So they say. From ScienceDaily:

A University of Queensland-led international team of researchers say they have discovered “a new kind of quantum time order.”

UQ physicist Dr Magdalena Zych said the discovery arose from an experiment the team designed to bring together elements of the two big — but contradictory — physics theories developed in the past century.

“Our proposal sought to discover: what happens when an object massive enough to influence the flow of time is placed in a quantum state?” Dr Zych said.

She said Einstein’s theory described how the presence of a massive object slowed time.

“Imagine two space ships, asked to fire at each other at a specified time while dodging the other’s attack,” she said.

“If either fires too early, it will destroy the other.”

“In Einstein’s theory, a powerful enemy could use the principles of general relativity by placing a massive object — like a planet — closer to one ship to slow the passing of time.”

“Because of the time lag, the ship furthest away from the massive object will fire earlier, destroying the other.”

Dr Zych said the second theory, of quantum mechanics, says any object can be in a state of “superposition”

“This means it can be found in different states — think Schrodinger’s cat,” she said.

Dr Zych said using the theory of quantum mechanics, if the enemy put the planet into a state of “quantum superposition,” then time also should be disrupted.

“There would be a new way for the order of events to unfold, with neither of the events being first or second — but in a genuine quantum state of being both first and second,” she said.

UQ researcher Dr Fabio Costa said although “a superposition of planets” as described in the paper — may never be possible, technology allowed a simulation of how time works in the quantum world — without using gravity.

“Even if the experiment can never be done, the study is relevant for future technologies,” Dr Costa said. Paper. (open access) – Magdalena Zych, Fabio Costa, Igor Pikovski, Časlav Brukner. Bell’s theorem for temporal order. Nature Communications, 2019; 10 (1) DOI: 10.1038/s41467-019-11579-x More.

The theory is, it will help quantum computers work faster. Let’s see it closer to home first.

    Wait wait the experiment was a Scenario about space ships battling in high gravity?

    By the way what if the slowing of time is simply the slowing of particle movement due to the increased gravity? you’re literally just slowing down the entropy of the particle it’s not stopping the flow of time and we would not know the difference

    If time is affected by mass then there must be a force that restores time when the mass is removed. So now we have another unknown force to study.
    If time is affected by mass, what is the speed of the effect as the mass approaches? This requires time to exist in at least two dimensions.
    This notion does not explain anything, it only proposes more undefined fudge factors.

    SmartAZ- Perhaps you should read about time dilation.

    ET – “Time dilation
    According to the theory of relativity, time dilation is a difference in the elapsed time measured by two observers, either due to a velocity difference relative to each other, or by being differently situated relative to a gravitational field.Wikipedia”
    Theory of relativity has been disproved several times. https://www.thunderbolts.info/wp/2013/11/29/common-misconception-9-who-disproved-einstein/
