Not at all. Galileo witnessed the revolution of the earth around the sun first-hand. Much of science is built upon first-hand observation. In fact, it really doesn't have anything else to go on. Science, by definition, entails first-hand human observation and reporting.
Really? Where did he stand to do that? Mars?
Much of science is built upon first-hand observation. In fact, it really doesn't have anything else to go on.
Well now, what do you mean, exactly, by first hand observation? Is it first hand observation when I record a stellar event that happened 200 million years ago using gravitational lensing and tacking into an array of photogate amplifiers into an image cleanup program?
Is it first hand observation when I use a scientific oscilloscope to characterize a signal that only lasts for a few nanoseconds?
Science, by definition, entails first-hand human observation and reporting.
As you are defining it, no it doesn't. You cannot reasonably assert definitions of science most scientists would consider childishly silly.
Really? Galileo had a spaceship that allowed him to travel into space and actually observe this? Nobody has actually directly observed the motion of the earth around the sun. It is inferred from other observations, just as most theories and laws in science are.
