I took a ride on a moving radio telescope 

awesome

ok

until full visual episodes come to BRvid im not listening

I really enjoy Lateral. Keep up the great work.

Nice.

Unless the building is mostly thick concrete and the bricks are just décor essentially

@@AFGuidesHD if I understood correctly, its not resting on the building, but the separate central column which seems to be made out of a pipe-shaped steel outer layer and a massive steel core column.

@@AFGuidesHD Like the guide said in the video, the dish and the central column supporting it have their own foundation and are not connected to the building, the building is entirely aesthetics to house personal and equipment.

The dish is on a separate foundation from the rest of the building, they mentioned that in the video.

5:23

probably had a quite a bit of school trips over the years...

As someone who visited this telescope last year and had this legend as our guide I can agree

Yep, totally agree.

Yup, the fact that he's using comparisons to give his audience a sense of how large things are tells me he's been doing this for a long while

He needs his own... radio show.

That's so cool! What was the internship for?

How does this have 229 likes but only one reply?

When he hopped onto the ground I legit let out a “that was freaking awesome.” I had no clue it would go that far.

There's something about spending time among people with planet-sized brains which simultaneously makes you feel smarter but also makes you feel very basic. :)

Just wanted to say that, it seems he has been waiting his whole life to do this presentation.

He really knows, how to show this telescope!

i especially love how he had a feather ready ( 2:30 ) for occasions like this, you really can tell he loves his job

I got that impression immediately. Didn’t seem even slightly bothered at all!

John needs to make sure to file his TPS Report on time.

When Tom said "a film that was shot here more than 20 years ago" I went out in search of a movie made in the 80s, saw the film made in 2000 and thought "huh, they must have remade it then" before my temporal awareness kicked back in. *double facepalm*

The dismissive way Tom says "a film shot here 20 years go" as if that film wasn't fantastic is kind of disappointing

The Dish is actually one of my favorite films

@@milamber319 Let's say instead that he employed the fantastic psychological trick of mentioning important information in a way that seems trivial - listeners pick up on that cue without realising, immediately stop what they're doing, and find the film. Okay, I totally made that up, but that's what I did, so something must have worked! 😎

@@isaacthehungry7210 The Dish is my favourite film! I watch it a few times a year. I was a bit miffed when Tom describes the Working Dog team as "a bunch of Americans" who called riding the dish a "hayride" in the movie.

built in the 1950s too

Tell me that you didn't watch the whole video without telling me

The scale? No. This video is about a telescope, not a scale. 😉

Scale of technology? Look at the great pyramids they're not just burial tombs. Look into it.

I don't think you can buy that one!

I presume you've seen his video from the town of Asbestos?

That’s WILD

Like staring at the shadow on the wall and being able to tell that someone lit a match, miles away.

I still have the video paused contemplating this fact. I had to replay it a few times to make sure I wasn't misunderstanding him. That's a *crazy* piece of information. EDIT: Followed up by the cell phone on the moon's surface bit. I had no idea we were talking those scales.

Genuinely mind blowing, it shows just how much information we're missing! We've learnt so much from such a small amount of data!

and the aliens are still able to hide themselves from the mess we call humanity

Haha I did the same thing was a great experience

It will not be rebuilt. The owner said so.

Also remember that the signal coming from Voyager is so weak that they can barely receive it with those massive dishes, and the communications back are done using multiple hundreds of kilowatts of power, sent via the same dish, and the spacecraft will only get them more than 24 hours later, and reply also 24 hours later on. Also the voyager spacecraft were never actually designed to last that long, they were actually spare Mariner spacecraft bodies that got a massive antenna grafted on to allow communications, then a RTG instead of solar panels, and thus were sent out. Now down to a little over 200W of power for use on the spacecraft, so by around 2030 they will no longer have enough power left to transmit high speed data, and soon after that will lose all transmit power, though the computer will continue to operate, and keep the spacecraft aimed at the sun for decades afterwards, but will be mute.

@@SeanBZA like in death Hearing goes last

@@SeanBZA ..Voyager's dish and power were deliberately designed to be a small as possible, so the signal was only just strong enough to be detected - it has a fiendish error correction protocol to try and compensate which is why the images take so long to download - it is an extremely weak signal to start with (just not by today's standards)

@@davidioanhedges Yes it is small, but by the standards for the Mariner probes it was based off it was huge, and the error correction was designed to be as robust as possible, but also as simple to implement in the spacecraft as well, as complexity at the time came with added mass, and you had an overall maximum launch mass you could not exceed. Thus the panels were made from Beryllium aluminium alloy, milled as thin as possible in low stress areas, and milled away completely where not needed, just to avoid the mass of a rivet to hold a gusset in place. Remember at this time digital decoding was done using discrete chips, or using massive computers, so to put the error correction and forward error correction in the probe they had to choose between robustness, data rate and mass, choose one, because mass is the severe limit. Even the digital data recorder was special, because it had to survive in a vacuum, and it still does work now, that design and the tapes are still holding up.

Not "from the stars". We get quite a bit more energy than that from a single star in a second. Just _for the purposes of radio astronomy._

One of these days you should just go down there, ask questions, and see if you can do some of these types of things! People that do this kind of work are very passionate and sharing that passion with others is one of the joys of life!

I agree. You would be surprised at what you may be able to do if you simply ask.

