- In the 1950s astronomers were using radio telescopes to learn more about the heavens and they discovered something very strange. These objects, which they named “quasi-stellar objects” (Quasars for short), were small but extremely bright despite being very, very, very far away. What were they?
Well, future research revealed Quasars are feeding black holes or active galactic nuclei. Black holes are basically objects with extremely high densities and a gravitational attraction so strong not even light can escape. Well, clouds of gas and dust can orbit black holes making them active black holes that will feed on this cloud. In a process that physicists don’t yet fully understand, some material rotates fast enough that massive jets, which can stretch for millions of lights years, are formed on either side of the black hole. These jets are particles accelerated to almost the speed of light. Quasars are so bright they outshine their entire host galaxy!
There are several kinds of active galactic nuclei. Quasars are pointed at an angle to us. Blazars are pointed straight at us and radio galaxies are perpendicular to us. These are all the same thing, just different perspectives and thus different names.
Quasars are the brightest thing in the universe. To give you some perspective, quasars can be 10 to 100,000 times brighter than our entire Milky Way galaxy! That’s some serious shine.
And some quasars are found in clusters. One cluster is so massive it’s an inconceivable 4 billion light years across! Now, naturalistic cosmological models, like the big bang, predict that matter and energy will be smoothly distributed throughout the universe. That’s based on the “Cosmological Principle.” But a 4 billion-light-year-diameter cluster of super-massive Quasars seriously challenges the currently accepted models of the universe’s origins.
But this shouldn’t be a surprise because there is a historical record found in the book of Genesis which gives us a different origin of the universe, and even a different timescale. The big bang model has accurately predicted a few things in cosmology… and it’s needed hundreds of adjustments for the things that it inaccurately predicted or didn’t account for. It’s not a robust scientific theory, and I think cosmologists will make new discoveries by leaps and bounds once they finally discard the big bang and start looking toward other models. Could I suggest the Biblical one?
I’m David Rives…Truly the heavens declare the glory of God.
Big bang theory has been refined and adjusted..... Yep, that's how science works! You make a "guess" based on observation, you test it, and constantly refine it until it works. Most scientific breakthroughs don't just appear fully formed. I don't see that is a bad thing at all.
Danm i didnt come here to get preached, i alredy knew what a quasar is i just wanted to see so awesome animation, & some fun facts
I like your username.
I clicked on this video because I thought I recognised this guy from a song “debunking evolution” in favour of creationism. I was wondering what *this guy* is doing teaching science. He presents some facts, misunderstands some theories and then proposes magic.
As an atheist I appreciate hearing an argument that actually makes sense but still leaving it an open question. Also cool explanation of quasars 👍
Actually, i realy liked the twist at the end.
🤣🤣🤣🤣🤣
Came to this expecting an informative video on quasi stellar objects and quasors for an assigment i have , got a ton of preaching instead
A 162 second video contains TONS of preaching? Even when the first 117 seconds are all about the published science on Quasars? OK
Ikr?
Good explanation. Better than I watched on many science sites. Short and to the point. U dont need an 8 minute video to explain Quasars. Quasars and radio galaxies are the same thing - I didnt know this.
"God" isn't a heavenly person, it's a massive amount of energy, ya know, the energy it took to explode and become the entire universe. That energy, which has the power to create all kinds of cool things like galaxies, nebulas, stars, planets, minerals, gases, water, electricity, comets and when these things are mixed in the right way, you may get living things like we have on our little dinky planet in our little solar system floating around on one of the arms of our own galaxy. Energy is amazing stuff!
Funny because in the holy Quran 1400 years ago god says “ we have expanded the universe and we are the one who continues to expand it” so please keep your ideas to yourself
@@tekkz2963 So, "I" have to keep MY ideas to myself, but it's ok for YOU to spout off YOUR ideas.
That's called being a hypocrite.
@@tekkz2963 The only funny thing here is you came here to tell us that if god exist and he is capable to create massive quasars he would be busy making your book to convince humans for his existence 😂😂 what a joke
@@tekkz2963 mashallah bro, I was literally thinking the same thing - the prophecies mentioned in the quran, embroyology, orbits, how mountians are the pegs that hold the earth, the seas that dont mix - mashallah the quran proves its brilliance in all fields of human scientific endeavour. they struggle to find anything that contradicts it - when they "supposedly" do - its either a misquoted, non-sahih hadith, or a deliberate mistranslation of arabic
Speaks in terms of billions of years then refers to the biblical time scale. Sorry but I prefer none conditional theories and beliefs, the type that don't condemn me for disbelieving you'rs and similar doctrines.
