First things first: the gravitational power of pulling of a black hole would cause pretty much anything to fall into it. That’s where the gravitational pull is so powerful that the force is stronger at the base, and not at the top. Let us take a clear example: if you are traveling with your feet first into a black hole, then the gravity would be so overpowering, that you would be stretched into a long stream of atoms.
But, if you had another person with you, and they were the ones to remain of the spaceship, then they wouldn’t be able to see you fall into the black hole. Instead of that, they would know how you become frozen on the edge of the black hole, becoming redder and redder. This would happen due to the gravitation of the black hole, which would stretch the light which reflects off your body. This also means that the wavelengths are longer. Red is the color with the longest wavelength.
Emma Osborne, from the University of Southampton, has talked to an audience at New Scientist Live and said that the person from the spaceship would see you stretched out, but not actually falling into the black hole. You will start to change the color of your appearance. You will get redder until you get frozen on the edge of the black hole – this is how people from the spaceship will see you. You’re probably asking yourself why is this happening. It’s happening because the light has an impact on the gravitational field. This means that any light that is reflecting off you gets stretched out when it travels from your body to the spaceship. When the wavelength increases, you get redder and redder to the end of the light scale.
