Time TRAVEL- A One Way Ticket?

To look at whether time travel is possible we need to distinguish between travelling back and travelling forwards. “From a philosophical point of view, we are constantly time travelling! As we age in our ordinary everyday lives, we are forever travelling into the future'.

Best app ever! You heard it right. This app has helped me get back on my quest to get things done while equipping myself with knowledge everyday.

Ashley Anthony

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!


Don’t look further if you love learning new things. A refreshing concept that provides quick ideas for busy thought leaders.

Jamyson Haug
