We all measure our experience in space-time differently. That’s because space-time isn’t flat — it’s curved and it can be warped by matter and energy. … And for astronauts on the International Space Station that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.

Can the Earth fall out of orbit?
The escape velocity of the Earth is about 11 km/s. In other words anything on the Earth’s leading side would fly off into space continuing along the Earth’s orbital path around the sun. Anything on the trailing side would be pulverized against the Earth. It would be a horrible gooey mess.
