It was gravity which pulled us down




















You hurt the ones that I love best and cover up the truth with lies. One day you'll be in the ditch, flies buzzin' around your eyes, Blood on your saddle. Idiot wind, blowing through the flowers on your tomb, Blowing through the curtains in your room.

Now everything's a little upside down, as a matter of fact the wheels have stopped, What's good is bad, what's bad is good, you'll find out when you reach the top You're on the bottom. I noticed at the ceremony, your corrupt ways had finally made you blind I can't remember your face anymore, your mouth has changed, your eyes don't look into mine.

The priest wore black on the seventh day and sat stone-faced while the building burned. I waited for you on the running boards, near the cypress trees, while the springtime turned slowly into autumn.

I can't feel you anymore, I can't even touch the books you've read Every time I crawl past your door, I been wishin' I was somebody else instead. Down the highway, down the tracks, down the road to ecstasy, I followed you beneath the stars, hounded by your memory And all your ragin' glory. I been double-crossed now for the very last time and now I'm finally free, I kissed goodbye the howling beast on the borderline which separated you from me. You'll never know the hurt I suffered nor the pain I rise above, And I'll never know the same about you, your holiness or your kind of love, And it makes me feel so sorry.

It holds down our atmosphere and the air we need to breathe. Gravity is what holds our world together. Gravity is slightly stronger over places with more mass underground than over places with less mass. Areas in blue have slightly weaker gravity and areas in red have slightly stronger gravity.

GRACE detects tiny changes in gravity over time. These changes have revealed important details about our planet. What Is Gravity? What else does gravity do? Gravity in our universe Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. What is a black hole? More about gravity! What is a gravitational wave? What is a barycenter? If you liked this, you may like: What Is a Barycenter? What Is a Black Hole? What Is a Gravitational Wave? The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetime.

That curvature is what you feel as gravity. Spacetime is exactly what it sounds like: the three dimensions of space — length, width and height — combined with the fourth dimension — time. Using some very brilliant math, Einstein was the first person to realize that the laws of physics work in a universe where space and time are merged together. What this means is that space and time are connected — if you move really fast through space, time slows down for you compared to someone who is moving slowly.

This is why astronauts — who are moving very fast in space — age a tiny bit more slowly than people on Earth. Remember, gravity is the idea that objects in the universe are attracted to each other because spacetime is bent and curved. When Einstein came up with general relativity, he showed that all stuff in the universe can curve spacetime — in physics terms that stuff is mass and energy. Since your brain usually thinks about the world in three dimensions, it is really hard to think about the four dimensions of spacetime as a single idea.

So to make it easier to visualize, imagine the surface of a trampoline. If there is nothing on it, it is flat. But if you stand on the trampoline, it stretches around your feet and creates a valley with you at the center. If there is a ball on the trampoline, it would roll toward your feet.
