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.
