Optical illusions are images that the brain perceives differently than they are. Jackpotjoy shared an incredible illusion to trick your brain “into thinking that the black hole is growing, when in fact it is a still image” and only one in 10 are able to see the black hole stay still.
The colourful optical illusion, formed of black dots and a black oval in the middle, is a completely still image but it appears to move before your eyes.
“The shadowy, faded edges of the black hole make it appear as if the black colour is spreading out as if you were heading into a hole or a tunnel.”
Jackpotjoy explained that according to scientists, this illusion can also cause “your pupils to dilate when you are tricked by the image”.
Only one in 10 people claim the image doesn’t move for them at all.

This can be a normal response to darker surroundings “so your eyes really are tricked into believing you’re entering a black hole,” they explained.
Playbuzz recently created another clever illusion where people have to find a giraffe in 11 seconds.
The giraffe is located in the middle of a colourful illustration formed of many different animals including lions, hippos, elephants and monkeys.
The animals have different colours and are positioned a certain way to confuse people but those with “extraordinary intelligence” will be able to find it in less than 11 seconds.
They explained that scientists still haven’t figured out how the brain and eyes work together to create these illusions.
“We know that information that our eyes gather goes on a long, complicated journey as it travels to the brain. Some of the confusion happens early in that journey,” they added.
PhD student at the University of Queensland Mr Cedric van den Berg explained: “Our eyes and brain speak to each other in a very simple language, like a child who doesn’t know many words.”
However, “most of the time that’s not a problem and our brain is able to understand what the eyes tell it”.
