Does time feel the same in space?

Time is measured differently for the twin who moved through space and the twin who stayed on Earth. The clock in motion will tick more slowly than the clocks we’re watching on Earth. If you’re able to travel near the speed of light, the effects are much more pronounced.

What would happen if an astronaut took off his helmet?

Without a helmet, and your own personal Earth-like atmosphere surrounding you, you’ll be exposed to the hard vacuum of space. Within a moment, all the air will rush out of your lungs, and then you’ll fall unconscious in about 45 seconds. Starved for oxygen, you’ll die of suffocation in just a couple of minutes.

What would happen to your body if you died in space?

10 seconds of exposure to the vacuum of space would force the water in their skin and blood to vaporize, while their body expanded outward like a balloon being filled with air. Their lungs would collapse, and after 30 seconds they would be paralyzed—if they weren’t already dead by this point.
