21 In his James Lectures at Harvard in 1940, he abandoned the term «particulars» for «universals» or «qualities» that, based on the examples he cites, functioned somewhat like Whiteheadian «eternal objects»: that is, ordinary macroscopic objects or experiences are to be conceived as a particular togetherness of these qualia at a given locus in spacetime.22

Ripples in spacetime travel at the speed of light.

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.

So far, they have succeeded in creating a stable four - dimensional spacetime, when viewed at large distances.

And the other really fascinating implication of general relativity is that falling through a vacuum in curved spacetime by stretching and contracting but not at the same rate, if you stretch at one rate and contract at another rate, you can actually slow your descent and behave like a glider even though there is no atmosphere.

The article, which reflects the work developed under the Thematic Project «Physics and geometry of spacetime,» considers the solutions to the general relativity equations that describe the geometry of the cosmos and then proposes the introduction of a «scale factor» that makes the rate at which the Universe is expanding depend not only on time but also on cosmological scale.

In curved spacetimes, when we compare two observers at large separation, we can no longer use the «locally flat» approximation.

But then a little later he looked at his equations anew and realized that they contained a surprise: ripples in the fabric of spacetime that would carry messages across the universe.

He and his colleagues plan an experiment that will attempt to measure how information, matter and spacetime behave at the tiniest of scales — the Planck scale.

Their calculations show that there is indeed a critical temperature at which an empty, flat spacetime turns into an expanding universe with mass.

Such an (entirely theoretical) device would somehow allow an object to change mass and inertia at will, and potentially to travel faster than light by «altering the spacetime metric» around itself.

But Einstein looked at space and time and saw a single dynamic stage — spacetime — on which matter and energy strutted, generating sound and fury, signifying gravity.

Because spacetime is being increasingly pulled apart, much of the distant universe will not affect the black hole at all, since that energy can't travel faster than the speed of light.

«The beauty of COMPAS is that it allows us to combine all of our observations and start piecing together the puzzle of how these black holes merge, sending these ripples in spacetime that we were able to observe at LIGO,» said Simon Stevenson, a Ph.D. candidate at the University of Birmingham and the paper's lead author.

It will not solve the mystery of what goes on inside the black hole, but will at least verify one of the predictions enshrined in current theory: «General Relativity describes gravity as the geometry or curvature of spacetime.
