So, this is a difficult question, and in general it is meaningless. After all, we will die immediately and we will not succeed. But the objects that went there had a strange metallic smell.
Everything is described in detail on the site kristadius.ru, namely in this article: What if you smell the cosmos ?! A lot about the sense of smell ...
I advise, I liked it)
There is an option. It is clear that space is huge, but it contains a mass of molecules. It is a delusion that there is a complete vacuum in space. Everything is soooooooo very thin. Therefore, to imagine how space smells, it is enough to remember how various gases smell. The only problem is that you can't smell space like that if you don't compress it. Although, perhaps, black holes are the noses of such sooooo curious subscribers of the site)
There are two sides of the answer to this question: 1) At the moment, it is generally accepted that the Universe and all outer space, respectively, has no smell. 2) Is this possible? At the moment, definitely not, because we are all we understand what will happen when a person tries to taste the smell of the Cosmos: the irony is that there is nothing to breathe, lol. But your blood does not know this. It circulates through your lungs to pick up more O2 and continues on its way. Your heart continues to beat and the oxygen-deprived blood circulates throughout your body. In particular, it goes to the brain. Ah, and you will also lose consciousness from a lack of air, so you will definitely not smell the smells. ! BUT! If you are especially stubborn, there is one right option: when you go into outer space For a walk without a spacesuit, just hold your breath. Your lungs and airways are not designed to contain atmospheric pressure in a vacuum, so if you hold your breath, you will face the same problem that divers face when climbing too quickly to the surface: ruptured lungs. So, in addition to excruciating pain, a metallic taste of your blood will come to you, and, as you know, due to the taste and characteristics of our body, you will also feel a pungent metallic smell. But, as for me, the pleasure from this is so-so.
