Er, but people had been flying in balloons for a hundred years?No, it was "proven" by experts that birds represented the largest things that could ever fly. Anything larger was just science fiction.
You said all this. And I said that in 1888 the Montgolfiers had flown in a balloon over a hundred years previously. So what this guy said was obviously rubbish. He was a natural history professor, not an engineer. Any engineer even then would have told you that powered flight needed an adequate engine, and the three or four hundred pounds weight limit was popscience rubbish.Put these three indisputable facts together:
One: There is a low limit of weight, certainly not much beyond 50 pounds, beyond which it is impossible for an animal to fly. Nature has reached this limit, and with her utmost effort has failed to pass it.
Two: The animal machine is far more effective than any we can hope to make.; therefore the limit of the weight of a successful flying machine can not be more than fifty pounds.
Three: The weight of any machine constructed for flying, including fuel and engineer, cannot be less than three or four hundred pounds.
Is it not demonstrated that a true flying machine, self-raising, self-sustaining, self-propelling, is physically impossible?
-Joseph Le Conte, Professor of Natural History at the University of California, Popular Science Monthly, November 1888.
Where are you getting this stuff from? Popscience magazines? The Montgolfiers flew in a balloon in 1783.Not back in the 1850's. Both were widely understood to be impossible.
They aren't moving through time, and nor are we. Read the OP.And we have GPS satellites that are moving through time at a different rate than we are.
Birds fly, and your argument is specious. Especially since you could use it to peddle perpetual motion and raising the dead or any other nonsense you like. Again, read the OP to understand why time travel is science fiction. And always will be.And a true flying machine, self-raising, self-sustaining, self-propelling, is physically impossible. At least until it wasn't.
