192 Quotes by Lawrence M. Krauss

We all trust each other to some extent. We have to rely on experts to some extent, but we should learn to be sceptical.

Science is not just there for technology. It's part of what addressing who you are in the universe and understanding your place in the cosmos. Good art, good literature, good music - all of that is for that and science is a part of it.

What science is all about is a process. It's like saying, "Well, is it important for people to know that World War II happened?" Well it's part of what makes us who we are. And so, there's basic bits of science we need to know.

We now know that we are more insignificant than we ever imagined. If you get rid of everything we see, the universe is essentially the same. We constitute a 1 percent bit of pollution in a universe . . . we are completely irrelevant.

Forget Jesus. The stars died so that you could be here today.

Discerning the merits of competing claims is where the empirical basis of science should play a role.

In this sense, science, as physicist Steven Weinberg has emphasized, does not make it impossible to believe in God, but rather makes it possible to not believe in God.

As a scientist, I don't believe anything. Science shouldn't use the word belief. There are things more likely and less likely. Science can say nothing with absolute certainty.
