To try to write a grand cosmical drama leads necessarily to myth. To try to let knowledge substitute ignorance in increasingly larger regions of space and time is science.

We have to learn again that science without contact with experiments is an enterprise which is likely to go completely astray into imaginary conjecture.

I have always believed that astrophysics should be the extrapolation of laboratory physics, that we must begin from the present universe and work our way backward to progressively more remote and uncertain epochs.

I have never thought that you could obtain the extremely clumpy, heterogeneous universe we have today, strongly affected by plasma processes, from the smooth, homogeneous one of the Big Bang, dominated by gravitation.

I have no trouble publishing in Soviet astrophysical journals, but my work is unacceptable to the American astrophysical journals.

If a problem is too difficult to solve, one cannot claim that it is solved by pointing at all the efforts made to solve it.
