So a power beacon sent from a (possibly) Kardaschow Type II civilization 95 light years away. Do we really want to meet the cats? I'm gonna go play some guitar.

I read in a different article they believe them to be a Type I civilization similar in technology to earth.

So a Kardashev Type II civilization as theorized "can harness the energy of the entire star (the most popular hypothetical concept being the Dyson sphere—a device which would encompass the entire star and transfer its energy to the planet)."
A Dyson sphere encompasses the entire sun for the purposes of using that power to send a beacon into space...
Okay but if you can encompass an entire sun for the purposes of broadcasting a signal into every direction of space, wouldn't you be capable of doing more than that.
That by it's self is a huge undertaking. Wouldn't planetary exploration be a tiny project in comparison?

Yup, that scale is just silly.

I'm more curious where they would get the raw materials to encompass and entire star.

Well the obvious answer is from harvesting materials from other planets, moons and asteroids. But the concept of doing this is as bad as the concept of creating a death planet which harvests the energy from the star in a solar system to blow up another planet. (Starwars most recent movie).
They had the ability to make the "deathstar" before, why now do you need an entire planet.
Planets are very difficult to move. It's not as if you can put a motor into it to move it like a space ship. And even if you could, and the planet stopped spinning it's atmosphere would disappear.

@aidan_walsh Already gave the proof of how silly the original article is in the first place. Journalists and scientists should never mix!

OK We'll go on this tangent - the new "deathstar" from the new movie doesn't move. It stays where it is, it just shoots an energy beam across light years and destroys other planets. Frankly that whole thing was just DUMB! and with that I must walk away before I just cry over how bad things like this were in the new movie.. and why? for the love of star wars? why did we need another deathstar for a super weapon? and why this crazy impossible thing.
As for the spinning an no atmosphere - I don't think that's right. We'll still have gravity even without rotating (look at the moon), but we wouldn't have the magnetic protective field that saves us from solar radiation, so the planet would be a lot warmer, and the atmosphere would boil off, maybe that's what you mean?

Because this is the Disneyification of the franchise. Although really, Lucas hated it so much that it couldn't get any worse than what he did.

A planets spin creates a magnetic force around a planet, that magnetic force keeps solar winds away from the planet which allow the atmosphere to stay on the planet.
Gravity isn't capable of keeping an atmosphere to a planet by it's self.

It's spin plus a certain type of core.

From nearby planets. Although more likely they would build Dyson swarm (solar panels and mirrors in orbit around the sun) rather than sphere, sphere is almost impossible from engineering point of view. Gravity forces are just to strong for any material to withstand, and even a slightest nudge towards the star, from being hit by an asteroid for example, would create even more tension and break the sphere apart.
We actually could build Dyson swarm by harvesting Mercury, Venus and Mars, but what would we use all that energy for?

Just a point of clarity the moon does rotate/spin on its axis. It just takes ~27 earth days.

The moon rotates. If it did not, we would not see the same face all the time. Basic physics man.
Gravity is a function of mass and has nothing to do with rotation directly. Our perceived 1G on earth involves rotation since the earth is rotating and trying to throw us off the surface while gravity is attracting us "down".

The movie's plot was so horrible in that the concept of "a planet can't be blown up from a well placed torpedo" But when you suck the energy out of a star and kill the star, you've killed the planet.
The star would likely go super nova and blow away the entire solar system.

Aww thanks, That I didn't know - I've always hear that the moon was spin locked with the earth.

I really wish they had just made the Thrawn trilogy into movies instead of making A New Hope 2.0.
