Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.
Does space have a end?
-
-
No, they don’t believe there’s an end to space. However, we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists.
Would a body decompose in space?
-
Inside a spacesuit, rigor mortis would still occur since it is the result of the cessation of bodily functions. And bacteria from the gut would still devour the soft tissues. But these bacteria need oxygen to function properly and so limited supplies of air would significantly slow down the process.
-
In space we can assume that there would be no external organisms such as insects and fungi to break down the body, but we still carry plenty of bacteria with us. Left unchecked, these would rapidly multiply and cause putrefaction of a corpse on board the shuttle or the ISS.
Is there a color in space?
-
It turns out that if the universe was infinitely large and infinitely old, then we would expect the night sky to be bright from the light of all those stars. Every direction you looked in space you would be looking at a star. Yet we know from experience that space is black!

Space emits many wavelengths of light – including a lot of blue and red light that our human eyes can see – but also ultraviolet light, gamma rays, and X-rays, which remain invisible to us.

-
In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.
Are space photos coloured?
-
Are the colors in space photos real? No, they are not. The Webb telescope sees in red. It’s up there specifically to detect infrared light, the faintest and farthest light in the cosmos.
What happens if an astronaut dies in space?
-
On short missions, it’s likely the body would be brought back to Earth. The body would need to be preserved and stored to avoid contamination of the surviving crew.

What is beyond our universe?
-
the universe contains all solar systems, and galaxies. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy, and the universe is made up of all the galaxies – billions of them.
-
The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.
Is Laika the dog still in space?
-
Laika, a Moscow street dog, became the first creature to orbit Earth, but she died in space.
What color is blood in space?
-
This leaves only high-energy blue light to be reflected from our maroon veins. So, if you cut yourself in space, your blood would be a dark-red, maroon color.

We can’t smell space directly, because our noses don’t work in a vacuum. But astronauts aboard the ISS have reported that they notice a metallic aroma – like the smell of welding fumes – on the surface of their spacesuits once the airlock has re-pressurised.
