Morning to you Livinglava: Thanks for the explaination, but if I'm honest, I kinda got a bit lost after the merry-go-round part.........is this stuff theory or has it been proven? I will say this though by way of stating that I will revert back to a globe convert if 'anyone out there' can provide footage of a rocket entering our supposed space, but this has to be 'convincing footage' i.e. no lack of continuity, one-take footage or non-edited footage, from take-off stage right through to the 'all important' entering space (final stage)...........with a guesstimated 17,000+ rockets launched into 'space' then one would imagine this to be a very simple undertaking..............Shalom.
You should not believe anything. Doing so causes you to fear being tricked. As long as you regard all information with only tentative belief, you can more fully contemplate what you read without worrying about being duped.
The only reason for the 'merry-go-round' analogy, as you put it, was to note that planets rotate within solar systems, galaxies rotate, etc. so there is cumulative motion. That was supposed to answer the question about the total cumulative speed of the Earth being high; BUT it was also supposed to help you realize that there is no straight-line path between different rotating systems. That's what Einstein was showing when he started talking in terms of 'geodesics.'
I share you skepticism about space travel. It's not that I believe or disbelieve it, though. I just take the information I get about it tentatively, while continuing to think of reasons why it isn't plausible. One such reason is the ionosphere. Ionized gas is basically flame, so these rockets and re-entry vehicles would have to pass through flame, which they supposedly do by using shielding.
Also, once you get beyond the ionosphere, you are still surrounded by ionized subatomic particles, only the material is sparser, so the density of the flame keeps getting less and less dense as you move farther from any gravity well. This of course discounts solar wind and other density variations in the plasma-space.
But your grand question of whether it is 'just theory or proven?' That is a deep philosophical question that can only be answered by you fully reviewing and critically questioning whether mistakes have been made in the interpretations of observed and experimental data. Rejecting received knowledge from others puts you in the precarious position of Adam and Eve rejecting the warning not to eat the forbidden fruit. Certainly God could have been tricking them while the serpent was revealing the truth to them; that was the outcome they bet their lives on anyway, but then of course they died, as God warned them they would.
I don't relate this Bible story to discourage careful review of received knowledge, which is good, but to also note that it is good to believe tentatively, if only to avoid the worst possible consequences of flouting something that might otherwise enable you to avert problems. But even if you do choose the safe route of tentative belief, you should still never stop questioning and thinking critically in order to, hopefully, uncover deeper and fuller truths.
