The question is irrelevant, since sounds cannot be transmitted through space.
Photons do not experience the passage of time from their perspective as they travel at the speed of light. This means they do not travel forwards or backwards through time. Time does not apply to particles moving at the speed of light.
No, I could not.
You would see opening and shutting arteries and pumping moving blood
It Could Depend. But it could be possible.
That's simple. They could look through a telescope and see some planets near the earth, but not all. Astronauts travel in space and study them.
Yes, a black hole could travel through space.
sound cant travel on an asteroid because it has no atmosphere. it could travel through it.
There are many places where one could get travel insurance if they were pregnant. The best place where one could get travel insurance would be through a travel agency.
The material through which waves travel is called a medium. This could be a solid, liquid, or gas.
Sound (and vibration) are a wave system of sequential compressions and rarefactions of a material. These waves are mechanical and do need a substance through which to travel. They cannot travel through a vacuum.
One could find about holidays to Tunisia through a travel agent. Newspapers often have a travel section where one could find more information or through the Tunisia website itself.
Not with the technology we have right now.
Sound is a pressure wave. Objects that "allow" sound to travel through them could be called wave guides.
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.
It is because light can travel through space that Earth can get sunlight. Without sunlight life on Earth could not exist.
A combination of train through the Channel tunnel and further land travel. You could go by a ferry across the English Channel. You could fly to a nearby airport.
No, sound waves require a medium to travel through. The medium could be a solid, liquid, or gas, but they cannot travel through a vacuum because there are no particles to transmit the vibrations that carry the sound.
