Hawking's journey through time

"His most recent major paper, written with Thomas Hertog in Paris and Jim Hartle in California, came up with a deeper understanding of cosmic inflation, the astonishing growth spurt of the early universe. Their work suggests that the universe did not have just one unique beginning and history, but a multitude of different ones - and, moreover, that it has experienced them all. This "top-down" cosmology suggests that the present "selects" only those past histories that lead to the present."

I have no idea what that means, but it does sound interesting.

We consider landscape models that admit several regions where the conditions for eternal inflation hold. It is shown that one can use the no-boundary wave function to calculate small departures from homogeneity within our past light cone despite the possibility of much larger fluctuations on super horizon scales. The dominant contribution comes from the history exiting eternal inflation at the lowest value of the potential. In a class of landscape models this predicts a tensor to scalar ratio of about 10%. In this way the no-boundary wave function defines a measure for the prediction of local cosmological observations.

Wow.

I've read A Brief History of Time, and I definitely didn't understand all of it, but he did an excellent job with making a good deal of it accessible. I won't ever understand why a lot of his findings are the way they are, but I appreciate that he makes the results and implications available to us non-physicists.

I've got a few of his books on Audible (unabridged) quite enjoy them
The Universe in a Nutshell
A Short History Of Nearly Everything (Bill Bryson)
The Fabric of the Cosmos (Brian Greene)
A Briefer History of Time

Man and the cosmos are two different bodies. Understanding and interacting with the mysteries of one body (Man) is sufficient.

I think I will have to wait for the 'Briefer' version to come out.

the International Space Station cost more than $100 billion.

in the pursuit of vain glory scientists have stepped over the bodies of starving illiterate children in Africa to get more than $100 billion in funding to build this pointless tin can in space.
Just imagine how much good can be done in Africa with this amount of funding?

Just imagine how much good could be done in Africa if you spent every penny you had except that which paid for your organs to remain in tact.

You can blame any seemingly frivolous spending of money as taking another dollar out of an African child's pocket.

And just throwing money at Africa won't solve the majority of their problems by the way.

That is what is done now, so far it doesn't work since corrupt regimes get in the way.

that is right you can blame any frivolous spending of money as taking another dollar out of an African child's pocket.

yes and up until now money hasn't solve the majority of Africa's problems. Because scientists are to busy spending their time and 100's of billion of dollars to send pointless tin can's in to space,
and that is why scientists are to busy to help solve the majority of Africa's problems.

Which are you solving?

 

[gattaca]

Which are you solving?

go on than. send me a check for $100 billion.
and you will see for yourself what i can do for the children of Africa.
first i would teach every child in Africa to read and write.
i would give them all food and water. and put a roof over their heads.

What has building the space station got to do with only scientists? Politicians allow them to happen and voters are happy sometimes for them to spend loads of money on this projects.

Science is not where most of the money goes. It's a spec of dust compared to the vast amounts spent by governments on so many other things. Consider the fact that the recent wars in the Middle East cost somewhere on the order of $1-4 trillion dollars.

Science is important, and it is something worth funding on principle. If there was no science, there would be no technology for the wells being installed in poor African cities.

We all hate the circumstance Africa is in and we all want to see it change. But it's pretty absurd of you to postulate that the International Space Station and Stephen Hawking are the ones in the way of riches and health for the average African.

Think of the 3 billion dollars that goes from the USA to Israel to help fund its army, that could be better spent in Africa.
