Black holes in quantum state break the limits of the strange
They would help to achieve a unifying theory between general relativity and quantum mechanics, capable of explaining the nature of the Universe at all its…
Supernova explosions reveal tiny details about dark energy and dark matter
More than two decades of ongoing analysis of supernova explosions strongly supports modern cosmological theories and reinvigorates efforts to answer fundamental questions. Astrophysicists have performed…
This is how they have achieved quantum teleportation that opens the way to the internet of the future
They show that the teleportation of quantum bits in a network without cables or waves is possible, with a view to a safer internet As…
Mystery object may be a ‘strange star’ made of quarks, scientists say
A relatively small, dense object disguised within a cloud that exploded a few thousand light-years away challenges our understanding of stellar physics. By all accounts,…
