What is a Quasar? | David Rives

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 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.

[Disphora]

As an atheist I appreciate hearing an argument that actually makes sense but still leaving it an open question. Also cool explanation of quasars 👍

[mwhitby]

Actually, i realy liked the twist at the end.

[OmarTheAtheistAziz]

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

[leonard]

Came to this expecting an informative video on quasi stellar objects and quasors for an assigment i have , got a ton of preaching instead

[kajacallisto]

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 !

[WERob-tosp]

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.

[eardwulf]

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.

[Volcanotree]

Blackholes are Important!! I know what a quasar does and someone who see only objects won't even guess it!

[moonbear]

"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!

[Demitchii]

2:00 I was like WTF 🤣🤣 was taken aback there then I noticed the channel’s name LMFAOOO What a twist babe?!

[KiranSharma-zqcl]

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

[surrealsoupuniverse]

3000 years ago first dynasties in egypt were almost at the end. Universe didnt start 3000 years ago

[violetlove]

I've never heard of a quasar. Thanks for this, David Rives. God is awesome

[elainasmith]

When you imagine God creating light, do you not imagine a big bang?

[jackstar]

The heaven absolutely declare the Glory of God.

[joenelson]

Starts off informative, then wanders off into magicland as he presents a hypothesis that’s completely untestable and therefore utterly useless.

[stephenkebbell]

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?

[abdullaharenas]

The biblical god is not real the mathematical law isore powerful than him therefore the biblical God is not the God

[jimmorrison]

The bullshit starts at 1:59.
Before that it's fairly good.
