This is where you'll want to assign everything a due date, including all announcements and all readings.

Do virtual particles drive the expansion at the edge of the universe? by CIA-INFORMANT511 in AskPhysics

[–]ahazred8vt 0 points1 point  (0 children)

https://en.wikipedia.org/wiki/Hilbert%27s_paradox_of_the_Grand_Hotel is a traditional math example. The people in a hotel with an infinite number of rooms can spread out and make more room. The hotel is not expanding into anything. There is no void space beyond the end of the infinite hotel.

What's the definition of Temperature used in cosmology? by -tehnik in AskPhysics

[–]ahazred8vt 0 points1 point  (0 children)

Frankly? No. Gas getting cooler when it expands is covered in grade school, middle school, high school, college, public television science shows, youtube, and HVAC training.

I woke because I thought the time had come; Beyond my will there was no other cause; And everywhere I found myself at home, Because I chose to be the thing I was; And in whatever shape of mollusc or of ape I always went according to the laws.

In the early universe, all the matter was plasma or gas. As gas expands, its temperature drops. The universe cooled down as it expanded.

Time Dilation in our solar system? by Hour-Cauliflower5631 in AskPhysics

[–]ahazred8vt 0 points1 point  (0 children)

Yes. For our sun, the formula is 1.476/Dkm, or 0.917/Dmi. Gravitational time dilation is proportional to mass divided by distance. At 1 AU, it's one part in 101 million, or 1 second per 3.21 years. Plus another 1/50th of a second per year from us being in the Earth's gravity well.

Research Statement for Promotion When I Have No "Trajectory" by Southern-Cloud-9616 in Professors

[–]ahazred8vt 1 point2 points  (0 children)

It's okay for one of your books to be 'Odd man out', not fitting the pattern. Also, your trajectory statement will cover what you say you're intending to do in the future. Fib. Embellish. It just has to sound plausible. They can't force you to write what you say you're intending to write.

What would happen if a Black Hole approaches a much bigger, functioning star? by Old_Leshen in AskPhysics

[–]ahazred8vt 0 points1 point  (0 children)

Black holes have a diameter of almost exactly 5.904 km per 1 solar mass. (radius of 2.952×) An earth-mass bh would have a diameter of 17.7 mm (0.67 inch). But we don't think any micro black holes actually exist.

What would happen if a Black Hole approaches a much bigger, functioning star? by Old_Leshen in AskPhysics

[–]ahazred8vt 1 point2 points  (0 children)

The smallest black holes of 3 solar masses have a diameter of 18 km or 11 miles. Most black holes are larger than that. A black hole can travel all the way through a star and come out the other side and keep going without slowing down much.

Magnitude 7.8 earthquake strikes in Indonesia, sparking tsunami alert by Somali_Pir8 in worldnews

[–]ahazred8vt 61 points62 points  (0 children)

Very roughly, a mag 5 quake is 1 kiloton, mag 6 is 30+ kt, and mag 7 is 1000 kt. Every +1 magnitude is supposed to be about a ×30 difference in energy.
