In astrophysics, weakly interacting massive particles or WIMPs, are hypothetical particles serving as one possible solution to the dark matter problem. These particles interact through the weak force and gravity, and possibly through other interactions no stronger than the weak force. Because they do not interact with electromagnetism they cannot be seen directly, and because they do not interact with the strong nuclear force they do not react strongly with atomic nuclei.
This combination of properties gives WIMPs many of the properties of neutrinos, except for being far more massive and therefore slower.

Famous quotes containing the words weakly, massive and/or particles:
“Let’s not quibble! I’m the foe of moderation, the champion of excess. If I may lift a line from a die-hard whose identity is lost in the shuffle, “I’d rather be strongly wrong than weakly right.””
—Tallulah Bankhead (1903–1968)
“It was the feeling of a passenger on an ocean steamer whose mind will not give him rest until he has been in the engine-room and talked with the engineer. She wanted to see with her own eyes the action of primary forces; to touch with her own eyes the action of primary forces; to touch with her own hand the massive machinery of society; to measure with her own mind the capacity of the motive power. She was bent upon getting to the heart of the great American mystery of democracy and government.”
—Henry Brooks Adams (1838–1918)
“When was it that the particles became
The whole man, that tempers and beliefs became
Temper and belief and that differences lost
Difference and were one? It had to be
In the presence of a solitude of the self....”
—Wallace Stevens (1879–1955)
