Скачать или смотреть Why It’s IMPOSSIBLE to Leave the Solar System | Brian Greene

Why is it nearly impossible for humanity to leave the Solar System? In this mind-expanding speech, renowned theoretical physicist Brian Greene (Biran Greene) explains the extreme physical, technological, and cosmic limits that trap us within our stellar neighborhood. From unimaginable interstellar distances to energy constraints, time dilation, and the speed of light barrier, this talk reveals why escaping the Solar System may remain forever beyond human reach.

Blending modern physics, cosmology, and real scientific constraints, Brian Greene breaks down why even advanced civilizations would struggle to travel beyond the Sun’s gravitational domain. This speech challenges science fiction dreams and replaces them with hard scientific reality.

If you’re fascinated by space travel, astrophysics, the future of humanity, or the true scale of the universe, this talk will completely reshape how you think about our place in the cosmos.
