As of now, the Yang-Mills existence and mass gap problem remains unsolved in theoretical physics.
The black hole information paradox has not been definitively solved yet. There are ongoing debates and research in the scientific community to understand how information can be preserved in black holes according to the laws of quantum mechanics.
The existence of tachyons, hypothetical particles that travel faster than the speed of light, has not been confirmed. Current theories suggest that tachyons would have imaginary mass and could violate causality, leading to paradoxes. As of now, there is no experimental evidence supporting the existence of tachyons.
The current scientific understanding of the hypothetical particle called the anti graviton is that it has not been observed or proven to exist. While gravitons are theoretical particles that are thought to mediate the force of gravity, the existence of their antimatter counterpart, the anti graviton, has not been confirmed through experimental evidence. Scientists continue to explore and study the properties and potential existence of the anti graviton as part of ongoing research in the field of theoretical physics.
Not invented. Natural element, been around as long as the universe has existed.
An assumed explanation for a problem is a hypothesis or idea that is believed to be the cause of the problem based on available information or prior experiences, even though it has not been fully confirmed or verified. It serves as a starting point for further investigation and problem-solving.
Could the colonies labor problem have been solved without slavery?
It is the solution or sometimes solutions when an equation or a problem has been solved.
Tension
Tension
Yes. All seven have now been accounted for.
The feeling produced by a conflict or problem that has not yet been solved
The problem of water pollution has not been solved because the water pollution already in the water is being brought back by the water cycle. Also people continue to dump waste in the water.
It has not completely. However bans have been implied on CFC's.
The original problem has been solved, but several new ones replace it.
It is a question that has not been answered; a puzzle that has not been solved.
Not quite. The problem of getting rid of the nuclear waste has not been satisfactorily solved.
if your worried you have been naughty then just do lots of really nice things to make up for your naughtieness. There problem solved x
