Couldnt tabby's star be caused by it running out of hydrogen to fuse? Aka this is what it looks like before a star moves to the red giant phase of it's life. Or has this been disproven already?
Whoa, hold up now. Didn't Freeman Dyson himself conclude that the best indicator of a Dyson Sphere would be an infrared-range emitter? Because of the heat it would have to dump? So a partial one would, say, seem to absorb light less in that range?
Sure but I mean if it's technologically active. Solar panels capturing energy, computers using the energy, waste heat produced on the side, as an example. This would result in being brighter in infrared than a "dead" object or dust cloud. I'm not saying this is really what's going on here; presumably the astronomers investigating this have found the spectral emissions to match the model for a dust cloud well, but I find it curious that everyone reporting on it is concluding that infrared means no technology, when in reality it could mean the opposite, depending on the particular measurements. In deed brighter infrared is the _primary_ suggested way to detect things such as Dyson swarms, because it distinguishes them from "inactive", natural structures.
If it was a Dyson swarm, with each individual satellite absorbing sunlight to convert into useful energy, they should glow a little in the infra-red from the excess heat it is producing, right? Wouldn't you expect it to dim less in the infra-red, or even give off slightly more infra-red if each satellite was a self-contained unit? The energy from the star's light can't disappear, so either it gets reflected (or transmitted) away from us, or transformed into another type of heat, inevitably into heat, ergo more infra-red.
Hugh Manatee yeah that would be so dope to have some interstellar neighbors that live in satellite colonies. It would still be fascinating to learn that the star system's oort cloud was much thicker and concentrated than ours
It's not a super structure. It's a debris field from another civilization not being able to resolve their differences in peace and ended up destroying all life in their system.
If you had a bunch of solid matter, mixed with dust of various densities, it would explain most of Tabby star. The brighting could also be explained if this matter was clumped together in orbit. Once the clump goes around, instead of blocking light it would reflect it.
Or maybe, the brightening is actually because the dust around it is always around it. But, the darkening is from larger groups or clusters of dust and the brightening is just the lack of dimming where there's not dust
no when they say brighting, they meant from its established normal. But i guess then the question is, are they sure there understanding of the star's normal brightness is right?
Damnit will you people please stop coming up with legitimate scientific reasons for it to not be a partially completed Dyson swarm and just let it be a partially completed Dyson swarm? Also, can someone quickly explain to me what confirmation bias means? 🤔
I think it has something to do with the church and catechism. You learn about the fairy tales and then you have to confirm that to father Bias, which is the name of the priest, if I'm not mistaken. But I've been wrong before.
Alexandre Freire hmmm... you might be on to something there. In the mean time, I think the best bet is to only believe data that validates my preconceived assumptions and ignore any of that pesky conflicting evidence. You'd be amazed at how often I turn out to be correct following this model! Haha, but in all seriousness damn I'd really love for Tabby's star to be another civilization. It's not. But I want it to be... but is not... but I still want it to be.
Cluckery Duckery I think the aliens over there are relieved and are probably saying "Phew! We threw them off the trail with the whole dust cloud story. Bwahahaha!"
"Mission Report - Third rocky planet from yellow star of solar system BFT4560/WR: We sent several probes and three crewed covert missions to the referred planet. While we found beings there building stuff, after careful consideration, we determined that there is definitely NO INTELLIGENT life on the aforementioned planet. We STRONGLY advise the use of the cloaking device to shroud our civilization towards that sector of space."
I love tabby's star and my passion is white dwarfs/type Ia supernova so this was a really cool episode for me. A question I have for the "it's aliens" crowd: even if Tabby's tar did have a Dyson sphere around it, wouldn't it still have a lightcurve that made sense, given enough observation time? It wouldn't wobble randomly or change its shape would it?
SciShow Space, An alternative is that the extra infra red is generated by the megastructure processing a huge amount of heat from all the solar collectors on the massive Dyson sphere. After all, photocells would be one of the reasons for such a massive space structure and photolectric cells generate heat.
A disproportionate dimming in the higher spectral bands is not evidence against Tabby's star's dimming being caused by a dyson swarm or similar alien megastructure. In fact, such a spectral shift would make perfect sense if there WAS a dyson swarm or similar alien megastructure . As a civilization consumes higher energy photons from a star to do work, those photons must eventually at the very least be radiated away from their system as heat, aka lower energy photons (assuming thermodynamics is absolute).
Soo the supernovas are basically like a two stage thermonuclear bomb but on a stellar scale? Cool. Also, even if it's average, our sun is the best sun.
I know a lot of stars and many are my friends, the biggest stars, believe me. Yuge stars. All those stars agree that our sun is the greatest star on earth. I know it, you know it, the stars know it, everyone knows it.
I have a question(s) for SciShow Space:1. Could nuclear bombs be used to send a message to an alien civilization?1(a). What kind/size of antenna would be necessary to receive such signals by nearby star systems (~10-20ly)?1(b). What kind of antenna would be necessary to receive Earth's normal radio broadcasts?
@1:48 That is exactly what happens but is wrongly called "gravitational lensing". Light goes through different media and is distorted. It's that simple.
i mean, i was never real big on the dyson swarm idea but seeing that light doesnt dip as much in the infrared part of the spectrum doesn't really negate that possibility at all. it's often quoted that even if a civilization captured 100% of their host star's light, we'd still see them in infrared
