[url]https://www.newscientist.com/article/dn28786-comets-cant-explain-weird-alien-megastructure-star-after-all/[/url] [QUOTE] Now [URL="http://www.phys.lsu.edu/newwebsite/people/schaefer.html"]Bradley Schaefer[/URL] of Louisiana State University has discovered that the mystery goes even further. When Boyajian’s team studied the star, they looked at data from a Harvard University archive of [URL="http://dasch.rc.fas.harvard.edu/project.php"]digitally scanned photographic plates of the sky from the past century or so[/URL] to see if the star had behaved unusually in the past, but found nothing. Schaefer decided this unusual star deserved a second look. He averaged the data in five-year bins to look for slow, long-term trends, and found that the star faded by about 20 per cent between 1890 and 1989. “The basic effect is small and not obvious,” he says.

i may be missing the joke here but the article is saying that the star is possibly either surrounded by dust clouds, comets, or potential "alien megastructures", not a dyson sphere
I'm not sure what a [URL="https://media.licdn.com/mpr/mpr/shrinknp_800_800/p/7/005/09a/27c/2eb99ef.jpg"]vacuum cleaner[/URL] would be doing in space
[QUOTE=Bathtub;49547492]i may be missing the joke here but the article is saying that the star is possibly either surrounded by dust clouds, comets, or potential "alien megastructures", not a dyson sphere[/QUOTE] A Dyson sphere is a specific type of megastructure, and since we obviously didn't make it, it would be an alien one.
[QUOTE=Bathtub;49547492]i may be missing the joke here but the article is saying that the star is possibly either surrounded by dust clouds, comets, or potential "alien megastructures", not a dyson sphere[/QUOTE] I can't think of any other kind of "alien megastructure " to surround a star with.
I thought it was recently debunked as a new natural occurrence ? (Forgot what it was)

Thats what the thread title was getting at, that aliens are possibly in the process of building a dyson sphere / bubble (A bubble is different, its several objects orbiting the star in a synchronized pattern, so none of them ever hit eachother) of some type.
[QUOTE=echo78;49547513]I can't think of any other kind of "alien megastructure " to surround a star with.[/QUOTE] i mean it's not like we know of any existing alien megastructures, we're going off our own hypothetical knowledge of what an alien species would create plus the title of the thread is saying that the star itself is a dyson sphere, it was just poorly phrased
[QUOTE=echo78;49547513]I can't think of any other kind of "alien megastructure " to surround a star with.[/QUOTE] Space stations? Solar satellites? I mean if it was a Dyson Sphere we wouldn't see any light from the star. It only dipped as much as 20%, so maybe a massive space station or satellite or large numbers of either.
[QUOTE=Bathtub;49547492]i may be missing the joke here but the article is saying that the star is possibly either surrounded by dust clouds, comets, or potential "alien megastructures", not a dyson sphere[/QUOTE] Dyson swarm really, its like the sphere but made up of a swarm of large solar collectors instead
The problem with this is, why would an alien race build a dyson sphere, they are incredibly inefficient, for example a Dyson sphere that would be habitable in the inside and say 10 miles thick would require roughly 25.173479 quadrillion tons of Titanium, which is an absolutely ridiculous amount of material for something that will be destroyed when the star dies, unless they make it portable, which would require even more materials and fuel. By then it would be more worth it to just have giant fusion reactors that power everything. I'm sure they have plenty of those if they're attempting to build a dyson sphere for some reason.

I thought that even with better conversion efficiency than we have now, a mega-structure would radiate a lot of infrared because of the waste heat. And if I recall the infrared emissions from here looked normal.
If this is confirm to be a dyson sphere, it also confirms the theory of a dyson sphere. I wonder how long it would take for a message to reach it? It would have to be reality close for us to see it with scopes from 1890's? Although people at one stage thought Andromeda to be a gas cloud and that was discovered fairly early.

According to Wikipedia, it is 1480 light years away. So it would take 1480 years for a message to reach it. Then it would take 1480 years for a reply. Hopefully the reply would be peaceful, and not the full energy collection capacity of their dyson sphere, focused on our planet for a year, as I'm pretty sure that would kill everything on earth.

Isn't there stages leading up to a full dyson sphere? Like a dyson swarm or some shit?

Now that NASA has loads of money they need to research and build a super engine so we can see what it is.
[QUOTE=markg06;49549188]Now that NASA has loads of money they need to research and build a super engine so we can see what it is.[/QUOTE] Would have to either warp space or surpass the speed of light, because this star is 1480 light years away, sadly. Gotta get them wormholes
[QUOTE=markg06;49549188]Now that NASA has loads of money they need to research and build a super engine so we can see what it is.[/QUOTE] Even at the speed of light, which we cannot go faster than (and realistically can only get close to), it would take just under 1,500 years to get there one-way. Don't get your hopes up.

It's a great endgame "might as well" structure.

Add in a thousand or two years more because light speed limitations, and then we're probably at around 5,000-8,000 years at least to reach some nearby star system, which still doesn't sound like a bad idea to construct a big number of sub-light speed colonization ships, and send them all over the galaxy to predetermined destinations. Communication between these colonizes, and the Earth, could probably be established as well, but otherwise they would be effectively isolated, until we come up with...something faster. Or, would that be suicide?

Quantum Entanglement in quantum computer based communication networks could, in the future, be used to communicate signals between two linked systems any amount of distance away from each other instanteously. The only problem is physically getting the receiver there in the first place.
