A railroad diesel engine weighs four times as much as a freight car. If the diesel engine coasts at 13 km/h into a freight car that is at rest, how fast do the two coast after they couple?

First things first. Big bang. If the big bang caused nothingness to form...then what was there before this supposed explosion? To me big bang is very skeptical. You can't say nothing was there. because then nothingness was created from nothing. That makes since. But where did the first matter ever occur? This spontaneous explosion that just happened with nothing? To me the origins of the universe can never be truly determined. We can only speculate.

Now the earth. Same thing. despite the fact the earth was formed much much later, how can we know how it was formed? How did all of these coincidences align up and where did the first trace of any life ever come from? To me something can't form from nothing. So I wonder if maybe there really is a higher power that created it all? Just a thought.

And how can we ever be sure where it all came from? This happened billions of trillions of years ago. Longer ago then that.

There are some mysterious incidents occuring & the news channels are bringing up many such interesting informations & some hidden facts & unexplainable incidents.Many well reputed Scientists & astronauts agree that there are aliens. ( And they have reasons to agree, they say there are proofs )

I believe that we humans have not been able to explore the entire Universe so how can we be so sure of the non - existence of aliens. There are millions of galaxies & solar systems. When there is life on earth & we & several species of living creatures exist then it is possible that life might be on some other planet not necessarily in our solar system & it is also possible the environmental conditions are suitable for their existence but might not be suitable for ours !! Who knows ??.

Thanks for your kind response :)
