Weird Time, A Planet in a Slingshot, and a New Eye on the Cosmos!
|The Cosmic Companion||Aug 31, 2019|| 1|
A thought experiment caught the attention of physicists this week, causing researchers to reconsider what they thought they knew about time at the quantum level. An exoplanet was found in a slingshot orbit around an alien star, and assembly is now complete on the most advanced space telescope ever designed.
Let’s take off!
The Week in Space
It’s Time, But Not as we Know It - A new type of “quantum time order” may exhibit itself at the minuscule scale of sub-atomic particles, a new thought experiment suggests.

Researchers from the University of Queensland suggest that relativistic effects by gravity on the passage of time will still be present even if an object is in a state of superposition, both existing and not existing at the same time, like Schrodinger’s cat. Such conditions would result in bizarre behavior, as events that should happen one after the other will unfold simultaneously.

Massive World Slingshots Around Star - An exoplanet at least three times more massive than Jupiter has been spotted slingshotting its way around its parent star, new observations reveal.

The planet, HR 5183 b, comes as close to its star as the asteroid belt between Mars and Jupiter orbit from our Sun. The highly-elliptical path of this massive world, however, carries it as far away from it’s parent star as the distance between Neptune and the Sun.
The Cosmic Companion talks with Sarah Blunt, one of the researchers that discovered this unusual world.

James Webb Space Telescope Now Assembled — What’s Next? - The most advanced space telescope in history is now complete. Viewing the Universe in infrared light, this observatory could revolutionize what we know about astronomy and our place in the Universe.

What will the James Webb Space Telescope accomplish, and what science will this new facility undertake? The Cosmic Companion looks “under the hood” of this magnificent spacecraft.
