We know there is gravity because apples fall from trees. We can observe gravity in daily life. If we could throw an apple to the edge of the universe, we would observe it accelerating.
Adam Riess
Einstein wrestled with a problem back before we even knew the universe was expanding, and he was looking for a way to keep the universe from collapsing. And so he discovered, in his theory of gravity, something like this dark energy - he called it a cosmological constant - could play this role, pushing things away.
One of the most exciting things about dark energy is that it seems to live at the very nexus of two of our most successful theories of physics: quantum mechanics, which explains the physics of the small, and Einstein's Theory of General Relativity, which explains the physics of the large, including gravity.
I have always given priority to the gravity of the roles I do.
Aishwarya Rajesh
At one-sixth gravity in that suit, you have to move in a different way.
Alan Bean
You will find truth more quickly through delight than gravity. Let out a little more string on your kite.
Alan Cohen
I am not aware of any sensible theory of how classical gravity could interact with quantum matter, and I can't imagine how such a theory might work.
Alan Guth
From a theoretical point of view, it is very hard to imagine how gravity could avoid being quantized.
Do I believe, for example, that by using magic I could fly? No. How would you get around gravity? Impossible. Do I believe that I might be able to project my consciousness into a very, very vivid simulation of flying? Yeah. Yes, I've done that. Yes, that works.
Alan Moore
We wanted to be in great shape, we wanted to be able to cope with zero gravity, we wanted to be able to cope with accelerations and decelerations and so on. So all of us trained so that we were probably in the best physical condition we had ever been in up until that point.
Alan Shepard
We really just didn't realize the diversity of planetary types in our solar system. Pluto looked like a misfit because it was the only one we saw. And just as a Chihuahua is still a dog, these ice dwarfs are still planetary bodies. They're large enough to make themselves round by self gravity, and they surely pass the test of planethood.
Alan Stern
Of course Pluto is a planet: It's massive enough to have its shape controlled by gravity rather than material strength, which is the hallmark of planethood.
You can't blame gravity for falling in love.
Albert Einstein
With the finale episode of 'Gravity Falls' our job as storytellers is to finish all the things we've started.
Alex Hirsch
Gravity Falls' has so much inspiration that comes from 'Twin Peaks,' the idea of Agent Cooper being the one to drive Dipper and Mabel home made me feel like, yeah, they're going to be all right.
Gravity Falls' was a labor of love, but like all labor it could be painful at times.
I always designed 'Gravity Falls' to be a finite series about one epic summer-a series with a beginning, middle, and end.
Gravity Falls' is a riddle wrapped in an enigma tucked in a mystery deep-fried in a conundrum slathered in hickory-smoked puzzle sauce.
A lot of the fun of 'Gravity Falls' comes from the secrecy surrounding the plot. We want fans to be able to guess and speculate, to be surprised by twists and be engaged when they get things right.
It's always fun to write the little bit of TV that the characters watch in 'Gravity Falls,' because it's a perfect place to poke fun at the media.
Gravity Falls' didn't just appear overnight - every spooky cave and moss covered tree was created by a team of brilliant artists.
Gravity Falls' normally follows very particular rules: we start out in reality close to the world as we know it, usually one magical element presents itself, and then it's essentially vanished or hidden back to where it came from by the end of the 20 minutes.
It's weird because we live in this age of reboots. Everything is getting rebooted: 'The X-Files,' 'Twin Peaks.' We have shows like 'Gravity Falls' that were inspired by these shows, that are now ending and being followed up by reboots of the shows that inspired them.
We passed a sign for Boring, Oregon. We never went there, but I was positively enchanted with the idea that there was a town called Boring. 'Gravity Falls' is partially from what I imagine Boring might be like. Or maybe the opposite of Boring, Oregon, would be 'Gravity Falls.'
I always thought, if I was gonna make a kids show, I would want to make something that my own 12-year-old self would love. So, I put all that in a blender and stewed it together to create 'Gravity Falls.'
Gravity Falls' is a very hard show to produce.
I will say this: 'Gravity Falls' is a show about mystery, that itch you get when you're curious. That itself is a really cool, inspiring thing.
Gravity Falls' is a show about mysteries and magic but first and foremost it's a show about characters.
In swimming at my level it's about control of the small movements. A good ballet dancer floats across the stage, the best sprinters virtually abolish gravity. All motion occurs in the right direction.
In 'Gravity,' nearly everything is a metaphor for the main character. The way I tend to approach a film is that character and background are equally important; one informs the other. Here, Sandra Bullock is caught between Earth and the void of the universe, just floating there in between. We use the debris as a metaphor for adversity.
I have to say, 'Gravity' is better in 3-D, even though in 2-D the quality of the picture is better. But the 3-D is better.
Experiencing this film in 2-D is only getting about 20 percent of the experience of 'Gravity.'
Dramatically, the moment in 'Gravity' that was hardest to nail down is when Ryan is in the Soyuz capsule and she realizes that she's out of fuel. That's when the character's arc gets defined.
As a 22-year Army Veteran who served in Operations Desert Storm and Iraqi Freedom, and as a Civilian Advisor to the Afghan Army in Operation Enduring Freedom, I understand both the gravity of giving the order, and the challenge of carrying it out.
I've gained a seriousness that has to do with a certain perspective, a gratitude for being able to see the importance of things. And that lends itself a gravity to everything. And that is something that I sort of carry as a weight but a good weight inside of me.
I'm looking for a Justice who appreciates the awesome responsibility that she will be given, if confirmed. A Justice who understands the gravity of the office and who respects the very different roles that the Constitution provides for each of the three branches of government.
How do you observe something you can't see? This is the basic question of somebody who's interested in finding and studying black holes. Because black holes are objects whose pull of gravity is so intense that nothing can escape it, not even light, so you can't see it directly.
Gravity wins over all other known forces.
Curiously, a principle affects your life whether you are aware of it or not. For instance, the principle of gravity was working long before the apple ever fell on Newton's head. But once it did, and he understood it, then we as a society were free to harness this principle to create, among other things, airline flight.
Designing a station with artificial gravity would undoubtedly be a daunting task. Space agencies would have to re-examine many reliable technologies under the light of the new forces these tools would have to endure. Space flight would have to take several steps back before moving forward again.
The reason space missions need artificial gravity is clear: humans simply did not evolve to live in zero gravity.
I don't love the fact that gravity is winning as I get older, but there's also a calmness that comes with it, which I'm secretly enjoying.
The most uncomfortable thing about going to space is coming home. It's a little strange to get used to gravity again.
Gravity is a really heavy force and you don't realize how heavy it is until you haven't felt it for six and a half months.
We have people being a little uncomfortable in their life on Earth with finances and so on, so Science Fantasy or Science Fiction allows people to think that there are possibilities beyond the gravity of our planet.
We buy a copy of 'Gravity's Rainbow,' say, and we carry our copy home. We open it; we fall into it. And it is here that the word 'copy' fails. Because what I experience when I read 'Gravity's Rainbow,' or 'Beloved,' or 'The Moviegoer,' is not at all a 'copy' of what you experience when you read the same novel.
I always found it satisfying that gravity was described by Einstein's geometric theory of general relativity.
Opinion is like a pendulum and obeys the same law. If it goes past the centre of gravity on one side, it must go a like distance on the other; and it is only after a certain time that it finds the true point at which it can remain at rest.
In many ways, string theory attempts to go beyond Einstein's dream... an all-encompassing description of nature that works at large distances where gravity becomes important as well as small distances where quantum mechanics is important.
One of the main successes of string theory is that it has been able to unify the general theory of relativity, which describes gravity, and quantum mechanics.
