How can people dig up dinosaur bones and then come to the conclusion that they know exactly how long ago they existed?
I feel like it's an evolutionary thing. Waaay back in the day, humans had to constantly fight and kill predators to survive as well as hunt and kill prey so they could eat. As time went on and we evolved and progressed to the point we're at now, the need to fight and hunt for survival is gone. But I think...
Is it because astronauts there prefer to float around at zero gravity because it's more cool??
Do we have any actual photos of planets??
Do you think man had ever left earth's atmosphere into space?
The odd against living or colonising another planet by the year 2100 are trillions to 1 against.
Firstly we don't have anywhere near the technology to create even a small colony on another planet and we won't have by the turn of this century.
Secondly I believe it is extremely doubtful that there will be...
No diapers, but urine leg bags.
Real funny incident:
Although Armstrong was the first human to walk on the Moon, Aldrin has proudly claimed he was the first "real man" to urinate on it.
Precisely the first thing he did once on the Moon and before checking the LEM landing legs (his first...
And they survived there with the help of advanced technology and re-populated the Earth and we didn't have contact with them for a good 1 million years and then we finally decided to travel to Mars. How differently would the human species have evolved to a life on Mars? Would the changes be so drastic that we...
No. But it is likely much cheaper than what it would cost if NASA did its own launch.
is it cause airplanes need air to fly? how high do you need to go up before you reach space and start floating?
If A is the area of the circle, then: A = pi × r². (i.e. the area is = pi times the radius and times the radius again)
Bigger circle will have a bigger radius, and thus bigger area, but the value of pi doesn't change.
I remember watching the Apollo Missions
They were indeed heady days
Definitely thought next stop Mars
And still do
Alas, Political upheaval had to rear its head
It is true, that Probes and Landers can do quite a sterling job
Probes have flown past and around all the planets now
With landings on Venus and Titan
