Does string theory have any meaning

String theory, the


The theory of quantum gravity is still being sought. That doesn't mean that there aren't any candidates for such a theory yet. The best known of them is the so-called string theory. It assumes that matter is ultimately made up of tiny strings, the strings being structures with ten dimensions. However, since the strings are rolled up into tiny tangles, in practice one would only be able to perceive the three known spatial dimensions. The existence of an invisible dimension sounds like a daring speculation. [Die Welt, 07/19/2017]

For decades he [Stephen Hawkings] has been dealing with borderline questions in physics, especially string theory, cosmology and black holes. [Süddeutsche Zeitung, 02.26.2014]

According to the researchers, this constant renewal of the universe can also be explained by the mathematics of so-called string theory and its further developments, which have found more and more supporters among theoretical physicists in recent years. [Der Spiegel, April 26, 2002 (online)]

The easiest way to formulate string theories, mathematically speaking, is in ten space-time dimensions. [Süddeutsche Zeitung, 03.08.1999]

The physicists are working hard to replace the standard model, and many are thinking of one of the string theories in which gravity is combined with the other forces. [Die Zeit, July 16, 1998]
