It's faster than the speed of light; therefore it is impossible.
No, I could not.
It Could Depend. But it could be possible.
Unless time travel is possible, no. the big bang happened over 5 billion years ago, while humans have only been alive for about 100,000 years, there is no possible way we could have caused it.
The universe is actually about 15 billion years old. I'm not sure where you got the statistic that the Hubble Space Telescope can see 20 billion light years into space; I think you're off by a factor of three or so.
that could be
There are thought to be between 200 billion and 400 billion stars in our galaxy. So for every star, there could be several planets in orbit. This is just our galaxy though, there are then thought to be 100 billion galaxies or more, so total number of stars in the universe is massive.
Sound travels at around this speed in air.It's possible that you are thinking of something else that could travel at this speed, but sound was the first thing that I thought of.
Light could travel seven and a half times around the world in one second.
from zero to over 100,000 miles.
Ten seconds.
Probably not. Well, on second thought... it could be!
1 billion seconds / 3600 / 24 / 365.2422 = 31.69 years
I thought I could come up with a better sentence but this is all I can do. He gave some thought to the idea of improving the sentence. The councilman made his decision and never gave the matter a second thought.
Yes... into the future at one second per second. Current physical theory says that there could be "closed timelike paths" (scientific doublespeak for "time travel" if certain conditions were met... unfortunately, these conditions are not physically realistic and could not possibly occur in a finite universe. As far as we know, time travel is impossible.
Well you could just say "billion" job done. 1/2 second,If you started at zero and counted one digit every second, it would take, obviously one billion seconds.So how long is that:16,666,667 minutes11,574 days31 1/2 yearsHopefully you have something more constructive to do with your time?
Because they thought they could travel to Asia by sailing east.
400 billion seconds. (almost thirteen thousand years) By the way there are probably no more than 200 billion stars in our galaxy...
