Is space-time smooth or chunky? A new study tried to find out.

What is the fundamental nature of reality? Is space-time — the four-dimensional fabric of our universe — ultimately smooth at the tiniest of scales, or something else?

It seems impossible to measure, but with the power of advanced telescopes peering through billions of light-years of distance, researchers are beginning to look down. Deep down.

KEYWORDS: astronomy; einstein; physics; quantum; science; spacetime; stringtheory
Einstein's Theory of General Relativity has the universe smooth at the smallest scales. But quantum mechanics implies a frothy bumpy space-time at smallest scale. I am not sure how this finding relates to the research of some physicists who believe space-time can be quantizied at the smallest scales.

I don’t understand why it is not true that the more one understands creation, the more one sees a creator behind it.

i.e. the more we know, the more we know we don’t know. It’s a fascinating search, though.

I see Science as trying to figure out how it all exists and Religion as trying to figure out why it all exists. The two are completely separate pursuits, though understanding one can often give keys to understanding the other.

Just finished “The Science of God” very interesting read. By Gerald Schroeder

Its both chunky and smooth. It all depends on how far away the perspective is.

In short , one person’s chunk is another person’s smooth.

Space is infinitely malleable.

The ancients of the Yogacharin tradition of India had this all figured out.

If you want to take a crack at it, read here:

From Wiki:

Many theories in physics have mathematical singularities of one kind or another. Equations for these physical theories predict that the ball of mass of some quantity becomes infinite or increases without limit. This is generally a sign for a missing piece in the theory, as in the ultraviolet catastrophe, re-normalization, and instability of a hydrogen atom predicted by the Larmor formula.

Some theories, such as the theory of loop quantum gravity, suggest that singularities may not exist.[8] This is also true for such classical unified field theories as the Einstein–Maxwell–Dirac equations. The idea can be stated in the form that due to quantum gravity effects, there is a minimum distance beyond which the force of gravity no longer continues to increase as the distance between the masses becomes shorter, or alternatively that interpenetrating particle waves mask gravitational effects that would be felt at a distance

Thanks. I need to check that out.

Our conception of time itself is now turning out to be very incoherent and superficial.

Perhaps, from the point of view of eternity, the end of the cosmos is also its source and its temporal beginning.

Perhaps the ultimate flower is also the primal seed from which all sprang.

Perhaps the final result of the cosmical process is the attainment of full cosmical consciousness, and yet what is attained in the end is also, from another point of view, the origin of all things.

So to speak, God, who created all things in the beginning, is himself created by all things in the end.

I’m of the impression that the universe is both infinitely large and infinitely small. And it is made up of nothing.

Youtube is actually really good for showing this:

And the whole thing fits into my view of the God of the bible.

Article says they focused on a cloud 18 billion light years away. IIRC the universe is 13.7 billion years old so I’m wondering how they can see light 18 billion years old...maybe millions instead of billions?

Space expanded at a rate faster than the speed of light (so goes the theory). There isn’t anything to stop Space itself expanding faster than the Speed of Light. This cloud must be on the other side of the expansion from us. (Theoretically).

At Plank scales, it’s chunky. Beyond that it gets smoother and smoother.

Thanks Redcitizen. I'm sure this won't be figured out in a Jif.

Shroedinger's Universe: when you open it, it gets all chunky, but how do we know it stays that way when we stop looking?

And how many theorists can dance on the head of a pin?

The space-time in the red labeled jar is the smooth. The stuff in the blue labeled jar is the chunky.

As long at the universe doesn’t have diverticulitis either can be found. But only the smooth otherwise.

Its swirly, possibly with eddies and sinkholes (warped in toward large masses, blackholes).

You got peanut butter on his Creator.

There is 'beyond'/outside our sensing at least one more spatial variable and perhaps one more temporal variable (which we can infer) in the Universe God has created. Reading the 5th Chptr of Daniel, a being from a greater spacetime coordinate set is physically present in palace party central, albeit only the hand of this real being is in the spacetime coordinate system of the party room. The rest of the being may be surmised to be in a greater coordinate system but reaching 'down' (or back) into the Babylonian palace. Where the hand was physically altering the surface of the wall as it wrote indicates that atleast where the being was in our coordinate system it was physical. So where/when is the realm of the rest of the being?

Xeno’s Paradox strongly suggests that both space and time must be quantized.
