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.

This apparent loss of information, known as the information paradox, has troubled scientists for the last forty years, and still remains one of the biggest unsolved problems in theoretical physics.

philosophy is dead. Philosophy has not kept up with modern developments in science, particularly physics. Scientists have become the bearers of the torch of discovery in our quest for knowledge.

I would see the end of physics as we know it, but now I think the wonder of discovery will continue long after I am gone. We are close to some of these answers, but we are not there yet.

A model is a good model if it: Is elegant Contains few arbitrary or adjustable elements Agrees with and explains all existing observations Makes detailed predictions about future observations that can disprove or falsify the model if they are not borne out. For

Evolution has ensured that our brains just aren't equipped to visualise 11 dimensions directly. However, from a purely mathematical point of view it's just as easy to think in 11 dimensions, as it is to think in three or four. Stephen Hawking

And one final point - we never really know where the next great scientific discovery will come from, nor who will make it. Opening up the thrill and wonder of scientific discovery, [...], greatly increases the chances of finding and inspiring the new Einstein. Wherever she might be.

Gagasan bahwa kita bisa berjalan mengelilingi alam semesta dan kembali ke tempat semula itu cocok dijadikan fiksi sains, tapi tidak punya banyak arti praktis karena bisa ditunjukkan bahwa alam semesta keburu runtuh menjadi berukuran nol sebelum kita bisa kembali ke titik awal.

Paus bilang kepada kami bahwa mempelajari perkembangan alam semesta sesudah Ledakan Besar itu boleh-boleh saja, tapi kami sebaiknya tak mencari tahu mengenai Ledakan Besar karena itulah saat Penciptaan yang merupakan karya Tuhan.

Sains tampaknya telah mengungkap satu set hukum yang memberi tahu kita bagaimana alam semesta akan berkembang seiring waktu jika kita mengetahui keadaannya pada saat apa pun, dalam batas-batas yang ditetapkan oleh kaidah ketidakastian. Hukum-hukum itu boleh jadi aslinya ditetapkan oleh Tuhan, tapi tampaknya Dia sudah membiarkan alam semesta berkembang sesuai hukum-hukum itu dan sekarang tak lagi ikut campur dalam alam semesta.

Stephen Hawking

The first scientific description of time was given in 1689 by Sir Isaac Newton, who held the Lucasian chair at Cambridge that I used to occupy (though it wasn't electrically operated in his time).

The low esteem in which science and scientists are held is having serious consequences. We live in a society that is increasingly governed by science and technology, yet fewer and fewer young people want to go into science.

Even if it turns out that time travel is impossible, it is important that we understand why it is impossible.