And don't forget to turn off your mobile phone

As David Berrimans relative, i once broke a dish after dinner into hundreds of pieces that i had to pick up and he told me he wasnt jealous while up close and personal....

@@diegopescia9602 don't matter on maint day I would expect

You might say that he was *stellar*

We all know the only reason why Tom was in Parkes was for the Elvis Festival hahaha

John be like : "If it ain't broken, we ain't fixin' it!"

He probably appreciated having a genuinely receptive audience, too, rather than a bunch of hyped up school kids.

I believe they have a submissions email address, you should send it in.

Thank you!

@@willhawkes8875 Do you get to see them in action? I would love to see that shown in a future Tom Scott video!

No doubt! I never thought about having the edge of the scope go down to get the equipment into the dish. But then, I should have thought of it. I’ve used the power of a piece of heavy equipment to help assemble and disassemble itself!

@@dangeary2134 Mobile crane? I think self-assembling cranes are such a cool design principle

like treebeard picking up a hobbit

Makes perfect sense, too! You already have an extremely robust and heavyweight piece of machinery to lift things high up, why not use it?

typical Aussie thinking :) We invent a lot of stuff cause of this sort of style of thinking. Why work hard if there's an easier way to acheive the same result :)

most modern cameras have levels, that's why the operator managed to keep the horizon

The camera operator was holding a GoPro 360° camera with which you can do all that in post-processing. Not to discredit them, it's just the solution that makes the most sense for that situation.

Plus Jack is literally holding a camera on a gimbal 🤷‍♂️

Flinging whilst as you do.

This guy is still living in the 60's xD

Is ATCA the multi dish on rails one near Narrabri? I've always wanted to go take a look at that. Also really excited to see what the Murchison square kilometer array finds.

@@muddydave01 Yes it is. I did my high school work experience week there many decades ago. If you do visit, remember the visitors centre is now unstaffed, so you can't just turn up and get any sort of tour or ask questions. If you're making a long trip specifically to see the site, I would suggest calling them or emailing them to see if there's any chance of a tour or anything. There's a lot of technical information that is fascinating but not really explained in the visitors centre.

Hey, how can we trust you to do good science when you didn't see the Vogons coming!

He may be, we on the other hand are not at all tired of radio telescopes. Didn't you love the look on Tom's face when the guide did the feather drop analogy? Not often do we see Tom Speechless!

I get giddy making a LED flash or a gate open from a distance with electronics I've made. Making a thousand tonnes dance must be next level

Also good sense of humour too

✝️ LORD JESUS DIED & ROSE AGAIN TO PAY THE DEBT OF UR SIN! ✅By Faith in the sacrifice God has made are we saved from the penalty of sin! 🔵Turn from your sin that leads to death & accept His Gift that leads to eternal Life! 💜We are all sinners that need God. No one can say they are perfect to be able to pay their debt of sin. This is why only God could pay the penalty for us, that is merciful Love!

Yes, this guy, while rather matter of fact, was also BRILLIANT with his explanations.

Totally, such a well crafted way of telling stories.

Imagine theres an alien radio wave that hit directly at Tom at the time

It was such a simple yet superbly powerful demonstration.

no wonder a smartphone, which emits radiation in the order of milliwatts, shines as bright as a bonfire to a telescope like this, even when placed on the moon.

I'm not sure about every radio telescope, but there are some you can't even use cars with spark plugs around because the spark to start the combustion will get picked up. The Green Bank Observatory over in West Virginia has to keep a little fleet of diesel cars to navigate the grounds.

Which it is! Very very cool stuff :)

After all, who wouldn't?

It reminds me of the people on "smartereveryday"

And also that Tom can easily understand all the technical bits

@@matteomaximov4238 You could tell when some of the questions Tom asked were about more specific parts and John looked both slightly surprised and really glad to hear those specific questions

Did he see his own shadow though? Or are we cursed with another decade of anti science rhetoric? ;-)

Someone should draw tom scott as a badger!

A map would be cool, for places I don't know. FYI - The "Dish" is roughly 300km (180 miles) NW of Sydney (if you know where Sydney is).

In fact, I think Tom should do more of those

Totally agree! 👍

"Hey, Tom Scott here! Do radio waves actually exists?"

I loved that. I remember years ago, seeing a programme where a guy was going up to change the aircraft warning light at the top of the spire of Salisbury Cathedral, and he went up inside, on increasingly narrow and rickety spiral stairs, and the opened a door, and it cut to the view from below, and it was a tiny little hatch right at the top of the spire.

Should've been accompanied with a Clanger's whistle.

I need to rewatch it, I thought it was golf they played, but cricket probably makes more sense. The scene where they've lost the link with the rocket that's travelling to the moon & freak out becasue how are they going to get it back, cause the sky's WAY too big to scan to find the signal within the next few days, only to realise they can maybe narrow down roughly where to point the telescope to find the rocket is my favourite

@@mehere8038 Not seen the film yet but if I was looking to locate something heading between Earth and the Moon and I was on Earth I would point my telescope at the moon.

@@krashd yup :) The way they did it was great though, as one of them looks up as they realise that & says something to the others "hey guys........ I think I know where it is" or something & points & they all look up & then the camera cuts to the moon in the sky. Probably doesn't come across in reading, but the comic timing in the film makes it really work :)

I should
