A Quote by Carl Sagan

The cosmic calendar compresses the local history of the universe into a single year. If the universe began on January 1st it was not until May that the Milky Way formed. Other planetary systems may have appeared in June, July and August, but our Sun and Earth not until mid-September. Life arose soon after. We humans appear on the cosmic calendar so recently that our recorded history occupies only the last few seconds of the last minute of December 31st.

We humans appear on the cosmic calendar so recently that our recorded history occupies only the last few seconds of the last minute of December 31st.

Carl Sagan

Take the entire 4.5-billion-year history of the earth and scale it down to a single year, with January 1 being the origin of the earth and midnight on December 31 being the present. Until June, the only organisms were single-celled microbes, such as algae, bacteria, and amoebae. The first animal with a head did not appear until October. The first human appears on December 31. We, like all the animals and plants that have ever lived, are recent crashers at the party of life on earth.

Neil Shubin

December is the toughest month of the year. Others are July, January, September, April, November, May, March, June, October, August, and February.

Mark Twain

If you represent the Earth's lifetime by a single year, say from January when it was made to December, the 21st-century would be a quarter of a second in June - a tiny fraction of the year. But even in this concertinaed cosmic perspective, our century is very, very special: the first when humans can change themselves and their home planet.

Martin Rees

While the Copernican principle comes with no guarantees that it will forever guide us to cosmic truths, it's worked quite well so far: not only is Earth not in the center of the solar system, but the solar system is not in the center of the Milky Way galaxy, the Milky Way galaxy is not in the center of the universe, and it may come to pass that our universe is just one of many that comprise a multiverse. And in case you're one of those people who thinks that the edge may be a special place, we are not at the edge of anything either.

Neil deGrasse Tyson

As for September 11, let us not too easily grant the Americans possession of that date on the calendar. Like May 1 or July 14 or December 25, September 11 may seem full of significance to some people, while to other people it is just another day.

J. M. Coetzee

If the age of the Earth were a calendar year and today were a breath before midnight on New Year's Eve, we showed up a scant fifteen minutes ago, and all of recorded history has blinked by in the last sixty seconds. Luckily for us, our planet-mates--the fantastic meshwork of plants, animals, and microbes--have been patiently perfecting their wares since March, an incredible 3.8 billion years since the first bacteria. ...After 3.8 billion years of research and development, failures are fossils, and what surrounds us is the secret to survival.

Janine Benyus

We on Earth have just awakened to the great oceans of space and time from which we have emerged. We are the legacy of 15 billion years of cosmic evolution. We have a choice: We can enhance life and come to know the universe that made us, or we can squander our 15 billion-year heritage in meaningless self-destruction. What happens in the first second of the next cosmic year depends on what we do, here and now, with our intelligence and our knowledge of the cosmos.

Carl Sagan

January cold and desolate; February dripping wet; March wind ranges; April changes; Birds sing in tune To flowers of May, And sunny June Brings longest day; In scorched July The storm-clouds fly, Lightning-torn; August bears corn, September fruit; In rough October Earth must disrobe her; Stars fall and shoot In keen November; And night is long And cold is strong In bleak December.

Christina Rossetti

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.

Lawrence M. Krauss

Humans may or may not have cosmic significance, and if they do, it will be by hitching a ride on the objective centrality of knowledge in the cosmic scheme of things.

David Deutsch

The fearsome blessing of that hard time continues to work itself out in my life in the same way we're told the universe is still hurtling through outer space under the impact of the great cosmic explosion.... I think grace sometimes explodes into our lives like that-sending our pain, terror, astonishment hurtling through inner space until by grace they become Orion, Cassiopeia, Polaris to give us our bearings, to bring us into something like full being at last.

Frederick Buechner

The universe has really never made things in ones. The Earth is special and everything else is different? No, we’ve got seven other planets. The sun? No, the sun is one of those dots in the night sky. The Milky Way? No, it’s one of a hundred billion galaxies. And the universe - maybe it’s countless other universes.

Neil deGrasse Tyson

To assert that the universe has a purpose implies the universe has intent. And intent implies a desired outcome. But who would do the desiring? And what would a desired outcome be? That carbon-based life is inevitable? Or that sentient primates are life's neurological pinnacle? Are answers to these questions even possible without expressing a profound bias of human sentiment? Of course humans were not around to ask these questions for 99.9999% of cosmic history. So if the purpose of the universe was to create humans then the cosmos was embarrassingly inefficient about it.

Neil deGrasse Tyson

Philosophically, the universe has really never made things in ones. The Earth is special and everything else is different? No, we've got seven other planets. The sun? No, the sun is one of those dots in the night sky. The Milky Way? No, it's one of a hundred billion galaxies. And the universe - maybe it's countless other universes.

My life, I realize suddenly, is July. Childhood is June, and old age is August, but here it is, July, and my life, this year, is July inside of July.
