Or is all of science now doomed because he was no wrong about the speed of light?
Or is more likely with the new information we learn from it modify our standing of things which to me is true science or am I wrong?

There were two professors on Radio 5 Live earlier, refuting the statement that nothing can travel faster than light. They talked of 'quantum tumbling' (I think that's what it was), where two particles have infinite velocity and are faster than speed of light, i.e. absolutely instant, in other words in two places at the same time, but they are the same particle.

Can someone explain this further - is it true, what use could this be etc. Thanks

A car starting from ret accelerates for 15.0 min until its velocity is 20 m/s. It then moves at constant velocity for another 20.0 min before it slows down and finally tops in another 10.0 min. Find (a) acceleration during the first 15 min, (b) the deceleration during the last 10min of its motion, and (c) total displacement

My friend tells me you can see stars from the bottom of a well in daytime. Is he talking cr ap? If he isn't could someone tell me why because I've got a degree in Physics and I can't think of a reason why!

if its NOT (!!!) a nuclear bomb...

ok, this is not a homework question and nothing to be tested in dad's old garage. I'm just asking for curiosity reasons, remembering that military aircraft are tested how they survive an EMP.
sooo how can one produce a massive EMP without polluting earth....

any idea ?

When you have motion of a magnetic in some coils. current is formed, I wonder why.

What happens inside the coil. why their electrons can move hence have current?

When a circuit is completed , the chemicals in the battery reacts and free electrons travell in the wire.

So It is said chemical energy is converted into electric energy.

However, whenever electricity is formed there must be magnetic energy surrounding it. SO, is chemical energy is converted into magnetic energy too/

If so , are electric energy and magnetic energy produced in ratio?

Indiana Jones is trapped in a maze. To find his way out, he walks 10.0m, makes a 90.0 degrees right turn, walks 5.00m, makes another 90.0 degree right turn, and walks 7.00m. What is his displacement from his initial position?

According the Law of Energy, Energy is a latent substance, cannot be created nor annihilated. The earth receives energy transmission from such as solar radiation every time and another space objects. And inside it inner core and living creatures activities will always produce and release energy too.Since the earth is relatively closed system it will be hard to move energy from it. And now of course, as we know. We have an ozone hole that permit UV arrive to earthface directly and Greenhouse Effect that blocks and traps the energy to keep it remain in this earth. In my mind, although those all conversed to another kind energy such as heat or kinetics. It will still cause an unbalance in earth system such as earthquake or maybe in the end "The earth will be blown up". What's your opinion here? Help me please...

Suppose that you are driving in a car with 100m/s and shoot a bullet with initial velocity 500m/s. Relative to the stationary observer, the bullet would be traveling at (500+100=600m/s).
Lets say you are driving at night with 100 m/s and put on the headlight, will the light beam be traveling (3x10^8 + 100) m/s relative to the stationary observer? It is apparently greater than the speed of light. Clear my confusion please..
