In real time, the universe has a beginning and an end at singularities that form a boundary to space-time and at which the laws of science break down.

What this quote means

This quote discusses the boundaries of our understanding of the universe, specifically at its beginnings and ends where current scientific laws fail.

Stephen Hawking's quote reflects on the nature of the universe, explaining that there are points, known as singularities, where traditional physics and science cannot adequately describe what occurs. These singularities represent the limits of our knowledge and the framework of space-time, suggesting that understanding the full nature of the universe involves grappling with these mysterious boundaries.

I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken down computers; that is a fairy story for people afraid of the dark.

It surprises me how disinterested we are today about things like physics, space, the universe and philosophy of our existence, our purpose, our final destination. Its a crazy world out there. Be curious.

I was not a good student. I did not spend much time at college; I was too busy enjoying myself.

The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic but technological-technologies that flowed directly from advances in basic science. Clearly, no scientist better represents those advances than Albert Einstein: TIME's Person of the Century.

My emotional investment is in finding truth. If string theory is wrong, I'd like to have known that yesterday. But if we can show it today or tomorrow, fantastic.

Since we proposed punctuated equilibria to explain trends, it is infuriating to be quoted again and again by creationists-whether through design or stupidity, I do not know-as admitting that the fossil record includes no transitional forms. Transitional forms are generally lacking at the species level, but they are abundant between larger groups.

It's often better to read first-rate science fiction than second-rate science - it's far more stimulating, and perhaps no more likely to be wrong.

One can think of any given axiom system as being like a computer with a certain limited amount of memory or processing power. One could switch to a computer with even more storage, but no matter how large an amount of storage space the computer has, there will still exist some tasks that are beyond its ability.

I thought that tackling aging and the mechanisms that promote life would be worth figuring out. I wanted to learn why it is that some people are healthier than others and why some people live to 110 and others only to 60 or 70.
