Quantum Physics and the End of Reality by Sabine Hossenfelder and Carlo Rovelli

Hi Aleksandr,

You say 'time acts throughout space' but, IMO, that's not quite the right expression. Energy acts, time applies It is more like labelling ,identifying. lets say you have as far as you can tell a complexly empty volume of space. Nothing to identify it from any other similar volume. Now imagine you can see a dot, which divides into two ,then 4 dots. Now there was a time of 1 dot followed by a time of 2 dots followed by a time of 4 dots, The time pertains to the existence in the space, its distribution and arrangement are useful descriptors. The sequence of the dots gives the 'direction' of the arrow of time.

Hi Georgina You can share "something = that." It is useless to divide zero. There is no past as a place for processes. You can call the past a point only on the abstract axis of measuring the duration of events.

The universe is voluminous. The universe is always in the present. If the present was a line or plane, then in the present there was a part of the Universe and the Universe could travel through time (from one present to another). The IMO Universe creates a process of time movement. Each process determines thermodynamics. Thermodynamics gives the 'direction' of the arrow of time.

Hi Aleksandr,

I agree with you that processes do not occur in the past. Instead of past time realms we have memories, records and artifacts of formerly existing configurations of matter and happenings.

You need to be clear what you mean by 'universe'. You are not referring to what is observed. That being space-time observation products So this is another version, an exiting universe not observed. Be clear what you mean by Present is it the seen content of observations currently produced (general parlance ) or when your unseen universe exists. Does time create thermodynamics or is thermodynamics and other movement processes perceived by us (via our senses) as time passing. I know what I think. Biological processes can act against thermodynamics but still progress in the 'direction' of the arrow of time.

Hi Georgina

Memories, records, artifacts are information. The universe exists independent of our consciousness. Products of consciousness: brain-driven images and activities. The "present" is the period of time in which all processes go: physical, chemical, biological. The movement of time creates thermodynamics. I will post about this on the time podcast.

Biological processes do not act against thermodynamics. absorbed energy (from photons to meat) has more energy than the resulting product. Biological processes implement Newton's 3 law - by opposing the movement of energy, absorb and transform energy. Every Action Gives Rise to Opposition

Back. To quantum physics.

Attention! I don't know English. Google translation. Hobbies are the philosophy of time.

(c) Temperature is related to electromagnetic radiation. Electromagnetic radiation occurs when an electron moves from a high, to a low orbit. Consequently, the temperature of the body is one, with the rotational energy of the electrons of the atom. Let's consider the differences between thermal, kinetic and potential energy of the body. Kinetic and potential energy is a vector. Temperature, a scalar characteristic. Having energy of motion, and not having a vector, allows rotation. Conclusion: temperature is the rotational energy of the electrons and nucleus of the atom. Vector, is transformed into rotation if the vector is "bound" to a point moving slower than the body. Braking, when sliding, creates a rotation of the atoms in the contact area, creating an increase in temperature at the surface. The result: Sliding down an inclined surface, the potential energy of the bar, is transformed into the thermal energy of the contact molecules. The impact creates interatomic interaction and the transformation of kinetic energy, into thermal energy, occurs throughout the body volume.

Hi Aleksandr,

sorry I wasn't precise enough. I meant that biological entities release energy from food intake, so entropy decreases rather than increasing for those systems. Yet the 'direction' of time is the same.

Hi Georgina, Write a letter to mltsv126@maul.ru

Material neuronal structure in which memory is encoded, physical records such as writings and relics , such as pottery shards are existing things-Now.

I'd agree that consciousness does not create existence. Through action of material bodies and machines directed change happens motivated by conscious will. Also consciousness 'stitches together' the products of our senses, giving us each a relative perspective and limited semblance of the external, observer independent, existing actualization.

But quantum physics found the act of human observation changes the outcome of experiment.

Of course it changes the outcome. But only because:
If a human observer views a coin, floating motionless in space, then the outcome of "calling" the coin (either "heads" or "tails") will always depend on which side of the coin the observer chose to view, and whether or not the observer made an error in their decision, as would frequently occur, whenever a coin happened to be viewed, nearly edge-on.

Robert McEachern
The chosen coin toss protocol limits the outcome states that can be obtained. To either exposed flat side rather than any orientation, as might be obtained if the coin was instead tossed into a bowl of partially supportive jelly. The chosen protocol affects the outcome state ; catch, then palm opened to reveal gives an opposite result to catch flip onto back of opposite hand, reveal. When the catch occurs is important as it stops the change of state process that is happening. Schrödinger's cat too the time of observation matters , as it halts the fate of the cat being bound to the radioactive decay, if it hasn't yet occurred.

Robert McEachern
Because I'm still not getting to grips with how this new web site works .I did not see your specification. Isn't that yet another protocol but the coin may be objectively (un-measured) in motion or objectively stationary .We know not which. So the time of result sampling may or may not play a part. It can be any way oriented like the coin in jelly. The sampling protocol needs to specify how to decide the outcome state.

Georgina Woodward
The "sampling protocol" is as follows:

Two astronauts, Alice and Bob, are floating in space, on opposite sides of a coin. Relative to each other, all three entities are motionless. So how do Alice and Bob "decide the outcome state?" What is that state?

Robert McEachern
Accepting the 'state' of a coin to be the flat side of the coin exposed when the 'measurement' is taken: Usually the chosen protocol allows only one of the two possible sides to be seen. In your scenario that is not so. If suitably aligned (you mention on opposite sides of the coin, meaning I think each facing the different exposed faces.) There is not one relative measurement outcome state but two. Pertaining to the two observers. As the characterization of the absolute object is being limited by only considering which of the sides is exposed. Both are individually correct about the state of the coin as seen from their own viewpoint.
You have given a good illustration of why the state of an object is not applicable when there is not a singular, relative viewpoint.

Georgina Woodward

The 'state' of the coin, is not "the flat side of the coin exposed"; that is merely what an observer happens to see. The question is, what is the actual state of the coin itself, independent of any observation, that induces the multiple observers to see, whatever it is that they see?

Robert McEachern
Robert, I think it is partially to do with the language we use. By the state of the coin itself , i think you are referring to the condition of the coin, in which the coin exists. I'll say, imagining it to be real, it is an existing object made of metal, with two flat sides, an edge, an inside, that can be oriented in many ways relative to other objects . It, the coin object, is not any relative perception of it. Relative perceptions are limited observation products. Outcome state refers to the result obtained, which when dealing with coins is usually heads or tails observed. Which isn't the coin itself but more like a score to the red or blue team.

i just want to say something about 3 d cartesian coordinates used for mapping, Necessarily they map what is observed to be, from a re al or imagined viewpoint. i.e. They map observation products from a relative perspective.

Georgina Woodward

Do the "two flat sides" exist simultaneously? Are they, in any sense, diametrically the opposite of each other?

Georgina Woodward

Sounds like the very epitome of a quantum superposition:
"Superposition is the ability of a quantum system to be in multiple states at the same time until it is measured"...

Except for the very inconvenient truth that, in Reality, a coin continues "to be in multiple states at the same time..." even after it has been measured...

If the two astronauts had video cameras mounted on their helmets, transmitting video images to each other, they would both see the entire superposition, continuously, without it ever undergoing "collapse", into just one state or the other...

But how can such coins possibly exist at all? After all, the entire physics world has assured everyone, that superpositions like that, only occur in the quantum realm, not the classical realm.
