Warp Drives May Come With a Killer Downside

An anonymous reader writes "Alcubierre warp-drives (theoretically) allow rocket ships to travel faster than the speed of light, while staying within the rules of Einstein's general theory of relativity. New research (PDF) has shown that as such warp-drives zip through the universe, they gather up particles and radiation, releasing them in a burst as the warp-drive slows down. This is bad news for family and friends waiting for the ship to arrive, as this intense burst will fry them."

      If you use the same logic, not observing God interacting with the world does not imply that God does not exist.

      So many of the same arguments apply to both proving the existence/nonexistence of God and proving the existence/nonexistence of extraterrestrials.

      The difference is that "God," as generally defined by believers, is a being who specifically does interact with His creation. There is not (and probably will never be) any evidence either way on the hypothesis of a "watchmaker" who set the universe in motion and then left it alone, but that's not the God people pray to, either. If you believe in the power of prayer, or in the Bible as a moral rulebook, or any of the million and one other things which believers are constantly pushing, you have to believe in a God who should have left evidence of His active involvement all over the place, and yet has mysteriously failed to do so. There are people who believe in active involvement in human affairs by aliens too, of course, but they're a fringe minority rather than being in the mainstream of those who speculate on the possibility of extraterrestrial life.

      Your scale is a bit off.

          I'll make some assumptions for you. :)

          You are an average male, with a size 10.5 shoe, and you have two feet.

          Your yard is 1 acre, with no other objects obstructing it.

          We are only considering a single plane for both your yard, and our solar system.

          The size of your foot equals the size of the earth (cross section at the equator).

          Then....

          If your foot were the size of the earth, the soles of your shoes would have had contact with 0.205381533% of the area of the Earth's orbit around the sun.

          I guess you're just about right then. We like to think we know what's in space around us. As has been proven by recent near misses with asteroids, we are not necessarily aware of rocks the size of a city before they are *very* close to us, or in some instances have just missed us.

          There could be a small intelligent alien species in a small object say a spacecraft or natural body that we have passed off as "just a rock", somewhere between us and our sun, who do not meet the criteria for living on earth, and we wouldn't have ever known it existed.

          We like to standardize "life" on the terms we know. Any advanced life will be roughly 1.5 meters tall, weighing roughly 72.5 kilograms, biped form, which breaths a nitrogen/oxygen mixture. That makes a lot of assumptions, including the idea that it would breathe.

          It could be plausible that an alien species travels in a FTL space craft which is no larger than a mosquito. If it used Star Trek based warp technology, the resulting emissions if it slowed to "impulse" several planets away wouldn't even register as a change in background radiation.

          But, we are humans, and we know everything.

          I just hope that when we are visited, they do breathe oxygen, eat compatible foods, are tall enough so I can stand up in their ship, and they understand when I say "Thank goodness you've arrived, I've been waiting for years to get off this rock. Lets get out of here before the others try to kill you."
