These numbers are very confusing.......but let me try what i have so far gathered from the posts below


Now we all know that our space science is not older than 200 years (not light years).......

'The closest galaxy the Adromeda is located at 23,652,000,000,000,000,000km which is equivalent to 2,500,000light years from the Milky Way galaxy.'

1 light year is the distance that light travels in one year.......correct me if am wrong??

so 2,500,000light years is the distance light travelles in 2,500,000years..............again correct me if am wrong??






How does one determine that a particular lay of light has been travelling for those 2,500,000 years and it source was imelda???


assuming that we sent a lay of light toward to some distance object like this imelda star and is reflected back,it means that the 'echo' will get back to us after 2,500,000 x 2 = 5,000,000 years.........again correct me if am wrong??

The first known practically functioning telescopes were invented in the Netherlands at the beginning of the 17th century in the year 1611 AD(see wiki).

Assuming that this very first telescope was capable of doing what today's telescopes like hubby can,and it sent some lays of light to explore the universe,those lays by now should only have travelled for 2009-1611 = 398 light years!!!

If an 'echo' of such a lay is received back today then the source can only be 398 / 2 = 149 light years!!!

Sasa hii 2,500,000 light years ya imelda imepimwa lini na kivipi??

hii quantum science mimi naona ni kama fiction!!!



If you have money that you expect to start using in five years,it now belongs in stocks.

Amazing stuff this space science thing.

@Hi-lo,I have never thought about the idea of technology developing enough speed to stop time,outside the sci-fi movies.

Based on the whole gravity pull theory,there is obviously a black hole at the centre of every galaxy to hold the stars in place.

Do you think humans will be able to develop technology to escape before they are sucked into the black holes,as its bound to happen. May be that will be the wrath of God.


I guess if you can't win with facts,you can always pen bile-laced,xenophobic rants to distract everyone.

this is quite special!!!

So anyway does that mean that we can see the past - i.e. even stuff that happened on earth???? if we developed the knowledge?

That should put to rest a lot of human mysteries - the ancient Egyptians etc.

The nerds and physicists should educate on this matter

the paradox of the dark night sky goes like this.....


if the universe is full of stars that shine bright like the sun,then we on earth can assume that it's like we are in the middle of a dense forest and every direction u turn you are bound to see a tree trunk...thus we on earth should always be showered with light all over from the billions of stars surrounding us,everywhere u turn ur eyes should fall on a star...but at night it becomes dark and the sky has no light except the moon's....how is this?

MV Ufanisi......nice name!
