If time is like a straight line and the present in at the middle of that line than why do we have the capacity to remember only the past and not the future. It's based on an interesting theory but theory is only theory...

A city planner is working on the redesign of a hilly portion of a city. An important consideration is how steep the roads can be so that even low-powered cars can get up the hills without slowing down. A pariticular small car, witha mass of 1100kg, can accelerate on a level road from rest to 21m/s (75km/h) in 14,0s using these data, calculate the maximum steepness of a hill.

We know that gravitational froce causes the acceleration on bodies. Why it can't be in the other way? The acceleration of bodies towards the center of celestial bodies which are revolving around its own axis is causing the gravitational effect. Discuss it and revolutionize the Physics.

I am a bit confused about the exact nature of electric current flow.

Is electric current due to excess of electrons on the negative terminal of the cell/battery and these electrons leave terminal, flow through the conducting wire, reach the positive terminal (where there is electrons deficiency) of the cell/battery and and fill the gap

OR

The Cell, due to the electric field, sets up the conducting wire's electrons (not the ones in the chemical of the cell) move with a slow drift speed while electrical energy travels at the speed of light? or could it be viewed both ways?

I would appreciate a very clear detailed answer for this question kinnda bothers me a lot.
