Cosmologists have plenty of ego. How could you not when your job is to deduce what brought the universe into existence?
Are we missing some basic pieces of the universe that once were? What part of the cosmic history book has been marked “access denied”? What remains absent from out theories and equations that ought to be there, leaving us groping for answers we may never find?
Explore the universe for what it is, rather than for what it seems.
In 1994, NASA’s Compton Gamma Ray Observatory detected something as unexpected as the Velas’ discoveries: frequent flashes of gamma rays right near Earth’s surface. They were sensibly dubbed “terrestrial gamma-ray flashes.” Nuclear holocaust? No, as is evident from the fact that you’re reading this sentence.
Some of the water you just drank passed through the kidneys of Socrates, Genghis Khan, and Joan of Arc. Some of the air you just breathed passed through the lungs of Napoleon, Beethoven, Lincoln, and Billy the Kid.
No day before October 10, 1582, actually occurred on the Gregorian calendar for that was when the calendar was implemented officially.
We are not simply in the universe, we are part of it. We are born from it. One might even say that the universe has empowered us, here in our small corner of the cosmos, to figure itself out. And we have only just begun.
Personally, I am quite comfortable with chemicals, anywhere in the universe. My favorite stars, as well as my best friends, are all made of them.
Not only that, this “negative gravity” will ultimately win the tug-of-war, as it forces the cosmic expansion to accelerate exponentially into the future.
Nebulium was simply the signature of ordinary oxygen doing extraordinary things.
For generations, Americans have expected something new and better in their lives with every passing day – something that will make life a little more fun to live and a little more enlightening to behold. Exploration accomplishes this naturally. All we need to do is wake up to this fact.
Since everything warmer than absolute zero radiates heat, detecting infrared at a distance means, in principle, detecting everything.
Noise” includes any unwanted signal that contaminates the target of measurement.
For all we know, the aliens may have tried to get in touch centuries ago and have concluded that there is no intelligent life on Earth. They would now be looking elsewhere. A more humbling possibility is that aliens did become aware of the technologically proficient species that now inhabits Earth, and drew the same conclusion.
Brick walls are opaque to our eyes, but to microwaves those walls are transparent, which is why we can talk on our cell phones while indoors.
It’s all you have when you realize you are not entirely in control of outcomes. But without it, how else do we cope with the challenges of life?
The former pair offered physics and logic; the latter offered primarily politics and fear plus a.
Einstein himself, acutely aware of the world’s newfound capacity for annihilation, said in a 1949 interview in Liberal Judaism, “I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.
So by looking in X-rays, you are seeing aspects of nature which we did not even suspect existed but which are very important in the formation, evolution, and dynamics of the structures in the universe.
But because the particle shower moves so fast relative to us and our detectors on Earth’s surface, the muons experience the passage of time more slowly than we do.
