Singularities debunked?
« on: 13/09/2013 01:15:34 »
I have found this article.

http://finitenature.com/no_singularity/

This discusses the problems singularities bring to general relativity and examines an alternative. The author is less than kind to Hawking et al but this should not invalidate the general thesis. Any other views on this?

As an addition the problem I do see with this approach is the fact that it assumes all the collapsed mass is at the surface of the event horizon.

I have just had an interesting thought. What if gravity is not a particle as such but the absence of a particle? When electromagnetic radiation is emitted it leaves a particle short. The photon has borrowed energy and momentum from the particle which it then wants to get back. Thus it attracts the nearest particle to itself in order to counter-balance the shortfall. Would there be an equation to test this proposition?

In this way buoyancy could be explained as particles with more mass and lower energy states may be more susceptible to 'gravity' having more to donate. This could provide a good model of solidification of liquids and gasses.

There is nothing in that website that tells you who the author is and it appears that he doesn't know what he's talking about. No physicist I know would make a mistake as saying Relativistic physics appears to divide by zero - when modelling gravitational collapse! as this guy does on that page. There is no such "divide by zero" problem in GR. And there really is no singularity problem that I know of. All that can be said is that there are discontonuity in the field equations of GR in certain instances. But that was true in Newtonian dynamics and is also true in relativistic electrodynamics. A point charge has an infinite charge density and mass density. I don't see that as being a serious problem. Just a curiosity telling us that there is more to learn. The rest of your comments don't make any sense to me.

The author is Tim Tyler.  His other domains here... http://timtyler.org/

What about that tells me what his education is or why I should take anything he saus seriously? Where's his educational and work background? In the absense of that where are the derivations proving his claims?

Don't shoot the messenger.
After seeing his 'domains' I lost interest in 'digging' further.

Yes he is a transhumanist which I did not realize. Not something I agree with so apologies for posting the link.

No worries my friend. I know you much better than that and know that you don't fall for things like that once you dig into it. My compliments for you and jefferyH for seeing right through him. :)

jefferyH - I never heard of the term transhumanist before. I read a bit about them at http://en.wikipedia.org/wiki/Transhumanism

Weird!!

It's 'out there' to say the least. To them every problem we have is going to be solved within decades
