Quotes About Universe

Ne f?urim concepte mentale despre c?minul nostru, despre copaci, despre al?i oameni, despre electricitatea care curge din prize, despre atomi, molecule ?i alte universuri. Aceste concepte mentale sunt singura realitate pe care o cunoa?tem.

I believe the universe is governed by the laws of science. These laws may have originally been decreed by God, but it appears that he has since left the universe to evolve according to them and does not now intervene in it.

There are at least three different arrows of time. First, there is the thermodynamic arrow of time, the direction of time in which disorder or entropy increases. Then, there is the psychological arrow of time. This is the direction in which we feel time passes, the direction in which we remember the past but not the future. Finally, there is the cosmological arrow of time. This is the direction of time in which the universe is expanding rather than contracting.

Corpuri precum stelele sau g?urile negre nu pot ap?rea din nimic. Dar un întreg univers poate.

Why is there something rather than nothing? Why do we exist? Why this particular set of laws and not some other?

In an unchanging universe a beginning in time is something that has to be imposed by some being outside the universe;

contains on average some one hundred billion stars. If a star were a grain of salt, you could fit all the stars visible to the naked eye on a teaspoon, but all the stars in the universe would fill a ball more than eight miles wide.

It means the universe itself, in all its mind-boggling vastness and complexity, could simply have popped into existence without violating the known laws of nature.

Contanto que o universo tenha tido um início, podemos supor que houve um criador. Mas, se o universo fosse de fato absolutamente contido em si mesmo, sem contorno nem borda, ele não teria início nem fim: ele simplesmente seria. Nesse caso, qual é o papel de um criador?

but also that it is possible that nothing caused the Big Bang. Nothing.

Do the laws governing the universe allow us to predict exactly what is going to happen to us in the future? The short answer is no, and yes. In principle, the laws allow us to predict the future. But in practice the calculations are often too difficult.

Our modern picture of the universe dates back to only 1924, when the American astronomer Edwin Hubble demonstrated that ours was not the only galaxy.

Stephen Hawking

Remember to look up at the stars and not down at your feet. Try to make sense of what you see, wonder about what makes the universe exist. Be curious. However difficult life may seem, there is always something you can do and succeed at. It matters that you don't just give up.

we can really be sure of is that even if the universe is going to recollapse, it won't do so for at least another ten thousand million years, since it has already been expanding for at least that long. This should not unduly worry us: by that time, unless we have colonized beyond the Solar System, mankind will long since have died out, extinguished along with our sun!

For every event in space-time we may construct a light cone (the set of all possible paths of light in space-time emitted at that event), and since the speed of light is the same at every event and in every direction, all the light cones will be identical and will all point in the same direction.

Solo somos una raza avanzada de monos....pero podemos comprender el universo

the universe is governed by a set of rational laws that we can discover and understand.

The role played by time at the beginning of the universe is, I believe, the final key to removing the need for a grand designer and revealing how the universe created itself.

We have this one life to appreciate the grand design of the universe, and for that I am extremely grateful.

In order to understand the origin of the universe, one therefore has to incorporate the Uncertainty Principle into Einstein's general theory of relativity. This has been the great challenge in theoretical physics for at least the last thirty years. We haven't solved it yet, but we have made a lot of progress.

Fizica cuantic? ne spune c? oricât de am?nunÈ›ite ar fi observaÈ›iile noastre asupra prezentului, trecutul (neobservat), la fel ca viitorul, e nedefinit È™i exist? doar ca un spectru de posibilit??i. Conform fizicii cuantice, universul nu are doar un singur trecut sau o singur? istorie.

Nuestras mentes son libres de explorar todo el universo y de ir con valentía incluso hasta donde Star Trek teme pisar.

La física cuántica es un nuevo modelo de la realidad que nos proporciona una imagen del universo que en muchos conceptos fundamentales para nuestra comprensión intuitiva de la realidad carecen de significado.
