In the pecking order of credibility, the only thing below Youtube comments is Facebook comments

But..... but.... it was H Simpson!!!!!

Homer CAN'T be wrong, can he???!?!?!?!?!?!

 

[Roo]

Rather then sharing the video, I went back to the video and decided to share the comment related to this.

See what H Simpson said? Some scary **** here. There's not a lot of news about this but god. Out of all the articles I've read about large asteroid potentially hitting earth and end all life, its always said to be a chance like a 1 in 300,000 or 20,000 or more. Someone said that the extinction of dinosaurs only happened because there was no technology around that time and now that we have technology now, it's said that we're not going to get hit. Although from what I heard, there's no confirmed chance on whether this asteroid will hit us or not. If it's confirmed to hit us, then well.... Commit suicide the day before it strikes?

The horror is real my friend.

I like how the size of the asteroid and the location it'll land aren't mentioned. It could be a lump of rock that drops harmlessly into the Pacific and causes a wave about 6 inches high to lap against the coasts, doing no damage at all. It won't be, of course; what it'll be is completely fictitious.

We don't have the technology as yet to say an asteroid is definitely going to hit us. In all likelihood we won't know for sure until it enters the Earth's atmosphere, by which point it'll be far too late as it'll hit the surface a second or two later. So there's nothing to worry about.

But why let facts stand in the way of talking 🤬?

@pokemonfan58 Just how gullible are you? Next time give us a credible source rather than claiming there is one somewhere but that you won't show it to us.

He doesn't have one, he said he's read in the past about asteroids hitting the earth (maybe he just fell asleep watching Armageddon) and now, to prove that it could happen, someone in a YobTub comment said it would.

A waste of a forum page, I think.

Google Apophis. That's a reason to wet the bed at night.

We do not have to worry about Apophis any more. SG-1 took care of him.

 

[Ridox2JZGTE]

Let's say Apophis will hit earth, do you guys think the government who knows about it will put it up on the news ? I don't think so, they will keep it secret and deny any chance of impact, while they will be busy trying to put all resources to avert it or destroy it.

NASA has been focusing on asteroid landing in recent years and if space agency do accelerate projects that have to do with asteroid, drilling and landing, maybe they have a reason to be in a hurry. 2036 is not far away now.

Wonder what will NASA do with possibility of Moon base/station to facilitate easier launch of space vehicles.

I don't know whether you need a hug or a slap.

Asteroid impacts are inevitable, but large impacts are exceptionally rare. But whereas only a few decades ago we were completely defenseless against such events, the potential now exists to avert catastrophe - by spotting/tracking potential impactors, to methods for deflecting them away from a possible impact, as well as steps that we might take to survive an actual impact.

In another few decades, provided we are still around, it may well be that the Earth will have a credible defensive strategy in place to deal with the event of a likely asteroid impact - it is possible (albeit somewhat unlikely) that the human race may never experience an extinction level event as depicted by Hollywood. In any case, it is not really something you need to be overly concerned about, let alone contemplate suicide if an impact event was considered very likely (or even certain).

Bear in mind too that if it were not for asteroid impacts, you almost certainly wouldn't be here right now - nature is both creative and destructive, and our path to existence has been an incredibly violent one - but the fact remains that the likelihood of us and the rest of our generation dying as a result of a giant asteroid impact is so low as to be almost negligible.

Chances are the government will know about it because of results from the many automated near earth object tracking systems run by various organizations all over the world. So the part of 'keeping it secret' is unlikely. The organizations running the NEO tracking and all the scientists thinking about asteroid impact defense will be happy to get a hefty funding increase so they won't keep the secret. And i don't think a government would be bold enough to deal with such a world scale problem by themselves.

If you are the scientist who found out about the coming asteroid, and let's say it's a big one, would you advice your government to let the news out to the public ? I think the best way is for countries with resources and tech to work together while keeping it from the public. Imagine if the collision will happen in a few years, say 2020, the year 2019 will be a very interesting if by that time our governments still couldn't guarantee a success mission to avert it or they can lie anyway.

If i would have made that discovery i would publish it -- scientists are measured by their published work. And i would know if i keep it back someone else would get the credit -- think about it: you could be the first to warn the public about a large scale impact or be the one who says: yeah, can confirm this.

In order to confirm an impact trajectory you need additional data: you need to check many old images for a sign of your object, you need to get additional observations -- possibly do radar observations to get the distance and the shape of the object to get the errors in your prediction as low as possible. The normal scientific way would be to publish the discovery and let others do the work. Just check the wikipedia page for how many people were involved in getting an accurate prediction of the trajectory of Apophis. If you want to keep this secret, you need a way to keep all this people that make a living with publishing scientific work shut up.

So if there would be a near earth object on a probable impact course discovered by some scientists we would know about it.

EDIT: and if you know a government that can keep this secret, they sure would know how to deal with that little asteroid impact threat.

 

[Ridox2JZGTE]

If that's the case, has there ever been scientific discovery being kept secret by government in the past ?

