Quotes About Universe

I have been enormously privileged, through my work, in being able to contribute to our understanding of the universe. But it would be an empty universe indeed if it were not for the people I love, and who love me. Without them, the wonder of it all would be lost on me.

the universe is not infinite in space, but neither does space have any boundary.

As far as we are concerned, events before the big bang can have no consequences, so they should not form part of a scientific model of the universe. We should therefore cut them out of the model and say that time had a beginning at the big bang.

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

The laws of physics demand the existence of something called 'negative energy'.

At some point during our 13.8 billion years of cosmic history, something beautiful happened. This information processing got so intelligent that life forms became conscious. Our universe has now awoken, becoming aware of itself. I regard it a triumph that we, who are ourselves mere stardust, have come to such a detailed understanding of the universe in which we live.

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

A black hole is a region where gravity is so strong that light cannot escape.

His feelings were summed up in his dictum "God does not play dice." But all the evidence is that God is quite a gambler. The universe is like a giant casino with dice being rolled, or wheels being spun, on every occasion.

Kita perlu bergerak lebih cepat daripada cahaya agar bisa sampai ke titik awal sebelum alam semesta berakhir—dan itu tak diperbolehkan!

En consecuencia, si solo sabemos lo que ha sucedido desde el big bang, no podemos determinar lo que sucedió antes. Para nosotros, los sucesos anteriores al big bang no pueden tener consecuencias, de modo que no deberían formar parte de un modelo científico del universo. Por eso deberíamos eliminarlos del modelo y decir que el tiempo tuvo un comienzo en el big bang.

In physics the smallest doll is called the Planck length and is a millimetre divided by a 100,000 billion billion billion.

Why does the universe go to all the bother of existing?

dan kesadaran mengenai betapa kecilnya planet kita sendiri di tengah luasnya alam semesta, hanyalah titik awal.

We could be bounded in a nutshell and count ourselves kings of infinite space.
