All red would have turned to blue one way, or blue turned red the other way. Surely if someone is in a time frame that is, say, 40% slower than those around them, they would see things in a very odd way. Time dilation enough to be noticeable would quickly cause severe suntans from the normal light fittings.īut what really struck me, in this dream, was frequency. If an environment has normal time, and is, for example, in daylight, but some person is (near) frozen, the amount of light and heat hitting them, from their point of view, would have enough energy to vaporise them very quickly. The huge issue that occurred to me first was energy - sonic boom type stuff but with heat and light. The SG-1 I am watching now has time dilation in the SGC over a distance of a few floors of the facility. The idea of "stopping time" for everyone in an area apart from the protagonist, or just for one person, is very common in sci-fi. In StarGate Atlantis they had a portal that transitioned through a time dilation (but supposedly protected you from the transition effects). Sometimes (like a Star Trek Voyager) there were people walking in one time frame around a room of others apparently "frozen" (but just really slow). Sometimes (like a Star Trek TNG episode) there were these bubbles of different rates of time. Now, lots of sci-fi has time dilation, for various reasons. My thought was how the human body could possibly cope with passing through some level of time dilation - what gradient would make sense before blood pressure either way is fatal, etc. One that would be a great one for xkcd What If? is what sort of time dilation gradient could a person tolerate? One of the thoughts that then occurred to me is that time dilation must change over a distance, creating a gradient - a rate of change of time over distance. But I'll try explain the weird dream I had the other day.įirstly, time dilation is a thing, the fact that some things (gravity, for example) can mean that in one place time may go at a different rate to somewhere else. Someone will tell me I have this wrong I am sure.
