Does space have an end?
The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).

How do rockets take off?
Rockets take off by burning fuel. Burning fuel produces gas as a byproduct, which escapes the rocket with a lot of force. The force of the gas escaping provides enough thrust to power the rocket upwards and escape the the force of gravity pulling it back to Earth. Simple!
How many dead bodies are in space?
No dead bodies. All space accidents have occurred during either launch or reentry/landing. The only deaths to occur in space were the three-man crew of the Soyuz 11 whose descent capsule depressurized during descent (and, with the crew not wearing spacesuits like they do now, they died as a result).
Do we age faster in space?
Flying through outer space has dramatic effects on the body, and people in space experience aging at a faster rate than people on Earth. … These studies showed that space alters gene function, function of the cell’s powerhouse (mitochondria), and the chemical balance in cells.
Is it true that 1 hour in space is 7 years on Earth?
Answer: The time-dilation effect of Einstein’s relativity has nothing to do with space. The faster you’re moving, the slower time goes for you. So if you were on some planet moving extremely fast through space, like in the movie Interstellar, then you could miss 7 years on Earth every hour.
Will the universe ever end?
Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze. If the expanding universe could not combat the collective inward pull of gravity, it would die in a Big Crunch, like the Big Bang played in reverse.
