1. The size of said simulator would have to be size of the Earth or Bigger at least 12,000 KM - why you ask? - That is simple and can be explained with an analogy - I live in Australia and I have a friend in New Zealand, during the day we both see the sun, however my friend sees it in a different position in the sky than me because the Earth is rotating and there is a difference in time. If your simulator wasn't at least the size of the Earth, people in different parts of the globe would be able to see around or past the simulator.
2. That's OK, it;'s very big but it's in geosynchronous orbit. - sorry that doesn't work either, simply because anything in geosynchronous orbit stays over the same point on earth at all times - so again people would see around it .
3. So now you have to find somewhere to put this simulator so it hides the sun but isn't being dragged back to Earth by gravity (you have heard of Gravity?) so you put it 1.5 million KM (a KM is about 0.6 miles - in case you live somewhere that hasn't caught up with the rest of the world and our metric ways) out in space at what is called the L1 point or Lagrange point where the Earth's gravitational and the Sun's gravitational field nearly cancel each other out and it's easier to keep something in the same spot (who wants to be moving the simulator all the time?) So let's sum up for you - we have a 12,0000 km wide disc floating out in space that is some sort of huge light globe (can't be a mirror because if it's in front of the sun and therefore has nothing to reflect) it is 1.5 million km out in space, so all you need to worry about is if something goes wrong and it breaks down (most of these "truther" channels agree that it is breaking down). Should the breakdown happen, you had better hope that the sun's gravitational field grabs it first because if it decides to come hurtling towards earth, you wont have to worry about Nibiru, because something the size of YOUR simulator (NOT MINE) WILL NOT burn up in the atmosphere, it will break up and spread a large swath of debris across the planet - and the chunks will be that big it will be no good to "Duck and Cover". .... and let's just conveniently forget how much such a project as building your simulator would cost, let alone the number of launches and workers it would take to get the parts into place, also that it was built with anyone seeing it under construction, (maybe they did that at night? - oops that wouldn't work either). With the currently available heavy lifters available let's look at some details and real math. suppose the sun simulator is 1 mm thick and similar density to water of one ton per cubic meter (I think most lenses would sink in water) then with radius 6,371 km then the volume in cubic meters (and so mass in tons) is 0.001*PI * 6,371,000^2 tons or around 127,500,000,000 tons. Google calc here 0.001*PI * 6,371,000^2 If both US and China were doing say 1000 launches a day then it would take them 127,500,000,000 / (10*2000*365) = 17.500 years to complete the project. If both were doing a million launches a day, or a launch on average every 11.5 seconds, then the construction would still take 17.5 years. Obviously there is no way you can launch a rocket every 11.5 seconds from the same launch pad. Instead since the turn around time is bound to be more than a day they would both need millions of launch pads to do it in a reasonable timescale. And - that doesn't explain how this one millimeter thick "lens system" achieves what they want - and you have to figure out how to keep it from folding up or moving away from its unstable equilibrium position at L1 - and it also has to be several times the diameter of the Earth to match what they claim to be its size in their sun halo photos. And think what an astronomical spectacle it would be, with millions of spaceships going up there every day to ferry all the materials up to make it, and the lens or mirror gradually unfolding in a space construction project billions of times more ambitious than the ISS. It’s just an absurd idea.
