The Metaphysics of Teleportation
Even if science is able to teleport humans across large distances, would the teleported human really be the same person or just an exact replica? What would happen to the soul?
Every Wednesday, Michio Kaku will be answering reader questions about physics and futuristic science. If you have a question for Dr. Kaku, just post it in the comments section below and check back on Wednesdays to see if he answers it.
Today, Dr. Kaku addresses a question posed by Matthew Miossec: If quantum teleportation could teleport a whole human, would that transported human really be the same person or just an exact copy?

Universities claim to prepare students for the world. How many actually do it?
- Many university mission statements do not live up to their promise, writes Ben Nelson, founder of Minerva, a university designed to develop intellect over content memorization.
- The core competencies that students need for success—critical thinking, communication, problem solving, and cross-cultural understanding, for example—should be intentionally taught, not left to chance.
- These competencies can be summed up with one word: wisdom. True wisdom is the ability to apply one's knowledge appropriately when faced with novel situations.
This is what the world will look like, 250 million years from now
To us humans, the shape and location of oceans and continents seems fixed. But that's only because our lives are so short.
SpaceX's momentous Crew Dragon launch is a sign of things to come for the space industry, and humanity's future.
- SpaceX was founded in 2002 and was an industry joke for many years. Eighteen years later, it is the first private company to launch astronauts to the International Space Station.
- Today, SpaceX's Crew Dragon launched NASA astronauts Bob Behnken and Doug Hurley to the ISS. The journey will take about 19 hours.
- Dylan Taylor, chairman and CEO of Voyager Space Holdings, looks at SpaceX's journey from startup to a commercial space company with the operating power of a nation-state.
A new study may help us better understand how children build social cognition through caregiver interaction.
Researchers at UT Southwestern noted a 47 percent increase in blood flow to regions associated with memory.
