Neil deGrasse Tyson Quotes

In five billion years, the sun will expand and engulf our orbit as the charred ember that was once Earth vaporizes. Have a nice day

I think about the cosmic snowball theory. A few million years from now the sun will burn out and lose its gravitational pull. The earth will turn into a giant snowball and be hurled through space. When that happens it won't matter if I get this guy out.

Well, my friend, this earth will one day be that cold corpse; it will become uninhabitable and uninhabited like the moon, which has long since lost all its vital heat.

Some 5 billion years from now, there will be a last perfect day on Earth... then the sun will begin to die, life will be extinguished, the oceans will boil and evaporate away.

Look at the stars, how they shine and glow, some of the stars died a long time ago. Still they shine in the evening skies for you see, love like starlight never dies

If we are still here to witness the destruction of our planet some five billion years or more hence, then we will have achieved something so unprecedented in the history of life that we should be willing to sing our swansong with joy - Sic Transit Gloria Mundi.

when happiness makes a guest appearance in one's life,it's important to make the most of it.It may not stay around for long and when it has gone wouldn't it be terrible to think that all the time one could have been happy was wasted worrying when the happiness would be taken away.

I have had a long, long life full of troubles, but there is one curious fact about them-nine-tenths of them never happened.

Worry lives a long way from rational thought."---Self

As a planet, we are at risk of destruction (for example, gradually by the warming of the planet; or rapidly, by nuclear war or a pathogen that gets out of control). And these threats require us to work together, and not just to announce our diversity.

In the primary debates for the 2016 election, every single Republican candidate was a climate change denier, with one exception, John Kasich - the "rational moderate" - who said it may be happening but we shouldn't do anything about it. For a long time, the media have downplayed the issue.

China likes the idea of sovereign rights when it comes to organizing their politics as they see fit, and their economics. But they may grudgingly come to understand certain things differently in the area of climate or disease. China is a country fairly integrated into the world. Yet China is uncomfortable with this idea because they worry it will constrain their freedom, politically and economically, to do what they believe they need to do to maintain political stability and cohesion.

A single lifetime, even though entirely devoted to the sky, would not be enough for the study of so vast a subject. A time will come when our descendants will be amazed that we did not know things that are so plain to them.

If you think about your and my grandchildren, this is what really worries me. I don't want them - if I'm still alive by then - to say, 'Why didn't you do something about it?', when you could have done.

If they survive, today's children will inherit a world that our fathers and grandfathers have ravaged, where the seas are acidic cesspools that the whales have fled, where rain forests are Indian memories never to return, and where human greed has plundered Mother Earth's innards and turned human genes into factories for profit. They will inherit a diminished planet where fresh water is increasingly rare, and where fresh air is a commodity... We live in a world that fears and hates its young. How else can one explain the bequest of such a foul, polluted, and hollow inheritance?

The climate dice are now loaded. Some seasons still will be cooler than the long-term average, but the perceptive person should notice that the frequency of unusually warm extremes is increasing. It is the extremes that have the most impact on people and other life on the planet.

Humanity is facing a very big, slow, long, drawn-out threat, and that is to do with the way the weather is changing and the size of the population.

Earth, earthriding your merry-go-roundtoward extinction,right to the rootsthickening the oceans like gravy,festering in your caves,you are becoming a latrine.

I think people who worry about planetary health on geological scales are totally misguided, that's not the point at all.

time is a tree (this life one leaf) but love is the sky and i am for you just so long and long enough

We are in the midst of the 6th largest extinction event in the history of the plant and the first caused by human action.

The long summer was over. For ages a tropical climate had prevailed over a great part of the earth, and animals whose home is now beneath the Equator roamed over the world from the far South to the very borders of the Arctics ... But their reign was over. A sudden intense winter, that was also to last for ages, fell upon our globe.

The Arctic and the Antarctic are melting quickly. We may have waited too long to get started. But this is a day for optimism because the battle is fully joined, and the idea that big oil is unbeatable is no longer true.

Perhaps someday in the distant future, dinosaurs may once again rule the Earth. If they ever learn to watch the stars, then maybe they will find our ruins in the sky.

When you look at Earth from that one picture, the one from space, it's really a rather attractive thing. I have nothing against the planet per se. I root for the big comet or asteroid as a way of cleansing the planet. The comet or asteroid 65 million years ago is probably what gave us our opening to replace the reptiles. The greatest entertainment I have in my life is chronicling internally, not necessarily for the public, the slow dissolution of order.
