What are the harms of space?
What Cannot go in the space?
Are black holes in space dangerous?
What is the most deadliest thing in space?
Black holes are obviously terrifying: These crushed remnants of a massive star that exploded as a supernova are so massive that nothing, not even light, can escape its grasp.
What does space smell like?
A succession of astronauts have described the smell as ‘… a rather pleasant metallic sensation … [like] … sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’.
What is the rarest thing in space?
Only 1-in-10,000 galaxies fall into the rarest category of all: ring galaxies. With a dense core consisting of old stars, and a circular or elliptical ring consisting of bright, blue, young stars, the first ring was only discovered in 1950: Hoag’s object.
Why can’t we cry in space?
Astronauts can’t cry the same in space as they do on Earth.
Your eyes make tears but they stick as a liquid ball. In fact, they sting a bit. So — space tears don’t shed.” Unless an astronaut wipes that water away, tears in space can form a giant clump that can break free of your eye, as The Atlantic explained.
What can destroy a black hole?
Eventually, in theory, black holes will evaporate through Hawking radiation. But it would take much longer than the entire age of the universe for most black holes we know about to significantly evaporate.
What can defeat a black hole?
Black holes, the insatiable monsters of the universe, are impossible to kill with any of the weapons in our grasp. The only thing that can hasten a black hole’s demise is a cable made of cosmic strings, a hypothetical material predicted by string theory.

What is the craziest thing in space?
- Black Hole Sagittarius A*: Super-Close but Strangely Quiet. Until recently, black holes seemed to come in only two sizes: either small remnants of collapsed stars or gargantuan beasts with masses of millions or even billions of suns. …

Does space have an 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?
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.
What is the darkest thing in space?
Black holes are the darkest things in our universe because they emit no light whatsoever in any wavelength.
What is the darkest spot in space?
The Darkest Part of the Universe–Boötes Void. In the northern night sky, you can sometimes find a foreleg-shaped cluster of stars known as the Boötes (Greek word for “herdsman”) constellation. In its vicinity, there is an enormous dark space that is 330 million light-years across and shaped like a sphere.
Can a scream be heard in space?
A: Sound is a mecanical wave, which means that it needs substance to travel through, such as air or water. In space, there is no air, so sound has nothing to travel through. If someone were to scream in space, the sound wouldn’t even leave their mouths.
Where do tears go in space?
Since tears on Earth only stream down a person’s face because of gravity’s influence, tears shed in microgravity do not fall. Instead, they pool on the face and could eventually drift off in little droplets that disperse throughout the orbiting science laboratory.
What happens when 2 black holes meet?
It is possible for two black holes to collide. Once they come so close that they cannot escape each other’s gravity, they will merge to become one bigger black hole.
What can destroy a galaxy?
“Black holes form inside their host galaxies and grow inproportion to them, forming an accretion disc which will eventually destroy thehost,” he added. “In this sense they can be described as viral innature.”
Do you fall forever in a black hole?
Of course, no matter what type of black hole you fall into, you’re ultimately going to get torn apart by the extreme gravity. No material, especially fleshy human bodies, could survive intact. So once you pass beyond the edge of the event horizon, you’re done. There’s no getting out.

What is the rarest object in space?
Only 1-in-10,000 galaxies fall into the rarest category of all: ring galaxies. With a dense core consisting of old stars, and a circular or elliptical ring consisting of bright, blue, young stars, the first ring was only discovered in 1950: Hoag’s object.
What is the most violent thing in space?
Thousands of times more energetic than ordinary exploding stars, their visible light as bright as a million galaxies, gamma-ray bursts are the most violent events in the universe, and radiation from one of these events reaches the vicinity of Earth at a rate of about one a day.
Will space go on forever?
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. But nobody knows for sure.
Does space have a smell?
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.
