Quotes About Astrophysics

Neutronium is so dense that a chunk the size of a thimble would weigh about 100 million tons.

My mom studied biology and my dad studied chemistry and some physics and he is a physician, but he had a very strong interest in astronomy and astrophysics and exploration in general.

As an astrophysicist, my research work involves mapping dark matter, the elusive substance that accounts for about a quarter of our universe.

There is in space a small black holeThrough which, say our astronomers,The whole damn thing, the universe,Must one day fall. That will be all.

If you want to see a black hole tonight, tonight just look in the direction of Sagittarius, the constellation. That's the center of the Milky Way Galaxy and there's a raging black hole at the very center of that constellation that holds the galaxy together.

Black holes destroy any objects that happen to fall victim to their gravitational pull.

we currently live in a region—300 light-years across—called the Local Bubble, which is a vacuum-like domain with very low hydrogen density within the interstellar medium in the Orion Arm of the Milky Way.

better not to do than to do, better to meditate than to act, better his astrophysics, the threshold of the Unknowable, than my chemistry, a mess compounded of stenches, explosions, and small futile mysteries

laws of physics as we know them break down somewhere between the time of the Big Bang and time zero.

A black hole with the mass of the Sun would take 1066 years for this to occur, even if it never swallowed any outside matter along the way. A black hole with the mass of a galaxy will evaporate in 1099 years, and even a hole containing the mass of a supercluster of galaxies – the biggest ever likely to form – will be gone in 10117 years. That

spacetime is flat, that about 5 per cent of the mass of the Universe is in the form of baryons (including bright stars and gas and dust), some 27 per cent is in the form of cold dark matter, and 68 per cent is in the form of the lambda field, also known as dark energy.

In the early 1990s a PhD student by the name of Zhihong Xia proved that there is a way to configure five planets such that when you let them go, the combined gravitational pull causes one of the planets to fly off and reach an infinite speed in a finite amount of time.

The brain is a three pound mass you can hold in your hand that can conceive of a universe a hundred-billion light-years across.

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

Finding something spherical in space indicates that you have found a place where gravity has taken over.

I know that the molecules in my body are traceable to phenomena in the cosmos. That makes me want to grab people on the street and say: 'Have you HEARD THIS?

Recent discoveries about the primeval cosmos oblige us to accept that the expanding universe has been set up in its motion with a cooperation of astonishing precision.

The hostile force! The reasone the barrier was established. "Astrophysics, do we know what's causing that?" "No, sir," Bruno said cheerfully. "Not a clue".
