Near to a black hole, therefore, nature's weakest interaction exerts the strongest force in the universe. How do physicists reconcile the incredible weakness of gravity relative to the electromagnetic force with the observation that gravity dominates the interactions between the largest objects in the universe?
Arteries are blood vessels that carry blood from your heart to different parts of your body. Raynaud's sometimes is called a disease, syndrome, or phenomenon. The disorder is marked by brief episodes of vasospasm (VA-so-spazm), which is a narrowing of the blood vessels.Vasospasm of the arteries reduces blood flow to the fingers and toes. In people who have Raynaud's, the disorder usually affects the fingers.rteries are blood vessels that carry blood from your heart to different parts of your body.

Raynaud's disease is a common condition that affects blood supply to parts of the body, particularly the fingers and toes. It is named after a 19th century French doctor, Maurice Raynaud, who first recognised the condition. Raynaud's is usually triggered by cold weather, anxiety or stress. Blood vessels go into a temporary spasm which blocks the flow of blood. Affected areas turn white, then blue and finally change to red as the blood flow returns. Symptoms include pain, numbness and pins and needles.
