With the advent of general relativity it has been entertained by serious physicists. But, especially in the philosophy literature, there have been arguments that time travel is inherently paradoxical. The most famous paradox is the grandfather paradox: you travel back in time and kill your grandfather, thereby preventing your own existence. To avoid inconsistency some circumstance will have to occur which makes you fail in this attempt to kill your grandfather. Doesn't this require some implausible constraint on otherwise unrelated circumstances? We examine such worries in the context of modern physics. 1. A Botched Suicide

Physics From Wikipedia, the free encyclopedia. Physics portal Physics (from the Greek phusikos ), "natural", and φύσις ( phusis ), "nature") is the science of the natural world in the broadest sense, dealing with matter and energy and the fundamental forces of nature that govern the interactions between particles ; it was called natural philosophy until the late 19th century Physicists study a wide range of physical phenomena spanning all length scales, from the sub-nuclear particles of which all ordinary matter is made ( particle physics ) to the material Universe as a whole ( cosmology Physics discoveries find applications throughout the other natural sciences , since matter and energy are the basic constituents of the natural world. Some of the properties studied in physics are common to all material systems, such as the conservation of energy . Such properties are often referred to as laws of physics . Physics is sometimes said to be the "fundamental science", because each of the other natural sciences ( biology chemistry geology , etc.) deals with particular types of material systems that obey the laws of physics. For example, chemistry is the science of molecules and the chemicals that they form in the bulk. The properties of a chemical are determined by the properties of the underlying molecules, which are accurately described by areas of physics such as
