Archief - Komeet raakt de aarde.
Het archief is een bevroren moment uit een vorige versie van dit forum, met andere regels en andere bazen. Deze posts weerspiegelen op geen enkele manier onze huidige ideeën, waarden of wereldbeelden en zijn op sommige plaatsen gecensureerd wegens ontoelaatbaar. Veel zijn in een andere tijdsgeest gemaakt, al dan niet ironisch - zoals in het ironische subforum Off-Topic - en zouden op dit moment niet meer gepost (mogen) worden. Toch bieden we dit archief nog graag aan als informatiedatabank en naslagwerk. Lees er hier meer over of start een gesprek met anderen.

zieter wel realistisch uit opt eerste zicht :/

Skarr zei:lol, zag er idd realistisch uit
realistisch my ass.
- zo dicht bij een meteoorinslag staan en overleven? i don't think so
- had het echt geweest had het wel op het nieuws geweest
- de auto die volgt rijd gewoon over het wrak, bij een echte inslag zou daar een krater van een tiental meters omtrek en diepte zijn
- blijkbaar zijn ze niet echt bezorgd om de inzittenden, maar roepen ze liever "wooooooooooooooh, did you see that"

Ga naar http://www.standaard.be/
Ga naar WEB TV , in het menu links
en zoek : Australische hemel verlicht door meteoriet
Bekijk de film, over dit gaat het, en ik denk toch niet dat dit alle dagen voorkomt.

betreft zwart gat,naast de deur in kosmische termen dus..200 lichtjaar ofzo
ge hebt daar een ster groter dan onze zon voor nodig(die uitdoofd)...de meeste sterren 'naast de deur' zijn te klein
het grootste deel van een zo een kleiner object brand op in de dampkring,dus in de ruimte zal ie wel een pak groter geweest zijn..toch grote impact, want zo dingen gaan soms aan 10 000den km/h en bij botsing kan daar enorm veel kinetische energie vrijkomen

voorbeeld..nen strandbalmeteoor van 1m (solide rots) op rotsgrond, 50km/s,1km afstand
Your Inputs:
Distance from Impact: 1.00 km = 0.62 miles
Projectile Diameter: 1.00 m = 3.28 ft = 0.00 miles
Projectile Density: 3000 kg/m3
Impact Velocity: 50.00 km/s = 31.05 miles/s
Impact Angle: 45 degrees
Target Density: 2500 kg/m3
Target Type: Sedimentary Rock
Energy:
Energy before atmospheric entry: 1.96 x 1012 Joules = 0.47 x 10-3 MegaTons TNT
The average interval between impacts of this size somewhere on Earth is 0.3 years
Atmospheric Entry:
The projectile begins to breakup at an altitude of 71300 meters = 234000 ft
The projectile bursts into a cloud of fragments at an altitude of 60000 meters = 197000 ft
The residual velocity of the projectile fragments after the burst is 47.7 km/s = 29.6 miles/s
The energy of the airburst is 1.77 x 1011 Joules = 0.42 x 10-4 MegaTons.
No crater is formed, although large fragments may strike the surface.
Major Global Changes:
The Earth is not strongly disturbed by the impact and loses negligible mass.
The impact does not make a noticeable change in the Earth's rotation period or the tilt of its axis.
The impact does not shift the Earth's orbit noticeably.
Air Blast:
What does this mean?
The air blast at this location would not be noticed. (The overpressure is less than 1 Pa)

