Can we make negative matter?
Answers
Washington State University physicists have created a fluid with negative mass, which is exactly what it sounds like. Hypothetically, matter can have negative mass in the same sense that an electric charge can be either negative or positive.
Answer:
No, not till now.
Explanation:
Negative matter is the opposite of everyday, positive matter. It has negative mass instead of positive mass. Positive matter has a gravitational pull on objects around it and, like the moon to the Earth, the gravitational field of this positive mass attracts objects to it.
Negative mass is the hypothetical idea that matter can exist with mass of the opposite sign to the ordinary stuff. They generally conclude that negative matter cannot exist because it breaks one of the essential assumptions behind Einstein's theory of general relativity.
