Don`t worry humans will not be around to see it. we know planets have a beginning and an end and suns burnout.

Theoretically, like forest animals fleeing a fire, humans should get off this rock and spread as far and wide as they can.

Conventional humans may (almost certainly will) eventually go extinct, but at least something of us might survive out there.

Isn't that the basic drive that moves us to have children and expand in the first place?

In the meanwhile, I've always felt a touch of melancholy that even the universe would end up in the grave, cold dark and forgotten, with everything anybody anywhere did, human and alien, being lost forever with nobody left to care.

At least with a collapse and possibly/maybe a new big bang, there might be hope for something.

My utterly amateurish, don't know what I'm talking about, uneducated hypothesis is...

Accepting that inflation is correct, and it does seem to be... the inflaton field prior to the hot big bang was rapidly expanding, when it stopped expanding all the energy was dumped into the field, particles created, they jostled together, and a hot big bang ensued.

Today, the universe's expansion is accelerating (dark energy) and a very, VERY long way into the future when not even particles are intact, what do we end up with? A scalar field identical to the inflaton field that was also a scalar field. When that stops expanding, all the energy is again dumped into the field and once again we have a new big bang, a cyclic universe.

How much is the Nobel prize again? 😏

Our sun will expand to almost encompass the Earth. It will be a red giant. Maybe, by that time, we will be high up on the Kardashev scale and use a mega gravity tractor to drag the Earth further away, back into the new Goldilocks zone? 😁

Well if humans want to fund that pipe dream someone will take their money. that`s how the rich get richer the gap between the rich Elits, and the pore grows widder.

The rich don`t do anything for love the balance sheet is king. you don`t become a two trillion industry without make hard choices.

Our only hope is to get up to the proposed Type V on the Kardashev Scale and move to another universe:

"A Type V civilization would be advanced enough to to escape their universe of origin and explore the multiverse."

It's cosmology, not science 😉

😲 I didn't know it went that high. You mean like Q from Star Trek?

I think so. It's not really an extension of the Kardashev Scale but is inspired by it.

“In another article, Zoltan Galántai suggests considering another scale, no longer based on energy consumption, but on a civilization's ability to survive natural and cosmic disasters. Type I would describe a civilization capable of surviving a local natural disaster, like the Anasazi. A Type II civilization would have the means to withstand a regional or continental disaster, and finally Type III could face a global disaster such as an asteroid's impact, a supervolcano's eruption, or an ice age. Beyond the first three types are civilizations that have scattered throughout the galaxy. The Type IV civilization would still be vulnerable to some cosmic threats, while the Type V civilization would be technically immortal, as no cosmic catastrophe could reach it.”

If you have not already, and find the inclination, you might want to take a look at The Xeelee Sequence.

Quote

 

The Xeelee Sequence (/ˈziːliː/; ZEE-lee) is a series of hard science fiction novels, novellas, and short stories written by British science fiction author Stephen Baxter. The series spans billions of years of fictional history, centering on humanity's future expansion into the universe, its intergalactic war with an enigmatic and supremely powerful Kardashev Type V alien civilization called the Xeelee (eldritch symbiotes composed of spacetime defects, Bose-Einstein condensates, and baryonic matter), and the Xeelee's own cosmos-spanning war with dark matter entities called Photino Birds. The series features many other species and civilizations that play a prominent role, including the Squeem (a species of group-mind aquatics), the Qax (beings whose biology is based on the complex interactions of convection cells), and the Silver Ghosts (colonies of symbiotic organisms encased in reflective skins). Several stories in the Sequence also deal with humans and posthumans living in extreme conditions, such as at the heart of a neutron star (Flux), in a separate universe with considerably stronger gravity (Raft), and within eusocial hive societies (Coalescent).

The Xeelee Sequence deals with many concepts stemming from the fringe of theoretical physics and futurology, such as artificial wormholes, time travel, exotic-matter physics, naked singularities, closed time-like curves, multiple universes, hyper advanced computing and artificial intelligence, faster-than-light travel, spacetime engineering, quantum wave function beings, and the upper echelons of the Kardashev scale. Thematically, the series deals heavily with certain existential and social philosophical issues, such as striving for survival and relevance in a harsh and unknowable universe, the effects of war and militarism on society, and the effects that come from a long and unpredictable future for humanity with strange technologies.

As of August 2018, the series is composed of 9 novels and 53 short pieces (short stories and novellas, with most collected in 3 anthologies), all of which fit into a fictional timeline stretching from the Big Bang's singularity of the past to the eventual heat death of the universe and Timelike Infinity's singularity of the future.

An omnibus edition of the first four Xeelee novels (Raft, Timelike Infinity, Flux, and Ring), entitled Xeelee: An Omnibus, was released in January 2010. In August 2016, the entire series of all novels and stories (up to that date) was released as one volume in e-book format entitled Xeelee Sequence: The Complete Series. Baxter's Destiny's Children series is part of the Xeelee Sequence.

Only if some of use (not all) continue to choose a path of ignorance/denial rather than education and understanding.  We are more than capable of learning now to transports ourselves off this planet and onto another planet in a self-sustaining space craft ... key being "self sustaining" ... lessons we're still learning perhaps?

As much as many of us humans focus on things that don't matter like gender identification, race identification, skin color, partner choice, ceremony, money, etc. ... there are plenty of us humans that can focus on how to sustain the human race and what needs to be done.  I'm optimistic.

Even type IV is getting a bit farfetched, maybe. 🤔
