods, like stellar parallax and measuring Cepheid variables and supernovae.

[@GreatGreenGoo]

You can see a mountain from 1000 miles away but you will never see an ant standing on a rock up there. Its basically that concept when it comes to our inability to see planets but we can still see the galaxies they would reside in
