What the HECK is Time?! (in Einstein’s Relativity)
The Science Asylum – Apr 28, 2020 – 11:49
In special and general relativity, we imagine time as just another dimension of space in something called “spacetime.” Unfortunately, this picture leads to questions about determinism and free will. Is that really how it works? What does the concept of spacetime actually say about the universe and about time?


What’s Under The Ice In Antarctica?

Animation of Black Hole Disk Flare in Galaxy OJ 287
NASA Jet Propulsion Laboratory – Apr 28, 2020 – 1:21

Two massive black holes are locked in a dance at the center of the OJ 287 galaxy. The larger black hole is surrounded by disk of gas; it is also orbited by a smaller black hole that collides with the disk, producing a flare brighter than 1 trillion stars. But because the system’s complex physics affects the smaller black hole’s orbit, the flares occur irregularly. Scientists used NASA’s Spitzer Space Telescope to detect one of these bright flashes on July 31, 2019, confirming that they can now anticipate the timing of these flares to within four hours using a detailed model of the system.

In the second half of the video, the animated diagram on the left illustrates the orbit of the smaller black hole (the red dot) around the larger black hole (the stationary white dot) and its collisions with the disk of gas (the pink line), which occur twice per orbit. The years of the collisions are indicated below the diagram and in the graphic on the right shows, dating to 1886.
After more than 16 years of operations in space, Spitzer was retired on Jan. 30, 2020.


A day in the life of an astrophysicist in LOCKDOWN
Dr. Becky – Apr 29, 2020 – 17:10
****Stay home. Save lives**** Like many people in the world right now I am in lockdown in the UK, working from home. But as an astrophysicist, well… the Universe doesn’t stop and neither does science. However, astronomy and astrophysics have been affected somewhat by the pandemic, so hopefully, this video will shed some light on that for you all!


Why Do Fetuses Kick So Much?

The feeling of a kicking fetus is perhaps one of the more fun parts of having a baby, but these movements serve a purpose well beyond letting you know that that little thing is in there! Hosted by: Hank Green


How Science Is Trying to Understand Consciousness
SciShow – Apr 29, 2020 – 12:33
Figuring out exactly what consciousness is and whether or not it could emerge in non-human things has stumped us for centuries. Now, analyzing it from a scientific perspective might not just be possible, but necessary. Hosted by: Hank Green


How the Andes Mountains Might Have Killed a Bunch of Whales
PBS Eons – Apr 29, 2020 – 8:55
At a site known as Cerro Ballena or Whale Hill, there are more than 40 skeletons of marine mammals — a graveyard of ocean life dating back 6.5 million to 9 million years ago, in the Late Miocene Epoch. But the identity of the killer that they finally settled on might surprise you.


How Climate Change Is Creating More Space Junk

You’ve probably heard a lot about how climate change is affecting our planet, but did you know a warming climate also affects objects in space?
