We will travel again, but it will not be the same.
COVID-19 has upended global travel and brought the world to a standstill.
Do space and time really exist? NASA astronomer Michelle Thaller looks at the implications of Einstein's famous equation E=mc2.
- NASA astronomer and science communicator Michelle Thaller explains that the real brilliance of Albert Einstein is that he was able to bridge ideas that appeared to others to be in different realms.
- The thing Einstein is most famous for is the equation E=mc2. Thaller explains why that equation is so mind-blowing: Pure energy and matter are the same thing. That means, as humans, we are both made of matter and of pure energy, and as pure energy, we would not experience space or time.
- "I think that, once we really understand this, we're going to be in for some very difficult truths to accept," says Thaller. "It may be that there is no space or time as we know it, really."
Why did the dinosaurs go extinct? Because they didn't have a space program.
- Space exploration is more than just the ultimate adventure, our study and investigation of space yields great scientific rewards, says astronaut Garrett Reisman.
- Earth is wonderful, but it won't last forever, so it's important that we maintain a big picture view to ensure the survival of the human species.
- Exploring space is our ticket to "the ultimate plan B," according to Reisman. If there were to occur a mass extinction event on Earth, the humans that inhabit another planet in our solar system will be the only hope of human survival.
The space agency is ready to establish a base camp by 2024.
- NASA's Artemis program plans on establishing a base camp on the Moon as soon as 2024.
- After testing technologies and securing resources on the surface of the Moon, NASA plans on exploring Mars.
- A number of robotic missions will first establish the Gateway, the flight path between Earth and the Moon's south pole.
The racing plane is hoped to be the fastest electric plane in existence.
- The electric aircraft industry is just starting to get off the ground, with Siemens breaking the world record for the fastest electric aircraft in 2017.
- With ACCEL (Accelerating the Electrification of Flight), Rolls-Royce intends to beat that record in the spring of 2020.
- While these are existing developments, the field of electric aviation has significant challenges to face before we can expect to see electric long-distance passenger planes.
