The method is still the same. Except we claim to use "satellites" now instead of land based instruments, which really seems like a waste of energy and money.
If you're putting satellites in quotations because you think they are fake, then you are wrong, because if you go outside on a clear night with a pair of binoculars, you can see the ISS moving around the sky every 90 minutes. If we can build that in space, then we can definitely put satellites with various different types of equipment
As advanced as you think we've become in 2000 years, I'm just trying to let you take into perspective how germ theory didn't come around until the 19th century.
Thats because they had no way to detect and find bacteria and viruses until someone could develop a microscope powerful enough to see them. By the way, aa ancient greek scientist, whose name I cant remember (sorry), had proposed the idea that illnesses could be caused by tiny little things, bacteria, but he had no way to prove it, and people ridiculed him, because it was like saying ants can kill elephants.
There was a massive period of human existence where the Catholic Church controlled every bit of knowledge and education available, that happened in those 2000 years. What it appears to me, is that "Science" is basically trying to take the place of the Church, in keeping people in the dark as much as possible.
During that period, the church controlled the knowledge because it wanted power, and the first thing you do to keep power is to not let your people read, and they were pretty good at that. Science is the opposite of what the church was doing, bringing us into the light by being able to prove things that most poeple used faith to explain. Denying science is just ignorant.
With black holes, dark matter, etc its all slight of hand. NASA tells us that hey gravity works after all, we have a satellite 1 million miles from Earth, but it is nothing more than a display of authority. "They" take the "knowledge" and horde it while giving us this dog and pony show.
And like everyone on this forum who says that it is all fake, you have no evidence to support it, while there is evidence that we've detected of black holes through gravitational lensing, and dark matter is still a theory, one which fills in the gaps that physicists couldn't explain, that's why people generally accept it as true, but the existence of it has not yet been confirmed as far as I'm aware.
So you might think we've truly advanced, but have we really? It is human nature to feel that we are at a pinnacle when we could be anywhere along the hill, for all we know. There is still so much more to learn about life itself, Mankind's true origins, but instead we waste our time measuring space, with ancient techniques mangled into abomination with abstract mathematics.
While you're right that it is human nature to think like that, the scientists and engineers that work on this realize that we have not even come close to being as intelligent about the universe as we can be, that's why we have new technology coming out every year, because they know they can do better and they try to do it.
As long as we trust people supposedly smarter than us, wiser than us to do the thinking for us human consciousness will never evolve, instead we are stuck in this modern day version of the dark ages where ignorance is king.
Ignorance is king simply because of people like you, who choose to ignore the science presented to them and go on believing things that are mere speculations. That, or they simply do not understand what they hear because it is too complex for them, and instead of trying to understand it, they ignore it and think it's bad because there's big words that they dont know what they mean, which is what you see with those idiots who choose not to vaccinate their kids.
Also, when you post a link with information, my advice would be to get that information from a reputable source, like from a college, or a respected organization, even if the info is correct, so as to minimize chance of someone trying to refute what you say by stating that your source is not reliable.
