Dark energy is weakening and the universe could (eventually) collapse, study says

Dark energy, a mysterious force that scientists believe is behind the accelerated expansion of the universe, is weakening — which could result in the universe over the course of billions of years collapsing on itself, according to new research.

An international group of more than 900 researchers studying the expansion of the universe presented their findings on Wednesday during the American Physical Society's Global Physics Summit in Anaheim, Calif.

The scientists, who are collaborating on something called the Dark Energy Spectroscopic Instrument (DESI) are studying the history of the universe's expansion out to 11 billion years in the past. They analyzed three years of data from 15 million galaxies and quasars using a series of instruments, including a telescope.

Scientists have believed dark energy was a "cosmological constant," but it is actually changing over time in unexpected ways.

Mustapha Ishak, co-chair of DESI and an astrophysics professor at the University of Texas at Dallas, tells NPR that current data shows that, at the beginning of the universe, dark energy was very strong. But it has weakened with time and will continue to do so, he says. For that reason, Ishak argues it's time for scientists to update their understanding of the universe.

Gonna need a Universe Collapse insurance policy, for $1M.

So now we are back to cyclical models of the universe? Big Crunch —> Big Bang —> Big Crunch ad infinitum

We only get to see a short duration. My theory is the Universe is constantly expanding and contracting like a rubber ball.

Well, there is probably a few forms of gravity we don’t know about.

My son won’t do his homework because the universe is expanding! “What’s the use?” he says!

Keep in mind they have no idea what it is, just that something is happening.

And why don’t the universal gravitational forces cause the universe to collapse on itself and why is the universe actually expanding?

Whoa, that’s because of dark energy dude.

What is that?

It’s like this stuff that keeps the universe expanding. It’s science dude.

I'm pretty busy. I am going to need at least a week's notice. Two weeks even better.

900 “scientists” discussing what may happen billions years in the future, while there is a nationwide shortage of plumbers making up to $200K per years. Let’s ask ourselves: what is more important for this country, a clogged toilet or a potential destruction of the Universe?

“You, Lord, did lay the foundation of the earth in the beginning, and the heavens are the works of Your hands. They will perish,but You remain and continue permanently; they will all grow old and wear out like a garment. Like a mantle You will roll them up,
and they will be changed.....” Hebrews 1:10-12

I’m so scared I think I’ll go out and buy another box of covid masks and maybe get a few more covid boosters. I just don’t know what else to do.

Seriously, I don’t think it will happen. But if it does we’d never know it. Just like those clowns going down to the Titanic that went too deep and imploded. It happened so fast they never knew it.
