Quotes About Astrophysics

Interplanetary dust," I repeated, liking the feel of the words on my tongue.

We live in a modest system, a galaxy called the Milky Way. If we named every star in the Milky Way and put them in the Hollywood telephone directory and stacked those telephone directories up, we'd have a pile of telephone directories 70 miles high.

Their mutual gravitational attraction will ultimately cause them to collapse inward, in manifest disagreement with an apparently static universe.

the universe could have expanded during this inflationary period by a factor of more than 1028. While this is an incredible amount, it amazingly could have happened in a fraction of a second in the very early universe.

Take the expansion rate of the universe, which is fine-tuned to one part in a trillion trillion trillion trillion trillion. That is, if it were changed by one part in either direction--a little faster, a little slower--we could not have a universe that would be capable of supporting life. ~Stephen C. Meyer, PHD~

I'm an astrophysicist and a professor, so my day job involves manipulating intractable numbers that characterize our universe.

The whole of the hydrogen on the earth might be transformed at once and the success of the experiment published at large to the universe as a new star.

Our galaxy, the Milky Way, is one of 50 or 100 billion other galaxies in the universe. And with every step, every window that modern astrophysics has opened to our mind, the person who wants to feel like they're the center of everything ends up shrinking.

We'll have four different gravitational wave windows open within the next 20 years, and each of them will see something different. We'll be probing the birth of the universe with this. The so-called 'inflationary era' of the universe. We'll be probing the birth of the fundamental forces and how they came into being.

Moreover it is assumed that wormholes only join universes to baby universes, or universes to themselves; there are no wormholes joining different baby universes in this approximation, nor are there allowed to be wormholes which split up into two or more other wormholes.

If you're puzzled by what dark energy is, you're in good company.

I'm a person who's very interested in science and the universe and quantum physics and astrophysics.

Black holes are pretty scary when you ponder them. They seem nihilistic, infinitely destructive on an inconceivable scale, notwithstanding the ideas of Hawking radiation.

We knew from theoretical models that mergers of massive, gas-rich galaxies were more frequent in the past. Now we've found that these mergers are responsible for producing both the nearby obscured quasar population and their distant cousins.

I gained a first class degree in Physics at Imperial College London in 1968 and did research in solid state physics, but did not pursue meteorology matters until gaining an M.Sc. in astrophysics from Queen Mary College London in 1981, after which I investigated and attempted to construct theories of solar activity.

Time can behave like another direction in space under extreme conditions.

The discovery of any kind of life [in Space] at all would be a tremendous watershed moment in biology, as well as all of science.

For example, if the big bang had been one-part-in-a billion more powerful, it would have rushed out too fast for the galaxies to form and for life to begin.

I believe that there are 15,747,724,136,275,02,577,605,653,961,181,555,468,044,717,914,527,116,709,366,231,425,076,185,631,031,296 protons in the universe and the same number of electrons.

Observations indicate that the universe is expanding at an ever increasing rate. It will expand forever, getting emptier and darker.

It's a pity that nobody has found an exploding black hole. If they had, I would have won a Nobel prize.

It turns out that the history of astrophysics is where we perfected time keeping.

Earlier theories ... were based on the hypothesis that all the matter in the universe was created in one big bang at a particular time in the remote past. [Coining the "big bang" expression.]

In some sense, gravity does not exist; what moves the planets and the stars is the distortion of space and time.
