Is ACTION The Most Fundamental Property in Physics?

Learn More About NordVPN at: https://nordvpn.com/spacetime

It’s about time we discussed an obscure concept in physics that may be more fundamental than energy and entropy and perhaps time itself. That’s right – the time has come for Action.

Vice President Kamala Harris Visits NASA to See Climate Change Work

Vice President Kamala Harris Visits NASA to See Climate Change Work

The urgency of Earth science and climate studies took the spotlight Friday, Nov. 5, as U.S. Vice President Kamala Harris visited NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Alongside NASA Administrator Bill Nelson, the vice president received a firsthand look at how NASA studies climate change and provides crucial information to understand our planet’s changes and their impacts on our lives.

The vice president met with scientists and engineers to discuss:
• The first images captured by the Landsat 9 satellite, a joint mission of NASA and the U.S. Geological Survey (USGS) that launched in late September to monitor the Earth’s land surface.
• A new Earth science mission entitled Investigation of Convective Updrafts (INCUS) that will study the behavior of tropical storms and thunderstorms, including their impacts on weather and climate models.
• The Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission, which involves an instrument currently under construction at Goddard for a 2022 launch. PACE will extend and improve NASA’s record of satellite observations of global ocean biology, aerosols (tiny particles suspended in the atmosphere), and clouds.
• The GOES-R program, whose GOES-T satellite is scheduled to launch for NOAA in February 2022 to improve weather forecasts.

[LIVE 3 MILES AWAY!!!] Watch SpaceX launch 4 civilians into orbit for Inspiration 4!!!

SpaceX will launch four private astronauts on the first free flight mission of Crew Dragon on Inspiration4. The Falcon 9 B1062-3 will launch Crew Dragon C207-2 into a 575 km low-Earth orbit; this will mark the highest orbit a crewed mission has gone to since the STS-103 mission in 1999. The Inspiration4 mission will launch from Launch Complex 39A (LC-39A), at the Kennedy Space Center, in Florida, USA.

New Results in Quantum Tunneling vs. The Speed of Light

Learn More about Brilliant: https://brilliant.org/SpaceTime/

Paradoxically, the most promising prospects for moving matter around faster than light may be to put a metaphorical brick wall in its way. New efforts in quantum tunneling – both theory and experiment – show that superluminal motion may be possible, while still managing to avoid the paradox of superluminal signaling.Paradoxically, the most promising prospects for moving matter around faster than light may be to put a metaphorical brick wall in its way.

Live Q&A with NASA Planetary Defender

Live Q&A with NASA Planetary Defender

NASA planetary defender Dr. Kelly Fast has a hard and fast rule: “Find asteroids before they find us.” Working in NASA’s Planetary Defense Coordination Office, Kelly is helping send the #DARTMission to test “nudging” an asteroid in space. DART, short for Double Asteroid Redirection Test, is a planetary defense-driven test of technologies for preventing an impact of Earth by a hazardous near-Earth object. DART will be the first demonstration of the kinetic impactor technique to change the motion of an asteroid in space. NOTE: the target asteroid is currently not a threat to Earth.

Tour Firefly Aerospace’s Factory and Test Site With Their CEO, Tom Markusic

Join me as I walk through Firefly Aerospace’s Texas test site and factory with their CEO, Tom Markusic. This was a highly detailed tour where we got to learn a ton about their engines, their rockets, and rocket science in general. It was super fun chatting with Tom because he has a Ph.D. in Mechanical and Aerospace Engineering, so I learned a lot!

Inspiration4 | Splashdown

Inspiration4 | Splashdown

After three days orbiting Earth, Dragon and the Inspiration4 crew– the world’s first civilian mission to orbit – safely splashed down off the coast of Florida at 7:06 p.m. EDT on Saturday, September 18, 2021, completing their first multi-day low Earth orbit mission.

Dragon performed a series of departure phasing burns to leave the circular orbit of 575 kilometers and then jettisoned its trunk ahead of it deorbit burn. After re-entering the Earth’s atmosphere, the spacecraft deployed its two drogue and four main parachutes in preparation for the soft water landing.

Upon splashdown, the Inspiration4 astronauts were welcomed home by the SpaceX team and quickly brought on board the recovery vessel. SpaceX transported Dragon back to Cape Canaveral for inspections and refurbishment ahead of future human spaceflight missions.

Will Constructor Theory REWRITE Physics?

Check Out American Voices: Keep it Close: https://youtu.be/LMJqb5A51_Y

The people behind the greatest leaps in physics – Einstein, Newton, Heisenberg, all had the uncanny ability to see the fundamentals – see the deepest, underlying facts about the world, and from simple statements about reality they built up their incredible theories. Well what if we all had a recipe book for doing exactly this. Well, one might be just around the corner and it’s called Constructor Theory.