If there's actually an asteroid going to hit earth, I would hate to know that in some years, a certain huge ball of rock will land on our planet and not much we can do but hope for the governments to do something and succeed.

The Manhattan Project was shrouded in secrecy for years.

Lenses, highly useful in telescopes and microscopes, were in use for centuries or even millennia before information was published about them.

IMO, asteroids are the least of our concerns.

 

[Touring Mars]

IMO, asteroids are the least of our concerns.

Agreed... although... I'd qualify that by saying that I believe that big asteroids are the least of our concerns - it's those smaller ones that hit on a much more regular basis that pose the biggest threat... while the chances of a devastating impact on a major city remain thankfully small, there is always the risk that a small asteroid impact over a major city could be mistaken for a deliberate act (e.g. a missile strike) and inadvertently start World War III.

In 2008, an impactor just 13 ft across was discovered just 19 hours before it hit the Earth, and registered an impact equivalent to 1-2 kilotons of TNT... for comparison, the atomic bomb that exploded over Hiroshima was ~16 kT of TNT. These impacts happen 2-3 times a year, but mainly explosions occur high up in the atmosphere and nobody is any the wiser. Still, it's a rather sobering thought that a piece of rock just 13 ft across can be so powerful, and is so small as to be beyond our capability to detect it until it was less than a day away from impact.

Have a nice day. 👍

 

[tarnheld]

I doubt it. Maybe the withdrawal of research in making flu viruses into killer viruses would be an example. But i doubt it's very effective, once the word is out that something can be made, someone else figures out how to do it himself.

The Manhattan Project was shrouded in secrecy for years.

But every physicist knew that the energy release of nuclear fission (discovered 1938) could be used for a bomb. If it's so easy to keep that secret, just why didn't the nazis pull that off?

Lenses, highly useful in telescopes and microscopes, were in use for centuries or even millennia before information was published about them.

I don't think this information was kept secret on purpose, i think information was circulated in other ways back then. (I suppose you mean the time before the Ancient Greeks).

Still, it's a rather sobering thought that a piece of rock just 13 ft across can be so powerful, and is so small as to be beyond our capability to detect it until it was less than a day away from impact.

True, but our capability to detect the sleepy truck driver running full speed into traffic jam is also lacking. Nothing to fear when looking into the skies, better watch out crossing that street...

Anyone know which day SpaceX is targeting for the next landing attempt? I know it's this month sometime, thought it was early like the 2nd or 3rd, but I guess it's later in the month since we haven't heard anything. Their website just says "June".

Edit: Found it - June 26th.

That's just great news. Now let it bring us data.

Leonid Elenin discovered an asteroid on 14th of June this year using the ISON telescope. The asteroid will pass Earth on June 26th at a distance of 4.7 millions kilometers. It is automatically added to the potentially dangerous list as it meets the size and distance requirements.
The asteroid has a name- 2015 LK24. The period is 5 years.

This is some pretty scary stuff tbh. I hope NASA does come up with a plan soon to protect Earth from these Asteroids.

Won't matter if nobody wants to pay for it. That's the problem with modern society, when faced with a major problem that has the potential to wipe out life as we know it, we would all die because nobody would want to foot the bill.

 

[Famine]

This is some pretty scary stuff tbh.

Not really.

For a start 2015 LK24's orbit doesn't cross Earth's at any point. Then we need to put into context just how far 4.7 million kilometres is... It's the distance from the Earth to the Moon and back... and then there and back again...

And again.
And again.
And again.
And again.
And again.
And again.
And again.
And again.
And again.
And again.
And then one final time.

It's an incredibly long way away, even though it looks very close on the NASA image.

It's also only 35m across.

We had a closer pass from a 22m wide asteroid (2015 MA) just yesterday at 2 lunar distances. One twelve times the diameter will pass closer a month from now - 2011 UW158 at 540m and 6 lunar distances. On July 7th we'll be buzzed at less than half a million kilometres by a rock twelve times larger than 2015 LK24 - an 81m chunk called 2015 HM10...

This is a tiny lump and a long way away. It's about as scary as porridge.

So the government is trying to kill us over paying something to help prevent something that has the potential of wiping out humanity?

Well HM10 isn't anything to be worried about. NASA said that HM10 will be a miss even though they said they aren't certain, they did confirmed it's not on the risk list so yeah. Although it's quite scary that this one is bigger than Icarus.

 

[Famine]

Well HM10 isn't anything to be worried about.

None of them are. That's the point.

Sunspots today. With the 400mm through a piece of welding glass.

I need another tripod and a bigger lens.

 

[unit-one]

Nice big sunspots. Earth is waiting for CME impacts by the way.

Just don't panic, it's not dangerous.

I would hope that if one was really going to hit us 100% then the worlds nations would chip in. Problem is we might get hit without even knowing it was there. I'm pretty sure someone like Nasa already has a plan all ready to go just waiting to build it if needed.
