Do you think there was anything before the big bang?

There is no nice way to say this, but you Humans are doomed, IMO.

I have been Logically and Mathematically studying the Future of your Solar System, and FRANKLY, it is looking bleak!

Tremendous problems ahead:

Your Star is going to blow up in the long run. Planets will scatter.

I have found sufficient chinks in Schrodinger's Quantum Equation to offer some Hope, but frankly, it's hopeless in reconciling with General Relativity:

Too Little, too Late, IMO:

A broken theory if ever I saw one. Sorry. Unitary Matrices are scarcely improved by Isometric ones. Obvious flaws.

But keep at it:

Never give up! 🙂

In short, if the dimensions of Hilbert space increase in number as the universe expands, then quantum mechanics would be reconciled with general relativity.

(A Hilbert space is an extension of the ordinary three-dimensional space in Euclidean geometry.)

If a man with your combination of academic disciplines says this reconciliation is hopeless, then who am I to disagree! 😀
 
I didn't really understand the isometric idea at all, or how it helps. Maybe I was too quick to dismiss the idea of adding extra dimensions to the Hilbert Space, but it seems like just another desperate fix.

More accessable was Melvin Bragg discussing the Electron with some top scientists, on Thursday on BBC Radio 4:

Quite interesting and unusual for Radio 4 to discuss science. Not too heavy either. You have to log in to Sounds to listen, but no TV License needed, Just an email and a password for your account.

I would hope it works worldwide.

Will do, Steve.

In fact, I've just left BBC Sounds after listening to Ken Bruce's Tracks of My Years special celebrating the UK release of the Beatles' Love Me Do 60 years ago on 5 October 1962. Choosing their Fabs favourites are celebrities such as Priscilla Presley, Agneta Fältskog and Sir Elton John.

Now Steve, I'll promise to say nothing negative about the electron provided you say nothing negative about The Beatles! :up:

I couldn't find the Ken Bruce Beatles tribute. I was of course listening to Tony Blackburn's Golden Hour as usual... Sanity returns to Radio 2 after all the hideous modern dance music on Friday and Saturday nights. LOL

Thought I would have a go at Paul Dirac's Electron equation, which I first encountered in the Devonshire Arms Pub in Kensington.:

My Physics friend, Simon, explained the anti-electron on the back of a beermat. He used a 4 matrix of Space and Time, IIRC.

We should all recognise this one, especially when bimbling around Westminster Abbey on the tourist trail.

No, I don't know what it's about either, but I see mass and a wave function there, and the fish thing is the reduced Planck's constant times i.

The trick was to incorporate Special Relativity into Quantum Mechanics apparently. 😎

At least we know that antielectrons, or positrons, actually exist. If not, PET (Positron Emission Tomagraphy) would not be possible.

A positron-emitting radioisotope can be incorporated into a compound such as glucose so that its biological movement in the human body can be tracked.

In a PET scan, the positrons are not detected directly, but when they slow down and annihilate electrons the resulting gamma ray photons produce flashes of light in a special camera.
