Art Hobson claims " There are no particles, only fields". If this is true, does that mean nothing physical really exists?

Perhaps he's right, but if so then wouldn't fields constitute physical existence? This seems more like philosophy though.

Maybe. I can feel a magnetic field. At least it's effects. Does that mean it is physical?

I would say fields are physical, they are produced by bosons.

Another doozy you have come up with here.

Hobson is certainly on the right path when he condemns the ills of today's society as being a carry-over from the dark ages. We are creatures of habit and old habits die hard (especially religion).

I think that without going into quantum physics we have learned that even a block of iron is not solid, it is made up of particles surrounded by "force fields" (excuse my terminology). When we go down to the smallest particle, being an atom, we find the same makeup, a neutron with electrons spinning around it.

So then, along comes quantum physics, which offers some exciting possibilities but I think scientists are not quite in agreement about the ground rules yet, let alone making any earth-shattering discoveries or inventions.

I think Hobson's main thrust is that things physically exist but we can now look at things in terms of their properties and think outside the realms of man-made references, i.e., time, length and depth.

So far as what humans need to know is what we have defined as tangible and measurable within the extent of what our senses detect.

According to the best theory we have today as to the origin of this generation of the universe, it was some 14 billion years ago, that an immense explosion, known as the Big Bang, spewed out massive amounts of liquid like electromagnetic energy in the trillions and trillions of degrees, creating a rapidly expanding universe.

In the beginning, there was the "BIG BANG" which spatially separated the infinitely dense, infinitely hot, infinitesimally small singularity, which event spewed out a liquid like soup of electromagnetic energy in the trillions of degrees, the quantum of that liquid like electromagnetic energy was wave particles, which are not particles at all, as they have zero mass and no electric charge, but they do carry angular and linear momentum, and it was from the quantum of that electromagnetic energy that the earth and all the heavenly bodies would be created.

And although, all that the earth was created from, was already there in the beginning, the earth at that time had neither shape, which meant it was formless, nor mass=void, and no suns had yet come into existence to light up the darkness of the expanding space.

One would expect, that those so-called wave particles, which are the quantum of the liquid like electromagnetic energy, would have continued to expand further and further away from each other in the expansion of the universal building material.

But with the angular momentum of those waves, they collided with each other in nuclear fusion in the creation of the first basic molecules. As the universal temperature dropped to some billions of degrees, the dark energy which was the expansion"s acceleration force, began to form into dark matter, hydrogen and helium, with trace quantities of lithium, beryllium, and boron.

As the universe expanded and cooled, more hydrogen molecules were formed, and from these, after some thirty million years of attraction, came the formation of the first gigantic stars, from which the galaxies would later be created."

And God said, "Let there be light." Which was not the light of our sun within this minor solar system, which solar system would not be created for some nine billion years after the creation of those first massive stars that lit up the darkness of the bottomless pit.

Those first generation stars, from which the galaxies would later be created and which would have been bursting into life and light over an unknown period of time, would have been thousands upon thousands of times as massive as our Sun and millions of times as bright, but each one burned for only a few million years before meeting a violent end, when they exploded out in a brilliant flash before collapsing in upon themselves creating the massive centrally condensed systems called "Black Holes," in which the greater percentage of their mass was trapped, while the great nebular of heavy elements that were created within those massive nuclear reactors and exploded out, was anchored in space around those black holes.
