The Middle East is the single best case study for this topic. As a region where continents, religions and cultures collide it has been ruled, conquered, and reconquered like no other place on the planet. There could be, and in fact have been many books written on this subject but for the sake of this we will just look at your specific questions. Does it ...

The Romans were experts at this. The procedure was as follows. Invade state, conquer it. Do this peacefully if possible with displays of leniency backed by overwhelming force. Allow freedom of religion, provided the populace also gives loyalty to the emperor. Build infrastructure, roads, aquaducts, promote trade and ensure lots of people get rich. Romans ...

It at least partially depends on how brutal you are willing to be. There have been plenty of cases in history where the invaders killed every male over a certain age, enslaved the women, and raised the remaining children as their own. In those cases the conquered culture is pretty much completely eliminated within one to two generations. http://en....

It's not stated in the original question, but the implicit assumption that seems to be at work is that there are no other "godlike entities" around to interfere. If that's the case, then we're looking at our world with the one change being this thing arrives and starts being all godlike, yes? Well, in that case, it doesn't have to worry about the Abrahamic ...

Easiest way to convert all of Judea at that time: Send a prophet who passes their "tests for a prophet", outlined in their religious text. Most notably, the test of a prophet is in Deuteronomy 13:1-3 and Deuteronomy 18:18-22. Now then, the rule here is that a true prophet can predict the future accurately, confirms his message with signs and wonders, and ...

I think massless is the way to go here. To make the journey to Mars in three hours, we'd need to accelerate the projectile up to about 0.08c. That may not sound like a lot, but that's 25,070 km/s. For a comparison, the fastest ever man-made object to date (not counting the nuclear powered manhole cover) is the Juno probe, which pulled a blistering 40 km/s ...

Does it need many invaders? This depends on "how" the invasion takes place. A big military strike versus a well armed(at least same quality of armor and strategic knowledge) nation is difficult and needs some advantages like the element of surprise and a very fast strike of combined forces (see Blitzkrieg for further information). This is probably the most ...

Most of these concepts aren't as clear-cut as we tend to portray them from a distance. For example, if a country is conquered, and changes its language completely within 20 years, then either it was already very closely linked with its invader (like Austria/Germany), or the assimilation is superficial and the original culture considers itself to still exist ...

Better than eliminating him would be to project a wormhole from Earth (or Earth orbit) and either funnel him into the mouth of the wormhole or have a "snatch squad" jump out and grab him, pulling him back into the wormhole (and to custody on Earth) in front of a live audience and all the people who have logged on to see the podcast live. Thos would most ...

Just keep Rome healthy (The question is rather broad, so I'm going to generalize a bit. Okay, a lot. Bear with me.) The distinction between religion, culture and politics is a relatively modern invention. To the people you're interacting with, it is simply their way of life, and coming into contact with a different one is something that the Romans were, ...

Before Christianity came along, the Pharisees, the most dominant sect of Jewish leaders, were already cooperating with the Roman government allowing Roman culture to subvert the bulk of Judaism. The Gnostic Jews were scattered to the wilderness where they cut themselves off from society making them harmless, and the Zealots who actively opposed Roman ...

(1) In 45 BCE Judaea was not part of the Roman empire. It became a Roman province half a century later, in 6 CE. (2) By the middle of the 1st century BCE the Roman official state religion was already on life support. Public theological debate with Jewish priesthood with consequent public subversion of Elijah's Jahweh vs Baal challenge. Why on Earth would ...

The question of focusing the laser needs some expansion. Aiming, too. First, distances. Since the average distance of Mars from the Sun is 228 million km, and for Earth it's 149 million, at conjunction the distance between the two is 79 million km, and we'll use this as the easiest example - call it X. In order to get a small focus spot (diameter d) for the ...

When Greg Bear wrote about a separatist Mars movement in his novel Moving Mars, Earth's main weapon in the end was "locusts": nanotech fabrication systems planted surreptitiously on the Martian surface well in advance of any rebellion. "How do you control an entire planet from across the Solar System? Seed it with nano factories that can build a variety ...

If you have massless projectiles you might be able to pull it off, since a massless projectile would be able to travel at the speed of light. The average distance between Mars and Earth is around half an hour at the speed of light. So you would have about that long between when the shot is fired to when it hits. Because it's massless and moving at the ...
