Gravity And Unknown Factors
The reason Einstein’s theory of general relativity works well in lower energy calculations and standard quantum techniques but not in higher energies and scales (like a black hole), could be because certain key features or ingredients of gravity are yet unknown to us, and are therefore missing from the famous theory.

Einstein, Symmetry and the Future of Physics
Insights of Albert Einstein
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...
Some changes don't change anything
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.
Relationships over things
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.

Time Travel: Theories, Paradoxes & Possibilities
Time Travel
The Science Fiction’s holy grail, Time Travel has been a popular topic in various books, movies and TV series for decades.
Time Travel is the ability to ‘travel’ between two different point...
Understanding Time
According to physicist Albert Einstein, time is not a constant phenomenon as it appears, but is an illusion, and can vary from different vantage points.
Space is three-dimensional, and Time, according to the famous physicist, is the fourth dimension. It also speeds up or slows down, so is actually subjective, as stated in his Theory Of Special Relativity.
Space-Time
Einstein's theory of general relativity says that Time can be bent, stretched and squeezed, and the four-dimensional fabric with a huge mass creates a dimple, or bending of Space-Time, causing gravity.
This effect of time dilation is proven using GPS satellite technology in space, making astronauts not only travel space but in a slightly different time than the earthlings.

Teleportation: will it ever be a possibility?
Teleportation
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...
Teleportation is possible in principle
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.
Teleporting humans
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.
