An advanced version of the double-slit experiment by Physicist John Wheeler in the 70s made things even more interesting.
He proved that the mere intention or planning of measuring an outcome of the path of light changes its behaviour as if it knows that a conscious entity is planning to look at the outcome.

Despite the advances in science over the past century, our understanding of nature is still limited. Scientists still don't know what the vast majority of the universe is made up of or how cons...
"Mysterian" thinkers give an important role to biological arguments and analogies.
Late philosopher Jerry Fodor argued that there are bound to be thoughts we are unable to think. Similarly, philosopher Colin McGinn claimed that all minds suffer from "cognitive closure" about particular problems. Just as animals will never understand prime numbers, so human brains are unable to consider some of the world's wonders.
Mysterians present the question of cognitive limits in fixed terms: either we can solve a problem, or we will never be able to.
A possibility that eludes mysterians is one of slowly diminishing returns. We keep slowing down, even as we exert more effort, and there is no point where progress becomes impossible.

Many insights of Albert Einstein are now part of popular imagination: black holes, time warps, and wormholes show up in movies and books.
Less famous, but probably the most revolutionary pa...
The most fundamental aspects of nature stay the same.
For example, Einstein's papers on relativity show that the relationship between energy and mass is invariant, even though energy and mass can take on many different forms.
Even though matter produces energy, the energy-matter content of the universe never changes. Matter and energy are less fundamental than the underlying relationship between them.
We often think of things as the heart of reality. But most often the relationship is more important, not the stuff.
We may think "stuff" like space and time are unchangeable aspects of nature. In reality, the relationship between space and time stays the same.

Teleportation is the idea in which we step into a sort of scanner and instantaneously find ourselves somewhere else.
There are two ways this can'(t) be done: physical deconstruction at x and...
Recently, scientists were able to "teleport" photons to a satellite 300 miles away, using "quantum entanglement." This is where a pair of photons are able to simultaneously share the same state, even when separated by distance. Change the state of one particle, and the other changes too.
Teleportation can have big implications for a new “quantum internet.” It will be faster, more powerful, unhackable.
Scientists are still working out how to teleport photons. Assuming they figure out how to teleport atoms, then molecules, the amount of bits to record and transmit, is unthinkable.
A person is made of an estimated 32 trillion cells. They would require a huge bandwidth and roughly 10th gigawatt-hours of power. Teleporting one person would require using the entire UK power supply for more than a million years and take 4.8 million million years to transfer - that is if you survive the transfer. It would be quicker to walk.
