light always travels at same speed for observer(3x108 ms-1)
moving clocks tick slower than stationary ones
Time travels more slowly for objects in gravitational fields
Space time gets distorted
Large objects bends space time more than light objects
Ah ha, that’s it!
We can curl time back on itself!
Link 2 regions of space with a wormhole, cunning…
Take 2 subatomic particles
Bring them together to get quantum states interlinked
Separate them, one determines the other
So far have scientists have teleported photons
Time And Relative Dimensions In Space
The tardis is bigger on inside than out… How?
Use general relativity
We can bend space and time to get a bubble bigger on side than out
Can’t use normal particles
Need exotic matter
Particles that violate classical physics
Have negative pressure, some even have a negative mass!!!
Can do endless things…
A great Father’s day present
Works using sound waves, but what is sound?
Sound is vibration
Sound waves are longitudinal
Need to make a narrow beam
Have high frequency sound, so that beam is less spread out
Speed = frequency * wavelength
Use principal of beats…
