Always was is one and the one always is. This video presents a mirror aspect to one. The only aspect is one no smoke and mirrors.Did you realise that what you posted makes no sense?
May be they just think they know, or pretend to know to gain authority or some credential over their audiences.And how do they know that?I don't know it may have been just a saying.
We seem to have drifted from the original question of why double the speed =4x the energy.Good point.
It wouldn't make ice cream taste better
And what made your god?They say he/she has always been.
When you say ideas, do you mean hypothesizes based on our current understanding of physics? Because if you do (and I cannot stress this enough), I will happily accept the most scientifically-sound/agreed-upon hypothesis as an answer.No, I meant there is some history, various ideas that are now discredited, some sideline discussions that will surely pop up along the way, more general discussion around the topic etc.
Since I have so many more questions similar to this one, can I post all of them at once on a single thread? Like, is that allowed? Asking multiple questions in a single thread?I'm not a moderator but the following seems reasonable:
Tidal forces wouldn't effect the answer significantly. The Roche limit( as measured in multiples of the primary's radius) is dependent on the relative densities of the bodies.
Anyway, other articles consider the journey toward the sun to be over in about 65 days but that seems to be because they reckon the tidal forces from suns gravity would rip the planet apart before we even reach the outer edges of the sun.
That figure assumes that, yes, just like it would take a feather the same time to get going.This works out to be about 64 days.Have you taken into account that the earth is starting from a stand still it will take some time to get going?
If the earth stopped orbiting the sun. This is a hypothetical question and may have an interesting answer. Can anyone do the math and reveal the answer as to the arrival velocity and time period for the earth as it makes contact with the sun. The earth has great mass so I'm sure it will be slow getting started on its journey to the sun. I haven't calculated the speed or time for this event as I have no understanding of the equations involved. I hope someone can give the answer?The quick and dirty method of computing the fall time is to assume the Earth's orbit is an extremely eccentric ellipse with the Earth's present distance being at perihelion. This puts the Semi major axis at half the perihelion distance, and you can just calculate half the period of such an orbit. This works out to be about 64 days.
This is a hypothetical question and may have an interesting answer.It may have an interesting answer? You're not planning to try it are you? We can't encourage these kinds of experiments.
575 km/sec in fact which is the escape velocity of sun minus escape velocity of solar system from Earth. This is about 2 million km/hr or 1,200,000 mphThere's a risk he was using a complicated solar system with all the masses of the planets, asteroids and whatever but let's just assume he was considering the sun as the only mass of interest. Never do a claculation yourself if someone else will do it for you.
I'm not sure but I think it would take 6 months (half a year) to fallMaybe two months at best. 6 gets us all the way to the far side, and that's without any change in speed all the way.
and it would hit the sun at the current orbital velocity (about 67000 mph).615 km/sec in fact which is the escape velocity of sun minus a little for escape potential from Earth distance. This is about 2.2 million km/hr or 1,380,000 mph
If the earth started out where Jupiter is it would build up much more velocity just throwing that out there.Negligible difference. Maybe 616 km/hr
The earth has great mass so I'm sure it will be slow getting started on its journey to the sun.Usually the intuition is that big things fall faster than little things (feathers and such), but Galileo showed that the mass of the falling object has negligible effect on the time it takes to get to the much more massive thing attracting it.
