Even if the Tunguska event was 200x, let alone 2,000x more powerful than the bombs my country dropped on Hiroshima and Nagasaki, how did it not wipe out life on Earth, and how come only a few people noticed the event actually happen? I know it was in the desolate Siberian wilderness, populated by some farmers and Tsarists political prisoners, but still...

The Tunguska explosion is estimated to be 33 times the blast at Hiroshima or 500 kilotons.
https://en.wikipedia.org/wiki/Tunguska_event#:~:text=The%20exploding%20meteoroid%20was%20determined,release%20of%20approximately%20500%20kilotons.

It's also estimated as up to 30 MTons
"The 30 Mt (130 PJ) estimated upper limit blast power of the Tunguska event could power the same average home for more than 3,100,000 years."
from
https://en.wikipedia.org/wiki/TNT_equivalent

But the detail doesn't matter.
Most of Hiroshima survived the blast.
Almost all the damage was confined to sticky out bits that people had put there.
The flat bits were generally  fine.

That wiki page lists plenty of earthquakes etc that were much bigger than a thousand times the upper bound to the estimated energy from Tunguska.
A notable example is an hour's worth of sunshine: 104000 megatons.

No one actually knows what happened at Tunguska as it is speculated to be an impact event but there is no crater.  So for all we know this might have been a warp core explosion

All impacts create a crater whether it is an inch or thousand miles across

So for all we know this might have been a warp core explosion

That would have left radioactive debris.

All impacts create a crater whether it is an inch or thousand miles across

Nobody said otherwise.

Wrong son as there is just no telling what would power an alien ship.  Again you fallibly link everything that could be to what we have now.  The fact is that Tunguska is labeled as an impact yet these is absolutely no evidence of an impact happening.  There is also an apparent lack of vegetation still at the apparent ground zero with no explanation.

Wrong son as there is just no telling what would power an alien ship.

But a "warp core explosion" is a feature of a documented sci fi series- Star Trek It does not have any other meaning.
It's not alien.
We do know what it does.

The fact that it's imaginary leads to questions about you raising the idea; but my point is still correct.

no evidence of an impact happening. 

Apart from all the trees blown outwards.

Again you fallibly link everything that could be to what we have now

You should try to shake that hallucination; it's not helping you.

Warp core is fiction and as such can be anything, so it is not necessarily nuclear as you claimed.  I just used that as an example, besides dilithium is not really nuclear son.  LOL you might know more about Sci-Fi than I do, so are you in uniform?

All impacts leave an impact crater whether on the moon or the Earth, often on the Earth these craters get eroded away, there was never any evidence of an impact crater at Tunguska

You should stop referencing RAID hard drives as modern, then again I do not really know what you have to play with over there so to you RAID might be a big deal.

CIAO

[Bored chemist]

You can leave a crater in a forest without moving much earth.

I used it once to illustrate the idea of redundant storage. (which you still don't seem to understand). I did not say it was modern.
You have used the word more than I have.
Perhaps you should get a mirror.

Warp core is fiction

And you introduced it into a science discussion...

as such can be anything

No; it can be anything the author says it is- and they said it's an antimatter engine. So failure of the engine would lead to radioactive debris.

"

dilithium is not really nuclear son

"
Of course it isn't mother; it can't be nuclear; it isn't real.

The "dilithium crystals" are another bit of sci fi.
Did you not know that?

All impacts leave an impact crater

When they hit water, that's debatable...

No son we do not know what a warp core explosion does.  I of course know that warp cores are not real and as such actually do nothing.  However we will give you time to explain what warp cores do and explain how they are nuclear as you claimed.

Now trees blown down and out are an indication of an airborne blast and an impact would leave a crater.  There was and is no crater, there never was.  They speculate that the body blew up in the air from atmospheric friction, but this would not happen as the friction would just burn up the object on the way down not burst it, unless there was a fuel source of course.

REMEMBERING TUNGUSKA: A MYSTERY EXPLOSION THAT BAFFLES THE CIA OVER A CENTURY LATER
Theories Continue to Run Wild As Scientists Try to Explain the 15 Megaton Blast That Shook Sibera
RYAN SPRAGUE·JULY 1, 2021
FEATURES
IDEAS
SCIENCE
Locals felt their skin burning from forty miles away. Windows shattered within a hundred-mile radius. It was an event that shook Siberia and left roughly 80 million trees completely flattened. Something, with the destructive force of over a thousand Hiroshima explosions, exploded in Siberia. The problem is that no one knows what it was.

