Is a New Particle Changing the Fate of the Universe?


By Paul Sutter 12 hours ago

Astronomers around the world are in a bit of a tizzy because they can't seem to agree about how fast the universe is expanding.

Ever since our universe emerged from an explosion of a tiny speck of infinite density and gravity, it has been ballooning, and not at a steady rate, either — the expansion of the universe keeps getting faster.

But how quickly it's expanding has been up for a dizzying debate. Measurements of this expansion rate from nearby sources seem to be in conflict with the same measurement taken from distant sources. One possible explanation is that, basically, something funky is going on in the universe, changing the expansion rate.

And one theorist has proposed that a brand-new particle has emerged and is altering the future destiny of our entire cosmos.

1. And one theorist has proposed that a brand-new particle has emerged and is altering the future

"And one theorist has proposed that a brand-new particle has emerged and is altering the future destiny of our entire cosmos."

1) There is no "brand new particle", maybe just new to our observation.

2) It does not alter in any way the "future destiny of our entire cosmos." Only perhaps what we thought was our destiny. Now it is evolving to a new belief (which is also likely not accurate and subject to change).

3. Thanks for the post

I was going to say the same thing.
New particles are like the old canard in 1950s sci-fi movies, where an alien spaceship is made with elements “not known on Earth.”

2. This is fascinating.

I am fortunate enough to reside (most of the time) near CERN. https://home.cern/about

So I pay close attention to articles like this. Thanks for posting.
