Which is also a crazy thought. I would have thought the force would have been more than enough to "make the golf ball dead" at that distance. Either way, the poor golf ball would be in for a very bad time. The surface of the neutron star, as I understand it, is all but indestructible as far as...

Hmm. Let's see. I believe we can use the following equation for this calculation. ##F = \frac{GmM}{(r+h)^2}## If we assume that the golf ball is a standard one, then it's height is equal to its diameter (d), so 0.04267 meters. If the bottom of the ball is at 1 meter above the surface (h) then...

Off hand, I remember this one from several years ago. I had to go back and look it up. Yes, I am aware YouTube isn't necessarily always a source of reliable information. I also recall hearing a similar claim from documentaries in the past, one I specifically remember was this one (the clip is...

Hi all. I'm trying to get my head back onto mathematical thinking and I'm setting myself projects to undertake to facilitate that. It's been too long since I've worked with numbers like this. My first task was to work out how much energy would be released when dropping things onto a neutron...

Ahhh. That does make sense, thank you for clarifying that segment.

Hi! Please don't spare me any juicy details. I can take it! I'm specifically interested in type II supernovae and their stellar precursors in my following questions. Stars above the mass of 8 times the size of the sun go through successive burning phases in their cores, resulting in a cores of...

Thank you! I'll add that one to the list too.

Thank you, I'll add it to the list. Like I said, I'm a bit rusty and I need to get pack into practice. I know it's a very... complex and difficult topic, but that'll be good motivation for me to get back into practice. Computer science is far simpler. Far, far simpler.

I actually started studying astrophysics before I dropped off the academic ladder after suffering a breakdown. I was about 2 years in, so not an expert (by any stretch) but I'm not completely oblivious either. I ended up restarting my education from a different direction, but I'm still...

Hi all! It has been quite a while since I last posted here. Again. I'm currently interested in supernovae and the exotic stellar remnants that are left behind from such events. I'm interested in the physics and science surrounding this subject, it's something that I currently have an interest...

Hey guys! Basically I have a table of prime numbers. What is to write this table as an image - from 1 too 480000 - showing each cell that is a prime as white and the others as black. So basically I'm cycling the numbers from 1-480000 and if they are prime then I want the cell white and...

Has anyone else been following the Firefox Guinness World Record Attempt? I'm going to put my name down just for the sake of it - plus if it goes through there would be an entry in the world record book that I actually contributed too :D Anyone else interested / heard about it?

Its pretty damn impressive... and they are not shure how it was one, its one of those science "OOps we did something new!" moments :D Cheers, Ryan Jones
