Unfortunately those are most loudest people. Those who actually know something rarely speak or they speak not in mainstream.
Well that depends what you mean by mainstream. You, personally, can read the latest scientific literature in physics, astrophysics, and so on. It's open to you, you don't have to get your understanding through the mainstream media.
Just go here
. If you're interested about astrophysics specifically go here
Everything in here is poiting a direction or gives a hint. There still are things that affect greatly what we know about laws of physics and can even bend them. We still don't know exactly how would twin sun's make affect on a habitable planet. Would it affect anything in physics or just gravity.
Gravity *is* physics. An understanding of how gravity works on all spatial and temporal scales is one of the primary goals of modern physics.
We need to go in space to confirm these.
Well, not necessarily. Much of this stuff can be tested from the ground.
Unless something has been tested and its theory, its not "viable" until its tested. After testing we can say: That's how it works.
Well, sure but the "laws of physics" as you seem to want to term them simplisitcally that we currently have are those that have already survived many, many observational tests.
Huge but still not enough so people could be arrogant and disregard changes of far greater being... something what well can be considered... deity like being in this universe.
"Arrogant" is a very leading choice of words. Or rather, that choice of words suggests that a conclusion has already been reached - and a line swallowed about certain questions being unaskable.
People use physics and science as well their own personal advantage if it fits their view of world, just like some people use religion for their own selfish purpouses. No thing on here is unaffected by human greed and will for power.
Yes, there's politics in science. There's politics in human endeavour. The western christian church has a ~1000 year lead in politics and population management than modern western science though.
Humanity cannot figure out how universe works, until it travels into the stars. Until then... everything is... we'll... Theory.
No, this isn't true. Most observations of value will be remote. We may benefit from a more local view for many things, but it's not a deal breaker for good chunk of modern physics. It's certainly not the difference between "theory" and "law".
