Relativity distorted classical expectations in a way that Clavain still did not find entirely intuitive. Slam two objects towards each other, each with individual velocities just below light-speed, and the classical result for their closing velocity would be the sum of their individual speeds: just under twice the speed of light. Yet the true result, confirmed with numbing precision, was that the objects saw each other approach with a combined speed that was still just below the speed of light. Similarly, the relativistic closing velocity for two objects moving towards each other with individual speeds of one-half of light-speed was not light-speed itself, but eight-tenths of it. It was the way the universe was put together, and yet it was not something the human mind had evolved to accept.

I'm sorry to disappoint science fiction fans, but if information is preserved, there is no possibility of using black holes to travel to other universes. If you jump into a black hole, your mass energy will be returned to our universe but in a mangled form which contains the information about what you were like but in a state where it can not be easily recognized. It is like burning an encyclopedia. Information is not lost, if one keeps the smoke and the ashes. But it is difficult to read. In practice, it would be too difficult to re-build a macroscopic object like an encyclopedia that fell inside a black hole from information in the radiation, but the information preserving result is important for microscopic processes involving virtual black holes.

I do not see any reason to assume that the heuristic significance of the principle of general relativity is restricted to gravitation and that the rest of physics can be dealt with separately on the basis of special relativity, with the hope that later on the whole may be fitted consistently into a general relativistic scheme. I do not think that such an attitude, although historically understandable, can be objectively justified. The comparative smallness of what we know today as gravitational effects is not a conclusive reason for ignoring the principle of general relativity in theoretical investigations of a fundamental character. In other words, I do not believe that it is justifiable to ask: What would physics look like without gravitation?

This investigation aims to analyze the type "bourgeois public sphere". Its particular approach is required, to begin with, by the difficulties specific to an object whose complexity precludes exclusive reliance on the specialized methods of a single discipline. Rather, the category. "public sphere" must be investigated within the broad field formerly reflected in the perspective of the traditional science of "politics."' When particular social-scientific discipline, this object disintegrates. The problems that result from fusing aspects of sociology and economics, of constitutional law and political science, and of social and intellectual history are obvious: given the present state of differentiation and specialization in the social sciences, scarcely anyone will be able to master several, let alone all, of these disciplines.

Let us not despair; it is a blessed cause, and success, ere long, will crown our exertions. Already we have gained one victory; we have obtained, for these poor creatures, the recognition of their human nature, which, for a while was most shamefully denied. This is the first fruits of our efforts; let us persevere and our triumph will be complete. Never, never will we desist till we have wiped away this scandal from the Christian name, released ourselves from the load of guilt, under which we at present labour, and extinguished every trace of this bloody traffic, of which our posterity, looking back to the history of these enlightened times, will scarce believe that it has been suffered to exist so long a disgrace and dishonour to this country.

Justice is the end of government. It is the end of civil society. It ever has been, and ever will be, pursued, until it be obtained, or until liberty be lost in the pursuit. In a society, under the forms of which the stronger faction can readily unite and oppress the weaker, anarchy may as truly be said to reign, as in a state of nature where the weaker individual is not secured against the violence of the stronger: And as in the latter state even the stronger individuals are prompted by the uncertainty of their condition, to submit to a government which may protect the weak, as well as themselves: so in the former state, will the more powerful factions be gradually induced by a like motive, to wish for a government which will protect all parties, the weaker as well as the more powerful.
Alexander Hamilton
