Has anyone contributing to this thread made the statement that the climate is not changing?

Love it when it snows
Nothing quiets things down like a nice blanket of snow. The roof is muffled, and the forest too. But I think there may be even more going on. Doesn't snow often here, but every time it sure does seem like the power is cleaner. For sure the listening is better.

Climate are always changing... But is climate changes are only caused by human activity ? Certainly not... Is it a good thing that we unite to be less vulnerable to incoming changes in solar activities, meteorites, comets, and other catastrophes pending ? Yes... Is there some consequences to human activity on earth that we must be conscious of ? Yes... All other controversies are politically motivated, climate is a way too more complex thing to be solved in few words here... Is there solutions? Yes... Nourishment of the world population and education is one of the most important solution, improving the brain power by numbers and education by action... What else to discuss? Nothing, the rest will produce controversies impossible to reduce in a polite intelligent and informed discourse here... Next : audio, snow, music, even cosmology..... :) Perhaps Scriabin? |
Yes the idea of a universe that is finite and unbounded is a bit hard to grasp. Its kind of like this. Look out in any direction, any direction at all, the view is exactly the same. We appear to be right smack dab in the middle of it all. Which we are. Always. Everyone everywhere is right smack dab in the middle. Dudes on some star way over in Andromeda? Yeah those dudes too. We have a hard time drawing this, and its even harder to visualize, I sure never can, but its kind of like this. Mass curves space time. Not a lot. Takes a lot of mass. Even so you have to be pretty close. But Einstein math'd it out and some years later when they observed the orbit of Mercury with great enough precision sure enough, the planet was exactly as much slower as relativistic physics said it should be. So math curves space time. Another way it has been observed to do this is with very distant galaxies. Yeah here ya go https://www.universetoday.com/wp-content/uploads/2014/11/Gravitational-lensing-galaxyApril12_2010.jp... So now notice how the massive galaxy cluster curved space time around it? The light actually travels a straight line. Its the straight line that's curved. Well it only looks curved because of our frame of reference. Hey don't blame me! I didn't make the rules! Just telling it like it is. To the extent of our current understanding anyway. So obviously (its obvious, right?) the whole mass of the whole universe is doing exactly the same thing. Curving space-time. Curving it so much it wraps around on itself like a ball. Only it can only appear that way from outside. Same as the Earth can only appear spherical by leaving the surface and going out into space. Perspective. From here on Earth it appears quite flat. Or at any rate two dimensional. So it is with our finite, unbounded, universe. |
There is a relation between gravity and consciousness and I like Penrose because it is one of the first to guess that... But for sure I dont know if his theory, orchestrated objective reduction, interesting by itself, is right.... Perhaps the elementary fact that loosing consciousness, the body is at the mercy of some relatively " free fall", is a more profound metaphor than we first think of, at face value... :) |
