if they are looking for cracks- they should look at uranus

Matter can possess energy. Energy doesn’t exist outside of matter. The models are wrong, since they do not represent reality.

You can discard pure energy along with dark matter. (Maybe they are strings of consciousness in a non-deterministic space-time-matter continuum with a negative field flow of dilithium crystals).

Cracks in the universe?

Nothing a couple of buckets of astronomic cement can’t fix...

“Energy doesn’t exist outside of matter.”

Arguably, matter doesn’t exist outside of energy, either. Lest you say that you can “see” matter, try doing that without an energetic interaction.

Between string theory and quantum science, God is everywhere appearing.

Dr. Who can fix that in a season.

Actually, matter does not exist outside of time.

“Energy doesn’t exist outside of matter.”

Energy does not necessitate matter. Matter is an expression of energy in time.

Now that Doctor Who has become a woman, it will take forever and never be satisfied ...

Not incorrect. Matter and time are linked. Time is just a physical property, as is mass. You just cannot conceive being outside of time, and frankly neither can I.

“You just cannot conceive being outside of time, and frankly neither can I.”

Actually even conceiving of *conceiving* outside of time would be quite a trick. It’s all so very complicated. To misquote Walter Scott: “Oh what a tangled web we weave when at first we start to conceive.”

A pulsar timing array is a gravitational wave detector the size of the galaxy. Pulsars are spinning neutron stars (collapsed cores of exploded stars) emitting intense beams of light that appear to blink on and off with a precision rivalling atomic clocks. The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) has been obsessively timing a few dozen pulsars for a decade.

Any deviation from the norm could indicate a passing gravitational wave has stretched or squeezed the spacetime between us and the pulsar – causing a slight lag, or advance, in the timing.

“We’re about to open a new window on gravitational waves at low frequencies,” says Siemens, who is also director of NANOGrav. To keep tabs on pulsars across the whole sky, NANOGrav is linked with two other pulsar timing arrays, one using radio telescopes across Europe, and the other based at the Parkes Observatory, in New South Wales.

So far the searches have drawn a blank, as Siemens and Olum announced last September.

“In physics, when you don’t find something it’s not a failure,” Olum says. “It’s a success of a different kind, because it tells us something new about the universe.” The no-show of cosmic strings at certain energies can already be used to rule out some theories of supersymmetry.

...

Well, I learned something new today.

Even when other people don’t, and simply crack jokes, it bumps the thread.

I think string theory will end up having applications outside of physics even if it tells nothing about reality.

Since matter IS energy, what you are saying
is something like, “Ice cannot exist without water.”
How profound.
