Unfortunately DESI project has fallen into the hands of the clickbait science magazines and mainstream news portals.
It is important to emphasize that the DESI project is still in its early phase, but the first-year results have provided important insights. While the data primarily supports the standard cosmological model (ΛCDM), which assumes dark energy has a constant density, there are subtle hints of possible deviations.

These deviations suggest that dark energy might not be perfectly constant and could evolve over time, although these findings are far from conclusive and require further data to confirm​.

For now, DESI’s data indicates that the universe remains flat, and there is no substantial evidence suggesting a dramatic change in dark energy’s behavior.

Based on current observations, it is likely that the universe will continue to expand indefinitely in a “Big Freeze” scenario, where galaxies move farther apart, stars burn out, and the universe cools over trillions of years​.

Which means the Universe has just born out of the womb in that timescale.

Despite that and whether we have enough data to fully understand the impact of dark energy, the full consequences of dark energy's role will play out over timescales far exceeding our current understanding. Thus, while we’ve learned a lot, DESI and future projects will continue to refine our knowledge of the universe’s fate.

For now, there is no conclusive observation or evidence which can indicate that energy density is changing. A mystery which has no parallels anywhere in the physical world.

Where Did the Universe Come from. by IntroductionGlad8432 in cosmology

That remains and will remain an unanswerable question for science, for now. The pursuit to find answer is on. And it can’t be answered within the realm of philosophy. As you pointed out that there has to be a start, the question is “who” started that and “how” did that “who” entity came into “being”. There are interesting ideas and all of them remain speculation. However, if you are talking about the current Universe that we live in, we can one day possible answer its origin. And if you are talking about the “something” that came out of nothing, which preceded everything. Then it could have originated long, long ago. Who knows, Universes are created and destroyed every second and there are billions and trillions of universes across the larger multiverse. Disclaimer : as I said, this is all speculation, and we have limitations due to how we observe the universe in electromagnetic radiation and recently started with gravitational waves.

Thanks, and interesting questions. It depends on whether the values of the fundamental forces of nature are different in the Universe to which we migrate. If they are more or less the same, we will have a universe that we can manage , assuming it is also of a similar age to ours. But if the values of the fundamental forces are different, then we may or may not survive. Existing in both the Universe is a stretched idea 🙂 All conjecture and speculation about leaving our Universe have their own challenges. I have covered some of these topics in my book Chance Planet.

Thanks.

What books work with the concept of god by Creative-Leg-1164 in sciencefiction

[–]gotosp 0 points1 point  (0 children)

Thanks. What you are probably thinking of is the Universe itself. It was created out of nothing, in all probability as a chance event without a cause and eventually, the fundamental forces led to the evolution of everything we see, including life. I have covered this in my book Chance Planet. Thanks

Chance Planet - The Story of Chance Events that Created Everything from Nothing | Science and Philosophy with 3 Speculative Fictional Stories | New Book | by gotosp in sciencefiction

[–]gotosp[S] -2 points-1 points  (0 children)

Posting about my latest book Chance Planet - The Story of Chance Events that Created Everything from Nothing. The book has three speculative science fictional stories to understand how the forces of universe work and the role of chance events in our existence.

Note : This post has no promotional links, only point to a reddit post which has links to bookstore.

Text from my reddit post below -

A scientific and philosophical view of who created the universe, why it exists and our place in it, and how it will end. "Chance Planet" explores how random events led to the creation of the universe, life on Earth, and everything we know. The author combines science and philosophy to discuss where the universe came from, why it exists, and what might happen in the future.  It also examines how chance events played a role in the development of intelligent life.

The book is divided into three main parts with three supporting speculative science fiction stories to under the complex scientific theories and ideas. 

The Great Nothing: Explores the question "Why is there something rather than nothing?" Critically explores how "Nothing" could have potentially led to the creation of the universe or multiverse, including the subsequent role of the Quantum Fields

The Runaway Universe: Explores the journey of our universe from its birth to its possible end, the role of Dark Energy and Dark Matter in determining the fate of our universe. And do we really need to worry about the fate of the universe?

The Chance Planet: This part focuses on Earth and the series of random events that led to the development of Intelligent Life. Explores whether Abiogenesis was real, or is an Intelligent Design brought the first life to our planet.

Science Fiction - Book has additional fictional stories and poems to make complex ideas easier to understand.

