swansont ,can you pls xplain it a little bit...how he used stellar aberration???

ya...it's true..but spikerz66 if the big bang theory is correct then the universe will collapse some time due to gravitation.....so there must be a thery like big collapse or stuff like that...pls let me knoe if there is any such theory...

can anyone pls give me links for basic actionsript tutorials???

i think your idea "Common sense tells me that the further from the Sun, the larger a planet can be" is wrong as then..what will you say about pluto??

how sceintists of 17-18th centuary measured the speed of light????they cannot do it by distance/time as then by the time they have measured 1s light would travel far ahead of them to mesure(300000km)..and they didn't have eqipments to measure 1/100000th of second that time..even if they did ,by the time they mesured it,it should move ahead.....so how did they managed to do it.. ???????? :confused: :confused: pls help me out .....

according to eniestien,matter bends space..so what woud happen if you put more and more stars to it...it will cuve and curve untill...untill it encloses it self....i.e.universe has a shape of a sort of sphere....you will run out of new places to see but you will never find a end...that's what i think..pls correct me if i am wrong....

so martin,does that means that if we compress earth to about 1cm radius..it will become a black hole???

thanks everyone for encouraging me.... now i have a very basic understanding of the universe...

for last two days,i am reading the posts in this forums..but the more i read,the more i get confused....can someone pls tell me about what exactly is the structure of universe?????how was it created and how will it get destroyed??????how did the scientists figured it out????is there any proof of the modern model of universe????what are black holes,worm holes and singularity????pls help me as i am getting severe headache boz of this...... :confused: :confused: :confused:

pls tell me something about schwarzschild radius????i know it's basics but what is the formula for finding it????what is the schwarzschild radius of earth????

anti proton spaceship.....hmmmmmmmmm..let me think....you cannot make one as your spaceship will be destroyed immediatly because of the energy of the annihilation of anti proton..anyways,it will take at least 1000 years to see the first anti proton spaceship...

thanks both of u....now i get it..

hi, this is my first post..i am a 9th grader so don't pounce on me if you find my questions idiotic...i want to learn..anyways,one problem, earth's rotational speed is 493.8m/s..now if i jump from a point on earth's surface so that i stay in air for 1 s..when i land , i should end up 493.8m away from where i started as by the time i reach land ,earth should have moved 493.8m ahead(or behind) me..but i land on the same point from where i started !!!!!!!!!!!! how can this happen as earth will surely move ahead in 1s.... pls explain this...
