Physicists Have Demonstrated That ‘Impossible’ Tetraquarks Can Exist After All

An exotic kind of particle so mysterious that it was suspected to be impossible has finally been identified by physicists – and not just once, but twice.

Two new theoretical predictions of an elusive form of matter called tetraquarks provide the firmest evidence yet that these strange particles really do exist after all, setting the stage for an imminent new era of understanding in subatomics.

Can particles be created by humans that have never existed or will ever exist in nature or are we just replicating them from very specific conditions.

“predict tetraquarks can assemble from two bottom quarks along with an anti-up quark and an anti-down quark – with the anti-quarks being like twins to regular quarks, but with the opposite electrical polarity.”

Weird, but I’m not denying it unless the two theoretical models require physics beyond the standard model such as fr or loop quantum.

They did exist and do exist. They used to exist in great numbers in the big bang. And they are still being created naturally by the most powerful cosmic rays.

PS. I love it when people call 10 ^-13 seconds “a relative eternity”.

Nothing can be created by humans that have never existed.

HTH.

Err…I think some new elements were created by humans but I will concede to you that the very building blocks of all matter were created by God.

The “new elements” were ones which don’t exist on Earth but are found in stars everywhere.
