A recent paper submitted on the journal of Classical and Quantum Gravity inspired an article in Interesting Engineering about it.
Basically until now,
But this new research found a way around this issueresearch into superluminal travel called for massive amounts of hypothetical particles and types of matter with "exotic" physical properties — like negative energy density — which either couldn't be found, or are simply beyond our technological capabilities.
Could we be closer to superluminal travel, anytime soon?by building a conceiving of a new type of hyper-fast "solitons" relying on sources with only net-positive energies — capable of traveling at any speed
What do you think?
