Quotes About Time

In conclusion, rapid space travel and travel back in time can't be ruled out according to our present understanding. They would cause great logical problems, so let's hope there's a Chronology Protection Law to prevent people going back and killing their parents.

If the boundary condition of the universe is that it has no boundary in imaginary time, it won't have just a single history. There are many histories in imaginary time and each of them will determine a history in real time. Thus we have a superabundance of histories for the universe. What picks out the particular history, or set of histories that we live in, from the set of all possible histories of the universe?

The lack of an absolute standard of rest meant that one could not determine whether two events that took place at different times occurred in the same position in space. For example, suppose our Ping-Pong ball on the train bounces straight up and down, hitting the table twice on the same spot one second apart. To someone on the track, the two bounces would seem to take place about thirteen meters apart, because the tram would have traveled that far down the track between the bounces.

One way or another, I regard it as almost inevitable that either a nuclear confrontation or environmental catastrophe will cripple the Earth at some point in the next 1,000 years which, as geological time goes, is the mere blink of an eye. By then I hope and believe that our ingenious race will have found a way to slip the surly bonds of Earth and will therefore survive the disaster.

Como veremos, o conceito de tempo não tem significado antes do início do universo. Isso foi observado pela primeira vez por santo Agostinho. Quando lhe perguntavam "O que Deus fazia antes de criar o universo?", sua resposta não era "Ele estava preparando o inferno para pessoas que fizessem perguntas como essa". Em vez disso, respondia que o tempo era uma propriedade do universo criada por Deus e não existia antes dele. Quando

The laws of science determine the evolution of the universe, given its state at one time.

We are all time travellers, journeying together into the future. But let us work together to make that future a place we want to visit.

The twentieth century saw man's view of the universe transformed: we realized the insignificance of our planet in the vastness of the universe, and we discovered that time and space we curved and inseparable , that the universe was expanding, and that it had a beginning in time.

the light that we see from distant galaxies left them millions of years ago, and in the case of the most distant object that we have seen, the light left some eight thousand million years ago. Thus, when we look at the universe, we are seeing it as it was in the past.

You can't get to a time before the Big Bang because there was no time before the Big Bang. We have finally found something that doesn't have a cause, because there was no time for a cause to exist in.

Because everyday could be my last I have the desire to make the most of each and every minute. I try to lead as normal a life l as possible and not think about my condition or regret the thing it prevents me from doing which are not that many .my goal is simple it is complete understanding of the universe. Why it is as it is and why it exists at all.

DüÅŸük h?z? ve zay?f kuvveti ilgilendiren durumlarda zaman? ve uzay? ayr? ayr? ele alabiliriz. Oysa, genelde zaman ve uzay birbirine geçmiÅŸtir ve bunlar?n geniÅŸlemesi veya s?k??mas? belli oranda birbirine kar??may? içerir.

This says that in any closed system disorder, or entropy, always increases with time. In other words, it is a form of Murphy's law: things always tend to go wrong!

If you fall towards a black hole feet first, gravity will pull harder on your feet than your head, because they are nearer the black hole. The result is that you will be stretched out lengthwise, and squashed in sideways.

Apa yang Tuhan lakukan sebelum Dia menciptakan alam semesta? Agustinus tak menjawab: Dia mempersiapkan Neraka untuk orang-orang yang bertanya seperti itu. Dia malah mengatakan bahwa waktu adalah bagian alam semesta yang Tuhan ciptakan, dan waktu tidak ada sebelum permulaan alam semesta.

Alam semesta mengembang tidak melenyapkan pencipta, tapi jelas membatasi kapan pencipta bisa melakukan penciptaan!

On the other hand, if the universe is expanding, there may be physical reasons why there had to be a beginning. One could still imagine that God created the universe at the instant of the big bang, or even afterwards in just such a way as to make it look as though there had been a big bang, but it would be meaningless to suppose that it was created before the big bang. An expanding universe does not preclude a creator, but it does place limits on when he might have carried out his job!

if the sun were to cease to shine at this very moment, it would not affect things on earth at the present time because they would be in the elsewhere of the event when the sun went out.

Todos somos viajeros en el tiempo, viajamos juntos hacia el futuro. Trabajemos unidos para construir ese futuro, un lugar que nos guste visitar. Seamos valientes, curiosos, decididos, superemos las dificultades. Se puede conseguir.

En el instante del Big Bang, algo maravilloso sucedió con el tiempo. El tiempo mismo comenzó.

What happened before the beginning ? What was God doing before he made the world? Was he preparing Hell for people who asked such questions?

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.
