Sorry, it's a bit late but a great Horizon on Beeb 4 just now - about the origins of the universe.
Now, the show production is annoying. Not that I have a suggestion how else to do it. So, who gets the idea that...
The universe expands and entropies to the point where all mass has decayed to mass-less photons. At which point there is no sense of time, space or gravity. So the size of the universe is at once huge and infinitesimally small. Then there is a big bang!

Load of cobblers. 🙄
I just want to know why they get so much funding.

That's a bit much, Al! 😯

I think they do the funny maths in between giving lectures.
Time on big telescopes costs ££££ though. The laser interferometry facility looks expensive esp. as it's compromised by noise. But the space version (LISA) is eye watering - 2 billion Euros. Imagine trying to formation fly a constellation of robotic spaceships millions of km apart at Lagrange points with enough precision not to mess up the interferometry! It will likely get axed. Which is a shame in a way as the LISA Pathfinder mission development is ticking along OK.
Be cool if they detected gravity waves - I think Einstein's work predicts them, and he was a dude.
Typical Horizon dreamy music, voice and visuals aside, was very interesting. Had to rewind as I thought I'd missed the bit where they tried to explain what Mersini Houghton's theory was. They sort of said it was a bit of everything, applying string throry to a wave representation of the universe, but that was it. Assume it was so abstract and complicated that they just gave up!
