Please ignore my question if you mock over stupid questions... Keeping in mind: 1) The distance traveled by light in one year is one light year 2) Material objects can not attain the speed of light 3) Solar system is VAST, but at the same time it may be smaller than even a single star far far away from us. Imagine the size of that star system, and then the distance between solar system and that star system (simply billions of billions of billions of light years from us.) Now the question is : Can we happen to know what is out there in those systems (with todays technology we can't). But as stated earliier; it is impossible for a material object to attain the speed of light, so does that mean we can never have the technology to overcome this constraint. Is it the limit...?
