Firstly, the intense gravitational pull of a black hole would cause anything that falls in to be ‘spaghettified’. This is where the immense gravitational pull is so strong that the force is much stronger at the base than the top. For example, if you were travelling feet first into a black hole, the gravity be so strong you would be stretched out to a point where you would just be a long stream of atoms.
However, if you were to travel there with another person and they remained on a spaceship, they would never actually see you fall into the black hole.
Instead, they would see you become frozen on the edge of the black hole, with your appearance becoming redder and redder.
This is because the gravitational of the black hole stretches the light reflecting off your body meaning the wavelengths are longer – the colour with the longest wavelength is red.
Emma Osborne, an astrophysicist from the University of Southampton, told an audience at New Scientist Live: “Your spaceship mate would see you get stretched out, but they would never actually see you fall into the black hole.
“Instead, you will start to change colour. You will turn redder and redder and redder until ultimately an image is frozen on the edge of the black hole of you from the view of the people in the spaceship.
“The reason that happens is that light interacts with the gravitational field, so any light that is reflecting off you, as it travels from your body towards the spaceship, it gets stretched out.
“As the wavelength increases, you actually end up getting to the redder end of the light scale so that is why it turns red.
“The reason why it freezes in time is because space and time are effected by gravity. So as space gets stretched, time gets stretched – the time passes slower and slower when you are in a gravitational field.”
However, it would almost be impossible in trying to reach a black hole.
The nearest black hole to our planet is located 6,523 light-years away – one light-year is 5.88 trillion miles.
The farthest humans have been from Earth is 248,655 miles (400,171 km) in 1970 as part of NASA’s Apollo 13 mission when the craft swung around the far side of the moon – it took almost three days to get there.
As such, the timescale for the black hole eventually reaching Earth would be billions of years away, by which time the Sun would have likely burned out, and taken Earth with it.
