Thanks GloomyGerman, that gave me something to ask.
If the nebula is very large that does not implies that the density will be large.
Now, if for some reason the WHOLE nebula starts contracting at once I see your explanation valid.
On the other hand, if the condensation starts at the center and...
Yes, Vanadium 50, I know but the point is, once the nuclear explosion happens the rest of the cloud is blown away stopping the growth.
Why then the gas is not blown away?
I just read something about the theory of stars formation that left me puzzled. I am easily puzzled so please bear with me.
The theory goes somewhat like this:
There is s nebula (gas) that is contracting and increasing mass and pressure at its center until they are so big that a nuclear reaction...
Leaving Earth at constant acceleration will make time on board go slower.
Acceleration will take the ship closer and closer to c
Question is:
How long will acceleration act on the ship?
The time as measured on Earth or on the ship?
The final v will be greatly different. Of course, given enough...
I know that the speed of light has been measured with great precision and used successfully in many calculations.
I just wonder why this specific speed. What is the deep reason?
I am aware that if the strength of the fundamental forces is not what they are, we Earthlings would not be here; we...