Tabby's star still sounds like it could be the result of two planets colliding. That could result in a diffused dust cloud, with large chunks, and that is close to what's being observed. The brightening events if real could be the cloud having a few thin spots allowing abit more light through, with the star avarage being the result of dust causing slight Dimming as default. The gradual Dimming would be dust, and the occasional faster events caused by large planet chunks floating around.
i can enjoy scishow even more now that i listen to the HFS Podcast and sort of got to know the crew a bit better. I appreciate it if you're not constantly promoting your own stuff, but i really feel like i stumbled upon a gem there. Give it a listen everybody! edit: it's not for kids, i think i should mention that...
I posit that it is possible that one or multiple planetesimals could be attempting to clear their path (in the case of multiple gravitational influencers, paths of questionable alignment even to each other) through the proposed dust cloud, thus giving small pockets where portions of dust have been collected from around its immediate gravitational influence. This could possibly give it an uneven jump in light before and after a transit. Furthermore a near but not perfectly aligned transit could give both even, and uneven dips in light depending on currently undeterminable factors.
I think this star sucked a huge amount of debris into it's orbit recently and it is swirling around the star unevenly with some of it getting sucked into the star making small explosions. In which case the question becomes, where did all that debris come from?
i may have missed something but why couldn't it be something (or things) closer to us then we expected? possibly not orbiting the star. that would explain the crazy percentage dips in light and why it's inconsistent. the dust cloud sounds great but i am just wondering.
The dust cloud theory is actually what happens. The brightening is because there are less dense and more dense parts of the dust cloud, maybe even a dust cloud not orbiting that star
a mega structure would not block all wavelengths equally. It would give off waste heat in the infrared, the part of the spectrum that is being blocked less on the spectrum that has actually been measured. therefore it could actually be a megastructure.
no. that was one of the first things ruled out. there is nothing there emitting infrared radiation. that would be REALLY easy to see with our radio telescopes.
How exactly can we assume the light patterns of a dyson swam with technology and techniques beyond our scope? Not saying it's a likely explanation but it's not like we have the definitive answer either.
was really hoping it would turn out to be a gas giant with a ring system that went all the way to the edge of its hill sphere ... just a protoplanet is cool enough, i guess
A megastructure will radiate waste heat in infrared (theoretically), thus its apparent light interference with the infrared spectrum could be explained this way.
Why couldn't it be a solar system that has recently had one or more planetary collisions, resulting in a wide range of debris with an unsettled orbit. The brightening events are when a hole opens up in the debris cloud and the darkening events are when some of the larger fragments pass between us and the star. The rest of the time there are varying amounts of gas and small particles. Even if this required an unusually large number of planetary collisions to produce enough debris, wouldn't you expect to see this going on somewhere in the vastness of the observable universe?
Is the thought still valid that the universe's expansion is accelerating? I thought more data collection through the years found the the expansion could be going really consistently, neither accelerating nor slowing.
Wait, I thought that the angle of refraction of light through the space/atmosphere border was the reason for the preference of red light during sunsets and sunrises.
Its simple. the reason why Tabby is dimming is because one side of the star is hotter than the other. This can happen when a star has two core's or, when you have a star within a star - but because of gravity, the star inside the other is slightly offset.
Someone please explain why anyone would build such a superstructure? It would take so long to build that, even if they had the resources, what would actually be worth the effort? If a civilization had gotten that far - wouldn't it be likely that their society is more energy EFFICIENT rather than energy craving? I feel that it doens't matter how advanced of a civilization you have - it just doesn't make any sence building a Dyson Sphere.
It happened in a galaxy and it happened far, far away. I mean it's 1300 light years, that's what, about 400 parsecs? Pretty sure the Millenium Falcon can't fly THAT fast!
What would happen if you smash all asteroids from the asteroid belt together. Would you get a new planet?and how would that affect the current position of the planets in the solar system?
I logged into that site yesterday ... however, I had a bad feeling as it was asking for a registration with my phone number ... why on Earth do they want my phone number ... that's really fishy .... I'd LOVE to learn wjhat all these company are doinf with out personal details !
But if an extraterrestrial civilization could make a structure like that wouldn't they make it as less intrusive and visible like a dust cloud so it didn't attract attention
1.5 billion light YEARS away but is only about 12 hours old ~ so in another 1.5 billion light years we can see what it looked like yesterday...... Hmmmm
She did a solid job on presenting. But wtf, 20% on Brilliant? I enjoy doing problems on there but I could have used the discount lol. No worries though, it's all good.
Does anyone else have issues with the video being very blocky and blurry in 1080p? It is especially bad at 1:04 and continues into the entire next scene with the rainbow background. For virtually the whole video, her hair, face, and hands (as they pop into and out of view) are all very blocky and it is extremely distracting. I have noticed this a lot recently with SciShow videos, but they don't seem to be the only channels suffering from bit-starved video. The thing is though, not every channel I watch has this problem so has anyone else noticed this?

