Since Mass Exists, Can There Be Negative Mass?
Δημοσιεύτηκε στις 5 Μαΐ 2017
Media
outlets claim researchers have created negative mass, but what they
really created is negative 'effective' mass, which is a little
different.

Cosmologists Prove Negative Mass Can Exist In Our Universe

"Today,
Saoussen Mbarek and Manu Paranjape at the Université de Montréal in
Canada say they've found a solution to Einstein's theory of general
relativity that allows negative mass without breaking any essential
assumptions. Their approach means that negative mass can exist in our
universe provided there is a reasonable mechanism for producing it,
perhaps in pairs of positive and negative mass particles in the early
universe."
'Negative mass' created at Washington State University

"A
negative effective mass can be realized in quantum systems by
engineering the dispersion relation. A powerful method is provided by
spin-orbit coupling, which is currently at the center of intense
research efforts. Here we measure an expanding spin-orbit coupled
Bose-Einstein condensate whose dispersion features a region of negative
effective mass. We observe a range of dynamical phenomena, including the
breaking of parity and of Galilean covariance, dynamical instabilities,
and self-trapping."

"But
perhaps there is a loophole in the equations of Newton and Einstein.
This AV column concerns the idea of negative mass, one such potential
loophole. This idea too has been anticipated in science fiction. In Gene
Wolfe's The Citadel of the Autarch, the fourth volume of the "Book of
the New Sun" trilogy, the Autarch transports the wounded Severian in a
"flier". He explains that it obtains its lift from a boulder-size chunk
of antimatter iron which is repelled by gravity rather than attracted.
The question which we will consider here is whether antimatter, or more
generally negative mass, could provide negative gravity and
gravitational repulsion in this way."
