The lack of understanding of something is not evidence for God. It's evidence of a lack of understanding.— Lawrence M. Krauss
The most fascinating Lawrence M. Krauss quotes that are little-known but priceless
Every atom in your body came from a star that exploded.
And the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: you are all stardust.
The one experience that I hope every student has at some point in their lives is to have some belief you profoundly, deeply hold, proved to be wrong because that is the most eye-opening experience you can have, and as a scientist, to me, is the most exciting experience I can ever have.
Neutrinos alone, among all the known particles, have ethereal properties that are striking and romantic enough both to have inspired a poem by John Updike and to have sent teams of scientists deep underground for 50 years to build huge science-fiction-like contraptions to unravel their mysteries.
The purpose of education is not to validate ignorance but to overcome it.
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.
The universe is the way it is , whether we like it or not.
The existence or nonexistence of a creator is independent of our desires . A world without God or purpose may seem harsh or pointless, but that alone doesn ' t require God to actually exist.
[The writers of the holy books] did not even know the earth revolves around the sun. Why are we listening?
Forget Jesus. The stars died so that you could be here today.
Whatever the evolutionary basis of religion, the xenophobia it now generates is clearly maladaptive.
Philosophy used to be a field that had content, but then natural philosophy became physics, and physics has only continued to make inroads. Every time theres a leap in physics, it encroaches on these areas that philosophers have carefully sequestered away to themselves, and so then you have this natural resentment on the part of philosophers.
Nothing can create something all the time due to the laws of quantum mechanics, and it's - it's fascinatingly interesting.
Celebrate our brief moment in the sun
The ultimate arbiter of truth is experiment, not the comfort one derives from one's a priori beliefs, nor the beauty or elegance one ascribes to one's theoretical models.
90% of the mass in your body comes from empty space.
If you have nothing in quantum mechanics, you will always have something.
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.
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.
The amazing thing is that every atom in your body came from a star that exploded.
Aside from communications satellites, space is devoid of industry.
The really important thing is learning how to sceptically question and rely on empirical evidence.
A truly open mind means forcing our imaginations to conform to the evidence of reality, and not vice versa.
Organized religion, wielding power over the community, is antithetical to the process of what modern democracy should define as liberty. The sooner we are without it, the better.
Religious leaders need to be held accountable for their ideas.
There is a maxim about the universe which I always tell my students: That which is not explicitly forbidden is guaranteed to occur.
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.
Lack of comfort means we are on the threshold of new insights.
You are all stardust.
It really is the most poetic thing I know about physics: you are all stardust.
Teaching and writing, to me, is really just seduction;
you go to where people are and you find something that they're interested in and you try and use that to convince them that they should be interested in what you have to say.
Our modern conception of the universe is so foreign to what even scientists generally believed a mere century ago that it is a tribute to the power of the scientific method and the creativity and persistence of humans who want to understand it.
We all trust each other to some extent.
We have to rely on experts to some extent, but we should learn to be sceptical.
At the heart of quantum mechanics is a rule that sometimes governs politicians or CEOs-as long as no one is watching, anything goes.
In 5 billion years, the expansion of the universe will have progressed to the point where all other galaxies will have receded beyond detection.
Empty space is a boiling, bubbling brew of virtual particles that pop in and out of existence in a time scale so short that you can't even measure them.
Science is only truly consistent with an atheistic worldview with regards to the claimed miracles of the gods of Judaism, Christianity and Islam. Moreover, the true believers in each of these faiths are atheists regarding the specific sacred tenets of all other faiths. Christianity rejects the proposition that the Quran contains the infallible words of the creator of the universe. Muslims and Jews reject the divinity of Jesus.
Keeping religion immune from criticism is both unwarranted and dangerous.
I hope that every [person] at one point in their life has the opportunity to have something that is at the heart of their being, something so central to their being that if they lose it they won't feel they're human anymore, to be proved wrong because that's the liberation that science provides. The realization that to assume the truth, to assume the answer before you ask the questions leads you nowhere.
You couldn't be here if stars hadn't exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution - weren't created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way they could get into your body is if the stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.
The ultimate goal of physicists is to arrive at an equation that explains everything and could fit on a t-shirt. That may happen but the t-shirt would have to be 10-dimensional.
Metaphysical speculation is independent of the physical validity of the Big Bang itself and is irrelevant to our understanding of it.
A universe without purpose should neither depress us nor suggest that our lives are purposeless. Through an awe-inspiring cosmic history we find ourselves on this remote planet in a remote corner of the universe, endowed with intelligence and self-awareness. We should not despair, but should humbly rejoice in making the most of these gifts, and celebrate our brief moment in the sun.
My area of research is something that in all fairness has no practical usability whatsoever and the thing is I'm often asked to apologize for that. It is interesting to me that people ask 'what's the point of doing that if it's not useful?' But they never ask that, or do they very rarely ask that about art or literature or music. Those things are not gonna produce a better toaster.
The fact is that people would rather cling when they're afraid of something to a priori beliefs than rather open their minds about it.
Most people don't base their morality on religion in spite what they say.
If you ask people, "If you didn't believe in God, would you go out and kill your neighbour?" Most people will say, "No".
If we wish to draw philosophical conclusions about our own existence, our significance, and the significance of the universe itself, our conclusions should be based on empirical knowledge. A truly open mind means forcing our imaginations to conform to the evidence of reality, and not vice versa, whether or not we like the implications.
Of course, supernatural acts are what miracles are all about.
They are, after all, precisely those things that circumvent the laws of nature. A god who can create the laws of nature can presumably also circumvent them at will. Although why they would have been circumvented so liberally thousands of years ago, before the invention of modern communication instruments that could have recorded them, and not today, is still something to wonder about.
I like to say that while antimatter may seem strange, it is strange in the sense that Belgians are strange. They are not really strange; it is just that one rarely meets them.
If our species is to survive, our future will probably require outposts beyond our own planet.
