You would see the moon.
Because it is a gas giant and doesn't have a surface that you could land on, you could just orbit it and observe it from space, which would be a fascinating thing to do. You could land on some of its moons and explore them and observe Jupiter from them.
if the plants could walk they will go to a place where all that they need is there
it would get blown up or sent into space (lost)
If the sun's radiation could not travel through space, then the Earth would be a cold, dark, frozen rock, and nothing would have ever happened on it.
Yes you would need a first aid box in space.
Space was probably white around a million years after the Big Bang - the birth of the Universe, when the background radiation was at a very high temperature. Now the universe has expanded and cooled down, so the background radiation is at a lower temperature and does not appear as visible light but as faint microwave radiation. If space was white we could not survive those conditions to observe it.
you would die
It would be ground to smaller pieces by the powerful forces in the hole, until it could be enveloped. Though this would only happen in the presence of a star, and to my knowledge, we have yet to observe a collision of this type.
you would not be able to breathe
Both are facing the unknown. We did not know what could happen in space. Sailors in the 1400s did not know what would happen sailing west.
You can't see "space". You can see objects in space, but space itself is not visible.If you did wish to observe objects in space, a telescope would help you to do so.
Of course not. Even if our Sun was going to go supernova, which it won't. There would still be a delay of 8.333 minutes for the light to reach us. Obviously - if you were right next to it, you could eliminate the delay, but you would be unable to observe it, as you would become part of the supernova instantly.