Whoa, hold up now. Didn't Freeman Dyson himself conclude that the best indicator of a Dyson Sphere would be an infrared-range emitter? Because of the heat it would have to dump? So a partial one would, say, seem to absorb light less in that range?
Wouldn't a high-tech megastructure emit waste heat as infrared radiation?
yes and it doesn't, in fact any object near the star would also emit infrared radiation
Not if the megastructure has been long abandoned.
Verroak, yes it would, it's near a star so it would receive and re-emit energy from the host star. and there is nothing there that's doing that.
Sure but I mean if it's technologically active. Solar panels capturing energy, computers using the energy, waste heat produced on the side, as an example.

We desperately want it to be aliens cuz we don't wanna stay singles
Both parts of the episode were amazing. The shockwave on the surface made the whitedwarf explode... That is vertiginous !
It's not a super structure. It's a debris field from another civilization not being able to resolve their differences in peace and ended up destroying all life in their system.
Darn you cosmo, and your great filters! *shake fists at the stars*
Or tiny solar panels
That's depressing.
Defiler86 We should nuke it. That would teach it a lesson!
Twas the Death Star.

I GOT IT! there is a body/Bodys ejected from the system and is heading directly at us, blocking more light as it gets closer to us.
I feel stupid. I thought it said la supernova not 1a supernova.
Don't feel stupid, they should have used a different font since the channel is supposed to be trying to teach people, not confuse them.
Nice. As an undergrad at Uni, I studied synchrotron radiation from Type Ia SN. Fun to see this pop up on SciShow.

@1:48
That is exactly what happens but is wrongly called "gravitational lensing".
Light goes through different media and is distorted. It's that simple.
So far everything I'm hearing would be consistent with an accretion disk forming into planets.
Using an interesting analogy from a vet who's a friend of mine: "You can have fleas AND lice."
Tabby is back again.I mised Tabby.
If sound doesn't travel in space, what will we hear when the sun theoretically explodes?
"Those chances are dimming even more than the star is." Not only did you destroy my dream of an alien megastructure, but you did it with sass too. :(
Always so excited. I love it!
WOW!!!!!!! 6HRS OLD?????? THATS SO COOL!!!!!!!!!!!!!
I find the alien idea super silly.
It's obviously God out for a stroll.
Also, the sun is flat.
no its not your brain is
lmfao
yeah, but what about macaroni?
No, no, the earth is flat, the sun is made of cheese!
If the sun isn't hollow then where did mole people come from smart guy
It also could be that the star is incredible unstable and that why the output is so variable.
wow the host is so excited about everything
nice video

More science puns!

