Loosely quoted from Star Talk Radio:

“It seems to me that science is the only human collaboration that transcends human boundaries. The results you find are independent of what country you come from, what religion you believe in, what government you have. So when you think of what is the future that could possibly unfold in a world that is divided by politics, by religion and by any other reason people give to kill another person for crossing a line in the sand, it tells me that the only hope we have is to search for the truth that we find through the research conducted by science.”

“If you stare at nothing for long enough, something will appear”

– Lawrence Krauss

 

The idea that something can’t come from nothing has been rendered obsolete by quantum mechanics. Just as Krauss says, if you observe a space of absolutely nothing (a vacuum), particles will appear and disappear frequently from the nothingness (quantum fluctuations). I mentioned more on this in my post about how the universe can create itself out of nothing.

Just finished watching a discussion between Richard Dawkins and Lawrence Krauss. There were many profound things said, and many obvious ones that unfortunately still need to be said, but this quote particular gave me a good laugh.

In regards to theology not being a real subject, I put this challenge out to all theologians. Name me one piece of knowledge theology has contributed to human society in the last 500 years. When I speak to theologians, they always seem to answer “well, what do you mean by knowledge?”, but when I talk to chemists, physicists and medical doctors, they give me concrete facts straight away.

– Lawrence Krauss.

In 5 billion years, the expansion of the universe will have progressed to the point where all other galaxies will have receded beyond detection.  Indeed, they will be receding faster than the speed of light, so detection will be impossible.  Future civilizations will discover science and all its laws, and never know about other galaxies or the cosmic background radiation.  They will inevitably come to the wrong conclusion about the universe……We live in a special time, the only time, where we can observationally verify that we live in a special time.

– Lawrence M. Krauss

Just imagine – a day when the skies are completely black at night and no matter how advanced technology gets (if classical physics is right and light speed is the max), they will never know anything about other stars or galaxies. The only evidence that they ever existed would be old stories. Mind blowing stuff.

By the way, I’ve heard a question in response to this quote basically wondering how the galaxies can be receding faster than light speed if light speed is the maximum. The reason is because the receding of galaxies is not “physical” travel through space, but rather it is the expansion of the fabric of space-time. Those familiar with science will understand this. If it helps, imagine two dots on the surface of a balloon. As you inflate the balloon, the two dots move farther apart because the surface of the balloon is expanding, but their physical locations on the balloon is still the “same” (i.e. the dots aren’t moving along the balloon, they’re still where you put them – it’s the surface of the balloon that’s stretching).

Your pain is the breaking of the shell that encloses your understanding. It is the bitter potion by which the physician within you heals your sick self. Therefore, trust the physician and drink the remedy in silence and tranquility.

– Khalil Gibran

I normally don’t get too involved in politics, but this was too awesome to pass up. How could you not vote for such a cool guy? It’s not actually a quote as much as a speech, and I’m sure everyone’s heard it already, but I’ll leave it here as a funny keepsake:

“What professions do all these senators and congressmen have? Law, law, law, law, business, law, law, law … Where are the scientists? Where are the engineers? Where’s the rest of … life?”

– Dr. Neil deGrasse Tyson
