Helio replied to the thread How To Why Do Objects Burn as They Enter Earth’s Atmosphere?.Here is the current margin of error for the trajectory. The circle is the Moon's orbit. The JWST will be observing it in March and... -
Helio replied to the thread Scientists accidentally discover Earth's inner core is less solid than expected.That's a good. I can imagine that the tidal stress in the Earth, thus slowing, would occur with the outer layers of the Earth, so that...

Helio replied to the thread Scientists accidentally discover Earth's inner core is less solid than expected.I never thought it could be all that solid with temperatures estimated to be as high as 6000K. I guess the pressure is too high for it...

Researchers discovered that Earth's inner core is surprisingly viscous. Scientists accidentally discover Earth's inner core is less... -
Helio replied to the thread Scientists accidentally discover Earth's inner core is less solid than expected.Once again, more science produces improved science. They thought they had solid evidence, until someone looked closer. ;)

Helio reacted to marcin's post in the thread Explanation for cosmological red shift of light with Like.
Your Planck constant h decreases with time, so your frequency f=E/h increases with time (for E=const), so your wavelength λ/c=1/f=h/E...

Helio replied to the thread Need some help.Ok. But that’s one line I can’t follow. Newton’s work is consistent with GR up to a point. How a Newtonian c.g. varies in GR would be...

Helio replied to the thread Need some help.Jzz, I think you are referring to Cat's link. Your challenge to GR will require some powerful math to show how core densities can solve...

Helio replied to the thread Weapon of big bang.At that concentration, temperatures are in the many trillions of degrees, which is too hot for even quarks. Thus only energy was in the...
