Evidence For a Major Kilonova Event Near Earth (3.5 Million Years Ago)

Thanks for continuing to be awesome Anton ❤

It is "wønderful" not "æwësome".

[@nooneisback]

Honestly one of my favorite channels. Most channels either treat their viewers as children or go way too technical for anyone that isn't in the field. These videos are informative, yet you don't need to go through 10 minutes of highschool physics.

[@nunyabiznez666]

Crazy to know that something even hundreds of LIGHTYEARS away can still pack enough power to kill anything in its path 😮 0_o

[@douglaswilkinson5700]

A GRB produced by a type II supernova up to 6,500 light-years away would cause a mass extinction on Earth. *However,* these GRBs are collimated into a very narrow beam the width of our solar system (Dr. Stan Woosley, UC Santa Cruz.)

Hi Anton, I love your new kilomicrophome

[@WaterShowsProd]

The only reason for it to have driven human evolution would have been if it had created enviornmental pressure which would be detectable in the geological record, and untied to any other cause. I think it's more interesting to consider how something massively powerful like that can happen relatively close by and yet have little to to no effect on us.

Every answer still brings about more questions. Neutron stars look so bright in your simulations, Anton, that it is hard to remember they are not easy to find. Thanks for this illuminating update!

[@toughenupfluffy7294]

If it was 500 light years away and it's taken 3.5 million years to get here, that means the material was traveling at ~95857.79 miles per hour relative to a stationary Earth.

[@Ashley-jp4nn]

But the earth is only 6,000 years old :(

[@Lyxtwa]

I dunno if the vid said it took 3.5 million years to get here. Just that the event was 3.5 million years old. As in the sample was deposited roughly 3.5 million years ago on earth.

[@danguee1]

[@AceSpadeThePikachu]

The possibility the kilonova are much more common than previously thought is both a bit unsettling, but also exciting. Unsettling because of the risk of one going off near us and wreaking havoc on our atmosphere, but exciting because it could mean many if not most of the star systems we see out there could be enriched in heavy elements; a characteristic thought to be vital to a planet supporting life. I am curious however if there is any possibility this detection of Plutonium could actually be contamination from nuclear tests in the last few decades.

[@damianousley8833]

Given that the sediments can be geologically dated, and the Plutonium 244, only is a naturally occurring element from stellar events. The Plutonium 244 is not man made. As human operated reactors produce Mainly Pu 238, Pu 240, and Pu 242, which have longer half lives than most Pu isotopes. Before the nuclear weapons program, the only naturally occurring Plutonium was Pu 244. It was only a very minor component in thermonuclear fallout. However having a half-life of 80 million years there would be very hard to detect primordial Pu244 from the solar systems creation. Most man-made Pu isotopes stop at Pu 243 which is short lived. It is interesting that man did not create Plutonium solely and nature had already done so in supernova type events.

[@AceSpadeThePikachu]

@@damianousley8833 Ah I see. Fascinating.

[@BWP-u3y]

Besides all the amazing things about our wonderful universe that I learn from your channel... I appreciate your attention to detail, on what audio production you do. How do you side-address ann SM7b, and still get a nice, balanced low-end on your voice? NOT being 'negatively critical', or anything like that, just would like to know. Looks good, AND sounds good! How you do that?!? 😀 Is it a different mic we're actually hearing, or is there some post production magic going on? Thanks for all you do for us seekers, and much love to you and yours this holiday season!!! 🖤

[@mrrob7531]

Awesome video Anton

[@OrangesodaTR]

6:43 Considering how important all the elements heavier than iron are for developing complex life and complex technology, seeking out kilonova events would probably be the most efficient way of discovering life in other stellar systems. Maybe even intelligent life. Whatever device you're watching this on requires a multitude of elements heavier than iron, as do your bodily functions.

I wonder if we could have a mesh type of device in space that could collect elements. Then we could have a factory to develop those metals and such. We could use that to build more right in space.

[@a.westenholz4032]

This does make me wonder if we're in general overestimating to some degree the deadliness of the universe. Not that a kilonova can't be as deadly to a planet as thought, but if we on earth could be so "close" to one and be relatively unharmed, then it certainly leaves food for thought.

