That's not a Christian conspiracy.  Most Christians ignore all such prophecies.

Just another Protestant misinterpretation of the Bible. Various fundamentalist Protestant churches have "predicted" the end of the world at least 50 times, since they came into existence a couple of hundred years ago. However, the original and true Christian Church (which includes well over half of all Christians) accepts what Jesus Christ said, which is that no-one would know the time, that He would come "like a thief in the night", when we least expect it. Therefore, as soon as anyone makes a "prediction", we can be certain it won't happen then.

The twenty first century I don’t know it might be! The thing is they are handing out numbers in the virus with a number sent be Bill Gates. Who may be wiring for Satan 

Just Jupiter and Saturn are "aligning"

from the point of view of Earth

(so you could say: all three are aligning).

The other's aren't

but have in the past

with all of those same "signs" in addition

and nothing happened then.

It's just another one of your conspiracies.

The Virgin Mary has told us those who recite her rosary will be granted signal graces.

Just another Nicolaitan False Doctrine being taught.

Planetary alignments have occurred in the past and will occur in the future. You can use the lengths of the year for each planet and get a rough approximation for when these alignments occur. 

It could happen but Jesus said that just as people ate and drank and had marriages up till Noah had the ark made it will be the same for us people will live their lives as if there is a tomorrow they will eat and drink and be given in marriage the end of the world will come like a thief in the night and the elements will melt and the earth will burn up. we are never promised tomorrow that is why it is said harden not your hearts repent and obey the gospel for tomorrow may never be. Thanks for the question.

Well, it's certainly not a Christian conspiracy, but probably someone's conspiracy. People claim that every year. It has nothing to do with Christians. They were almost right a few times. Y2K bug, for example, was indeed a deadly threat to technology and would have destroyed banking institutions, crashed planes, and all the crazy stuff they said. By 2000 our world had become far more integrated with computers than we expected and so most of the world was operating with systems that would crash when the clock turned over to 2000. The threat was avoided by a decade long effort of programmers weeding through millions of lines of code, some going through obsolete programming languages, to fix it. Again, nothing to do with Christianity, but it was a real threat that could have destroyed us. 

Now the 1982 planetary alignment, which I believe is what you are really talking about, known as the Jupiter Effect, was a real event. It was predicted back in the 70s and scientists really had no idea what effect it would have on our planet, or our solar system. Many predicted that it would throw our solar system out of balance, or that the gravitational effects on earth would cause extreme results. Again, it had nothing to do with Christians. However, the planets did line up as predicted, but not much really happened. There were some measurable gravitational phenomena, but not enough to throw any planets out of orbit, or cause anything we would notice without instrumentation.
