[@Danny_6Handford]

So far, it appears that the universe started as something tiny and started to expand to what we can observe and detect today. It also appears that anything we can observe or detect is made from extremely tiny particles which interact and combine with each other based on some fundamental predetermined rules. We also have identified quit a few of these extremely tiny particles and have identified quit a few of the rules these particles follow to interact and combine. Perhaps most of the particles and most of the rules but there may be more and, we also figured out that anything that we can observe or detect is made from the same basic stuff and we named this stuff energy. We know this because we have figured out how to calculate a value or quantity of energy for anything that we can observe or detect. It also appears that after the universe started to expand, no more energy was added or removed as it continues to expand. We do not know what the rules were that determined the amount of energy in the universe nor what caused the energy in the universe to start expanding. The rules for how energy expands, transforms, interacts and combines cause energy to cycle from concentrated to diluted states. Although the cycles can be repeated almost to an infinite number of times, there will be a time when they stop because as the cycles keep repeating, the total amount of energy in the universe keeps becoming more and more diluted. We call this rule entropy. At some point in time, all the energy will become so diluted that it will not be able to cycle back into more concentrated states and we think this is when the universe ends. We still do not know the rules before the universe started to expand and we still do not know the rules after the universe will end and there are probably still many rules that we do not know as the energy in the universe continues to expand and cycle back and forth from concentrated to diluted states.

[@CPHSDC]

What if the universe is rotatating, revolving around a center as it expands? We would see the same galaxies at different times in their lives. As we focused backward in time, the same objects would be found in different parts of the sky. That would mean the universe is less massive than we suppose. Your Welcome.

[@Danny_6Handford]

@@CPHSDC It’s always fun, entertaining and sometimes interesting to play the “what if games”. Sometimes they can help us think about new ideas but until we can find some evidence for the “what ifs” they will remain speculation.

[@CPHSDC]

@@Danny_6Handford I would look at galaxies and quantify, date them, arrange them along vectors in space time and see if any fit together. But I only have a pair of binoculars. ANOTHER WAY of saying what I'm saying is the universe is smaller than we currently construct it and some of what we catalogue are duplicates. Pretty weird. Subtract all that mass.

[@isatousarr7044]

Energy is a fundamental aspect of our universe, influencing everything from the smallest particles to vast cosmic structures. The laws that govern energy, such as the laws of thermodynamics, not only explain how energy flows and transforms but also underline the interconnectedness of all matter and forces. Considering this, how do you think our understanding of energy and its governing laws will evolve as we explore new technologies and delve deeper into the mysteries of the universe?

[@GavinM161]

But history can warn us (if we choose to listen). It can also inspire the future.

[@jakubkusmierczak695]

@@GavinM161 People learn only on failures not from the frontiers of science. Just look in the past (constantly) - wars, colonialism, slavery, tyrany, imperialism, dictatorship, regim, earthquaqes, tsunamis, poverty, famine, death. Science gives new possibilities, wealth, richness of life. We should see bright future in front of us not the dead end behind. Einstein said that we can not solve problems with the same way of thinking that they were created (stuck in the moment and can not get out). It means that we should study something new e.g. science. Science has advantages even over the religion, since religion can give you nothing and takes everything e.g. life, and science can give you everything and takes nothing e.g. life. How history can inspire the future? you are going to be great worrior, hero, crusader, king, mass murder, dictator, knight or saint? The greates threat for us, are we so nothimg to warn. If you look at the history from industrial revolution everything has changed (1700). Even now - blue led light reduces the consumption of coal and green house effect, heat pumps generate energy from air, PV gives you power from sun, WWTP produces methane and clean sewage. Everything is in the future mind not in the old history - but first, you have to create it (the most difficult part with no copying - ethos).

If energy is finite & if it flows from concentrated to dispersed, then both of these depend on a container. So therefore the Universe would be the container & it would have defined edges, right???

[@helicalactual]

the reason the heat doesn't go back to the source is because of the Higgs mechanism. as a result, things got "clumpy" and so, did the wave functions. heat is merely too many wavefunctions in a given tensor.

Is the energy driving the expansion of the Universe self sustaining? Is the expansion a steady one, or is it in waves, or in slow pulses over time? I agree with with Marttihelevirta4149, no one has proved a closed system, or even proved (satisfactorily) a multiverse, of many Universes, or anything else (yet)

[@alangarland8571]

The multiverse idea is generally considered to be speculation, not an actual scientific theory, since there is no possibility of it being tested. The expansion of the known universe is currently thought to have started extremely rapidly as a process called inflation, after which it then continued more slowly and still is doing so. This ongoing expansion requires energy to drive it. It's called 'dark energy' since we don't know what it actually is or where it comes from. There isn't any good reason to think it might be manifested in the form of waves or pulses.

[@leftmono1016]

The rate of expansion is increasing over time.

[@tponto6656]

Love the presentation of information in these videos, but there are such gaps for the newbie like me. At the 10 minute point, yu talk about the need for energy and then bring up the advent of the steam engine but never describe how steam energy powers things... I gather you burn some wood or coal or something that boils water and makes steam to turn a wheel... but I don't really know...would be nice to get more granular so people today could understand all the exact ways that power (electricity) is made...

Technically the sun is going "boom" at every instant since its ignition, only there is so much gravity the matter and energy is all in equilibrium. When the equilibrium is broken that is when stuff like supernova and red giants happen.
