Given an added dimension,
spacetime with gravity emerges from the physics described by quantum field theory on its boundary.
A spacetime with a well defined classical thermodynamic appears after inflation heats the universe (and its own energy disappears)-- particles, temperatures and pressures.

Further, such an assumption, Whitehead urges, dispenses
with the necesslty to believe that the constancy of the velocity of light is pertinent to spatio - temporal structure, for that structure is predetermined only by the existence in nature of interrelated
spacetime frames (CN 193).6
This process model of divine
spacetime, projected from Whitehead's theory of interpoints and his critique of the Newtonian fallacy of «simple location,» slips into the logical difficulty
with which process theology has accused traditional theism: It is always possible to ask whether any proposed empirical signs are signs of God, and it is never possible to provide empirical evidence
with which to answer the question (1:42).
Rather than conclude skeptically, however, that process theism is an equally nonsensical alternative to traditional theism, this analysis of the interpoint theory discloses that the logical criteria for verifying God's location in
spacetime have collapsed
with the advent of relativity physics.
He doesn't deal
with spacetime.
@fred, I agree
with you 100 % about the origin being outside our 3d
spacetime.
The Advanced Laser Interferometer Gravitational - Wave Observatory's detection of
spacetime ripples from two merging black holes on December 26, 2015, indicated that one black hole was spinning like a tilted top as it orbited
with its companion (SN: 7/9/16, p. 8).
Two black holes stirred up the
spacetime wiggles, orbiting one another and spiraling inward until they fused into one jumbo black hole
with a mass about 49 times that of the sun.
These shells would be connected by a wormhole, so Alice and Bob could jump in (they would have to «merge themselves
with the matter forming the shells») and meet «in some place outside ordinary
spacetime.»
There appeared no way to get a spacecraft to slow down enough to glide into Mars» gravitational
spacetime depression because the «bowl,» not that deep to begin
with, was itself a too - rapidly moving target.
With the Aug. 14 detection of
spacetime ripples, scientists were able to home in on the location of gravitational wave flinging black holes more precisely than ever before, illustrated in lime green on a map of the sky.
In the case of universes
with a positive cosmological constant, semi-classical physics, and in particular an idea called the holographic principle [which holds that the maximum entropy of a region of
spacetime is proportional to its area, as opposed to its volume], is telling us that those universes have a finite entropy.
As Earth drags
spacetime, it drags each sphere's spin axis
with it.
Also in December, Joe's latest article, «Kantowski - Sachs
spacetime in loop quantum cosmology: bounds on expansion and shear scalars and the viability of quantization prescriptions» — written
with Singh — appeared in the journal Classical and Quantum Gravity.
Tracked and timed by radio telescopes, rapidly spinning pulsars can themselves be transformed into galaxy - spanning detectors sensitive to
spacetime ripples
with wavelengths measured in light - years.
By cross-correlating the arrival times of all the different pulses to nanosecond precision across decades, astronomers hope to detect gravitational waves
with wavelengths measured in light - months and light - years as their passing periodic ripples distort
spacetime around Earth.
Four times in the past 2 years, physicists working
with mammoth gravitational - wave detectors have sensed something go bump in the night, sending invisible ripples through
spacetime.
Since wormholes are contortions of
spacetime geometry — described by Einstein's gravitational equations — identifying them
with quantum entanglement would forge a link between gravity and quantum mechanics.
The team, once their film work was done, carried out a number of research simulations
with Thorne, studying how the swirling
spacetime distorted star fields behind the black hole (above).
(Gravity waves, common atmospheric ripples on Earth that result from air trying to regain its vertical balance, should not be confused
with gravitational waves, cosmological ripples in
spacetime.)
To make predictions from the 10 - or 11 - dimensional string / M theories, it is necessary to project them onto a world
with four
spacetime dimensions, and some resulting descriptions have had phenomenological successes.
And if a black hole rotates, as would be the case for a hole that forms from the collapse of a spinning star, it drags
spacetime along
with it, a phenomenon known as frame dragging.
Now this comes from a, this piece of it comes from a 2003 paper by a planetary scientist named Jack Wisdom at the Massachusetts Institute of Technology; and what he discovered is that you can move, as you [were describing] through curved space by moving, [let's] say, your arms and legs, or if you're an alien as it is described in the article, a tripod alien — just for the simplicity of demonstrating how the movements are
with, sort of, heavy feet and a ball at the end of the tail that helped to move the [weight] around, just to make it kind of simple to look through — you can move through curved
spacetime without pushing against anything, and this is the key here.
The absence of a singularity at the start of
spacetime opens up the possibility that vestiges of a previous contraction phase may have withstood the phase change and may still be
with us in the ongoing expansion of the Universe,» Neves said.
Much more recently, the math describing quantum error correction has turned up in a completely unexpected context — efforts to understand the nature of
spacetime by uniting gravity
with quantum mechanics.
Calculations showed that in this model, particles that differ in terms of energy interact
with quantum
spacetime somewhat differently — much as photons of different energies interact
with a prism somewhat differently.
We start
with the fuzzy world of quantum geometry, where it is even difficult to say what is time and what is space, yet the phenomena occurring in our cosmological model still look as if everything was happening in ordinary
spacetime!
Their calculations show that there is indeed a critical temperature at which an empty, flat
spacetime turns into an expanding universe
with mass.
The equation shows that
spacetime geometry equals mass - energy density when adjusted
with the proper units and numerical constants.
A decade earlier, his special theory of relativity had merged matter
with energy while implying the unity of space and time (soon to be christened as
spacetime).
UC Berkeley's Peter Hintz and his colleagues found that a region of
spacetime, denoted by a question mark, can not be predicted from the initial data in a universe
with accelerating expansion, like our own.
Also, astronomers familiar
with the signal are considering the possibility of a microlensing event — a distant radio source may have been momentarily amplified by HD164595 through the warping of
spacetime, creating a cosmic lens, making the radio signal look like a suspect radio burst.
The first direct detection of gravitational waves occurred in mid-September 2015 (but announced February 11, 2016)
with twin LIGO detectors in Hanford, WA and Livingston, LA (both USA) when ripples of
spacetime from the last fraction of a second of the merger of two black holes
with masses 29 and 36 solar masses combined to form a 62 - solar mass black hole
with 3 solar masses of energy radiated away as gravitational waves in that last fraction of a second.
But as we coexist
with this shadow universe in the same
spacetime — no extra dimensions or multiple universes required — there is one signal that could be transferred.
