A Trillion Space Telescopes Unlock Mysteries of the Universe

Science is a wonderful tool, but once you start thinking of it in absolutes you become ignorant and biased. Stay skeptical, not of aliens, but of your accepted perception of reality through any medium or instrument. Edit : So, my point? If you can't trust light, it is not a tool for measurement. If it is not a tool for measurement, what is? I say nothing, in reality. Though we can enjoy our delusions of grandeur and believe that we can measure infinity, I would like to think that we are the infinite. I could be wrong, but I'm holding on to a belief, not a formula or constant, and beliefs are more flexible.

I think my first book about Einstein was in my early twenties and I was fascinated about a subject. Ten years ago or longer it had to be...
I was a stay at home mom and was bored from my every day chores and hobbies so I went to the library and checked out some books. Struggling with grief and still mourning I began to get my mind really busy. I got a few books but one in particular had me stumped for days. I could not stop reading about "Time".

That book begat more books and I have been an avid reader since.

How does one define reality, really? Once you allow your mind into the depths of time, space and reality one realizes the only definition of reality remains in the eyes of the beholder. It is all about perception and nothing more.

Wild stuff to ponder, that is for sure.

I would love to be able to afford a nice telescope so I can gaze at the cosmos and speculate. My kids and I lay flat on our backs in the back yard or on the deck and talk about what we "think" we see. I guess if I had a telescope it would change our talks of the night sky.

Good thread!! xoxox

The gravity of a massive object can "bend" light around it.
So by understanding how this process works, scientist can use the "gravitational lense" to see objects behind a galaxy, by piecing together the light that has been "bent" in our direction.

Actually the only thing being bent is space, the light is traveling in a straight line through bent space. If you were standing in this bent space the light would appear to be straight. You cannot "bend" light but it can be refracted. Gravitational lensing and standard optical lensing through glass are two different things. Unless you believe that the glass itself is also bending space time, in fact it may be...

And yet a clear picture of our moon is huge challenge...

Or Sirius A, or α Centauri A, or ...
