“The universe is under no obligation to make sense to you.” ― Neil deGrasse Tyson

[@internetwanderer9053]

@Marco Creen Nice job by trying to sound smart

[@Revstarallstar]

@Marco Creen shut up

[@internetwanderer9053]

@Marco Creen Who said I was butthurt? I really don't give a shit about you. What I can't put up with however, is when someone is telling *lies* .

[@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 :)

[@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.

That’s the same kind of situation we have when looking at the observable universe vs individual planets and stars.

[@ChaseTheVase]

Nice analogy

[@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.

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.

I think a lot of people don't take into account that the point of telescopes in space is literally to "look outwards" like a camera and send back information to us on earth..... Eg. Your phone camera is in your hand taking a pic of a person standing across the street at a certain distance away and the closer you move with your phone the more things the camera sees, like other people and things behind and around the initial person who was across the street (telescopes are always moving around in space so they always gather more new information until their lifespan ends)..

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.

It probably doesn't go on forever but honestly, that doesn't matter because we can never get there anyway.

[@GPReimer]

Also keep in mind that the light from a galaxy that’s say 65 million light years away would be the light that was projected from 65 million year ago and not a current representation of what’s actually there at the time we are seeing it.

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.

My god why are people such science snobs in the comments section? Clearly astronomy and astrophysics are subject matters that're quite beyond the couple's normal realm of knowledge, but that is true for the vast majority of us as well. Their reactions are completely understandable from a layperson's perspective. Wouldn't it be better for those of us who're more in the groove of these things to just encourage them to read up (if they're interested) or perhaps quickly explain how astronomers can and have studied celestial bodies or make very good theories on them even if they're millions of light years away?

“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

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

[@Native_Beats_]

There was once a universe where life developed on every planet. It was carbon based, silicone based, water based, and plasma based. Intelligent life formed everywhere. An innumerable amount of languages, paintings, stories, and songs were created. They invented things like electricity, conditioners for various things, and dabbing. These planets made contact, created more languages, religions, and made peace. Finally, after the universe was colonized, the galaxies were rearranged into perfect geometric formations. Universal peace was achieved. We all spoke a common tongue, and had friends of all walks of life. However Due to a quirk in our evolution, due to an abundance of resources, we never learned how to think for ourselves.. Food was ate, but wasn't enjoyed. Movies were watched, and nobody laughed, cried, or made shitty comment based reviews. Once it was time, the universe collapsed in on itself, and there wasn't a single moment of sentience throughout all of existence. -Exurb1a

[@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 👍

[@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.

[@gmail9384]

To answer both of the girls' question i think 1. they can piece together what all the neighborhods of galaxies look like by using hubble telescope and 2. When she asked if we can see all that observable universe how come we cant see planets aswell, we can see planets and have found planets, but regardless, planets are smaller and much harder to spot. The galaxies are so much easier to see because they are so big and bright. Trying to spot planets throught the universe is like trying to spot individual grains of floating sand in a deep dark ocean. You might only spot one every once in a while

[@garymcatear822]

The universe is a sphere with a hollow spherical center consisting of absolutely nothing, it is forever expanding outwards in every direction.

[@Aidancav16]

The reason we can't see these places outside of the Observable Universe is because in all of our history the light from the places outside hasn't reached us yet. Keep in mind that light is the fastest thing in existence.