Whatever happened over the Tunguska River was seen, heard, or felt by thousands of people. Although several theories have been brought forward to explain it, the Tunguska event remains a mystery over a hundred years later.

According to many reports that would eventually be collected, on the morning of June 30th, 1908, a blueish-white light lit up the entire sky. The Evenki native people, who lived in the hills just beyond the Tunguska River, watched as a streak of colored light shot across the sky on a trajectory of impact. After about ten minutes of watching the light, there was a bright flash and a thunderous explosion that literally knocked them off their feet

[Bored chemist]

So, you still don't understand that the air impacted upon the trees.
The rest of your post wasn't any better.

No son we do not know what a warp core explosion does. 

But mum, I keep telling you; we  do.
The only meaning that has is in this sci fi show.
And we have a video of a warp core explosion.

And we know that it's a matter/ antimatter reaction.
And we know that the annihilation of matter gives rise to radioactive debris.

Did that impact leave a crater in them, or were you wrong about this?

There is no video of a warp core explosion because there is no warp core.  However the 9th US Navy ship to be called Enterprise is under construction at Huntington Ingalls at Newport News Virginia at the moment. This version does has two radioactive cores.  Have you ever been to Virginia?

As for more meaning to warp drive you can find some here

Did anyone check the bodies of those who were knocked over by the impact to see if that impact had left a crater?

(atmospheric) friction would just burn up the object on the way down not burst it, unless there was a fuel source of course.

The Chelyabinsk meteorite is the second most damaging explosion after Tunguska - only this time there are many images from dashcams and security cameras. It definitely exploded, around 12-15 miles high, and several pieces have been found, none of which looked like pieces from the Enterprise (either the interstellar or the maritime version). No fuel source has been identified.

Actually both are plausible because we do not know what the aliens are using for power.  However you said that there was video of a warp core explosion, then I said that there is no video of a warp core explosion because there are no warp cores on star trek, I hope that you can rectify what is real vs fiction.  Tunguska was before star trek and there is still no explanation for what happened.

I find it literally comical that the CIA does not know what happened at Tunguska but that you do.

I remember that, amazing videos.  Which raises the question, why always Russia?  How big was the blast zone as compared to 1908, also witnesses in 1908 said that the sky turned blue white for ten minutes before they were knocked over.  10 minutes is an eternity as typically there is a streak and flash of mere seconds like the video above

[Bored chemist]

We know that they will not be using an imaginary engine, and yet that's what you chose to suggest.

I hope that you can rectify what is real vs fiction.

It seems only one of us can manage that.

I find it literally comical that the CIA does not know what happened at Tunguska but that you do.

All I have said is three things:
(1) There was a impact which knocked the trees down- they were impacted by something.
(2) It was not radioactive, (at least, by the time anyone checked).
(3) It was not an imaginary thing from Star Trek.

I'd imagine the CIA probably knows more than that.

But you  don't seem to have grasped the 3rd point- so I know more than you do.

[evan_au]

ten minutes before they were knocked over.  10 minutes is an eternity as typically there is a streak and flash of mere seconds like the video above

In Chelyabinsk, people reported a delay of about 5 minutes between the explosion and the windows getting blown in.

You can work it out: If the altitude was 20miles/30km, and it was low on the horizon, so it may have been 80km horizontally. so a total of 85km
- The speed of sound in air (at sea level) is 300m/s, or 3s/km.
- That implies a delay of around 250 seconds, or 4 minutes.

Tunguska left a lot more flattened trees, over a large area, so Chelyabinsk (estimated 20m diameter) was a long way behind Tunguska (estimated 50m diameter) in explosive power. If they were similar composition and travelling at the same speed, you expect the larger one to deliver about 16 times the kinetic energy.

- Of course there have been much larger impacts in prehistoric times. Meteor Crater was formed about 50,000 years ago.

Again if you drop a pea in the sand it makes a bigger crater than at Tunguska as there is no crater, never was.  Furthermore the witnesses said that the sky was blue white for ten minutes before the blast, the light is traveling at light speed not the speed of sound so their is no delay that can be noticed by a human.

It's big.
Though, as usual, you are simply wrong.
