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.

One of the basic rules of the universe is that nothing is perfect. Perfection simply doesn't exist.....Without imperfection, neither you nor I would exist

But physics and astronomy offered the hope of understanding where we came from and why we are here. I wanted to fathom the depths of the universe. Maybe I have succeeded to a small extent, but there's still plenty I want to know.

Fizica cuantică ne spune că oricât de amănunțite ar fi observațiile noastre asupra prezentului, trecutul (neobservat), la fel ca viitorul, e nedefinit și există doar ca un spectru de posibilități. Conform fizicii cuantice, universul nu are doar un singur trecut sau o singură istorie.

Suntem produsul fluctuațiilor cuantice din universul foarte timpuriu.

Corpuri precum stelele sau găurile negre nu pot apărea din nimic. Dar un întreg univers poate.

Whatever happens on earth, the rest of the universe will carry on regardless.

To understand the universe at the deepest level, we need to know not only how the universe behaves, but why.Why is there something rather than nothing?Why do we exist?Why this particular set of laws and not some other?”“This is the Ultimate Question of Life, the Universe, and Everything. We shall attempt to answer it in this book. Unlike the answer given in The Hitchhiker’s Guide to the Galaxy, ours won’t be simply “42.

My advice to any heartbroken young girl is to pay close attention to the study of theoretical physics. Because one day there may well be proof of multiple universes. It would not be beyond the realms of possibility that somewhere outside of our own universe lies another different universe. And in that universe, Zayn is still in One Direction.
