It does not matter what frame you are in.   EVERYTHING is in motion.  Everything ALL the TIME.   It's a pillar of physicality.

Physics, Astronomy & Cosmology / Re: What do we do about the orbiting space junk?

« on: 18/02/2021 00:27:32 »

I would look at it in a different way.....and propose a proof of concept experiment.  We track the big pieces with radar.  I would put a UV or x-ray laser in orbit, and see if we could ionize the junk object, and see what affect it had on it's orbit.    I would not rely on any simulation or opinions.  If that alone doesn't work, a magnetic field can decelerate the charged object. Space robot cowboys.

But even if we could remove the large junk, there is still a great problem, and that is all the "speck" junk.  Perhaps a high powered x-ray emitter, to ionize, flying in a grid search fashion, might charge the specks.

It's a black-out area for measurement.  Much blacker area than the black-out area around Green Bank. And it will allow reception of all frequencies.  No atmospheric filter.  10,000 Hz to 100 MHz or so might be very interesting.  1 to 30 MHz would interest me.  And without that filter, THz would be of great interest to many.  With all the chatter from earth, and earth orbits, blocked out.  We could use almost the whole dark side as a giant ear/eye for unexplored spectrums.  And solar flux studies as well.

Networking is great, for it increases quality and service.    It helps all vendors satisfy all customers.

But all endeavors can be abused.  Powerful networks can limit and ration for price and power.

Physics, Astronomy & Cosmology / Re: What is the cosmic microwave background?

I would not rely on any estimate of cosmos(or even galactic) mass.  All stars spew out isolated free charge continuously.  Think about that......think how long they have been doing that.   We can find no evidence of charge recombination from our sun.  The charge from our sun is still accelerating out past Neptune.  If that charge recombined, we would detect the emission.  Think about all the charge from the sun for eons.  And eons of stars.  There could be a good chance that most of the mass(isolated charge) in the universe, is not under gravitational influence.

And a good chance that there could be much, much more mass than thought.   Naked mass might be different than gravitational mass.

How about this, we believe that high velocity makes it difficult for recombination.  What if a simple pole flip on a particle made a difference?  What if there are certain velocity and density conditions where a high velocity recombination readily occurs with an unknown emission spectrum..........such as CMB.  CMB might be fresh.  A cold spectrum.

Astronomy is an unique science.  When we photograph motion on earth, all the objects are in present time. One time stamp. But a star field is not an image of objects........it's an image of time stamps, with unknown AND different times.  This is unique. We are foreign to this dynamic.  On earth, we have never had need of this way of thinking and understanding.  That does not include recognizing star field patterns with season.  That reasoning when to the gods.

We can not see the present universe or even our present galaxy. The present universe might be dark and scattered.

It's hard to fathom that our galaxy's center could have super nova-ed thousands of years ago.

Compare the number of assumptions that astronomy uses with the number of assumptions that chemistry uses.   Astronomy needs salt to swallow.

Not that there is anything wrong with astronomy.  Like I said, it's unique. A different kind of puzzle.

Modern theory believes that mass and motion can change time.

They also believe that a change in clock tic rate, or a change in frequency is proof of a change in time.

This allows time to vary with motion.  They believe this is the only way to explain light velocity measurements.

Any theory or explanation of CMB must have these underpinnings.

So, if you capture a CMB wave, it would appear very old to us, but for the wave, it thinks it's only milliseconds old.

See what you can do with science?

« on: 30/08/2019 10:26:23 »

Do you know what a jig is?  Have you ever had to assemble a collection of the same objects, over and over?

It gets boring and time consuming to assemble the same thing over and over.   SO...we build a jig.

We will place all the components in the jig......then with one operation.......one lever pull or a crank.....and the object is assembled.

The assembly device is called a jig.

A catalyst is a chemical jig.  It "fits" the components.
