Specifically, no... but there are scientific theories out there that surely point to a possibility of proving that spirits exist. The majority of Theoretical Physicists, particularly Stephens Hawkings believe in something called String Theory or M-Theory. These two theories suggest that we live in a 10 or 11-dimensional world. Parts of these theories can be proven mathematically, and the rest will most likely be proven within the next 50-80 years! The human brain can only see in 3 dimensions (length, width, and depth). However, everyone knows that there are actually 4 (the 4th being time). Einstein proved that we live in 4 dimensions (called Relativity) eighty years ago, however it’s just now being widely accepted and taught in schools. 80 years later!
So just think about the possibilities! We only have proven four… but imagine what just one or two more might look like, let alone eleven! It was Einstein who said that we only use around 10% of our brains. This would explain why the majority of humans cannot see ghosts. They can’t see into these “other” dimensions because they’re not using the part of their brains that allow them to. Spirits live on different dimensions or planes of existence. Look at it like this… our bodies aren’t who define us. They are just our vessels. Think of the brain (or soul) like the pilot and our bodies are just the planes we move around in. If we were able to use 100% of our brain, I'd bet that we definitely wouldn't need our bodies to exist. The same goes for spirits and ghosts. They can live and move around freely because they exist in a different dimension. Which I'm assuming, is where we go when our bodies die (or when the engine shuts down)! :)