He spoke of billions of light years away. He never said that the Earth existed for billions of years, there’s no contradiction here; but of course, believe as you will. The Bible doesn’t force one to believe anything :)
@dorianfranklin1399
Fair comment. The Bible is a book, and for centuries it has been used as a tool to condemn the 'none believers', infidels and believers who's interpretation of the book differs
2:00 I was like WTF 🤣🤣 was taken aback there then I noticed the channel’s name LMFAOOO What a twist babe?!
I‘m, like, 6 years late, but can you list your source? I am writing a study about quasars for school and this video is what helped me understand, what exactly those jets of the quasar are. I‘d like to read the paper myself, too, so I can improve my own study. Thank you very much !
Blackholes are Important!! I know what a quasar does and why.....but someone who see only objects won't even guess it!
Ok but how is it made??
They are not made. They are just blackholes that have become active due to feeding
Even the scientists don't know yet
This is confusing.
I did a little more research and it seems a quasar is the result of two super massive black holes clashing with each other? And supposed to be one of the strongest things.Let me know. Also is it called something when two entire galaxies collide? Thanks
Starts off informative, then wanders off into magicland as he presents a hypothesis that’s completely untestable and therefore utterly useless.
How would one test any hypothesis on a cosmological scale?
@@charliecrowe6606 we test hypotheses on the cosmological scale all the time. But his hypothesis isn’t on the cosmological scale. It’s in the magic realm. Your question should be, “how would one test any hypothesis in the magic realm?”
@@joenelson2170 Actually we are only able to test, on a cosmological scale. an inordinately tiny sliver of the cosmos. The presuppositions by which we work, the extrapolations, and the rest of the cosmos we can't test, we assume conform to the conclusion of our hypothesis based on faith. If a person is religious, atheist, agnostic or muddle headed they all to a certain degree operate on faith. Or as you c all in magic.
@@charliecrowe6606 not everybody relies on any degree of faith. Faith is just people plugging in answers where one should say “I don’t know.” Anybody who is comfortable saying “I don’t know” doesn’t ever need faith.
@@joenelson2170 you stated that "Faith is just people plugging answers where one should say 'I don't know'". Can you know that for certain? Can you know all that can be known about all people and their motivation? You seem to be a pretty bright guy, but I wonder if you are really that knowing. You might be better to say, "I don't know why people have faith" Then you might explore why some people find faith the most reasonable option.
3000 years ago first dynasties in egypt were almost at the end. Universe didnt start 3000 years ago
I've never heard of a quasar. Thanks for this, David Rives. God is awesome
If you can get your hands on a short wave radio, you can hear quasars.
Of course you haven't 😂
Are quasar so massive as you mentioned? You didn’t explain what actually is quasar or the video is too short to explain. Hope see you in another video with better explain
A quasar is extremely massive indeed as it is the byproduct of usually two black holes colliding and as such the matter found orbiting them is shot out at super high speeds. A quasar doesn't have a definitive size but it's very well bigger than our solar system as some quasars can stretch for thousands of light years.
When you imagine God creating light, do you not imagine a big bang?
Yeah and after the big bang he created the devil, a talking snake and cursed humans for eternity 🤪
i am now a blieber
The heaven absolutely declare the Glory of God.
I think you are a bit upside down here. Tell me, if you wanted to explain the Big Bang, planetary formation and a universe in terms people living 3000 years ago would understand and accept, how would you do it? Something like what we find in Genesis, right? There's even a verse about Reionisation (Gen 1:4)
So, if you choose a biblical approach then you are making a serious underestimation. "In the beginning God created the heavens and the earth" (not The Earth, we note). It doesn't say how he made it. How do you assume he made it? Or do you think science is a good way of finding out?
The biblical god is not real the mathematical law isore powerful than him therefore the biblical God is not the God
So is the quran god allah. Some people fool us before 1400 and 2000 years ago
Bible is word of Paul
Quran is even more accurate
Why are you two bringing up religion and ARGUING ABOUT IT - you know, how religious wars have started - on a science video?! Iii
@@Mscape7 See thats the difference. You take Christianity or Islam or any other religion as just religion.
There's no religion Islam. We take Islam as a Way of Life.
@@abdulmoiz5987 It is a religion.
@@Mscape7 Its not....Its Deen. Lookup what deen is
@@abdulmoiz5987 it is a religion and you came on here arguing it is bettee than Christianity, which is also a religion. That isn't productive. Neither has anything to do with the subject of quasars.
The bullshit starts at 1:59.
Before that it's fairly good.
