Re: Time Energy Theory.

My understanding of physics is not great, but I have been thinking about some fundemental concepts of the universe. I understand that my theory is probably completely ridiculous, but I want to get it off my chest as it has been bugging me for the past few weeks. Also, a better answer is probably al...

Re: Looking into the Cosmos

As I recall the angle above the horizon was 15 or 20 degrees but, of course being on a hill gave us a great advantage. Trying to work out from memory, I would suggest that we were looking somewhere in a SW or W direction, but this could be entirely my imagination. Correction by those more expert th...

Re: Precession and the moon

since the moon is moving away from us(1.25 inches) each year. i assume this effects how much gravitational effect the moon has on earth. over such a long period of time. this effect has changed? 1.25 inches a year equates to the moon moving its own diameter (less than 1% of its distance away from e...

I confess I haven't used one but feedback from customers suggests that the enhancement is 'subtle' but noticeable. HTH, Steve Thanks for that. I was thinking of getting one, but quite expensive if there isn't much difference. I have seen sunspots with my filter, I expect this filter gives them a bi...

Re: Projection onto a card

Made to measure glass filters are a bit more expensive but probably better optically... Not always. Baader Solar film is colour-neutral so you observe a white Sun. Most glass solar filters impart a colour, usually blue or orange, making some features more difficult to see. Also, having a neutral co...

Re: Reflector Vs Refractor

I was wondering which would give you better views. If you compared the same sized scope in each version. Can anyone help? You can't really do a size-for-size comparison, because, in general, Reflectors are bigger (in aperture) than Refractors. For deep sky views, reflectors are generally considered...

I've had my scope for over 18 months and in that time I've only been able to use it three times. I plan to use it to view the sun this year with my trusty home-made solar filter made with Baader Solar Filter Paper. Of course my recently acquired PST has much more use.

Be wary about ordering from the USA. I will never do it again. You will get stung for VAT @ 17.5% + other import duties (about 4% I think for telescope equipment) + handling charges. You are allowed to import anything up to the value of £18 and it will need to be labelled as a gift. Our Customs & E...

It's good to have clarification but personally I thought your comment a little harsh if you were including Earthshine's contributions. Oh come on joe, this gentleman rudolfhendriques, who obviously has no scientific background whatever is pronouncing a load of total claptrap. People who have (or te...

Yes, Earthshine, I did see your earlier post, which did NOT use the SI unit Ns. It's good to have clarification but personally I thought your comment a little harsh if you were including Earthshine's contributions. I think most of this thread is total gibberish by people who know little science. Th...

Momentum. Has units of Newton seconds. (F dt = m dV) Which nobody has defined up till now. Sorry, but I did! I just used different units. Momentum = mass x velocity (this is correct) Which has units ML/T (mass x length divided by time) Force is mass x acceleration which has units ML/(T^2) (which is...

I think that a very simple fact we could chance in our idea's about time is to think dfferent about the duration of a second. Instead of saying : light travels always with 300.000km/sec trough space in vacuum, we also could say that a second always takes a duration of 300.000 lightkilometers. The s...

To be quite honest, Cliff, I think most of this thread is total gibberish by people who know little science. They are certainly shaky on basic units. Is mine wrong? If so, please tell me where I am wrong. If it looks slightly odd the way I've presented it, its because I am applying simple dimension...

That would make it Energy = Mass x speed^2. This is almost the same as Newtons work, Force = Mass x Acceleration. Mass x it's own speed (or acceleration) isn't the same as mass x speed of light^2. You work out different things with it. Well, what is the real difference between force and energy? The...
