Collision Course
Collision Course is also known as Collision with Chronos (1977).
It couldn't be true – but it was.
The ancient ruins that dotted Earth's landscape seemed to be disobeying the laws of time, become less and less decrepit as the years went by.
Everyone had his own theory, but it was only when scientists perfected their time machines that the awful truth dawned. The ruins were getting younger every day, and the builders came not from the past but from Earth's own future, from a society occupying the same planet yet moving in time in the opposite direction, their present lying in the Earth's future, their future in Earth's past.
The two worlds were hurtling towards each other in time at a terrifying speed. Soon, unless something drastic was done, the two would collide and both would be annihilated in a horrific and extraordinary cosmic accident...
