Since it seems you can't have one without the other, maybe time and space are the same thing, constantly being created, ticking, and expanding, insofar as we the observers can see.
For over 100 years we've regarded space and time as facets of the same thing - four dimensional spacetime.
Our established theories pretty much assume that space and time are not, in any fundamental way, different - and those theories work pretty darned well on the large scale.
However, on the miniscule scale, space and time may be completely different kinds of things.
Watch this space (if you've time!).
Einstein called it space-time. It seems they are inextricably linked through energy and if Erik Verlinde is right, at some deep level, ultimately entropy.
Who knows? We can postulate, but it would I image take extraordinary ability in maths to prove this.
I've downloaded Verlinde's paper on emergent gravity. Seems you need Newtons constant of Gravity and the Cosmological constant to calculate it. Dark matter is unecessary. But way over my head.
This "Particle Fever" film was EXCELLENT:

I was on the edge of my seat. I made a lot of notes, but I won't bore you with them. A 115 GeV Higgs would have suggested supersymettry and a zoo of new particles.. A 140GeV Higgs would have said multiverse and no more particles. Well, you know what happened.

The mathematics is so complex that anyone who comes up with a new equation or solution immediately gets it named after them!
One thing it pointed out was they were running FOUR experiments all at the same time. I only remember two, and as I recall (I won't watch the following two-hour or whatever thing just to verify this) the results of only two experiments were announced. What were the results of the other two?
Around 50:40 is the announcement of the ATLAS experiment (also shown in short form in "Particle Fever"), showing the slides using that scandalous Comic Sans font (alson seen in "Particle Fever"), in this announcement. It's long, and all the good parts are excerpted in the documentary anyway:

I took some notes. 4 detectors at CERN.
ATLAS and CMS (Compact Muon Solenoid) were tuned to 126. GeV Higgs detection. CMS found it to 4.5 Sigma. ATLAS to 5 Sigma.
LHCb is an antimatter detector, hence its focus on B-Mesons. ALICE is a lead ion collision detector. CERN runs protons 11 months a year, and Lead ions for 1 month.
Other notable finds at CERN to date:
Bottomonium (quark and antiquark) neutral meson.
Strange Baryon, resembling proton.
Rare B-Meson to muon decay.
Pentaquark and tetraquark.
The theorists seem sure now there must be more particles to come. Perhaps W' (or W Prime) and Z' (Z Prime) bosons. W′ and Z′ bosons - Wikipedia
If there are ‘lots’ of additional particles out there, it’s going to call the standard model into question. Maybe this thing is like an onion. The higher the energies, the more you find.
Or maybe, they are just manifestations of high energy and in a way, they are actually creating this stuff.

ALICE is 28 years old next month.
Smokie lived next door to Alice for 24 years! 😀

Ah, Smokie 1977. Lurex shirts, long hair, bell bottom jeans and loons. Though I preferred white cheesecloth shirts and black pinstripe waistcoat as more Rock n' Roll. Francis Rossi. 😱
Everybody knows the Standard Model is either broken or incomplete. Fixes might be W' and Z' Bosons. The Tevatron has failed to find them below 850 GeV, which is a huge mass. But who knows what lies above?

I rather like that extended Standard Model. Perhaps we need more Bosons! 😀
Bit vague on Leptoquarks or why I want one:
Has a new particle called a 'leptoquark' been spotted at CERN? – Physics World
But exciting times.

What we need is hard evidence of dark matter. Interesting how an ingredient making up 95% of the universe has gone undetected yet the so called smallest particle's discovery is celebrated. Which came first, the chicken or the egg? For that matter,🙂, which is the chicken?
Or I should say, which is the egg?

Let's put this "huge mass" of the W and Z bosons into perspective.
A boson is one of those virtual particles we talked about earlier in the thread. The exchange of virtual particles is used in particle physics to explain the force between interacting particles such as protons. Virtual particles are created from borrowed energy, which is allowed for a short time by Heisenberg's Uncertainty Principle.
The bigger the mass of a virtual particle, the smaller its 'force carrying' range. This means that short range interactions, like the 'weak' force, require massive virtual particles. The massive virtual particles involved in the weak interaction are the W and Z bosons, and their mass is 100 times that of a proton.

If you are referring to the Higgs boson, Pete, then it is not the "smallest" particle.
The Higgs boson is around 130 times more massive than a proton.
