- Oumuamua, a quarter-mile long asteroid tumbling through space, is Hawaiian for "scout", or "the first of many".
- It was given this name because it came from another solar system.
- Some claimed 'Oumuamua was an alien technology, but there's no actual evidence for that.
- The Parker Solar Probe is set to uncover a mystery about the sun: Why is it's corona hotter than its surface?
- NASA's ability to fly a probe so close to the sun is a marvel of engineering.
- Michelle Thaller, an astronomer at NASA, explains why the Parker Solar Probe is so hot right now.
- Time can change depending on how fast you're moving through space. Also, time can "flow" at different rates for different observers.
- Light doesn't experience time — it exists outside of time.
- We perceive space and time differently, but they may be woven together. For instance, they both balance each other out: If you are still, time goes by at a natural rate. However, if you move through space very fast, time begins to slow down.
NASA astronomer Michelle Thaller is coming back to Big Think to answer YOUR questions! Here's all you need to know to submit your science-related inquiries.
Big Think's amazing audience has responded so well to our videos from NASA astronomer and Assistant Director for Science Communication Michelle Thaller that we couldn't wait to bring her back for more!
And this time, she's ready to tackle any questions you're willing to throw at her, like, "How big is the Universe?", "Am I really made of stars?" or, "How long until Elon Musk starts a colony on Mars?"
All you have to do is submit your questions to the form below, and we'll use them for an upcoming Q+A session with Michelle. You know what to do, Big Thinkers!
Getting to close to a black hole is a nightmare waiting to happen.
- Like ocean tides caused by gravity, a nearby black hole would create a 'tide' inside your body, which is mostly water.
- As your body drew nearer to the black hole, your head would be stretched away from your feet.
- Scientists call this streching "spaghettification", from the word of spaghetti.
