Thanks knight! we got to set up a group of such great information here in QL!
That's right Bolsted.
@KR if I'm right matter would be pulled into the center of the gas cloud ,because the gas cloud is the only source of mass around in that specific area? (Knowing that the gravity in space is barely or doesn't even exist?)
Just for clarification's sake.
Thelonius, Can you refute the statement that the gravitational force in the star that pulls matter into its centre of mass is dependent on the mass of the gas cloud?
Here I am trying to explain what effects the gravitation. I am not trying to bring in space-time here. You should keep to the context.
Yeah, and it's even more interesting!
I was checking around the string theory ,looking at String explanation from Professor, Michio Kaku, sounds interesting.
Thanks for the clarification !
So in other words, no specific explanation of what mass is?
@Thelonius , interesting, it's the first time I hear a explanation of the Higgs particle that way, I am still trying to fully understand the Higgs particle.
But what is "that mass" that it acquires made of?
@Thelonius, do you think they might know what or how the mass is formed , knowing that they recently discovered a particle compatible to the Higgs Boson?
Watched a video saying that the gravitational force is the force that pulls objects to each other depending on their energy not mass , or is that at the atomic level?
Bolsted, Gravity is a function of mass. The more massive the gas cloud, higher will be the gravitational force to pull in matter into its centre of mass.
On the other hand, the explosive force is a function of how many hydrogen nuclei are fusing to form helium nuclei per unit time. This is a highly exothermic reaction and thus explodes the matter outside.
These two forces act in opposite directions for billions of years till all the hydrogen exhausts. By the time, some lower elements form inside the stars. Higher elements form only during the final explosion - the supernova.
Those last questions were already answered it is just people try and turn around them!
"On the other hand, the gravity pulls in matter together acting against this outward explosive force."
Just so I can be sure, this happens knowing that gravity occurs due to the high energy produced by the explosion, knowing also that the more energy you got the strongest gravity is?
Bolsted, Its really difficult to envisage that big stars, maybe ten times the size of our sun, have extreme temperatures and pressures inside them that are the seats of nuclear fusions.
Hydrogen atoms combine to form helium and release large amounts of energy which tends to explode out the matter from inside to outside. On the other hand, the gravity pulls in matter together acting against this outward explosive force. As a result, the two forces acting in opposite directions compress matter so hard that the nuclei of lower elements, starting helium, fuse to form heavier elements in a progressive manner as the pressure and temperature increases. This effects creation of all elements that are lighter than iron. Heavier elements than iron are only formed during the supernova explosion when the star finally explodes under very high pressures in the core. The star dies and gives rises to a gas cloud that contains all the necessary elements needed for life. Now, imagine the fact that you and I are made of atoms that were made probably in the same star.
Its amazing to know that our bodies contain elements almost in the same proportions as they are available in the universe.
Now, let us answer the age old question 'who am I' 'from where have I come' 'where shall I go' and finally 'why am I here'
I guess, answering these questions won't be difficult now!
@Knight Returns tell me about it! I mean it just feels that the world suddenly makes sense and is more of a fantasy than the everyday boring routine.
And he know's how to explain in a pleasant and comic way!
I love listening to Neil deGrasse Tyson!
The way he explains our connection with the universe and the fact that each atom in our bodies was made inside a star is the most spiritual feeling anyone can have.
@nomerci thanks.
@poachedeggs and why so?
I doubt you understood that lol
Thanks blosted, good stuff!
michel jai kishen stare :/
