Einstein's Theory Was Right: General Relativity Confirmed

Score one more for Einstein. A new study has confirmed his theory of general relativity works on extremely large scales.

The study was one of the first rigorous tests of this theory of gravity beyond our solar system. The research found that even over vast scales of galaxies and clusters of galaxies, the equations of general relativity predict the way that mass pulls on other mass in the universe.

The new work also helps rule out a competing theory of gravity that seeks to do away with the need for bizarre concepts like dark matter and dark energy that have irked some scientists. This research indicates those pesky ideas may be here to stay.

    • GR treats a curved space around our planet, at least, as geometry. It is a direct outgrowth of Bohr's atomic model of angular momentum.

      Putting math for curves with angular momentum gives a geometric picture where an orbit is defined by travel in a straight line but around a planet through curved space.

      However, like most of physics, describing anything in fallacious abstracts, regardless of how well the math may be useful as tool, obscures a real understanding and becomes a barrier to opening the intellectual power of the body of researchers.

      Physicists are always looking for a math that will bring a useful math tool and personal recognition based on the current technical medium - when most of them simply never look at the reality to which math has been touted to describe.

      Math is their reality.

      But math is not reality. It's doodles. Not anything, at all more than doodles.

      Of itself, it's marvelous - and has been of great use and will continue so - but somewhere in the educational process, people should be informed to pull their heads out of the sand and open their eyes. Think with their smellers a little bit.

      That's what the great minds do - they fool the 'academy' by calling it "thought experiments" - and then pull a math out of the air to describe it.

      But everyone could do that - if someone told them so.

      Math isn't just doodles, its logic! Curved space-time doesn't just explains the curved path around massive objects, it also explains why objects without mass (i.e. light) are also affected by gravity, and the perceived time delay of light traveling through gravity.

      Or can you come up with your own "thought experiment" to explain these things, since "everyone could do that"?

      That's not the point. Thought experiments ARE what allows people to create new understandings.
      Concepts can be derived by math - but the process has failed so far by the string people, for one.

      They have made great math. It's a been a time of new math exploration.

      I have a friend I call Mr No, or Dr No. If it isn't in math - it does not exist for him. He will not entertain it.

      Math helps enclose most of these guys in blanket - they are tunnel-visioned and not bothering with any view other than a math equation.

      First off, math is fine but it is to be a tool when real numbers are used. And number values are adulterated by constants. It becomes a slight of hand - where numbers are abstracts and faked into giving or validating a useful plan.

      By itself, math can be wonderful. Equations can be wonderful. In the real world, it's more like a card trick. And as soon as people hold on to it, it's the monkey trap - it keeps them from seeing - and thinking. And keeps them saying "No".

      For instance - coordinate systems. xyz - you can rotate your coordinates - you can have two coordinate systems and account rates of acceleration, etc.

      However, there are no such dimensions in the real world. No left and right or up and down - and no imaginary lines floating around out there.
      There are no such.

      All of physics just goes right along with the first casual mention of three dimensions from third grade. ZERO thought after being told how to think.

      Mathematically the speed of light could be considered a dimension -

      Regardless, as soon as we're poking around with scribbles and abstracts, it becomes a shaky world.

      And people just want to have someone else tell them how to think and how important they are for having an idea to quote. -Most people can't even think about how they are perceived or what someone else thinks of them, - let alone new perspective.

      Very few are thinking. Really think.

      They were given one castle of sand and told to keep it up no matter what the waves do.

      Are you in the physics community?
