According to my calculations the journey is 7900 miles and you begin it by dropping at 32 feet per second squared which means for each second dropped you speed up by 32 feet per second. However, gravitation will have a slowing effect as you near the centre of the earth.
I won’t show you all my working out, but the answer is 42 minutes 12 seconds and here is the irrefutable truth.
I like your fact, however unless you're planning on falling through a vacuum the biggest factor is air resistance. So I'm going to add a fact of my own. The terminal velicity for a falling human is 122mph. Therefore the fastest one could cover the 7900 miles purely by gravity is 65 hours, not allowing for acceleration from zero and deceleration due to decreasing gravitational pull.

Sorry, this is bollox. What happens when you get to the centre of the Earth's core. Does gravity suddenly reverse itself?
It's a bit like asking 'how far can you run into a forest?' The answer is halfway, because you then start running out of it.
Come on chaps think this one through please! /smiley/wink/thing/
Agree. You wouldn't come out the other side. Presumably you would 'fall' back and forth a little less each time like a pendulum slowing down, until you ended up floating right in the centre. Until someone dropped a rope down at which point you'd have to climb 4000 miles back out.

Would that not suggest gravity comes from a single source? I do not believe it does.
What if you started your fall from space and reached mega speeds?
If you made a large hole straight through the centre of the Earth then jumped into it you would emerge on the other side four minutes and twelve seconds later.
No you wouldn't, you'd burn to death in the earth's molten core.

Gravitation will slow you after you've pass the centre (assuming you haven't burnt to ashes by then, see my post above).
However, would your acceleration stay at 32ft/s^2 (10m/s^2)? The distance between your centre of mass and the earth's centre of mass will be decreasing, thus increasing the gravitational pull (https://en.wikipedia.org/wiki/Newton's_law_of_universal_gravitation). So, with force = mass x acceleration, if the force is increasing and your mass is constant, the acceleration should increase until you pass the centre, then you'd be decelerated by a decreasing gravitational pull as you pull away from the centre.
Tomatoes are the most commonly eaten fruit in the world.
And that reminds me. What's the difference between knowledge and wisdom? Knowledge is knowing tomato is a fruit; wisdom is knowing not to put them in your fruit salad.

What's at the other end of the hole if it goes straight through the centre of the earth (from the UK) ? Is it an ocean ?

Yeah, London roughly comes out in the ocean to the south east of New Zealand
Do you remember Pope John Paul I? The one who didn't last long and was immortalised in that well-known mnemonic "Thirty days have September, April, June and The Pope".
I have no idea as to the veracity of this. I could look it up but I can't be bothered. Anyway, at the time, it was said WBA were the only team ever to not win a game during the reign of a pope.
Going by Wikipedia, John Paul I began his papacy on 26 August 1978. On that day, West Brom beat Bolton 4-0 in the old Division One, and they didn't win again until 30 September (https://www.11v11.com/teams/west-bromwich-albion/tab/matches/season/1979/), two days after John Paul I died. So it depends when exactly on 26 August his papacy began, if you want to get very pedantic about it.
It wouldn't surprise me if there were another team who didn't manage to win in that period though.

Meanwhile, Huddersfield are the only club to go through the reigns of four Popes without losing a match.
Sylvester Stallone wrote and directed the film "Stayin Alive"
Fuck off did he!
Certainly did. Already had an Oscar for Rocky as well.
And Michael Douglas got an Oscar for producing One Flew Over The Cuckoos Nest in 1975.
Stallone's trajectory is really interesting! He wrote all the Rocky movies except for Creed, loads of his big hits (Cliffhanger, Over The Top, Cobra among others), directed Rockys 2,3,4 and 6, the fourth Rambo and the first Expendables.
His time in the movie wilderness at the turn of the century was largely down to his desperation for the public to take him more seriously, he hated being associated with the dumbass Balboa and the monosyllabic Rambo so he made shitty movies that made him look good (Driven, Daylight, even Tango and Cash saw him wear a pair of glasses and look studious).
He eventually realised how lucky he was to own those two characters, so he embraced them (hence Rocky 6 and Rambo 4), which bought him a ticket back into the big time with a three-movie deal that led to the likes of the The Expendables.
But it's no coincidence that Creed is probably the best Rocky script since the first one - Sly knows how to write an action movie, and he knows how to make Rocky and Adrian shout at each other. But that's about it!

The Aztecs used all sorts of advanced agricultural techniques. These included terracing and even "floating fields" made of matted reeds with soil from the lakes. With the lakes themselves solving the irrigation problem. They were also aware of the advantages of leaving a bed fallow to allow the soil to recover.
The Aztecs planted three crops, called the Three Sisters, close together. Often on raised beds with rotten fish and ash for nutrients mixed with the soil. The three sisters are maize, beans and squash.
The maize takes nitrogen from the soil, which the beans then replace. Bean plants need firm support on which to grow; maize stalks provide that support. The large squash leaves shade the soil, which keeps moisture in and keeps weeds out.
It is thought another plant the Mexican marigold (aka Tagetes) were also mingled in. These have the extraordinary ability to actually kill off perennial weeds and repel nematodes and other pest insects.
Some Native American tribes added a fourth sister, a sunflower or bee plant. These attracted the pollinators to the crops.

Like Cleopatra being closer to us than her to when The Great Pyramid was built

(And don't say 'Roberto Dyas')
Need to be sown early in the year though. Half hardy annuals. https://sarahraven.com/flowers/seeds/annuals/tagetes_minuta.htm
