But this means it must include gravity. And the difference between gravity and the other forces is naturally explained, in terms of the difference between open and closed strings. For the first time, gravity plays a central role in the unification of the forces.”",

The chemist's atom consists of nucleus and electrons; the nucleus is made up of protons and neutrons; the protons and neutrons are made up of what the particle physicist calls quarks. That is where we are today, but we don't know whether this is the end of the line; this is not what concerns us in our present discussion. Rather, Democritus's concept of the individual unit of matter was shattered by the discovery that every particle can be made to meet its antiparticle and vanish into pure energy in the process. Particle and antiparticle together blend into structureless energy, and may reemerge as different particles.”",
