### If a star 600 hundred light years away went super nova how big would the explosion have to be for people to see it is less than 600 years?

I mean the bigger the bigger the explosion the faster we see it I know that for example if the explosion covered an area of 500 light years we would not have to wait 600 years to see it

and that we'll all be dead long before the human race makes any notable achievement other than putting probes on planets and satellites in space that orbit earth.

i wonder how much money is needed or required in order to 'speed up' the entire thing,  space exploration surely must be at the forefront of human beings needs.

we must surely be investing all we have,  and more on just this.

to get the heck off this planet and find new places to visit..

yet we can barely reach the moon.  how upsetting.
