Interstellar travel will use solar sail powered by terowatt lasers carrying uploaded humans.

Interstellar travel will use solar sail powered by terowatt lasers carrying uploaded humans. | what do I think with the technology and the physics that we have today is the most plausible way we go to the nearest star system. It's probably going to be something like a solar sail powered by terowatt lasers from Earth and we upload humans to the a small craft star whisps.
