A Quote by Carl Sagan
If we could travel into the past, it's mind-boggling what would be possible. For one thing, history would become an experimental science, which it certainly isn't today. The possible insights into our own past and nature and origins would be dazzling. For another, we would be facing the deep paradoxes of interfering with the scheme of causality that has led to our own time and ourselves. I have no idea whether it's possible, but it's certainly worth exploring.

But the things is, you see, that two people can never actually become one no matter how close they are. And it would not be desirable even if it were possible. What would happen when one of them died? It would leave the other as a half a person, and that would be a dreadful thing. We must each be a whole person and therefore we each need some privacy to be alone with ourselves and our own feelings.
What would happen if history could be rewritten as casually as erasing a blackboard? Our past would be like the shifting sands at the seashore, constantly blown this way or that by the slightest breeze. History would be constantly changing every time someone spun the dial of a time machine and blundered his or her way into the past. History, as we know it, would be impossible. It would cease to exist.
Well we thought a church wedding would be possible. It certainly would be possible in the Catholic church because after all my first marriage had been annulled by Pope Paul VI. The problem arose in that Prince Michael could not have Catholic children.
Lots of things are not possible for municipalities, suburbs, or collections of them now. They are not possible and they would become possible, because they would have more authority. They would have the same authority as a province now.
In politics as in religion, my tenets are few and simple. The leading one of which, and indeed that which embraces most others, is to be honest and just ourselves and to exact it from others, meddling as little as possible in their affairs where our own are not involved. If this maxim was generally adopted, wars would cease and our swords would soon be converted into reap hooks and our harvests be more peaceful, abundant, and happy.
All our knowledge hast its origins in our perceptions … In nature there is no effect without a cause … Experience never errs; it is only your judgments that err by promising themselves effects such as are not caused by your experiments … Science is the observation of things possible, whether present or past; prescience is the knowledge of things which may come to pass.
Looking for honest ways to lift one another would . . . be more beneficial to our own self-esteem, for we would see more good in ourselves. We would cease to be so critical of our weaknesses and would find ways to allow our weaknesses to become strengths with God's help.
From my point of view, why shouldn't I work in every possible mode, to see if it's viable? "Los Gigantes" would not have worked as a straightforward, naturalistic tale. Part of the fun of it is that it's so preposterous and yet at the same time, it could have happened. Think of eugenics. Hitler certainly would have been doing it if he could have.
Certainly nothing is easier than to rewrite history. If we had made Taiwan a separate state, it would have led to a fundamental conflict with China, and probably to war. Certainly in the long term, it would have led to war.
Probably if half a kilogram [of radium] were in a bottle on that table it would kill us all. It would almost certainly destroy our sight and burn our skins to such an extent that we could not survive. The smallest bit placed on one's arm would produce a blister which it would need months to heal.
It would not be possible for Noah to do in our day what he was permitted to do in his own ... The inspector would come and examine the Ark, and make all sorts of objections.
The company that employed me strived only to serve up the cheapest fare that the customer would tolerate, churn it out as fast as possible, and charge as much as they could get away with. If it were possible to do so, the company would sell what all businesses of its kind dream about selling, creating that which all of our efforts were tacitly supposed to achieve: the ultimate product -- Nothing. And for this product they would command the ultimate price -- Everything.
The chemical differences among various species and genera of animals and plants are certainly as significant for the history of their origins as the differences in form. If we could define clearly the differences in molecular constitution and functions of different kinds of organisms, there would be possible a more illuminating and deeper understanding of question of the evolutionary reactions of organisms than could ever be expected from morphological considerations.
Is it possible that there is something we don't fully understand about God and about Life, the understanding of which would change everything? Is it possible that there is something we don't understand about ourselves, and about who we are, the understanding of which would alter our lives forever for the better? Yes. The answer is yes.
Youth would be too happy, might it add to its own beauty and felicity the wisdom and experience of riper years. Were it possible for it to realize the worth of time, as life's receding hours reveal it, how rapidly would it press on towards perfection!
A science of all these possible kinds of space [the higher dimensional ones] would undoubtedly be the highest enterprise which a finite understanding could undertake in the field of geometry... If it is possible that there could be regions with other dimensions, it is very likely that God has somewhere brought them into being.
