Thank you SOO much.. I really appreciate your help.. :)

Ok thank you for your help. :)

It isn't homework... I am trying to learn this kind of thing but have no access to any textbooks that could help me... are there any other textbooks that explain and could teach me this?

I'm just starting this, but what would the complex conjugate of Ψ(x,t) in the equation : |Ψ(x,t)|^2= Ψ(x,t)* Ψ(x,t) be.. Let's just say, for example, that x is 4 and t is 9... Please help if you can.. Could you please help me out with the steps to completing this, because I really want to...

OK thank you for the help and advice :)

I've been working on it, and I think this may work, M = z(rc^2)/G , where "z" is the redshift, do you think this would work, it seems to be giving around the correct result, but I would much prefer someone wiser to review and correct...

Let's say it is gravitational redshift.. If you can, could you please also explain for the other two types of redshift?

Hi everyone, Is there a simple formula/equation for calculating the mass of a star simply by measuring it's redshift. I know there is a way to do it, but have been unable to find any clues on the web.. Thanks for your help! :)

This may seem irrelevant, but if we somehow found a way in which to accelerate an object with mass to the speed of light, would it have infinite gravity? Because we all know that mass increases with speed and that mass becomes infinitely large when traveling at the speed of light...

The only such experiment I have heard of that seem to make events appear in a different order would involve different frames of references and observers in separate locations.. But apart from that I'm not completely sure...

Haha good point! :)

Hello, I'm Lachlan Pearce and love physics (mostly special relativity, astrophysics, and a little of quantum physics). If anyone wants to discuss any of this I'd be happy to.. :)

Use an app called "Shazam", it listens to songs and then identifies them :)

I found some quick information here http://www.universetoday.com/70111/astronomy-without-a-telescope-strange-stars/ , another tiny amount here http://en.wikipedia.org/wiki/Quark_star and a few others that didn't really give me much information. These are my sources but yet neither of them goes...

I was discussion stars with a friend of mine when he mentioned strange stars. I had no idea what is was so when I got home later that day I researched it. At that time I thought he simply meant stars that were 'strange', but once I had researched I found that they were a certain type of dense...