[@teardowndan5364]

There isn't much point in worrying about mass extinction events of cosmological origins when we don't have the means of inter-galactic travel necessary to avoid them.

[@willikappler1401]

Thanks Anton! My first thought was: if two neutron stars collide, the result is most likely a black hole. Does that mean that there is a black hole relatively close to us ? (only a couple of 100 light years away...)

[@johnchase2148]

Another possible theory is our sun as a mini-nova . From dust to dust and in motion is just so magnetic.

[@caejones2792]

I wonder what the spread on such a debris wave would be. We only found the one deposit, right? Implication being that it was the only debris thick enough to make it through both the atmosphere and ocean, which also hit Earth. But does that suggest there were other bits of "you got kilonova in my supernova" that passed through other parts of the Solar System? And if so, what are the odds of there being additional deposits on places like Mars, or the big 7 moons, or Mercury?

[@nzcyclone]

A very good video Anton. Thank you :). I know this is thinking outside the box so to speak. But, could this Kilonova event or something similar be what stripped the atmosphere from Mars?. Earth got hit by the peripheral blast wave and not directly hit so to speak, but, Mars got directly hit?

[@cryoniczz7073]

[@nkronert]

It should be possible to send something similar to a mass spectrometer into space that can directionally detect specific ions like that are flying towards earth, thereby giving us a direction to look at for kilonova remnants.

Random thought: If we managed to travel lightyears away by manipulating the fabric of space such as a wormhole and we looked back at earth, would we see earths past? Could we actually look back in time?

[@TheAncientAstronomer]

Yes. If you could travel instantaneously from the earth to a point in space, let's say 10000 lightyears away and you'll looking back from your current position, then you would see the earth as it was 10000 years ago.

[@tomholroyd7519]

The animations always show neutron stars orbiting. Is it possible, if a neutron star were coming in at a much straighter angle, they could just hit directly without even one orbit? Less energy expended in all that gravitational wave generation, should be much bigger boom

[@banalresentive6523]

Not impossible, but the odds of two neutron stars colliding that AREN'T a double star are very small. It would be nice to "catch" such a collision with detectors when they happen SOMEWHERE in the visible universe, but likely won't happen in our lifetimes and won't be nearby.

[@curtisdecoste9345]

Is there a type that the initial blast would be visible long before the more damaging effects? Imagine knowing exactly when you’ll be obliterated because you can see it coming…… Space is so terrifyingly destructive our only saving grace is our extremely short existence. 😂

[@douglaswilkinson5700]

The extremely large distances between celestial objects in our neck of the woods -- the Orion Spur -- also minimizes the chances of Earth experiencing a mass extinction.

Anton: There had to be some phenomenon that triggered the “Christmas star” followed by Magi because it observations appear in several texts. What did that ~2000 years ago?

[@sideeggunnecessary]

It appeared in "several" texts, that's basically science! 🤡

[@filonin2]

Had to be, especially since we know the entire event was fabricated since those texts speak of a census requiring everyone to return to their homeland to be counted, which never happened and is not how census' work. The part that sealed it for me was the anonymous authorship and claims of supernatural beings, because nothing says real like magic and visions.

[@davegold]

Comet? It's something that was bright in the sky for a few weeks without much evidence of any other effect on Earth.

[@jesusramirezromo2037]

Pretty sure there's only one original text lol

[@olencone4005]

The "Christmas star" is only described in the Book of Matthew, and even then the details are fairly light. If it were real and not just a literary plot device, then it could have been something as simple as a planetary alignment... Jupiter and Venus were in a conjunction in the spring of 2 BC, separated by less than 1 degree -- which would have looked like an exceptionally bright star just above the horizon from a vantage point in the Mediterranean or Middle East. Chinese astronomers recorded a supernova in 5 BC, but its position would have been well overhead and a bit north. Comets are also a bit unlikely, as they were widely viewed as harbingers of evil, not good tidings, and they remain visible for a fair bit of time. Personally, my money's on it just being a literary device to enhance the storytelling.

[@Captain.AmericaV1]

Wasn't there a kilonova a billion light years away that nearly destroyed our satellites?
