No, nothing hit the sun, I was just wondering -- After watching Broly the Second coming (dbz) I started thinking, what would happen if something 100,000 feet all the way around hit the sun and went straight through it ; Would there be any effects on the sun or orbits?

Speed: I need a speed calculation - Whatever hits the sun goes from the earth to the sun in 27 seconds -- How fast is it going?

What you do is take this info : : Goes From Earth to sun in 27 seconds ; Goes through sun in 6 seconds : : How fast is it going, what does it do and does it slow down or speed up while goin through the sun (percentages and speed)

roughly 16x the speed of light, I think.

An object that small probably wouldn't have any significant effect on the Sun at all (which is 800,000 miles in diameter, and made of gas, so it's not like the impact would do anything). Most objects would accelerate as they got closer, due to the Sun's gravitational attraction, but since this object is already moving at 16 times the speed of light (as Musashi pointed out), it's clear we can't be dealing with a real object. Since it's already violating one law of physics, who's to say whether it will obey others?

define pass through the sun



because anything near the center of the sun wouldn't last long. the high pressure there creates densities higher than any metal we know of. it would hit and stop or bounce off. if it stayed long enough it would succomb to fusion and not be the same object.


if it passed through the sun but at an angle from the center, it would probably be deflected quite a bit.



only thing I can think of that could pass through the sun is a neutrino. some would hypothesize gravitron, but that's not real to us.

Edited to make calculations slightly more accurate, and note that yaohua has deleted this post. I don't know why, because that is in fact rather close to the correct value.(assuming I haven't botched it).
Edited again to change "beta to ß"
As yaohua has just pointed out (indirectly), our hypothetical object can get there in 27 seconds of it's time.
gamma has to be 18.25
so sqrt(1-ß^2) has to be 1/18.25
(1-ß^2)=1/333.0625
so ß^2=332.0625/333.0625
and ß=.996998
That is, your object will be travelling at .996998 of the speed of light. from our point of view

The sun has diameter roughly 4.6 light seconds. since we are working in the particles reference frame, (we can't switch half way, otherwise it was meaningless to say it travelled to the sun in 27 seconds.
6*ß=4.6 so
ß=4.6/6=.7667
Travels through the sun with an average velocity of .7667c
I would lay money that this is substantially faster than the speed of light in the sun, and your particle will emit masses of energy as cerenkov radiation.(maybe that's why it slows down). But the idea of something travelling through the sun (other than, as has been suggested, a neutrino or some other particle that's not fond of interacting- but if it's one of them, why does it slow down?) like this is just silly.

PS sorry about the mess the maths is in. I don't know how to do math symbols in BBcode (or even if it can be done). If this is incomprehensible, say so and i will fix it (or try).

As Musashi and Grey have pointed out....absolutlely nothing can be observed going at those speeds. At the speed of light, the object would have some much energy and mass, it would blow the Sun to smithereens.

It might be worth stating the object would not be from our solar system. IIRC, no object has been found in our solar system which has come from outside our solar system. [Hopefully, I am wrong on this.]

There have been calculations and simulations for star collisions. A white dwarf on a head on collision course with our sun would, due to its high density, pass through the sun mostly unchanged. The sun however would be dispersed, an event that would probably upset many people.

JFYI about using symbols in posts:

this lists symbols you can use by just pressing ALT and the number:
example hold ALT + press: 0-1-9-8 gives: Æ

There are more symbols than the ones in that list: when dropping the leading zero, you get other symbols. Like ¬ ┤ ╦ ▓

Maybe someone could bother to create (or find) a complete list of all symbols we can use and their corrseponding alt code?

Sorry for being dense, sock puppet, by how did you get that value of gamma. Using, Lorentz,

tp = yt

Where tp is the proper time, y is the Lorentz factor, t is the time as well observe it. We only know the proper time. Did you ue Lorentz contraction to get it.

we get radiation every second from other stars and galaxies





we also get debris from xtra-solar locations. [-X

Or just use the key-caps application.

Just fire up Character Map in Programs>Accesories>System Tools.

Cool. What color radiation is it really? :wink:

But has any been observed?

it's mostly in black and white, but we see blue/red/yellow stars.



There are some very long period comets (thousands of years) that have been witnessed. they travel beyond our solarsystem each orbit.


I can say without any doubt in my mind that objects from other solar systems enter ours.
