Robo should google dark energy but it appears flame trolling is his preference. Cosmology is my 50 year hobby after I ditched religion.
Aereodynamics is robo's hobby and he's pretty good at it.

(Sounds like Elizabeth Homes has some competition for sounding deep and has a prayer of knowing what they're talking about).

Meanwhile, back off planet Earth but in the realm of reality:

JWST starts to unfurl

EBarnacle 'dark energy' is something entirely different regarding accelerating expansion forces as you know. That more volumetric space is being produced is quite a mystery to be sure. The possible dark balancing act going on is a mind blower. We wouldn't want to stretch the universe to its tearing point would we? Some say the entire universe will have to drop to a lower energy state which will be like a big rip. They claim it is inevitable.

C'est la guerre.

The dark matter sweepstakes invites your guess. The winner gets dark matter money.
My guess was non baryonic quarks assembled into strange 1/2 spin hadrons in the technicolor range beyond the 100 hadrons we know (which makes their name absurd since they are invisible) and should be called Donuel-Bose condensates.

Simply put; it is the energy state condensate of the left over energy junk from the annihilation of matter and anti matter. :*)

Perhaps we will find out what dark matter/energy actually is.

When the James Webb search begins it will be looking at a 3 full moon wide patch of sky and measure dark matter gravity in thousands of galaxies. We think we have seen a couple distant galaxies that have no dark matter. We don't know what that means but dark matter may have evolved just as luminous matter has evolved and changed. We can't look back to a young 2 billion year old universe since gas blocked light until it reionized and became transparent but we will see as far back in time as possible. Later planetary searches will be done.
Finding the unexpected or 'unsearched for' is also a possibility.

The next steps will be just as hair-raising as the buildup to the launch:

As you all know, the James Webb Telescope 'package' was launched successfully from French Guiana this morning. A few facts:

The launch site was selected because it's closer to the Equator than Continental U.S. launch sites. This gives the rocket a small but palpable boost to trajectory due to the rotation of the Earth. Which saves fuel.

This is a space project as finely detailed as it is ambitious. Which is Very Very.

I got a thrill from hearing so much French in the background and foreground, right down to the ten count.

The telescope package is now in a phase where it is relatively slowly proceeding to its general area of operation, which will be around the L2 (Lagrange Point 2) area of space a million miles from Earth in a solar orbit which is maintained in sync with Earth, kept there primarily by Earth's gravitation and secondarily by small expenditures of thrust from the fuel aboard.

The mission is known to be limited because of fuel expenditure. It is planned to be useful for ten years. Due to the fuel requirement, it is not likely to last much longer, as opposed to the luck of the Mars rovers, several of which have lasted years longer than their design life.

This telescope is all about heat, particularly separating the detection apparatus from any. It's kind of like when telescopes on Earth are located away from nighttime light sources. Their function is to detect and record starlight. In the case of the JWTS the purpose is to detect and record heat signatures. So the umbrella part is to isolate the hardware for this from the sun, the earth, and the support apparatus in the rest of the package.

There are other unknowns- the effect of micrometeoroids on the structure and of course the science to be done. I understand that over the years of design and planning the astronomers of the world have distributed every minute of anticipated observation.

It's a totally amazing telescope, but it is being assembled into the rocket that will launch it in a way that it can eventually unfurl, like an umbrella. Umbrellas are finicky, and they are trying to design this telescope to avoid some of the pitfalls that plague umbrellas in motion.

The launch date has been set, but it is still changing, most recently due to the weather in French Guiana, where it is presently scheduled to rocket off planet on Christmas morning.

Briefly, the James Webb Space Telescope is an ambitious plan to site an infrared detector with associated recent tech components at Lagrange point (L2) on the outside of Earth's solar orbit. It will take up to a month to get into position and due to the complexity of the craft and its manifold parts, it will be self-assembling over the next six months.

Step one, getting this very complex and valuable equipment launched, is currently set for 7:20 EST 25 December, but consult the website for updates.

You can find their website, which appears to be very well organized with background and latest schedule updates at: James Webb Space Telescope website