ééntje van 5km doorsnee in ijzer op hoek 60 graden en 50km/s op rotsgrond,150km afstand
catastrofa
Your Inputs:
Distance from Impact: 150.00 km = 93.15 miles
Projectile Diameter: 5000.00 m = 16400.00 ft = 3.10 miles
Projectile Density: 8000 kg/m3
Impact Velocity: 50.00 km/s = 31.05 miles/s
Impact Angle: 60 degrees
Target Density: 2500 kg/m3
Target Type: Sedimentary Rock
Energy:
Energy before atmospheric entry: 6.54 x 1023 Joules = 1.56 x 108 MegaTons TNT
The average interval between impacts of this size somewhere on Earth during the last 4 billion years is 2.2 x 108years
Major Global Changes:
The Earth is not strongly disturbed by the impact and loses negligible mass.
The impact does not make a noticeable change in the Earth's rotation period or the tilt of its axis.
The impact does not shift the Earth's orbit noticeably.
Crater Dimensions:
What does this mean?
Transient Crater Diameter: 88.5 km = 55 miles
Transient Crater Depth: 31.3 km = 19.4 miles
Final Crater Diameter: 159 km = 99 miles
Final Crater Depth: 1.36 km = 0.846 miles
The crater formed is a complex crater.
The volume of the target melted or vaporized is 5040 km3 = 1210 miles3
Roughly half the melt remains in the crater , where its average thickness is 819 meters = 2690 feet
Thermal Radiation:
What does this mean?
Time for maximum radiation: 3.47 seconds after impact
Your position is inside the fireball.
The fireball appears 260 times larger than the sun
Thermal Exposure: 1.37 x 1010 Joules/m2
Duration of Irradiation: 2260 seconds
Radiant flux (relative to the sun): 6070
Effects of Thermal Radiation:
Clothing ignites
Much of the body suffers third degree burns
Newspaper ignites
Plywood flames
Deciduous trees ignite
Grass ignites
Seismic Effects:
What does this mean?
The major seismic shaking will arrive at approximately 30 seconds.
Richter Scale Magnitude: 10.1 (This is greater than any earthquake in recorded history)
Mercalli Scale Intensity at a distance of 150 km:
X. Most masonry and frame structures destroyed with their foundations. Some well-built wooden structures and bridges destroyed. Serious damage to dams, dikes, embankments. Large landslides. Water thrown on banks of canals, rivers, lakes, etc. Sand and mud shifted horizontally on beaches and flat land. Rails bent slightly.
XI. As X. Rails bent greatly. Underground pipelines completely out of service.
Ejecta:
What does this mean?
The ejecta will arrive approximately 177 seconds after the impact.
Your position is in the region which collapses into the final crater.
Your position is beneath the continuous ejecta deposit.
Average Ejecta Thickness: 163 m = 533 ft
Air Blast:
What does this mean?
The air blast will arrive at approximately 455 seconds.
Peak Overpressure: 1.25e+07 Pa = 125 bars = 1780 psi
Max wind velocity: 2830 m/s = 6340 mph
Sound Intensity: 142 dB (Dangerously Loud)
Damage Description:
Multistory wall-bearing buildings will collapse.
Wood frame buildings will almost completely collapse.
Multistory steel-framed office-type buildings will suffer extreme frame distortion, incipient collapse.
Highway truss bridges will collapse.
Highway girder bridges will collapse.
Glass windows will shatter.
Cars and trucks will be largely displaced and grossly distorted and will require rebuilding before use.
Up to 90 percent of trees blown down; remainder stripped of branches and leaves.

Click here for a pdf document that details the observations, assumptions, and equations upon which this program is based. It describes our approach to quantifying the important impact processes that might affect the people, buildings, and landscape in the vicinity of an impact event and discusses the uncertainty in our predictions. The processes included are: atmospheric entry, impact crater formation, fireball expansion and thermal radiation, ejecta deposition, seismic shaking, and the propagation of the atmospheric blast wave.

Ik zou mijn geld er niet op durven zetten, zeker niet bij die nieuwere reactors.GTM zei:
Die hebben 2 wanden, minstens 2 meter van elkaar.
Elke wand is +50cm voorgespannen beton, met gigantische hoeveelheden wapening
Als ge ergens een momentdiagrama kunt vinden van zo'n constructie valt da vrij gemakkelijk uit te rekenen.