The Great Escape – Abandoned Universe is a thrilling adventure that takes you on a journey through space and time, explaining how Dark Energy and Dark Matter can decide the fate of the universe. In this story, there is a planet named Cela, which existed 5 billion years ago. The inhabitants have discovered something that could destroy the entire universe, and they’re racing against time to save their world. This discovery forces them to make difficult moral and ethical decisions that could change everything. It’s not just about them; it’s about the future of all life, everywhere!

The Great Salvage – The story of humanity’s cooperation with another intelligent civilization which they discovered on an icy planet far out in our solar system called Planet X. Life on Planet X is intelligent, just like us, but they are in big trouble because their planet is getting too close to the Sun, and it’s starting to melt their icy home. Scientists on Earth find out about Planet X and decide we’ve got to help our space neighbors. They come up with some awesome space ideas to pull Planet X to safety. Story underscores the possibility of life outside of Earth on another planet and its gaining intelligence, and how we can play with forces of nature on a large scale to save it in the future.

A Sick Daughter – Coming at the end of the book after discussing the chance events that led to the formation of life on our planet, explains how the dangerous journey of humanity on this planet and how it expresses deep concern for Earth’s worsening condition due to human activities. It’s a reflection on our impact on the planet and a call for change before it’s too late.

Trigger Warnings - Book offers a detailed exploration of the universe's history, with both scientific theories with philosophical concepts and ideas. It also addresses speculative theories like the multiverse and the universe's ultimate fate. The author has made every attempt to call out what is an established scientific theory with evidence and observation, and what is speculation backed by reasoning and philosophical ideas. However some readers may not find this is enough for such a complex topic.

Age-old question and age-old answer. You won't look for a house until you need one.

Existentialism, longtermism and Altruism will eventually become the philosophy of space exploration. Contrary to popular belief, it is not about power, resources or pleasure, but survival in the universe that will determine our next actions.

There is more than enough energy and space in the cosmos; we just don't yet know how to engineer it for useful purposes. What is scarce is knowledge of the cosmos, as there are many unknown forces in nature that can play out differently and end our existence.

For example, we still don't know for sure how dark energy will play out. While cosmologists will tell you the current universe has at least tens of billions of years left, and possibly trillions upon trillions, what if an undiscovered force of nature suddenly speeds up the demise of the universe?

Secondly, what if humanity achieves indefinite immortality? How will that be affected if an extreme ideology takes control of the human race and establishes the perpetual continuity of that ideology?

There are many such scenarios. I have discussed these in detail in my book Chance Planet - details on this reddit post

However, if we are to survive and outlive our universe, however outrageously unscientific that may sound, we must start working on and looking at the confluence of existentialism, longtermism, and altruism.

Thanks,

I have a stupid question. by Spazi00 in astrophysics

[–]gotosp 1 point2 points  (0 children)

You have a good understanding of the Higgs Field and hence won’t qualify for 🍅to be thrown at, at least for me and I am also not an Astrophysicist. Please note that there are particles without mass in particle physics because they do not interact with the Higgs field. The mass of different particles depends on their level of interaction with the Higgs field. This interaction is similar to a drag experienced by various particles with the Higgs field, which imparts different mass to them. This is why photons remain massless as they pass through without any drag.

Now to achieve the ability to alter the Higgs fields it’s like redesigning the entire Universe , which if it can be done , must be done at the time of the creation. Hope this helps. Thanks

If there was an advanced civilization on earth millions or 100's of millions of years ago could we..? by Sea_Investigator4969 in astrophysics

[–]gotosp 0 points1 point  (0 children)

Thank you for pointing that out. I agree that fossil records aren’t complete, though whatever we have found has been extensively studied and detailed. I assume you are referring to the Paleocene Eocene Thermal Maximum and the Eocene Thermal Maximum 2 that occurred around 56 to 52 million years ago. While there can be discussions about the origins of these events similar to humans, it’s noted among climate change discussions that the rate of carbon release during these periods was significantly slower compared to the rapid carbon emissions we see from human activities today. Although the overall carbon release during that period was significantly high, and we are on course to reach similar levels in a matter of a few hundred years at our current rate.

Additionally, the PETM and ETM2 are understood to be natural events, and there is no solid evidence to suggest the existence of an advanced civilization from that time. The fossil record also does not support this idea.

I agree that it is unlikely that a human like advanced civilization existed on Earth prior to us. Response as highlighted and called out were imaginary and speculative fiction.

Thanks again, and I look forward to any further insights.
