I believe that man's desire to learn more about the universe he lives in does not go against God's will. He has gifted some people with incredible brains and He expects them to use those brains. However, God expects us to use the gifts and talents He's given us in a way that honors and glorifies Him. So, the question should not be whether we should be accelerating subatomic particles, but WHY are we accelerating subatomic particles. If we are doing it for righteous reasons, then so be it; however, if we are doing it with evil intent, then it will not be blessed by God. The people that were building the tower of Babel weren't doing anything that was wrong, on it's face; however, they were doing it with evil intent, in that they wanted to be equal with God. Because of that, God scuttled their plans. So, God knows the hearts of the people that are accelerating subatomic particles, and He alone will decide if it's something they should be doing. As far as unleashing the devil and demons goes, the devil is already the god of this world, and he and his demons are already quite present here. That is why we are already involved in spiritual warfare, as believers.
