Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, transversable wormholes, and Alcubierre drives. In special relativity, it is impossible to accelerate an object to the speed of light, or for a massive object to move at the speed of light. However, it might be possible for an object to exist which always moves faster than light.

Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation. Arteries and veins are two of the body’s main type of blood vessels. These vessels are channels that distribute blood to the body. They’re part of two closed systems of tubes that begin and end at the heart. These systems of tubes are either: Pulmonary. The pulmonary vessels are arteries that transport oxygen-poor blood from the heart’s right ventricle to the lungs. Pulmonary veins transport oxygen-rich blood back to the heart’s left atrium. Systemic. The systemic vessels are arteries that carry oxygen-rich blood from the heart’s left ventricle to the tissues in all parts of the body. They then return oxygen-poor blood through the veins back to the heart’s right atrium.

The ability of an element to form bonds with other atoms of the same element is called catenation.

It is the binding of an element to itself through covalent bonds to form chain or ring molecules.

Examples : Carbon is the most common element that exhibits catenation property. That means it can form long hydrocarbon chains and rings like benzene.

The horsepower (hp) is a unit in the foot-pound-second ( fps ) or English system, sometimes used to express the rate at which mechanical energy is expended. It was originally defined as 550 foot-pounds per second (ft-lb/s).
A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW).