The brightening is because there are less dense and more dense parts of the dust cloud, maybe even a dust cloud not orbiting that star
What's the variability in SN1a due to oxygen-vs-carbon proportions...

no. that was one of the first things ruled out. there is nothing there emitting infrared radiation. that would be REALLY easy to see with our radio telescopes.
they litterally just said this thing blocks light from the star less in the infrared.
"tiny particles in the atmosphere" (around 1:55)? Surely the SciShow Space audience could cope with what they are, air molecules?
So many light puns

Sounds like clouds of something, orbiting around the star.
Nope. Clearly it's aliens.
Great vid!
Wait, I thought that the angle of refraction of light through the space/atmosphere border was the reason for the preference of red light during sunsets and sunrises.
maybe the infrared discrepancy is because a dyson swarm/sphere is emitting infrared, "cancelling out" the dimming

A Deathstar-like super weapon may have blown up a planet there.
Tabbys star: Planet caught in formation?
There was a paper that thinks what orbits Tabby's star is a giantic ring structure like Saturn's ring or that planet that has those huge rings.
Doesn’t ignition require oxygen? I get that the star has probably fused some oxygen, but enough to ignite all of the carbon?
I'm pretty sure it was assumed for a while that 1A supernovas exploded like that. That is what makes them all the same.
Someone please explain why anyone would build such a superstructure? It would take so long to build that, even if they had the resources, what would actually be worth the effort? If a civilization had gotten that far - wouldn't it be likely that their society is more energy EFFICIENT rather than energy craving? I feel that it doens't matter how advanced of a civilization you have - it just doesn't make any sence building a Dyson Sphere.
So the Death Star blew up the planet Alderaan. But that was a long time ago...
I thought that happened in a galaxy far, far away....
It happened in a galaxy and it happened far, far away. I mean it's 1300 light years, that's what, about 400 parsecs? Pretty sure the Millenium Falcon can't fly THAT fast!
For the umpteenth time, parsecs measure distance not time!
It's probably one of the many Arks. We should go visit Scorched Earth; at least we wouldn't have to pay the extra $20 if we just traveled there.
What would happen if you smash all asteroids from the asteroid belt together. Would you get a new planet?and how would that affect the current position of the planets in the solar system?
Caitlin's hair is super cute :D
Oooh so it is swamp gass ....I knew it!
I hoped that Doram, a sentient cat species, were building a giant cat face moon around the star.
On Tabby's Star, have they ruled out the brightening events being due to a companion star?
yeey for Belgium!
A slightly-transparent alien megastructure that blocks some wavelengths of light more than others? That could be a thing.
How are the stars named?
Hooray for belgium 🇧🇪
Tabby's Star! Tabby is the answer, it's cats!

But if an extraterrestrial civilization could make a structure like that wouldn't they make it as less intrusive and visible like a dust cloud so it didn't attract attention
When you say the supernova is a half day old, does that take into account the 1.5 billion years it takes for the light to reach us?
What if it's just a big planet eclipsing the Star
It's the memes of a long dead super civilization.
i call tabby's star "the sleepy star"
I thought carbon needed oxygen for ignition, is this a chemical ignition? please explain
1500 light years ... well, poop, there goes my idea of sending a probe to Tabby's Star that can look just what the hell is going on there.
but what if said megastructure is made of material that only affects certain wavelengths of light?
it would still give off infrared radiation absorbed and radiated/reflected from the star, and it's not.
Doesn't that depend on how close the structures are? How would you tell the difference?
If its not aliens Im not interested
1.5 billion light YEARS away but is only about 12 hours old ~ so in another 1.5 billion light years we can see what it looked like yesterday...... Hmmmm

Aww a baby supernova :-)
Is that an Andrew Huang drawing at the end there?
Can anybody explains me in simple language that How can dust clouds block only most of Infrared but in small amount of Visible and Ultraviolet ?
Infrared dimmed less than the others, because it's the heat emission of the equipment in the building constructed by aliens! :V
Is a proto-planetary disk not already on the table?
clvnmdr453 Proto-planetary discs are usually uniform, not highly irregular.
nah that would be really obvious.
