If it is safe!I think it can't
Acording to Universe Sandbox, Earth will leave its orbit around 2600. But no. the sun will envelop Earth before it can leave orbit
1. The universe will keep expanding forever 2. The expansion of the universe will gradually slow down, and the universe will approach a limit in size. 3. The universe will stop expanding and start to fall back in on itself.
In terms of inventions, the telescope would have made it possible to do this.
You had better travel near the speed of light or you will not see much of the universe. Unfortunately travelling near the speed is not yet possible, so you are out of luck.
It is only possible to escape the Earth's gravity by moving away from it at approximately seven miles per second. Seeing as it is very difficult to move at such high speeds by accident, it would not be possible to accidentally leave the atmosphere.
yes, it is possible to tour the universe.
Sound waves do not leave the planet. They cannot travel in the vacuum of outer space
No, the universe is allways expanding, even as you read this!
Sure.... Why not.
yes

its very possible that we are not the only life in the never ending universe so probably not
Yes
Not possible.
Not possible.
No. It wouldn't be possible.
They are not just possible, they are an inevitable consequence of a Universe dominated by gravity.
